E fetang ischemic tlhaselo

E fetang ischemic tlhaselo, hangata ntshetsa pele ka tšohanyetso e bua ka ditlhaelo efe kapa efe tsepamiso regressed feletseng ka lihora tse ka tlaase ho mashome a mabeli a metso e mene. tlhaloso ena e fapana bophara le tse fapa-fapaneng tsa matšoao. Re lokela ho hlokomela hore boemo ba ka hase kamehla ho bakoa ke ischemia. Mohlala, migraine kapa lefu tsoeroe ke sethoathoa tsamaea le liponahatso tsepamiso methapo ea kutlo. Pholosang matšoao ischaemia fetang hora e 'ngoe ka' na a bontša hore sebakeng se itseng ea boko dinama tse nyenyane tse infarction undergone.

Itseng liponahatso boemo e bontša hore tsamaiso e amehang ka karolo pathological eo e fuoa mali ka tsela e mothapo itseng (bohareng bokong, carotid, 'me tse ling).

E fetang ischemic tlhaselo e na le mekgwa pathophysiological. Ka 'nete ena e bontsha stereotypical tlhaho, nako le maqhubu a ya mananeo iphetang.

Ka mohlala, nako e nako (metsotso e leshome le metso e mehlano kapa ka tlaase), khafetsa (makhetlo a mahlano ho tse leshome ka letsatsi), mofuta o mong oa sethoathoa bofokoli ka letsohong le tsohle kapa letsohong le ho ba teng (kapa ba sieo) ya mafu a puo a ka bontša hore motho narrowing proximal kapa occlusion ya methapo ya, a tsamaea khaello ka phepelo peeletso ea mali. boemo Sena se etsa hore ischemia tsepamiso ka cortex ea fapaneng le ea Lefatše. Leha ho le joalo, ka hlakoreng le leng, ketsahalo e 'ngoe ea boloetse ba puo le bofokoli ka letsoho kapa wrist lihoreng tsa leshome le metso e e hlokometse ka phallo tlaase ea mali ka lebaka la ho embolism. Hammoho mohlomong ena eaba ba etsa le infarct sebakeng ka setseng tse tobileng lobe.

Hlobaetsang ischemic setorouku ka letamo e mong oa methapo tse fatang maikutlo e etsa hore tsoelo-pele ea lethopa, eseng feteng disentimitara ngoe. boemong bona e denoted e le transiently-lacunar tlhaselo ischemic. Eme tsamaisong basilar-vertebral, tabeng ea hore na ba ne ba ka lebaka la distal (omimvo) kapa proximal basilar mothapo stenosis ka vertebrates, ka kakaretso o ile a bontša a louoa dizzy, dysarthria le Pono habeli.

Kahoo, e fetang ischemic tlhaselo halefisoa ke lintho tse peli: embolism le marotholi tsepamiso tsa phepelo ea mali. Tabeng ea pele, profinseng ea mochine o totobetse. Ka tekanyo e monyenyane a ithuta ketsahalo Tia semelo sa ea moo phokotseho ea phepelo ea mali bokong. Ka kgonego tsohle, fokotsa inflow ka lebaka la ho ea bohlokoa stenosis kapa occlusion tsa tsela e itseng tse mahlonoko. Le ea bohlokoa haholo ke ho hloka peeletso phallo ea mali ho sebakeng ischemia. Ho phaella moo, ho ke ke ho hlokahala hore ho nahana ka elasticity ea sejana se lerako, e tiileng e qamathelang mali le lintho tse ling. E fetang ischemic tlhaselo ka mefuta joalo ho nkoa e le ea 'nete, ke hore, e le mananeo a ho li sa embolic hlahang ho yona.

State khutlelang ho feletseng. Leha ho le joalo, ponahalo ea tsona e ke temoso mabapi le monyetla oa setorouku nakong e tlang. Kahoo, mekgwa pathophysiological ea linaha tsena tse peli e lokela ho nkoa e le 'moho. Re lokela ho hlokomela hore ngaka e sa khone ho fana ka tlhokomelo ea bakuli le e fetang tlhaselo ischemic, a sa tsebe le lisosa tsa eona.
