Kwezinso azalwa naso. malformation arteriovenous

Arteriovenous malformation - plexus is crimped nezitsha mncane-ngodonga, okuyinto oluchazayo emithanjeni yegazi. Lesi simo esiyingqayizivele sibangelwa singenzeka kunoma iyiphi ingxenye yomzimba wakho. Nokho, ingozi enkulu malformation imithambo ingqondo.

Imbangela ukuthuthukiswa isimo is hhayi kusungulwa. malformation Arteriovenous, cishe has a imvelo zenani elikhulu eziyifa kanye ubhekwa yesifo azalwa naso. Ngakho, abaphethwe yilesi sifo, ingozi yesifo kakhulu phakathi kwezihlobo. Ochwepheshe baye bathola ezinye ukuthi banesibopho nokukhula okuvamile imithambo yegazi ezakhini zofuzo lapho ukuguquka kwezakhi zofuzo kungabangela ukuqala ukwelukwa. Ngaphezu kwalokho, syndromes yathola ukuthi, ngaphandle lesi sifo zihlanganisa iziyaluyalu imisebenzi yezinye kwezitho izinhlelo, kanye ukuhlukumeza isakhiwo sabo.

Ngenxa yokwanda koshintsho sofuzo abathintekayo ukuthuthukiswa kanye nokukhula lamaseli semithambo ukushintsha yabo obumba, kumaseli ethile endothelial abami ezindongeni kwangaphakathi. Ngenxa yalokho, i-capillary inethiwekhi evamile ukuthi unesibopho exchange of imikhiqizo umzimba, amagesi nezakhi hhayi kwakhiwa. Lokhu kuholela yokuthi endaweni iseli esemgwaqweni i malformation arteriovenous, kodwa nokho anamukeli, lemali edingekile umoya-mpilo bese izinto ezifanele. Ngakho, ukusebenza kwabo kuyaphazamiseka.

Giant malformation arteriovenous kuphakamisa nokwehlisa kwegazi ezizungezile. into enjalo kwezokwelapha ithole igama "ukuntshontsha mkhuba". Encishisiwe liningi igazi kwenzeka ngenxa outflow yegazi e sokugembula.

Ngaphezu kwalokho, e-isakhiwo uhlelo lwemithambo evamile, capillary kanye emithambo yegazi ingcindezi iconsi kwenzeka kancane kancane kusuka imithambo ukuze emithanjeni. Endabeni le aluka lilondolozwe okusezingeni eliphezulu ngokwanele. Ngoba isakhiwo emithambo yegazi ayivumeli ukudluliswa umfutho ophakeme kangaka, kukhona kungenzeka ukopha futhi kumiswa ukwa.

Lapho kunokubhanqanisa indawo eningi ebuchosheni, i angagcina ukopha subarachnoid, ukopha ebuchosheni into noma ventricles. Ezimweni ezinjalo, isimo ngokuvamile nzima ngenxa yokwanda ingcindezi intracranial kubangelwa kuvalwe izindlela outflow ngoba cerebrospinal fluid, iziyaluyalu ezihlukahlukene izinzwa cranial.

Ngokuvamile izimpawu aluka incike indawo yayo kanye nosayizi.

malformation semithambo has a isici sici - ikhanda. Lokujabulela kungaba efana migraine, abe pulsed futhi eyodwa emaceleni.

Kwezinye izimo, bangase ukuthuthukisa nokuquleka. Nge semali malformation angase ukubonisa izimpawu cerebral liningi igazi ngesimo ukukhubazeka.

Uma iziguli subarachnoid ukopha uzizwa ubuhlungu bekhanda nesiyezi, kanye retching, ukuhlanza. Kwezinye izimo, iziguli ulahlekelwe ukwazi, ukuwela equlekile. Kukhona uhlangothi imilenze, izandla, angaboni kahle, Gait, inkulumo, nokungakwazi afeze ukunyakaza okunenjongo. Ezimweni ezingavamile kakhulu, lapho ubukhulu elincane ukopha, isimo kukhona asymptomatic.

Indlela eyinhloko ekwelapheni sokugembula aluka semithambo kuyinto ukuhlinzwa. Kulokhu, zikhona izindlela eziningana wokusebenza.

Phakathi kokungenela zomphakathi wenza craniotomy nokususwa okuphelele malformation. Endovascular ipayipi indlela kuhilela esasikhipha ensimini egunjini lokuhlolwa kwezifo. Khona-ke, usebenzisa iziqukathi ekhethekile eyenziwa ukugqagqana okuphakelayo kunokubhanqanisa Umthambo. Lapho kukhiqizwa radiosurgery ngemisebe olulodwa endaweni sokugembula, okuyinto kuholela ekubhujisweni imithambo ezishintshwe.
