Aneurysms cerebral

Useshonile izitsha cerebral iyisimo sokugembula libhekene ukwephulwa kwesakhiwo imithambo ukwakha ezindongeni zabo njengoba izandiso isikhwama. Ngokuvamile, imbangela isifo ukuphazamiseka azalwa naso noma okungavamile kwesakhiwo. Akuvamile waphawula ivela khona ngenxa ukuhlukumezeka noma isifo sokuqina kwemithambo yegazi.

kungenzeka Ngesikhathi ukwephulwa okufanayo elise ezingxenyeni ezahlukene inethiwekhi ubuchopho semithambo. Nokho, njengoba umthetho, ukuthi akuphi phansi yayo endaweni kwesiyingi Willis.

Kuye uhlobo ukuthuthukiswa ababonakali ngezikhundla futhi arteriovenous igazi sifo.

Arteriovenous useshonile cerebrovascular umelwe ikhoyili enwetshiwe izitsha emithambo yegazi. Lolu hlobo ukwephulwa kubangelwa ukusungulwa ukuxhumana okuqondile phakathi igazi umthambo, Umthambo nogwali. Kuyaziwa ukuthi ingcindezi igazi kuphakame kakhulu kunalokho emithambo yegazi. Ukuxhumana okuqondile phakathi izitsha kuholela ejection kwegazi kusukela Umthambo ku vein, ngokudlula nezicubu ingqondo. Lapho lokhu kukhululwa kuhambisana umfutho ophakeme. Lokhu kubangela ukunwetshwa odongeni emithambo yegazi. Izindlela aneurysms palsy. Izimpawu kumiswa izandiso zihlanganisa ubuhlungu kakhulu, ukunyakaza iziyaluyalu lobukhali nokuquleka. Ngenxa yalokho kwanda khona ingcindezi ngaphakathi ukuwathuthukisa ehlambulula izindonga ezakhiwe sacciform isandiso idabukile. Lokhu, kubangela intracranial ukopha, okuyinto ngokuvamile sigcina ngokuba ukufa.

aneurysms Arterial imithambo cerebral kwenzeka imithambo futhi kungase kube eyodwa noma amaningi, ezincane nezinkulu kakhulu. Kuye uhlobo ukugeleza kuhambisana ezahlukene ukubonakaliswa ukuhlukumeza. disorder Asymptomatic bungabonakala ithuba. aneurysms Unruptured wabonakaliswa imizwa zlib we izinzwa cranial nobuchopho, ikhanda ezingamahlalakhona. Ngaphezu kwalokho, lesi sifo kuhambisana ukuhlukumeza yokuhogela nokuthinta umbono, nokuquleka, ukwephula ukuzwela kwesikhumba futhi isimo sobuso.

Isandiso igebe kuholela ukopha zangaphakathi. Useshonile ukudabuka ephelezelwa ukopha, kungase kuphinde kushiwo abanye. Kufanele kuqashelwe ukuthi esimweni nokufa lokuqala kwenzeka eziyishumi ukuze amathathu amaphesenti, futhi ngesikhathi sekhefu okuphindaphindiwe - nokufa rate kuka amaphesenti ayisikhombisa.

Kuphethe izinyathelo zokuxilonga kuyasiza uma kukhona ulwazi ukopha intracranial (isiqephu yakhe). Kwezinye izimo, ngesisekelo izimpawu ukusungula uphethwe ngqo akunakwenzeka useshonile. Ukucaciswa ukuxilongwe kusetshenziswa angiography. Ucwaningo zokuxilonga izitsha ubuchopho wembula khona wokwanda, usayizi waso kanye nendawo. Njengoba ezinye (ezengeziwe) izinyathelo kwikhompyutha (CT) kanye resonance kazibuthe (MR) imaging.

aneurysms Cerebral. Ukwelashwa.

Ukuqinisekiswa sitholakele imfundo ukunwetshwa kuyinkomba oqondile for ekwelapheni kokungenela kuhlinzwa. Kwezinye izimo, ukuhlinzwa aluboniswa kuze kube ngomzuzu lapho isifo sokuvuvukala kwemithambo ifinyelela osayizi nesineke ezisongela ukuphila. Ukusebenza kungaba kwenziwe ngezindlela ezihlukahlukene. Kwezinye izimo ezikhethekile, isandiso isiqeshana aboshezelwa futhi inqanyuliwe kanjalo kusukela isitsha kwakhiwa kuyo. Lokhu kungabi sengxenyeni ingozi ukudabuka ukopha. Kwelinye icala, ukususwa ingxenye abathintekayo Kwenziwa futhi esikhundleni sako ulethe wokufakelwa noma ukufaka Uhlaka esikhethekile ke (stent).
