Gucagura umutsi w'amaraso n'ugucagura umutsi w'amaraso wo mu nda (AAA)

Igitigiri c'ivyihutirwa gitandukanye hakurikijwe igihugu. Iyi paji ikoresha 911, inomero ya Leta Zunze Ubumwe za Amerika na Canada. Ibindi bihugu vyinshi bikoresha 112, 999 canke uwundi mubare. Rondera umubare w'igihugu cawe.

Gucagura umutsi w’umutima n’ugucagura umutsi w’umutima mu nda (AAA) ni bibiri mu bibazo vyihutirwa vy’umutima n’imitsi bifata igihe kirekire cane mu buvuzi, bishobora gutuma umuntu ava amaraso yo mu mutima canke akabura ingingo mu minota mikeyi. Kubera ko umutsi w’amaraso (aorta) ari wo mutsi nyamukuru utwara amaraso afise umwuka mwinshi uva mu mutima ukaja mu bwonko, mu maboko, mu bihimba vy’umubiri no mu maguru, amarira yose yoba ari mu ruhome rwawo rw’imbere (dissection) canke akaturika mu gice cagoyagoya (ruptured aneurysm) bisaba ko umuntu abagwa vyihuse. Ubutabazi bwa mbere bwibanda ku kumenya ningoga ibimenyetso vy’indwara y’umutuku, guhamagara abaganga b’ivyihutirwa bafise imburi zitomoye z’imitsi, gutuma uwo muntu aguma ahagaze rwose kugira ngo umuvuduko w’amaraso ntaduke, no kwirinda imiti nk’iya aspirine ituma amaraso ava cane.

Ntuhe aspirine kubera ububabare bwo mu gikiriza canke bwo mu mugongo butunguranye .

Naho guta aspirine ari uburyo busanzwe bwo kwivuza umuntu akekwaho kuba afise indwara y’umutima itewe n’ugutera amaraso mu mutima, ntiwigere utanga aspirine, ibuprofen, canke ikintu cose co gutuma amaraso agenda neza iyo wikeka ko umutsi w’umutima wacitse canke ko umutsi w’umutima wacitse. Mu gihe umuntu afise ingorane zihutirwa zo mu mutsi w’amaraso, uwo muntu arava amaraso biciye mu ruhome rw’umutsi w’amaraso rwacitse, kandi imiti igabanya amaraso canke igabanya amaraso iratuma amaraso adashobora gutera amaraso, kandi igatuma abantu bapfa cane iyo babazwe. Nimba ububabare bwo mu gikiriza buza buca bushika, bumeze nk’ibara ry’agahomerabunwa canke ry’ugutabura rikaja mu mugongo, canke rigatera imitsi itandukanye hagati y’amaboko y’ibubamfu n’ay’iburyo, n’uhagarike aspirine maze ubibwire abaganga ubwo nyene.

Ivyo ubikore ubu

  1. Hamagara inomero y'ivyihutirwa yo mu karere kawe ubwo nyene maze umenyeshe ko "Ukekwa ko hari ikibazo gikomeye c'umutsi w'umutima" canke "Ukekwa ko hari ikibazo c'umutsi w'umutima." Hamagara 911 muri Leta Zunze Ubumwe za Amerika na Canada, 112 mu Bumwe bw'Uburayi bwose, 999 mu Bwongereza, canke usuzume vyose inomero z'ivyihutirwa. Bwira mu buryo butomoye uwo murungika nimba umurwayi afise ubumuga buzwi bw’umutsi w’umutima, indwara ya Marfan, umutsi w’umutsi w’umutima ugira amabara abiri, canke ububabare butunguranye bwo gutabura mu gikiriza, mu mugongo canke mu nda hamwe n’ugucika intege, kugira ngo bashobore gutumaho imodoka ifasha abarwayi mu buzima buteye imbere maze bamenyeshe ibitaro bifise ububabare bw’umutima canke bw’imitsi.
  2. Shira umuntu ahagaze ku mugongo (canke mu kibanza ciza co kwicarako iyo afise impwemu nke) hanyuma ushireho akaruhuko k’umubiri. Ntureke uwo muntu ahaguruke, agende aja mu bwogero, canke ngo asohoke ajane mu modoka itwara abarwayi. Igihe cose umuntu akora cane, akagira umubabaro canke ahagaze bukwi na bukwi, bituma umutima n’umuvuduko w’amaraso bitera cane (shear stress) bishobora gutuma amarira y’umutsi w’amaraso canke hematoma y’inyuma y’igifu imeneka burundu ikaja mu gikiriza canke mu nda.
  3. Uhagarike ivyokurya vyose, amazi, amazi, n’imiti yo mu kanwa, cane cane aspirine na nitroglycérine. Gumana umuntu ataco afata mu kanwa (NPO) kuko bizosaba ko bamutera umuti w’ububabare bwihutirwa (anesthésie générale) ubwo nyene ashitse mu bitaro. Ntuhe umuti witwa aspirine, clopidogrel canke umuti witwa nitroglycérine wo munsi y’ururimi kiretse iyo umuganga akubwiye mu buryo butomoye ko ata ndwara y’umutsi w’amaraso ushobora gutera.
  4. Guma umuntu atuje, acereje, kandi afise ubushuhe busanzwe mu gihe uzimya amatara yaka cane kandi ugabanura ubwoba bwo mu mutima. Ubwoba n’ububabare bukomeye birekura imipfunda myinshi y’umubiri (epinephrine na norepinephrine) mu maraso, bikaba bituma umuvuduko w’amaraso systolic n’uruhome rw’umubiri rutera hejuru. Vuga n’ijwi ry’ubute kandi rihumuriza, urekure imikanda canke amaboko afatanye, hanyuma umupfuke gatoyi n’igitambaro kimwe kugira ngo ntahinda umushyitsi ataco umushushe cane.
  5. Suzuma imivuduko y’amaraso mu maboko yompi maze ubone ubugoyagoye bwose bwo ku ruhande rumwe, ububabare, canke itandukaniro ry’umuvuduko w’amaraso. Nimba ufise igikoresho co gupima umuvuduko w’amaraso mu nzu, pima umuvuduko w’amaraso mu maboko yompi y’iburyo n’ay’ibubamfu mu gihe urindiriye abaganga, hanyuma wandike imibare. Numve mu bugwaneza umuvuduko w’amaraso ku maboko yompi canke usuzume nimba ukuguru kumwe guturutse gutukura, gukonja canke gusenyuka, kuko gucagura umutsi w’amaraso (aorte) akenshi bizibira amashami agaburira ukuboko kumwe, ubwonko canke amaguru.
  6. Ufungure inzugi, ushire hamwe amadosiye y’ubuvuzi canke amakarata y’ibikoresho vyashizwe mu mubiri, kandi witegure guca CPR iyo uwo muntu aguye hasi. Nusabe umuntu ariko arabibona afungure urugi rw’imbere maze akureho inzira y’aho umuntu ashobora gutwara abarwayi. Iyo uwo muntu ataco akora, agahagarika guhema nk’uko bisanzwe, nuce utangura ubwo nyene . CPR n’ugufatanya igifu ku nkubito 100 gushika ku 120 ku munota.

Igiti c'ingingo co gutoranya no gutandukanya vyihutirwa

Koresha iki kigereranyo c’ubuvuzi kugira ngo utandukanye hagati y’ugucagura kw’umutsi w’ibere, ugucagura kw’umutsi w’inda, n’ugucagura kw’umutima gusanzwe canke ugucika kw’imitsi y’umugongo mu minota ya mbere y’ingorane.

Gutahura ibintu bibiri bishobora gutuma umuntu apfa

Naho ivyo bibazo vyose bitera ukudakora neza kw’umutsi munini kuruta iyindi yose wo mu mubiri, ugucagura umutsi w’amaraso n’ugucagura umutsi w’amaraso wo mu nda (AAA)** bishika biciye mu nzira zitandukanye, bitera imiterere y’abarwayi itandukanye, kandi bisaba ingamba zitandukanye zo kuvura mu bitaro vyihutirwa.

1. Gucagura umutsi w’amaraso: Amarira y’imbere afise umuvuduko munini

Uruhome rw’umutsi w’amaraso ufise amagara meza rugizwe n’ibice bitatu bitobito cane: igihimba c’imbere gitoya cane (tunica intima), igihimba co hagati gifise imitsi myinshi (tunica media), n’igihimba c’inyuma gikomeye c’imitsi (tunica adventitia). Mu gucagura umutsi w’umutima, amarira aratera mu buryo butunguranye mu gice c’imbere c’umubiri, akenshi mu gikiriza (thoracic aorta) aho amaraso ava mu mutima ku rugero runini.

Amaraso amaze guca muri iyo marira y’imbere mu gihe c’umuvuduko w’amaraso (systolic pressure), aca agabanya (agacagura) igice co hagati c’imitsi, agacapura "false lumen" (umurongo wa kabiri, udasanzwe w’amaraso) uja hasi canke uja hejuru mu burebure bw’umutsi w’amaraso. Uko uwo muhora w’ikinyoma ugenda uratera amaraso, uratuma haba ingorane zine zishobora gutuma umuntu apfa ubwo nyene: - Guca mu musaho w’umutima (Cardiac Tamponade): Iyo iyo nkoko isubira inyuma yerekeza ku mutima ikaja mu musaho w’umutima ukikuje umutsi w’umutima, amaraso yuzuza uwo musaho agaca afata umutima gushika udashobora gupompa, bigatuma umuntu apfa bukwi na bukwi. - Acute aortic valve regurgitation: Amarira ashobora gufungura amababi y’umutsi w’amaraso, bigatuma amaraso asukira inyuma mu gitereko c’ibubamfu, agasesagura amahaha n’amazi (flash pulmonary edema). - Ugufunga umutsi w’umutima: Igipande gishobora guca mu nzira y’umutsi w’umutima w’iburyo canke w’ibubamfu, kigatuma haba umutsi w’umutima w’iburyo canke w’ibubamfu indwara y'umutima. - Ugutera nabi kw’imitsi y’amashami (Indwara y’umutima, Paraplegie, Ischemie Visceral): Uko uruzitiro rw’ikinyoma rugenda ruzunguruka rumanuka mu mutsi w’amaraso, uruzitiro rw’imbere ruvyimba rurashobora guca imitsi y’umutwe igaburira ubwonko (bigatuma ubwonko buca butera indwara y'umutima), imitsi yo munsi y’ibirenge igaburira amaboko (ituma umutsi w’ikiganza udatera neza), imitsi yo mu mugongo igaburira umutsi w’umugongo (ituma amaguru yompi aremvye bukwi na bukwi), canke imitsi yo mu mfuruka n’iy’amafyigo igaburira amara n’amafyigo.

Abaganga bashira mu migwi ibice vy’umubiri bica mu mitsi y’amaraso bakoresheje Stanford Classification System, ivyo bikaba bitegeka ko umuntu ashobora kurokoka vuba: - Stanford Type A Dissection: Birimwo umutsi w’umutima uduga (igice ca mbere kiduga kiva mu mutima) na/canke umutsi w’umutima, utitaye ku kuntu uja hasi. Ubwoko A bw’ugucapura ni ugubagwa vyihutirwa bifise urugero rw’urupfu ruduga nk’ibice 1 gushika ku 2 kw’ijana kw’isaha yose ugusanura kw’ugubagwa biracerezwa mu masaha 48 ya mbere. - Stanford Type B Dissection: Itangura mu aorta thoracique imanuka (inyuma y’umutsi w’ibubamfu wo munsi y’igihimba c’umubiri ugaburira ukuboko kw’ibubamfu) ikaja hasi yerekeza ku nda. Ubwoko B bwo gucapura bufatwa mu ntango hakoreshejwe ugucungera umuvuduko w’amaraso n’ugucungera umutima (“anti-impulse therapy”), hamwe n’ugusanura stent-graft (TEVAR) iyo ingingo zishonje amaraso canke uruhome rushobora guturika.

2. Igisebe c’umutsi w’amaraso wo mu nda (AAA): Uruhome rwacitse rwacitse intege

aneurysm ni ukwaguka (ballooning) kw’ibice vyose bitatu vy’uruhome rw’imitsi bitewe n’ugusenyuka kw’imitsi y’amaraso n’ivy’imitsi y’amaraso. Naho imitsi ishobora gutera mu gikiriza (umutsi w’amaraso wo mu gikiriza), ikunda gushika cane mu nda yo hasi munsi y’imitsi y’amafyigo (imitsi y’amaraso yo mu nda iri munsi y’amafyigo, canke AAA), aho umutsi w’amaraso usanzwe w’umuntu akuze upima nk’amasentimetero **2,0 (0,8 inci) mu gipimo. Iyo ico gice kirenze sentimetero 3,0 (inci 1,2), gisobanurwamwo ko ari umutsi w’amaraso; iyo irenze sentimetero 5,0 gushika kuri 5,5 (2,0 gushika kuri 2,2 inches), ingorane yo guca uruhome ubwayo iraduga cane.

Ivyiyumviro vyinshi vy’imitsi y’amaraso mu nda bikura bicereje mu myaka myinshi ata kimenyetso na kimwe bitera gushika bivuye mu kanya nk’ako gukubita canke bipfutse (ruptured AAA). Iyo AAA iturikiye, amaraso asuka ava mu mutsi w’amaraso aja muri kimwe mu bibanza bibiri: - Intraperitoneal Rupture y’ubuntu: Uruhome rw’imbere rw’umutsi w’amaraso ruca ruturika rukaja mu nda yuguruye. Gusohoka amaraso menshi cane mu minota mikeyi, akenshi bituma umutima uhagarara ubwo nyene imbere y’uko imodoka itwara abarwayi ishika. - Contained Retroperitoneal Rupture (The Golden Triage Window): Mu barwayi benshi barokoka igihe kirekire bihagije kugira ngo bashike mu bitaro, iyo aneurysme iratabura mu kibanza gikomeye inyuma y’inda kiri inyuma y’umwobo w’inda (hafi y’imitsi y’umugongo n’iya psoas). Ivyo bihimba bikikije n’umuvuduko w’amaraso uriko uragwa birazibira (plug) iyo nzira mu minota 30 gushika ku masaha menshi. Ariko rero, iyo umurwayi yihatira, akavyuka canke akaronka amazi menshi cane mu mutsi atuma umuvuduko w’amaraso wiwe utera cane, iyo nkoko y’inyuma y’igifu irapfuka, igahindura amaraso ashobora kurokoka akava amaraso ata co amaze.

Igereranyo ryose: Gucagura umutsi w’amaraso n’ugucagura AAA n’ugutera umutima

Kubera ko ububabare bwo mu gikiriza, mu mugongo no mu nda ari ibintu bikunze kwidodomba, abarungika abantu mu bihe vy’ivyihutirwa be n’ababibona kenshi barafata nabi ivyago vy’imitsi y’amaraso nk’indwara y’umutima, amabuye y’amafyigo canke sciatica. Suzuma iyi mbonerahamwe y'ukugereranya kugira ngo ubone ibimenyetso bitandukanya:

Ikiranga ubuvuzi Gucagura umutsi w'amaraso (ubwoko A / ubwoko B) Igisebe c'umutsi w'amaraso wo mu nda (AAA yacitse) Indwara y'umutima (Indwara y'umutima) Renal Colic (Ibuye ry'amafyigo) canke umugongo
Umuvuduko wo gutangura ububabare Instantaneous ("inkuba"): Ishika ku bushobozi burengeye 10/10 mu segonda ya mbere nyene y'intango. Bitunguranye kandi bikomeye: Gutangura bukwi na bukwi ububabare bukomeye, buhoraho mu nda, mu mugongo canke mu ruhande. Ukwiyongera buhoro buhoro: Mu bisanzwe bitangura n’ukudatekana canke guhagarika umutima bikeyi, bikaguma vyubaka mu minota 5 gushika kuri 20. Ibuye ry’amafyigo: Imiraba y’ububabare butunguranye. Ugutera umugongo: Biterwa n’uguterura canke gugobeka; iratera imbere iyo umuntu aryamye ataco akora.
Inyifato y'Ububabare Gutyaye, gutabura, gutabura, canke gutera, nk’icumu canke poker ishushe ikata imbere mu gikiriza canke mu mugongo. Ububabare bukomeye, burambiranye, butaburura, canke butera ububabare mu nda, mu mugongo wo hasi, mu rubavu, canke mu rubavu. Ugutera umukazo mwinshi, gufyonda, kwuzura, canke gujanjagura uburemere ("inzovu yicaye ku gikiriza"). Ibuye ry’amafyigo: Imiraba y’amafyigo igenda izunguruka, itera ivyatsi kuva ku ruhande gushika ku rubavu. Ugutera umugongo: Ugutera imitsi.
Aho hantu n'imishwarara Ubwoko A: Igifu c’imbere kija mw’izosi, ku rwasaya, canke ku mugongo wo hejuru. Ubwoko B: Umugongo uri hagati y’ibirenge (hagati y’ibitugu) wimukira hasi uja mu nda/amaguru. Hagati mu nda, ahantu h’uruvyaro, mu mugongo wo hasi, ku ruhande rw’ibubamfu/iburyo, canke gushika mu rubavu. Igifu co hagati canke c’ibubamfu, kikaja ku rutugu rw’ibubamfu/iburyo, ukuboko kw’imbere, izosi, urwaya, canke inda yo hejuru. Unilateral flank igera ku rubavu (ibuye), canke imitsi y’inyuma y’umugongo (strain).
Ibimenyetso vy'umuvuduko w'amaraso n'umuvuduko w'amaraso Akenshi umuntu afise umuvuduko w’amaraso mwinshi cane (\(>180/100\text{ mmHg}\)) mu ntango (canke umuvuduko w’amaraso muto iyo ari umuvuduko w’amaraso w’ubwoko A); BP y’ukuboko itangana (\(>20\ivyanditswe{ mmHg}\) itandukaniro) canke ubuze umuvuduko w’ukuboko/ukuguru. Uguhungabana kw’umuvuduko w’amaraso (BP systolic \(<90\text{ mmHg}\)), ugutera kw’umutima kwihuta, urukoba rworoshe, n’ugucika intege (syncope). BP ihinduka (isanzwe, hejuru canke hasi); imitsi y’ukuboko kw’ibubamfu n’iy’iburyo n’umuvuduko w’amaraso birangana. BP isanzwe canke irengeye gatoyi kubera ububabare; urukoba rwumye rushushe; imitsi ikomeye isanzwe mu bihimba vyose.
Ibimenyetso vy'imitsi canke vy'amaguru Kenshi: Gufatwa n’indwara y’umutima bukwi na bukwi (ugutemba mu maso, ukuboko gugoyagoya, kuvuga nabi), indwara ya Horner, canke ugukonja, gutukura, gucika intege, ukuguru kwari gusenyutse. Syncope (ugusinzira) ni ikintu gisanzwe bitewe n’ugutakaza amaraso bukwi na bukwi; umutima w’igitsina gore mu rubavu rumwe canke zompi ushobora kuba ugoyagoya canke utaboneka; amavi afise amabara y’ubururu. Ugutera umutwe canke ugusinzira birashobora kubaho, ariko ibimenyetso vy’indwara y’umutima canke ischemie y’amaguru n’amaboko ni bike cane. Nta (kiretse iyo hariho ugufatanya kw’umutsi w’umugongo; raba indwara y'amafarasi).
Isuzuma ry'inda Kenshi na kenshi birayoroshe kiretse iyo ischémie y’umutsi wa mesenterique iteye imbere. Igihimba c’inda gikomeye, giteye igomwe, gitera hejuru y’urutugu (naho bigoye kwumva ku barwayi bavyibushe cane canke bafise umuvuduko muto cane). Inda yoroshe, idafise ububabare (ishobora kugira inyiyumvo y’ukubura ibiribwa mu nda). Inda idatera; abarwaye amabuye y’amafyigo bama bagendagenda canke bazunguruka badashobora kuronka ihumure.
Imiti igabanya amaraso BIBUZWA CANE (bishobora gutuma umuntu ava amaraso mu mutima canke mu bihaha bishobora gutuma umuntu apfa). BIBUZWA CANE (vyihutisha kuva amaraso mu gitereko yica). BYEREKANWA (160 gushika kuri 325 mg ya aspirine itari mu mara itaguwe kiretse iyo umuntu afise allergie canke akava amaraso). Irinde imiti igabanya ubukana bw’indwara/aspirine gushika AAA ivuyeho ku barwayi barengeje imyaka 55.

Kumenya ibimenyetso vy'ibendera ry'umutuku mu buryo burambuye

Ibimenyetso vya kera n'ibidasanzwe vy'ugucagura kw'umutsi w'amaraso

Dukurikije amabwirizwa y’ishirahamwe mpuzamakungu ryitaho ivy’ugucagura umutsi w’amaraso (IRAD) be n’uwa ACC/AHA, abarwayi barenga 90 kw’ijana bafise ububabare butunguranye, yamara abagera kuri 30 kw’ijana mu ntango barasuzumwa nabi. Raba aya matsinda y’ubuvuzi:

  1. Ububabare butunguranye, bushobora gutabura cane: Bitandukanye n’indwara y’umutima itera buhoro buhoro mu minota myinshi, ububabare bwo gucagura umutsi w’amaraso bushika ku rwego rwo hejuru mu segonda ya mbere uko igice c’imbere mu mubiri gicagura. Abarwayi babidondora nk'aho numva "nk'aho hari ikintu cacitse mu gikiriza canje" canke "nk'aho bateye hagati y'ibitugu."
  2. Inzira y’ububabare yimuka: Uko igice c’umubiri gica kigenda kiramanuka cane mu mutsi w’amaraso (aorte) kuva mu gikiriza gushika mu nda, ububabare bushobora gutangura mu gikiriza canke mu muhogo w’imbere, bukaja hagati y’ibitugu haciye iminota 10, hanyuma bukaturika mu mugongo wo hasi canke mu bibero.
  3. "Ububabare Plus One" (Ububabare bwo mu Gikiriza/Umugongo Bufatanijwe n'Ibimenyetso vy'Imitsi canke Amaguru): Igihe cose ububabare bwo mu gikiriza canke mu mugongo buje n'ubukene bw'imitsi canke igihimba c'umubiri gikonje, wiyumvire aortic dissection mbere:
  4. Ububabare bwo mu gikiriza/umugongo + Ibimenyetso vy’indwara y’umutima: Gushika mu mitsi y’umutwe bituma umuntu agira intege nke zitunguranye ku ruhande rumwe, mu maso hakaba hacitse intege, canke akabura amajambo. (Imburi y’ibitaro ikomeye: Guha imiti igabanya amaraso mu mitsi nka tPA/tenecteplase ku murwayi w’indwara y’umutima afise indwara y’umutima iterwa n’ugucagura umutsi w’amaraso w’ubwoko A bwihishije, ni ikintu gishobora kwica abantu bose.)
  5. Ububabare bwo mu gikiriza/mu mugongo + Paraplegie (Amaguru Aremvye): Gukemura imitsi y’umugongo (na cane cane umutsi wa Adamkiewicz) bituma amaguru yompi aremvye bukwi na bukwi kandi akabura ububabare.
  6. Ububabare bwo mu gikiriza/mu mugongo + Acute Limb Ischemia: Ugufunga kw’umutsi wo munsi y’igihimba canke ukuguru gusiga ukuboko kumwe canke ukuguru gupfuye nk’umweru, gukonja nk’urubura, kutagira umutima, kandi kubabara.
  7. Painless Syncope (Ugucika intege) mu bice 5 gushika ku 10 kw’ijana: Nk’umuntu umwe ku barwayi 10 bafise ububabare bwo mu bwoko bwa A aracika intege ata bubabare buke canke ata bubabare bwo mu gikiriza buvugwa, akenshi kubera ko amaraso yasohotse mu gafuko k’umutima (cardiac tamponade) canke akacika amaraso mu gifu mu gihe gito.

Ubutatu bwa kera n'"ivyo kwiyoberanya" vy'umutsi w'amaraso wo mu nda (AAA)

Igitabo c’inyigisho ca kera c’ubutatu bw’umuntu afise AAA yamenetse gifise ububabare butunguranye bwo mu nda/mu mugongo/mu ruhande, ububabare butunguranye canke ububabare bwo mu nda, na ububabare bwo mu nda butera ubwoba. Ariko rero, inyigisho zakozwe n’ikigo c’igihugu c’Ubwongereza kijejwe ubuzima n’ukwitaho abantu (NICE) be n’ishirahamwe ry’abaganga b’imitsi (SVS) zirerekana ko ivyo bimenyetso vyose bitatu bigaragara hamwe ku barwayi ba AAA batarenga 50 kw’ijana.

  • Masquerade 2: "Sudden Sciatica or Pulled Lower Back" with Dizziness: Blood collecting against the lumbar spine and psoas muscle causes intense lower back pain radiating down the leg, paired with sweating, dizziness, or pallor when sitting up.
  • Masquerade 3: Unexplained Syncope (Fainting) with Rapid Recovery: When an aneurysm first tears into the retroperitoneum, blood pressure drops and the person faints. Once lying flat on the floor, retroperitoneal tissues temporarily tamponade the bleed so they wake up 1 to 2 minutes later feeling weak and sweaty, before the hematoma bursts completely 30 to 90 minutes later.

Who is at highest risk: genetic, medical, and lifestyle factors

Sharing risk factor history with the 911 / 112 / 999 dispatcher and emergency room triage nurse is one of the fastest ways to trigger an immediate bedside ultrasound or CT angiogram.

Risk Category High-Risk Factors for Acute Aortic Dissection High-Risk Factors for Abdominal Aortic Aneurysm (AAA)
Age and Sex Profile Occurs across a wide age range: 50 to 75 years for hypertension-driven cases, and 20 to 45 years with connective tissue disorders or pregnancy. Strongly tied to advancing age: most common in men aged 60 to 85 years and women aged 65 and older. Aneurysms in women rupture at smaller diameters.
Primary Medical Drivers Uncontrolled hypertension (high blood pressure) in over 75% of patients; bicuspid aortic valve; coarctation of the aorta; prior heart surgery. Lifetime tobacco smoking (increases AAA risk 5-fold to 7-fold); chronic hypertension; atherosclerosis; hypercholesterolemia; COPD.
Genetic & Connective Tissue Syndromes Marfan syndrome (FBN1 gene), Loeys-Dietz syndrome, Vascular Ehlers-Danlos syndrome (Type IV), Turner syndrome, and familial thoracic aneurysm. First-degree family history (having a parent, brother, or sister with an AAA quadruples a person's personal risk of developing an AAA).
Acute Physical or Chemical Triggers Sudden extreme isometric heavy lifting, cocaine or methamphetamine use, high-speed deceleration chest trauma, and late pregnancy or postpartum. Sudden severe hypertensive spikes, heavy physical straining, violent coughing fits, or blunt abdominal trauma over a pre-existing aneurysm.
Fluoroquinolone Antibiotic Warning Regulatory agencies (US FDA, European EMA, UK MHRA) warn that systemic fluoroquinolone antibiotics (ciprofloxacin, levofloxacin) double short-term risk in high-risk patients. Same fluoroquinolone collagen-degradation warning applies to patients with known abdominal aortic aneurysms.

Step-by-step first aid and pre-hospital care while waiting for EMS

When caring for someone with a suspected aortic dissection or ruptured abdominal aortic aneurysm before paramedics arrive, every action is designed to minimize aortic wall shear stress and preserve a contained clot.

Step 1: Positioning for hemodynamic stability

  • Suspected Thoracic Aortic Dissection (chest/upper back pain, often high blood pressure): Help them lie down in the position that causes the least pain and easiest breathing, usually supine (flat on the back) or semi-Fowler's (head and shoulders gently propped at a 30-degree angle). Never force a patient who is struggling to breathe to lie completely flat.
  • Suspected Ruptured AAA or signs of guhungabana (pale, cold, clammy, dizzy, faint): Lay them completely flat on their back. Do NOT elevate the legs aggressively if it causes abdominal pain, and never allow them to sit upright or stand, as sitting up drains remaining blood away from the brain and heart.
  • Unconscious or actively vomiting: Gently roll them onto their side into the lateral recovery position as a single unit (log-roll style, without twisting the torso) so vomit cannot enter the lungs.

Step 2: Do NOT palpate or press deeply on a pulsating abdomen

If you notice or suspect a throbbing mass in the middle of the person's abdomen, do not press deeply on their stomach to check it, and do not allow well-meaning bystanders to push on the belly. Deep manual pressure over a thin-walled, leaking abdominal aortic aneurysm can mechanically disrupt the fragile retroperitoneal clot and trigger immediate free rupture.

Step 3: How to perform a two-arm blood pressure and pulse check

If a digital home blood pressure monitor is nearby and using it will not delay calling emergency services or agitate the patient: 1. Measure and write down the blood pressure and heart rate on the right upper arm. 2. Immediately move the cuff to the left upper arm and measure the blood pressure there. 3. What the numbers mean: In a healthy person, systolic blood pressure between the right and left arms differs by less than \(10\text{ mmHg}\). A systolic blood pressure difference greater than \(20\text{ mmHg}\) between the right and left arms (paired with acute chest or back pain) indicates that an aortic dissection flap may be blocking one of the subclavian arteries. Report both exact numbers to the paramedics as soon as they arrive.

Step 4: Physiological calming ("Verbal Beta-Blockade")

In the hospital emergency department, the first medical treatment for an aortic dissection is intravenous beta-blockers (such as esmolol or labetalol) to drop the heart rate below \(60\text{ beats per minute}\) and systolic blood pressure between \(100\text{ and }120\text{ mmHg}\), reducing the pounding force of each heartbeat against the torn aortic wall. At home, before IV medications arrive, panic and pain are the enemy: - Clear frightened crowds out of the room and coach the patient to take slow, gentle breaths, strictly avoiding holding their breath or bearing down (avoid the Valsalva maneuver, which spikes aortic pressure). - Keep the environment quiet and reassure them that help is minutes away.

1. Why paramedics practice "Permissive Hypotension" in Ruptured AAA

In most medical emergencies involving low blood pressure, paramedics infuse large bags of intravenous saline rapidly to bring blood pressure back up to \(120/80\text{ mmHg}\). In a ruptured abdominal aortic aneurysm or bleeding aortic dissection, giving large volumes of IV fluid to normalize blood pressure before the surgeon clamps the aorta is dangerous. - Raising systolic blood pressure above \(90\text{ to }100\text{ mmHg}\) with saline dilutes natural clotting factors, cools the blood, and hydraulically blows off the temporary clot ("popping the clot") that is keeping the patient alive. - Ku bw’ivyo, amabwirizwa mpuzamakungu (NICE NG156 mu Bwongereza, Sosiyete y’abaganga b’imitsi muri Leta Zunze Ubumwe za Amerika, n’Ishirahamwe ry’i Buraya ry’abaganga b’imitsi) ategeka abaganga gukora ugutera umuvuduko w’amaraso mu buryo bwemewe: igihe cose umurwayi ariko aravyuka, ariko aravuga, kandi akaguma afise umuvuduko w’amaraso wo mu bwoko bwa systolic to{7\(xt\}te mmHg}\)**, amazi arabujijwe mu gihe imodoka itwara abarwayi igenda ijana mu cumba co kubagiramwo imitsi.

2. Why hospital bypass to an Aortic Center saves lives

Not every local hospital has a cardiothoracic surgeon (for Type A aortic dissection) or a vascular surgeon with an endovascular hybrid operating suite (for ruptured AAA) on call 24 hours a day. When you clearly state "Suspected Aortic Dissection" or "Known Abdominal Aortic Aneurysm with Sudden Pain and Syncope" during your initial emergency call, regional EMS systems can activate a Direct-to-OR "Code Rupture" or "Code Aorta" pathway, bypassing smaller clinics to take the patient straight to a surgical center.

Exact communication script for 911 / 112 / 999 and hospital triage

When speaking to an emergency dispatcher or triage nurse, use this specific clinical language:

  • For Suspected Aortic Dissection:

    "I need an emergency ambulance at [Exact Address]. The patient is a [Age]-year-old [male/female] who developed instantaneous, 10-out-of-10 tearing [chest / upper back] pain at [Time]. [He/She] also has [a blood pressure difference of X mmHg between the right and left arms / sudden leg weakness / Marfan syndrome / a bicuspid aortic valve]. We suspect an Acute Aortic Dissection. We have NOT given aspirin."

  • For Suspected Ruptured AAA:

    "I need an emergency ambulance at [Exact Address]. The patient is a [Age]-year-old [male/female] with [a known Abdominal Aortic Aneurysm / a history of smoking and hypertension] who suddenly developed severe [abdominal / lower back / flank] pain and [fainted / is pale, sweaty, and dizzy]. We suspect a Ruptured Abdominal Aortic Aneurysm. We are keeping [him/her] lying flat and still."

Triage preparation checklist while the ambulance is en route

  • Exact time of pain onset written down: Surgeons need to know the exact minute the tearing pain or fainting occurred.
  • Both arm blood pressures recorded (if measured): Write down Right Arm BP and Left Arm BP on a piece of paper.
  • Prior aortic imaging or surgical cards located: Grab any discharge summary showing previous aneurysm size (e.g., "4.8 cm infrarenal AAA"), stent-graft implant cards, or heart valve cards.
  • Complete list of blood thinners identified: Immediately tell paramedics if the patient takes warfarin, apixaban, rivaroxaban, dabigatran, edoxaban, clopidogrel, or daily aspirin, so the hospital can prepare emergency reversal agents (such as 4-factor prothrombin complex concentrate [PCC], idarucizumab, or andexanet alfa) before surgery.
  • Nothing by mouth confirmed: Tell paramedics the time of the patient's last meal or drink for safe anesthesia planning.

Prevention and screening: Catching aneurysms before they rupture

Because an intact aortic aneurysm can be repaired electively with a 95 to 98 percent survival rate, whereas a ruptured aneurysm carries a mortality rate of 70 to 80 percent, ultrasound screening and blood pressure management are life-saving:

  1. One-Time Abdominal Ultrasound Screening:
  2. In the United States (USPSTF & SVS Guidelines): A one-time abdominal ultrasound is recommended for all men aged 65 to 75 who have ever smoked, and selectively for men and women aged 65 to 75 with a first-degree family history of an AAA.
  3. In the United Kingdom (NHS AAA Screening Programme): All men are invited for a free ultrasound screening during the year they turn 65, and anyone over 65 who has not been screened can self-refer.
  4. Genetic and Echocardiographic Screening for Thoracic Aneurysms:
  5. First-degree relatives (parents, siblings, and children) of anyone who suffers an acute thoracic aortic dissection or has a bicuspid aortic valve should undergo genetic counseling and baseline echocardiography or CT/MR angiography to measure their aortic root diameter.
  6. Daily Lifestyle Protection for Known Aneurysm Patients:
  7. Stop smoking completely (cuts the rate of aneurysm expansion in half) and keep resting blood pressure below \(130/80\text{ mmHg}\).
  8. Avoid maximal Valsalva straining: People with known aortic aneurysms should avoid heavy isometric weightlifting (where you hold your breath and strain near maximum capacity), which can spike intra-aortic blood pressure above \(300\text{ mmHg}\). Moderate aerobic exercise is generally encouraged; verify specific weight limits with a vascular specialist.

Taking a certified hands-on first aid and CPR course from the Red Cross, the American Heart Association, St John Ambulance, or a local emergency training provider gives you the practical skills to recognize circulatory shock, manage an unconscious airway, and perform high-quality chest compressions while paramedics are on the way.

Ibibazo bikunda kubazwa

A heart attack is caused by a blood clot blocking a coronary artery, so chewing aspirin stops that clot from growing. In contrast, an aortic dissection or ruptured aneurysm is a mechanical tear in the wall of the aorta; giving aspirin disables platelets, prevents protective clot formation, and causes fatal bleeding into the chest, abdomen, or pericardial sac.

How can I tell the difference between a ruptured abdominal aortic aneurysm and a kidney stone in an older adult?

Both can cause sudden one-sided flank pain radiating into the groin because retroperitoneal blood irritates the same nerves and ureter as a stone. However, any adult over age 55 (especially a smoker or hypertensive) who develops first-time kidney stone pain with dizziness, pale clammy skin, fainting, or low blood pressure must be treated as a ruptured aortic aneurysm until an ultrasound or CT scan rules it out.

What does a blood pressure difference between the left and right arms mean during chest pain?

In a healthy adult, systolic blood pressure between the right and left arms differs by less than 10 millimeters of mercury (mmHg). If someone with sudden severe chest or back pain has a systolic blood pressure difference greater than 20 mmHg between their arms (or a weak wrist pulse on one side), an acute aortic dissection flap is likely blocking the subclavian artery supplying that arm.

If a person with sudden back or abdominal pain faints and then wakes up feeling much better on the floor, is the emergency over?
