He aha ka Cerebral Infarction?

Ka Wehewehe o ka Cerebral Infarction

Ua kapa ʻia ʻo Cerebral infarction i ka ischemic stroke.Hoʻokumu ʻia kēia maʻi ma muli o nā maʻi hoʻolako koko āpau i loko o ka ʻiʻo o ka lolo, e alakaʻi ana i ka cerebral ischemia a me ka anoxia necrosis, a laila ka deficit neurological clinical.

Wahi a nā pathogenesis like ʻole, ua māhele ʻia ka cerebral infarction i nā ʻano nui e like me ka cerebral thrombosis, cerebral embolism a me ka lacunar infarction.I waena o lākou, ʻo ka cerebral thrombosis ka ʻano maʻamau o ka cerebral infarction, e helu ana ma kahi o 60% o nā maʻi cerebral a pau, no laila ka mea i kapa ʻia ʻo "cerebral infarction" e pili ana i ka cerebral thrombosis.

He aha ke ʻano o ka maʻi o ka cerebral infarction?

1. Arteriosclerosis: ua hoʻokumu ʻia ka thrombus ma ke kumu o ka atherosclerotic plaque ma ka paia arterial.
2. Cardiogenic cerebral thrombosis: ʻO ka poʻe maʻi me ka atrial fibrillation hiki ke hana i ka thrombosis, a kahe ka thrombus i loko o ka lolo e ālai i nā kīʻaha koko cerebral, e hoʻopiʻi ai i ka cerebral infarction.
3. ʻO nā mea pale: ʻO ka pale ʻole ke kumu o ka arteritis.
4. Nā mea maʻi maʻi: leptospirosis, tuberculosis, a me syphilis, hiki ke hoʻoulu maʻalahi i ka mumū o nā kīʻaha koko, e alakaʻi ana i ka infarction cerebral.
5. Nā maʻi koko: polycythemia, thrombocytosis, disseminated intravascular coagulation, etc.
6. Nā mea ʻino o ka ulu ʻana o ka hānau ʻana: dysplasia o nā ʻiʻo ʻiʻo.
7. ʻO ka pōʻino a me ka haki ʻana o ka intima o ke kīʻaha koko, i komo ke koko i ka paia o ke kīʻaha koko a hana i kahi ala haiki.
8. ʻO nā mea'ē aʻe: nā lāʻau lapaʻau, nā maʻi koko, ka momona momona, ke kinoea emboli, a pēlā aku.

He aha nā hōʻailona o ka Cerebral Infarction?

1. Nā hōʻailona kumuhana:ʻo ke poʻo, ʻūlū, vertigo, nausea, luaʻi, kaʻa a/a i ʻole sensory aphasia a me ka coma.
2. Nā hōʻailona o ke aʻalolo cerebral:Nānā nā maka i ka ʻaoʻao lesion, neurofacial paralysis a me lingual paralysis, pseudobulbar paralysis, me ka ʻoki ʻana i ka inu ʻana a me ka paʻakikī i ka ʻai ʻana.
3. Nā hōʻailona kino:limb hemiplegia a i ʻole hemiplegia haʻahaʻa, hoʻemi ʻia ke ʻano o ke kino, ka hele ʻole ʻana, nāwaliwali o nā lālā, incontinence, etc.
4. ʻO ka edema cerebral koʻikoʻi, hoʻonui i ke kaomi intracranial, a hiki i ka cerebral hernias a me ka coma.ʻO ka vertebral-basilar artery system embolism e alakaʻi pinepine ai i ka coma, a i kekahi mau hihia, hiki ke hōʻino ʻia ma hope o ka paʻa ʻana a hoʻomaikaʻi ʻia, a nui ka hiki ke hoʻi hou i ka infarction a i ʻole ka lua koko koko.
