Cerebral ischemia: ua, cov tsos mob, kev kho mob

Cerebral ischemia - ib tug ua txhaum ntawm cov ntshav txaus rau tej qhov chaw ntawm lub paj hlwb thiab thoob plaws hauv lub cev raws li ib tug tag nrho. Yog li nrog cov ntshav nyob rau hauv nws yog tsis ruaj khov txaus ntawm oxygen thiab as-ham tsim nyog rau kom zoo lag luam. Tom qab, cov pa deprivation yuav ua tau kom mob stroke, disturbance ntawm lub paj hlwb, txoj kev tuag ntawm nws cov ntaub so ntswg, ua dysmotility, tuag tes tuag taw, tsis muaj peev xwm xav tias, hais lus.

Cov ua rau cerebral ischemia

Lub ntsiab ua ischemia nyob rau hauv cov neeg laus nyob rau hauv lub ntiaj teb no niaj hnub no yog atherosclerosis ntawm cov hlab ntsha ntawm lub paj hlwb. Fatty deposits uas noog rau lub puab phab ntsa ntawm lub nkoj qab thus, maj txhaws nws thiab thaiv ntshav txaus. Lwm heev ua yuav ua tau ib tug overlap ntawm cov ntshav khiav tsis zoo hauv cerebral cov hlab ntsha los ntawm cov ntshav txhaws (thrombi).

Cerebral ischemia yuav tshwm sim vim vasospasm ntawm kev nyuaj siab (ntshai, mob), raws li ib tug tshwm sim ntawm lub cev poob plig los sis tus ntawm tsawg kub, nyob rau hauv tus ntawm tshuaj lom tshuaj. Tshwj xeeb tshaj yog noteworthy pab ntau heev thiab feem ntau siv los ntawm tus txiv neej cov tshuaj toxins nyob rau hauv luam yeeb haus luam yeeb (tus ntse vasospasm tshwm sim), thiab haus dej haus cawv haus dej haus cawv (thrombi tsim nyob rau hauv cov ntshav, uas sib tshooj microcapillaries thiab feeb meej ntshav).

Cov tsos mob ntawm cerebral ischemia

Tus thawj cov tsos mob ntawm cerebral ischemia manifested nyob rau hauv lub yuav txo tau ntawm cov xim, nco puas, qaug zog thiab ntxaug ntawm poob siab system. Ntev li tshee excitability, causeless txob taus, mus ob peb vas swings kuj txhais tau hais tias ib tug neeg muaj cerebral ischemia. Cov tsos mob ntawm coronary artery kab mob ntawm lub paj hlwb tshwm sim mus pw tsaug zog thaum hmo ntuj, uas yog ua ntiav thiab nyob tsis tswm.

Sudden mob taub hau, ntshav siab dauv, kiv taub hau, tsaus muag, impaired kev sib koom tes, piav thoob hlo kabmob mob, kev hais lus thiab tsis pom kev - yog tseem ntxwv tej yam tshwm sim hais tias ib tug neeg yog cov neeg kawm txoj cerebral ischemia.

Cerebral ischemia kev kho mob

Nyob rau hauv niaj hnub mob xyaum yog ob tug loj kev kho mob ntawm ischemic lub hlwb tus kab mob: kho mob thiab kev phais. Thaum noj tshuaj ischemia raws li kev txais tos ntawm cov tshuaj uas kov cov ntshav txaus thiab ntxiv dag zog rau cov hlab ntsha phab ntsa.

Thaum phais hlwb ischemia kho operative tshem thrombus los yog atherosclerotic cov quav hniav los ntawm cov ntshav txog ntsha thiab es ntshav khiav los ntawm puas hlab ntsha los ntawm lawv cov reconstruction thiab prosthesis.

Ib tug ntawm cov newer txoj kev es cov ntshav mov rau ib tug tshwj xeeb kev kho mob ntawm ischemia qia hlwb, uas, tom qab ib tug muab ob npaug rau koom haum saib xyuas mus rau hauv lub plawv system tsim tshiab collateral hlab ntsha network compensating tiav me nyuam ntawm cov pa thiab as-ham rau lub puas cheeb tsam, raws li zoo raws li siv hlab ntsha qub thickness thiab elasticity, tshem tawm txhaws, kho hlwb puas hlwb cov ntaub so ntswg.

Nyob rau hauv tas li ntawd, nyob rau hauv cov kev kho mob ntawm cerebral ischemia thiab mob stroke kev tiv thaiv nyob rau physiotherapy cov txheej txheem tswj kev tsim tej yam kev mob rau txoj kev loj hlob ntawm ib tug network ntawm collateral hlab ntsha uas haum rau lub paj hlwb, bypassing cov neeg muaj mob thiab puas cov hlab ntsha. Yuav kom txo tau cov mob heev ntawm mob ischemia xwm tshuaj rau kev siv ntawm analgesic tshuaj.

Cerebral ischemia - ib cov yeeb ncuab ntawm tib neeg noj qab haus huv. Yog li ntawd, rau kev tiv thaiv ntawm ischemia yog tsim nyog los ntawm ib tug heev thaum ntxov muaj hnub nyoog los tiv thaiv lawv tus kheej los ntawm lub ntsiab yam tseem ceeb ntawm nws cov tsos: tshem tawm los ntawm nws cov zaub mov ntawv qhia zaub mov, nplua nuj nyob rau hauv roj, tsis haus luam yeeb thiab tsis tau sim ib tug luam yeeb, tsis txhob phem quav dej caw, tsis txhob stressful lub sijhawm thiab txaus siab rau lub neej.
