Mere nwee ischemic ọrịa strok

Na atrial fibrillation, na myocardial infarction, na prosthetic obi valves, endocarditis nje uwa embolus anya nke-emechi arịa lumen na-eduga ná ischemic ụbụrụ anụ ahụ. Mgbe obere arịa occlusion na myocardial infarction, ọrịa shuga, na ọbara mgbali elu nwere ike kpụrụ nke recessed òkè nke necrosis na ụbụrụ. Ya mere, unu na-etolite ọtụtụ ebe nke ischemic mmebi nke ụbụrụ ammamihe na nta abdominal, kpọ lacunar ọrịa strok. Ọtụtụ mgbe, ihe mgbaàmà nke a n'ụdị ọrịa ehichapu ya.

Nke a bụ nnọọ oké ọrịa - Ischemic ọrịa strok, ihe mere nke nwere ike chịkọtara dị ka ndị a:

• The thrombus ma ọ bụ ihe e dere ede na-apụ si mgbidi ahụ na site na ọbara abatakwa obere arịa nke ụbụrụ.
• Blood clot etịbede efep endocardial na-emechi lumen nke ụbụrụ akwara.
• Bụrụ na nke mebiri hemodynamics, obi odida na ogbenye nrugharị ihe embolus si n'obi adaghị carotid akwara.
• Lacunar ụbụrụ ischemia na a ndabere nke ọbara mgbali na-arịa ọrịa shuga mellitus oké.
• Ime na a trauma akwara nwere ike ukwu, nke na-eduga ọrịa ụbụrụ ischemia.

Ischemic strok nwere atọ degrees nke ntaramahụhụ. Igbunye ụbụrụ mgbaàmà na Baịbụl hiwere isi n'ebe. Isi ọwụwa, mgbu na eyeballs, nke enwekwu na ha ije, ọgbụgbọ, dizziness na vomiting ọsọ mgbaàmà.

Mmetụta ya na-adabere ọrịa afọ, ebe orunótu nke vaskụla occlusion, oge nke occlusion nke collaterals na ọbara mgbali. The oge agafeela kemgbe mkpọchi na ukwuu ebe mmeri, na kpu abịa irreversible Filiks. Ịrịba ama nke ischemic strok adabere na orunótu nke occlusion. Mgbe occlusion nke ihu ụbụrụ akwara na-emetụta ala ụkwụ, ịzụlite oké ike, paresis ma ọ bụ mkpọnwụ, mkpọchị okwu.

Na mmeri nke posterior ụbụrụ akwara e a mebiri nke cerebellum ọrụ nke ụbụrụ azuokokoosisi, occipital na temporal lobes. E nwere ihe isi ike na-elo, akụkụ okuku ume na ịda mbà n'obi, na oké njọ imebi nke obi. O nwere ike ịbụ na-esogbu na nchikota nke mmegharị, uche na ihe mgbu na okpomọkụ. Ihe kwesịrị ịrịba ama stupor nke nsụhọ ruo Coma, skewing ihu dị ka a n'ihi nke mmeri nke trigeminal na ọdịdị ihu akwara mkpọnwụ ọkara ahụ. Na akụkụ nke na-emepe emepe nystagmus, strabismus.

Ischemic ọrịa strok na occlusion n'etiti ụbụrụ akwara e ji sensory disturbances na mkpọnwụ na-abụghị n'akụkụ nke lesion. Nsogbu n'obi uche, amalite paresis ele ihe anya, nke mgbago aka na ụkwụ na ihu.

Mgbe carotid akwara thromboembolism amalite paresis n'akụkụ nke ọzọ gafere na tụlee sharply ọhụụ na n'akụkụ nke occlusion.

Mgbe basilar akwara occlusion Ischemic strok nwere ike gosi na ụzọ dị iche iche, dabere na larịị nke lesion. Ma eleghị anya, tinnitus na-anụ ọnwụ ruo ya ọnwụ, nystagmus na dizziness, vomiting na ọgbụgbọ. Na mmeri na ogwe nke ebe basilar akwara ma ọ bụ vertebral akwara pụrụ hụrụ zuru mkpọnwụ, abụọ-kwadoro paresis anya na amaghị onwe ya.

Usoro ischemia nke ụbụrụ anụ ahụ bụ reversible n'ime 6-12 awa. Mgbe ụfọdụ, mgbe i nwere ike ịgụ na ụbọchị. Ya mere, ọ dị mkpa ka kwesịrị ekwesị na-na a-adọ ha n'ụzọ na-enye ndị dị mkpa nlekọta na-enwe ndidi, ma ọ bụrụ na e nwere onye na ischemic ọrịa strok. Nye ya udo, nụ obi na akpa ume, na-emefu mgbochi nke nsogbu. Ọ dị mkpa iji weghachi ọbara, ụbụrụ nchedo site n'ihu mmebi, na nkwado nke ya nkịtị nri.
