Kuthetha ukuthini ukuba unesikebhe esincinci?
Ukuphazamiseka kwengqondo yingozi yokuchophazwa kwengqondo ebangelwa ukuphazamiseka kwegazi kummandla wengqondo. Iimitha ze-arriethisa i-oksigen enegazi elityebileyo kwingqondo. Ngenxa yendlela indlela i-arriyo ehlelwe ngayo, iirriyiti ezinkulu zingena kwingqondo kwaye zahlula, zixhuma zibe yimibhobho emancinci kunye encinci kunye ne-capillaries ukubonelela iindawo ezikufutshane zeengqondo ngegazi le-oxygen.
Ukuba i-artery enkulu iyavalwa, yonke isebe evela kuloo mto mkhulu ihluleka ukuhambisa igazi elifanelekileyo kwingqondo, kwaye umphumo kuthiwa yi-stroke enkulu. Ukuba isebe elincinci lombhobho liyavalelwa, ke i-stroke encinane yomkhumbi ibonakala, iwonakalisa ummandla omncinci wengqondo .
Yintoni into encinci yesikhephe?
I-stroke encinci yesikhephe isithintelo ekuphumeni kwegazi kwindawo encinci yengqondo. I-Arrivithi yesebe ibe ngama-capillaries amancinci ahambisa i-oksijeni igazi elityebile kwingingqi encinane kakhulu yengqondo. I-stroke encinci yesikhephe esenzakalisa inxalenye yengqondo eyenziwe ngumkhumbi omncinci wegazi, odla ngokubizwa ngokuba yintsimi ye-vascular ye-artery encinci.
Kutheni kubakho iinqanawa ezincinane?
Kukho isibalo sezizathu ezincinane zokubetha kweenqanawa. I-artery encinci ingaba yinto engavumelekanga ngaphakathi, kwaye ngoko ke iyakwazi ukuthatha i-cholesterol enamathele kunye neengcambu zegazi njengoko igazi liphuma.
Xa iifom ze-clot zingaphakathi kwinqanawa yegazi, ingavimbela ukuhamba kwegazi, loo ngqayi ibizwa ngokuba yi-thrombus.
Kodwa ukuba i-clot yegazi ifomnye kwenye indawo emzimbeni, ngokuqhelekileyo entliziyweni okanye emthonjeni we-carotid, inokudiliza kwaye ihambe kwenye imithambo yegazi, ekugqibeleni ifake kwi-artery encinci engqondweni ukuze ibangele isifo.
Olu hlobo lwegazi lokuhamba ngegazi libizwa ngokuba yi-embolus.
Imithambo yegazi ewonakaliswe engqondweni isetyenziselwa ukudala iingubo zegazi kunye nokuxaka i-blood clots. Xa ezininzi iimithambo zegazi zigule, le meko ibhekiswa njengesifo se-vascular. Xa imithwalo yegazi emininzi ebuchosheni isifo, loo nto ibizwa ngokuba yi- cerebrovascular disease .
Yintoni Ebangelwa Izifo Ze-Cerebrovascular Disease?
Imithambo encinci yegazi iqhutywe ngaphakathi ngaphakathi ngenxa yexesha elide lokungabikho kwiimeko ezilimaza ingxube yangaphakathi. Le miqathango ibandakanya isifo senhliziyo, isifo sikashukela, umfutho wegazi ophezulu, kunye ne-cholesterol yegazi ephakamileyo kunye ne-triglyceride (uhlobo oluthile lomnxeba), uxinzelelo kunye neengxube (eziqhelekileyo zivela kwi-cigarettes) emzimbeni.
Ngethamsanqa, izifo zesifo se-cerebrovascular kunye nezinye izinto ezinobungozi be-stroke zibuyiselwa.
Yintoni eyenzekayo xa umntu efumana ulwaphulo oluncinane lwesitya?
I-stroke encinci yesitya ingaba mnene, kodwa inokuba yinto enzulu. I-stroke encinci yesikhephe iyakwenzeka nantoni na engqondweni.
- Izibilini ze-Brainstem ezincinci : Izibetho ezincinci ezichaphazela i-brainstem zingabonakalisa, kuba i-brainstem iyindawo encinane elawula imisebenzi ebalulekileyo. Izibetho zeBrainstem ziquka ukubetha kwe- midbrain, ukubetha kwe- pontine , kunye nokubethelwa kwemilingo njenge- Wallenberg's syndrome .
- Iinqwelo ezincinci Izibonda: I -stroke encinci iyakhathaza imimandla engaphandle yengqondo, edla ngokufumana igazi kwiimitha ezininzi zegazi. 'Ukuxhamla' kwigazi kunomphumo wokukhusela owenza iinqanawa ezincinci zesiphumo esincinci. Abanye banokuze bangabonakali ngokupheleleyo. I-stroke engabonakaliyo ibizwa ngokuba yi- stroke . Ingxaki yokuba neentlobo ezininzi zecala kukuba ekugqibeleni 'ukukhuphela' ukuphindaphindwa kwegazi kunokuphazamiseka, kubangela iimpawu eziphawuleza ezivela kwinqanaba elincinci lomkhumbi- 'umsila owawuqhekeza iinkamela.' Oku kungakhokelela kwingxaki ebizwa ngokuba yi- vascular dementia , eyona uhlobo lomqondo wokugula ngengqondo ohlukile kwi-Alzheimer's disease. Iziphumo ze-Vascular dementia ngenxa yokuba neenqanawa ezincinci kwiinqanawa.
- Iinqwelo ezincinci Izibetho ezincinci : I- stroke encinci, echaphazela imimandla ejulile yengqondo, ingabangela iimpawu ezinzulu ezifana nokulahlekelwa kwintlungu okanye ubuthathaka, kodwa ngokuqhelekileyo akuyiyo ingozi yokuphila.
Ukuya phambili
Ngaphandle kokuba ulwaphulo lwenqanawa lwenqanawa yintlungu yesifo sengqondo, yinto engumqondiso wokulumkisa kunokuba imeko yengozi. Uninzi lwabantu luya kubuyiselwa ngempumelelo, kwaye abanye baqhubeka befumana iinyanga eziphindaleleyo emva kokunciphisa intsimbi encinci. Nangona kunjalo, i-stroke encinci yesikhephe ibaluleke ngokwaneleyo ukuba iqinisekise ukuba utshintsho olunzulu lokuziphatha luquka ukulawulwa ngokugwenxa kwimiba yakho yengozi. Ukubetha kungabulala okanye kukukhubaza. Ukuthintela olunye uhlangothi kungongeza kwi-12 1/2 iminyaka ebomini bakho ! Isibetho esincinci sesitya sithetha ukuba lixesha lokuzithobela ukukhuselwa kwesifo soqhawulo.
