Iyini I-Cerebral Infarction?

Incazelo ye-Cerebral Infarction

I-cerebral infarction ibizwa nangokuthi i-ischemic stroke.Lesi sifo sibangelwa ukuphazamiseka okuhlukahlukene kokunikezwa kwegazi ezicubu zobuchopho, okuholela ku-cerebral ischemia kanye ne-anoxia necrosis, bese kuba nokushoda kwemizwa yomtholampilo okuhambisanayo.

Ngokusho kwe-pathogenesis ehlukene, i-cerebral infarction ihlukaniswe ngezinhlobo eziyinhloko ezifana ne-cerebral thrombosis, i-cerebral embolism kanye ne-lacunar infarction.Phakathi kwazo, i-cerebral thrombosis iwuhlobo oluvame kakhulu lwe-cerebral infarction, olubalelwa ku-60% yazo zonke i-cerebral infarction, ngakho-ke okuthiwa "i-cerebral infarction" ibhekisela ku-cerebral thrombosis.

Iyini i-Pathogeny ye-Cerebral Infarction?

1. I-Arteriosclerosis: i-thrombus yakhiwa ngesisekelo se-atherosclerotic plaque odongeni lwe-arterial.
2. I-Cardiogenic cerebral thrombosis: Iziguli ezine-atrial fibrillation zithambekele ekwenzeni i-thrombosis, futhi i-thrombus igelezela ebuchosheni ukuze ivimbe imithambo yegazi yobuchopho, ibangele ukuqhuma kwe-cerebral infarction.
3. Izici zokuzivikela komzimba: Ukuzivikela okungavamile kubangela i-arteritis.
4. Izici ezithathelwanayo: i-leptospirosis, isifo sofuba, nogcunsula, okungase kubangele kalula ukuvuvukala kwemithambo yegazi, okuholela ku-cerebral infarction.
5. Izifo zegazi: i-polycythemia, i-thrombocytosis, i-coagulation esakazwayo ye-intravascular, njll.
6. Ukungajwayelekile kokuthuthukiswa kokuzalwa: i-dysplasia ye-muscle fibers.
7. Ukulimala nokuphuka kwe-intima yomkhumbi wegazi, ukuze igazi lingene odongeni lwegazi futhi lenze umzila omncane.
8. Abanye: izidakamizwa, izimila, i-fat emboli, i-gas emboli, njll.

Yiziphi Izimpawu Ze-Cerebral Infarction?

1. Izimpawu eziyinhloko:ikhanda, isiyezi, i-vertigo, isicanucanu, ukuhlanza, i-motor kanye/noma i-sensory aphasia ngisho ne-coma.
2. Izimpawu ze-Cerebral nerve:amehlo abheke ohlangothini lwezilonda, ukukhubazeka kwe-neurofacial nokukhubazeka kolimi, ukukhubazeka kwe-pseudobulbar, okuhlanganisa ukuminyanisa ngenxa yokuphuza kanye nobunzima bokugwinya.
3. Izimpawu zomzimba:I-hemiplegia yesitho noma i-hemiplegia ethambile, ukuzwa komzimba okunciphile, ukuhamba okungaqinile, ubuthakathaka bezitho, ukungakwazi ukuzithiba, njll.
4. I-cerebral edema enzima, ukwanda kwengcindezi ye-intracranial, ngisho ne-cerebral hernias kanye ne-coma.I-vertebral-basilar artery system embolism ivame ukuholela ku-coma, futhi kwezinye izimo, ukuwohloka kungase kwenzeke ngemva kokuzinza nokuthuthukiswa, futhi maningi amathuba okuphindaphinda kwe-infarction noma ukopha kwesibili.
