Mibvunzo inowanzo bvunzwa¶

Chii chinonzi "Danger Triangle yeChiso," uye nei kusvina bundu ipapo kuchikonzera kugwamba kweropa rehuropi?¶

Iyo "Danger Triangle yeChiso" inzvimbo ine katatu inomhanya kubva pabhiriji remhino yako ichidzika kuruboshwe nekurudyi makona emuromo wako, kusanganisira mhino yako, mhino, uye wekumusoro muromo. Kusiyana netsinga dziri mumuviri wako wese dzine mavharuvhu enzira imwe chete kuti ropa rirambe richiyerera rakananga kumwoyo wako chete, tsinga yekumeso (angular vein) uye tsinga dzemaziso dzepamusoro nedzikaderera dzakatenderedza maziso ako dzine zero valves. Kana ukadzvinya kana kuputika mvura yakadzika kana pimple (inowanzo batwa neStaphylococcus aureus) mukati memhino kana muromo wepamusoro, kuzvimba kwakakomberedza kunovhara mvura inodzika yakadzika, uye kudzvinya kunosundira ropa rine utachiona uye bhakitiriya kumashure kuburikidza netsinga dzeziso zvakananga mu cavernous sinus pazasi pehuropi.

Sei kusakwanisa kutendeudzira ziso rimwe kunze ("chitanhatu-nerve palsy") chiratidzo chekutanga chekunyevera checavernous sinus thrombosis?¶

Mitsinga mishanu yekranial inopfuura nepacavernous sinus painoenda kuziso nechiso: Cranial Nerves III, IV, V1, uye V2 yakachengetedzwa zvakachengeteka mukati memadziro ekunze ane fibrous ekunze kwe sinus, nepo Cranial Nerve VI (iyo abducens nerve, iyo inodzora mhasuru inotenderedza mboni yeziso rako kunze kwakananga nepakati nepakati pemvura yemukati yenzeve isina kutenderera) carotid artery. Kana mabhakitiriya nemagwamba eropa anotanga kupinda mucavernous sinus, Cranial Nerve VI ndiyo tsinga yekutanga yakashambidzwa mupus nekumanikidza. Murwere ane utachiona hwe sinus kana kumota kumeso obva atanga kuona kaviri kaviri nekuti ziso rimwe harigone kubuda kunze rinoda emergency MRI/MRV uye IV mishonga inorwisa mabhakitiriya pakarepo.

Vanachiremba vanotaura sei musiyano pakati pe orbital cellulitis uye cavernous sinus thrombosis?¶

Kunyange zvazvo zvose zviri zviviri zvinogona kukonzera ziso rakatsvuka, rakazvimba, rinoputika (proptosis), fivha, uye kurwadza kana kurambidzwa kufamba kweziso, zviratidzo zvitatu zvinonongedza zvakananga kune cavernous sinus thrombosis: (1) Kupararira kweBilateral: nokuti sinuses yekuruboshwe neyokurudyi yakabatana nechepakati nepakati nepakati nepakati nepakati, kuzvimba uye kuoma kweziso kusvetuka kusvika pakatarisana ne48 maawa ekutanga; (2) Trigeminal nerve numbness: kupinza kana kugunzva zvishoma pahuma yemurwere (CN V1) kana dama repamusoro (CN V2) rinoratidza kupera kana kurasikirwa kwekorneal blink reflex; uye (3) Muchetura wetsinga wakanyanya, unosanganisira kurwadza kwemusoro kuseri kwemaziso, kuoma mutsipa, mwana akarembera/ane usimbe, uye kufamba kwemaziso kwakaoma nechando zvisingaenderane nekuzvimba kwemaziso.

Chii chaizvo chiri #1 chinokonzera septic cavernous sinus thrombosis nhasi kana isiri kusvina mapundu?¶

Pasati pawanikwa mishonga inorwisa mabhakitiriya, kudzvinya mamota kumeso nemhino ("furuncles") mukati meDanger Triangle ndiko kwainyanya kukonzera kukonzera kwecavernous sinus thrombosis. Nhasi, kunyange zvazvo mamota emumhino achiri kukonzera 15 kusvika 25 muzana yezviitiko, # 1 chikonzero chemazuva ano (chinokonzera 50 kusvika 60 muzana yezviitiko) ndeye acute bacterial sphenoid sinusitis uye ethmoid sinusitis. Nekuda kwekuti sphenoid sinus inogara kuseri kwemhino yakaparadzaniswa necavernous sinus nemadziro ane bony asingasviki 0.5 millimeters akaonda (anowanzo kuve neakasikwa microscopic gaps), iyo isina kurapwa yakadzika sinus hutachiona inogona kunyura yakananga mukati mecavernous sinus.

Sei vanachiremba vachipa mishonga yeropa (Heparin) yevhavha ine utachiona mukati me cavernous sinus?¶

Pakutanga kuona, kupa ropa rakapfava panguva yehutachiona kunonzwika kune ngozi, ndicho chikonzero vanachiremba vanotanga kuita CT uye MRI scan kuti vaone kuti hapana uropi hunobuda ropa. Kana kubuda ropa kwabviswa, intravenous unfractionated heparin (kana kuti yakaderera-molecular-weight heparin) pamwe chete nepamusoro-dose intravenous antibiotics inoita basa rinokosha rokuponesa hupenyu: inomisa ropa re septic kuti ripararire kupararira mukati memakumbo emukati mune rimwe ziso remurwere kana kudzokera kune imwe nzvimbo yeuropi ye venous sinuses, inodzivirira kubuda kweropa uye kuvharidzira sinuses. inochengeta tsinga dzakavhurika kuitira kuti mishonga inorwisa mabhakitiriya ipinde muutachiona.

Chii chandinofanira kuita kana ndine ronda rinorwadza mukati memhino yangu kana pamuromo wangu wepamusoro izvozvi?¶

Chekutanga, isa maoko ako pairi: usambosvina, tsikirira, nhonga, kana kupuruzira netsono. Isa jira rakachena, rinodziya, rakanyorova zvinyoro nyoro uchirwisa nzvimbo yacho kwemaminetsi gumi nemashanu katatu kana kana pazuva kuti ukurudzire kubuda kwekunze kwekunze pasina kumanikidzwa. Ona chiremba zuva rimwe chete remishonga inonzi topical mupirocin (2%) nasal mafuta uye mishonga inorwisa mabhakitiriya inovhara Staphylococcus aureus (uye MRSA kana yakawanda munharaunda yako). Kana ukaita chero fever, kupararira kutsvuka kukona yeziso remukati mako, kutemwa nemusoro kuseri kwemaziso ako, kuzvimba kweziso, kana kuona kaviri, enda kudhipatimendi rekuchipatara.
