Aneurysm yeenqanawa zesiberebhu

I-Aneurysm yeenqwelo ze-cerebral yimeko ye-pathological ebonakaliswe ukuphulwa kweempahla kunye nokwandiswa kwiindonga zokwandiswa ngendlela yesigxoba. Njengomthetho, imbangela yesifo yintlupheko yesifo sokuzalwa okanye isifo esingenakunzima. Ngokuqhelekileyo, ukuvela kwayo kubangelwa yintlungu okanye i-atherosclerosis.

Kule meko, ukuphulwa kungafumaneka kwiindawo ezahlukeneyo ze-cerebral vasculature. Nangona kunjalo, njengommiselo, basesiseko salo kwinqanaba le- Willis.

Ngokuxhomekeke kuhlobo lokuphuhliswa, ukuphazamiseka kwemibandela kunye neengxaki zengxabano kubonakala.

I-aneurysm ye-Arteriovenous yeenqwelo ze-cerebral ifakwe ngoluhlobo lwesitya seenqwelo ezinobulunga. Olu hlobo lwesifo lubangelwa ukusetyenziselwa ukuxhumana ngokuthe ngqo kwegazi phakathi komnatha kunye nesisu somzimba. Kuyaziwa ukuba uxinzelelo lwegazi luphezulu kakhulu kunengcinezelo yentsholongwane. Ukunxibelelana ngokukhawuleza phakathi kwezi nqanawa kubangela ukukhutshwa kwegazi kwi-artery kwi-vein, ngokugqithisa izicubu zeengqondo. Kule meko, i-ejection ihambelana noxinzelelo oluphezulu. Oku kubangele ukwandiswa kweendonga ezinobomvu. I-aneurysm yeenqwelo ze-cerebral yenziwe. Iimpawu zokukhulisa ziquka intlungu enzima, ukunyakaza nokukhathazeka, ukuxhwala. Ngenxa yongcinezelo olwandayo ngaphakathi kwandiswa kunye nokucuthwa kweendonga, ukwanda kwe-saccular resulting. Oku, kubangelwa ukuphuma kwamanzi, okusoloko kuphelela ekufeni.

I-aneurysm ye-arterial yeenqwelo ze-cerebral ivela kwimibhobho kwaye ingaba enye okanye ininzi, ingabalulekanga kwaye inkulu kakhulu. Ngokuxhomekeka kohlobo lokuvuza, ukuphazamiseka kuhambelana nemibonakalo eyahlukeneyo. Ukungaqhelekanga okungaqhelekanga kungafunyanwa ngethuba. I-aneurysm engabonakaliyo ibonakaliswa yimvakalelo yokunyanzeliswa kwemisipha yengqondo kunye nengqondo, isifo esiyintloko esingapheliyo. Ukongezelela, eso sifo sihambelana nokuphulwa kombono nombono, ukuxhamla, ukuphulwa kobuzwe besikhumba kunye nesimo sombuso.

Igalelo lokunyusa likhokelela ekuphumeni kwegazi kwangaphakathi. Ukuphuka kwe-Aneurysm ehamba kunye nokuphuma kwamanzi kunokuphindaphindiwe. Ngelo xesha, kufuneka kuphawulwe ukuba kwimeko yokuqala, izinga lokufa lenzeke kwi-10 ukuya kwi-30 ekhulwini, kwaye ngokuphindaphinda ngokuphindaphindiweyo, izinga lokufa lidlula kuma-70 ekhulwini.

Ukuphumelela kwizenzo zokuxilonga kulungile ekukhokeni kwedatha ngokuphuma kwegazi (okanye isiqhelo sakhe). Kwezinye iimeko, akunakwenzeka ukuseka ukuxilongwa ngokuchanekileyo kwe-Aneurysm ngesiseko sempawu. Ukucaciswa kwe-diagnostic kwenziwa ngokusebenzisa i-angiography. Ukuxilongwa kwemithambo yegazi yengqondo ingabonisa ukuba khona kwandiswa, ubukhulu bayo kunye nendawo. Ezinye izinto ezongezelelweyo (ezongezelelweyo) zikhomputha (CT) kunye ne- magnetic resonance (MRI) tomography.

Aneurysm yeenqanawa zesiberebhu. Unyango.

Ukuqinisekiswa kokuxilongwa kwenkqubo yokwandiswa kwindlela ecacileyo yokutyunjwa kwonyango ngendlela yokungenelela. Kwezinye iimeko, umsebenzi awunqunyelwe ukuba i-aneurysm ifinyelele kwisayizi esongela ubomi yesigulane. Umsebenzi ungenziwa ngeendlela ezahlukeneyo. Kwezinye iimeko, ukwandiswa kutyinwe ngesikhewu esikhethekileyo kwaye kunqunyulwa, ngoko ke, kwisitya apho sakha khona. Oku kuphelisa umngcipheko wokuphuka nokuphuma kwamanzi. Kwesinye imeko, indawo echaphazelekayo isuswe kwaye ithathelwe indawo yi-prosthesis okanye ngokufakela isifuba esikhethekileyo sayo (stent).
