Ukwehla kwesifo sofuba kwemikhumbi ye-cerebral yisifo esibi esiholela ekubuyeni kancane kancane kwesimiso sezinzwa zomphakathi, ingozi yokudala ukuphazamiseka kwengqondo nokushaywa yisifo. Kulezi zifo, izitshalo ezingenakudliwa kanye ne-extracranial ezondla ubuchopho ziyathinteka.
Kwenzekani nge-atherosclerosis yezikebhe ze-cerebral?
Lesi sifo siqala ngeqiniso lokuthi izindonga ze-arteries zihlanganiswe ne-cholesterol. I-cholesterol yinto enamandla equkethe igazi, okunye okuqukethwe okudingekayo emsebenzini obalulekile ojwayelekile womzimba. Kodwa-ke, ukwanda kokugxilwa kwawo egazini nasezindlini ezinjengamabala angenayo i-insoluble ezindongeni ze-arteries kungukuqala kwenqubo ye-atherosclerotic.
Bese uqala ukwakha amaphuzu okuthiwa i-atherosclerotic plaques. Le nqubo yenziwa ngezigaba ezintathu:
- Isiteji samafutha, amaqabunga - ukufakwa kwegobolondo langaphakathi lwezindonga ze-lipids.
- I-Liposclerosis - ukwakheka emkhakheni wamafutha ama-tissue ezixhunyiwe kanye nokwakhiwa kwe-plaque. Ingqimba ye-plaque ingaba nesifo se-ulcerate, ukuphahlazeka, ukuchoboza i-fibrin nama-platelet. Kusukela kulesi sikhala kungasusa izingxenye ezincane, okuthi, ngokugeleza kwegazi, zingene ezingeni ezincane zobuchopho bese zivale.
- I-Atherocalcinosis - ukufakwa kwe-calcium usawoti (i-lime) nokuhlanganiswa kwe-plaque. I-plaque iyakhula kancane kancane futhi ingawuvala ngokuphelele isibani somkhumbi.
Ngenxa yokwakheka kwamacwecwe, ukunikezwa kwegazi kwehla, izingxenye zobuchopho zilahlekelwa yi-oxygen nezinto eziwusizo. Uma imithwalo yegazi ibonakala ebuchosheni, ama-necrotic, ama-cysts nezibazi ezifakwe emathisini ebuchopho. Ngenxa yokwehliswa kwamangqamuzana omzimba, umsebenzi ovamile wengqondo uphazamiseka.
Izimbangela ze-artery of the artery of atherosclerosis
Ukuphefumula kwamathambo we-cerebral arteries (i-cerebral, i-trunk) ivela ngenxa yokuphulwa emzimbeni we-fat metabolism. Izici eziyingozi kule sifo ziyi:
- ukubhema;
- ukuphathwa kabi kotshwala;
- indlela yokuphila yokuhlala;
- ukukhuluphala;
- isifo sikashukela mellitus;
- i-hyperlipidemia;
- ukucindezeleka komzimba;
- i-coagulability eyengeziwe yegazi;
- ukucindezeleka;
- iminyaka ekhulile.
Izimpawu zokuphefumula kwe-artery cerebral artery
Izimpawu zokuphefumula kwesifo sofuba ze-cerebral vessels zihluke kakhulu, futhi akuzona zonke ezingabonakalisa ngokushesha. Lezi zibonakaliso zemitholampilo ezilandelayo ziyisici:
- ikhanda lokukhwabanisa okukhulu nobude;
- isiyezi;
- umsindo ezindlebeni ;
- ukuphazamiseka kokulala (ubunzima bokulala, ukuvuka ebusuku ebusuku, ukulala, ukulala phakathi nosuku);
- ukhathala okwandisiwe, kunciphisa amandla okusebenza;
- imemori enciphile;
- ukuhlukumezeka kwezici zobuntu;
- ukukhathazeka ngokweqile, ukusola;
- ukungabi nokusebenzisana;
- inkulumo engacacile, njll.
Njengomthetho, okokuqala isiguli esinesifo sofuba sibhekene nezibonakaliso ngezikhathi ezithile ezibonakalayo, sizihlanganisa ngokukhathala, ukuvezwa isikhathi eside endaweni engenawo umoya, njll. Lokhu ikakhulukazi isiyezi, inhloko, umsindo ngaphakathi
Ukuqhubeka kwalesi sifo kubangela ukuvela kwesiteji sokukhokha imali, lapho umuntu engakwazi khona ukwenza ngaphandle kosizo olungaphandle. Imemori namakhono okucabanga ziwohloka kakhulu, ubunzima bokuzimela buvela. Ngalesi simo, ingozi yokushaywa yisifo sikhukhula, eyenzeka ngenxa yokuphela kokuphela kwegazi ngenxa yokukhishwa kwesitsha nge-plaque atherosclerotic.
