Chii chinonzi Cerebral Infarction?

Tsanangudzo yeCerebral Infarction

Cerebral infarction inonziwo ischemic stroke.Chirwere ichi chinokonzerwa neakasiyana edunhu ropa rekupa kusagadzikana muuropi tishu, zvichiita kuti cerebral ischemia uye anoxia necrosis, uye ipapo rinoenderana kiriniki chetsinga deficit.

Maererano nemhando dzakasiyana dzepathogenesis, cerebral infarction yakakamurwa kuva mhando huru dzakadai secerebral thrombosis, cerebral embolism uye lacunar infarction.Pakati pavo, cerebral thrombosis ndiyo yakajairika mhando yecerebral infarction, inoverengera inenge 60% yezvese cerebral infarction, saka iyo inonzi "cerebral infarction" inoreva cerebral thrombosis.

Chii chinonzi Pathogeny yeCerebral Infarction?

1. Arteriosclerosis: thrombus inoumbwa pahwaro hwe atherosclerotic plaque mu arterial wall.
2. Cardiogenic cerebral thrombosis: Varwere vane atrial fibrillation vanowanzoita thrombosis, uye thrombus inoyerera ichipinda muuropi kuvhara tsinga dzeropa, zvichiita kuti cerebral infarction.
3. Zvirwere zvinodzivirira zvirwere: Kusagadzikana kwemuviri kunokonzera arteritis.
4. Zvikonzero zvinotapukira: leptospirosis, tuberculosis, uye syphilis, izvo zvinogona kukonzera kuputika kwemidziyo yeropa nyore nyore, zvichiita kuti cerebral infarction.
5. Zvirwere zveropa: polycythemia, thrombocytosis, kuparadzira intravascular coagulation, nezvimwewo zvinowanzoitika kune thrombosis.
6. Congenital developmental abnormalities: dysplasia yemhasuru fibers.
7. Kukuvadza uye kuputika kwe intima yemudziyo weropa, kuitira kuti ropa ripinde mumadziro emadziro eropa uye rigadzire nzira yakamanikana.
8. Vamwe: zvinodhaka, mapundu, mafuta emboli, gas emboli, nezvimwewo.

Ndezvipi Zviratidzo zveCerebral Infarction?

1. Subjective zviratidzo:musoro, dzungu, vertigo, kusvotwa, kurutsa, motokari uye/kana kunzwa aphasia uye kunyange pakoma.
2. Cerebral nerve zviratidzo:maziso anotarisa kudivi rekukuvadza, neurofacial paralysis uye lingual paralysis, pseudobulbar paralysis, kusanganisira kudzipwa kubva pakunwa uye kunetseka pakumedza.
3. Zviratidzo zvemuviri:Limb hemiplegia kana mild hemiplegia, kuderera kwekunzwa kwemuviri, kufamba kusina kugadzikana, kushaya simba kwemakumbo, kusagadzikana, nezvimwewo.
4. Yakanyanya cerebral edema, yakawedzera intracranial pressure, uye kunyange cerebral hernias uye coma.vertebral-basilar artery system embolism inowanzoita kuti pave pakoma, uye mune dzimwe nguva, kuora kunogona kuitika mushure mekugadzikana uye kuvandudzwa, uye pane mukana mukuru wekudzoka kwe infarction kana yechipiri kubuda ropa.
