Yintoni iCerebral Infarction?

Inkcazo yeCerebral Infarction

I-Cerebral infarction ikwabizwa ngokuba yi-ischemic stroke.Esi sifo sibangelwa yimimandla eyahlukeneyo yokuphazamiseka konikezelo lwegazi kwizicubu zobuchopho, okukhokelela kwi-ischemia ye-cerebral kunye ne-anoxia necrosis, kwaye ke intsilelo yeklinikhi yemithambo-luvo.

Ngokutsho kwe-pathogenesis eyahlukeneyo, i-cerebral infarction ihlukaniswe kwiindidi eziphambili ezifana ne-cerebral thrombosis, i-cerebral embolism kunye ne-lacunar infarction.Phakathi kwabo, i-cerebral thrombosis yolona hlobo luqhelekileyo lwe-cerebral infarction, i-akhawunti malunga ne-60% yazo zonke i-cerebral infarction, ngoko ke oko kuthiwa "i-cerebral infarction" ibhekisela kwi-cerebral thrombosis.

Yintoni iPathogeny yeCerebral Infarction?

1. I-Arteriosclerosis: i-thrombus yenziwe ngesiseko se-atherosclerotic plaque eludongeni lomthambo.
2. I-Cardiogenic cerebral thrombosis: Izigulane ezine-fibrillation ye-atrial zivame ukwenza i-thrombosis, kwaye i-thrombus igeleza kwingqondo ukuze ithintele imithwalo yegazi ye-cerebral, ebangela i-cerebral infarction.
3. Izinto ezikhusela umzimba: Ukungakhuseleki okungaqhelekanga kubangela i-arteritis.
4. Izifo ezithathelwanayo: i-leptospirosis, isifo sephepha, kunye ne-syphilis, enokubangela lula ukudumba kwemithambo yegazi, ekhokelela kwi-cerebral infarction.
5. Izifo zegazi: i-polycythemia, i-thrombocytosis, i-coagulation ye-intravascular coagulation, njl njl.
6. Ukungahambi kakuhle kokuphuhliswa kokuzalwa: i-dysplasia ye-muscle fibers.
7. Ukulimala kunye nokuphuka kwe-intima yomkhumbi wegazi, ukwenzela ukuba igazi lingene eludongeni lwegazi kwaye lenze umjelo omncinci.
8. Abanye: iziyobisi, i-tumors, i-fat emboli, i-gas emboli, njl.

Ziziphi iimpawu zeCerebral Infarction?

1. Iimpawu eziphambili:intloko ebuhlungu, isiyezi, i-vertigo, isicaphucaphu, ukugabha, imoto kunye/okanye i-sensory aphasia kunye ne-coma.
2. Iimpawu ze-Cerebral nerve:amehlo ajonge kwicala le-lesion, ukukhubazeka kwe-neurofacial kunye nokukhubazeka kweelwimi, ukukhubazeka kwe-pseudobulbar, kuquka ukuminxa ngenxa yokusela kunye nobunzima bokugwinya.
3. Iimpawu zomzimba:i-hemiplegia yelungu okanye i-mild hemiplegia, ukunciphisa ukuvakalelwa komzimba, ukuhamba ngokungazinzanga, ubuthathaka belungu, ukungakwazi ukuzibamba, njl.
4. I-edema ye-cerebral enzima, ukunyuka koxinzelelo lwe-intracranial, kunye ne-cerebral hernias kunye ne-coma.I-vertebral-basilar artery system embolism ihlala ikhokelela kwi-coma, kwaye kwezinye iimeko, ukuwohloka kunokwenzeka emva kokuzinza kunye nokuphuculwa, kwaye kukho ukuphindaphinda kwe-infarction okanye i-hemorrhage yesibini.
