Ukuphazamiseka kubangelwa ukuphazamiseka kwegazi okanye ukuphuma kumbilini. Ezinye izibetho zithintela inxalenye enkulu yengqondo , kanti ezinye zichaphazela ummandla omncinci . Ingaba i-stroke echaphazela ngokuthe ngqo inxalenye enkulu okanye encinci yengqondo ixhomeke kakhulu ekubeni ingaba isitya esikhulu segazi okanye isitya segazi esincinci.
Kukho imivumba emikhulu kwaye kukho iinqwelo ezincinane-kwaye zihluke kakhulu.
Iimitha zeBriin
Yonke inxalenye yomzimba, kuquka ubuchopho, ineemithambo kunye neemvini. Iimitha ze-Arteries zizisa igazi kwingqondo, ngelixa iimbilini zithwala igazi. Iingqungquthela ze-carotid zinemibhobho emikhulu ekhohlo kunye nekhohlo lekhohlo entanyeni. Umzobo ngamnye we-carotidi uhlula kwaye uphawule njengoko uphakamisa intamo entanyeni. Amagatya nganye komnatha we-carotidi ahlula kwiingqungquthela ezinkulu ezi-3 ezinika igazi kwingqondo. Ezi zi-6 eziyintloko zomthambo ezondla ingqondo ngesiphumo se-oksijini esinezityebi kunye nezondlo ziyi-artery ze-cerebral arteries, i-right and left-left berebral arteries kunye ne-right and left left post-artery cerebral arteries. Le mibhobho emikhulu iyahlukana ibe ngamasebe amancinane namancinci njengoko ihamba kuyo yonke ingqondo.
Yiyiphi i-Stroke enkulu?
Isibetho esikhulu senqanawa yinto ephazamisayo eyenzekayo ngenxa yokuphazamiseka kokuhamba kwegazi kwelinye leemibhobho emikhulu engqondweni.
Ngenxa yokuba i-stroke enkulu inqanawa eyenzekayo xa i-artery enkulu ivaliwe, onke amagatsha awo amancinci nawo ayavalwa. Ngoko inqanawa enkulu yesikhephe esonakalisa inxalenye enkulu yengqondo, ebizwa ngokuba 'yintsimi yendawo' yeso sixhobo esikhulu segazi.
Iimbangela zeentsimbi ezinkulu
Ininzi yexesha, iinqanawa ezinkulu zezimbiza zibangelwa iingubo zegazi ezihamba ukusuka kwenye indawo emzimbeni kwaye zifake ngaphakathi kwintsimbi engqondweni.
Lawa maqhekeza egazi ngokuqhelekileyo avela entliziyweni, kodwa unokuhamba ukusuka kwinqanaba le- carotid okanye kwinqanawa elikude kwenye indawo emzimbeni.
I-clot yegazi eyenza ngaphakathi kwinqanawa yegazi ibizwa ngokuba yi-thrombus, ngelixa i-clot yegazi ihamba. Ininzi enkulu yeenqanawa ezinkulu zezibetho, zichaza ukuba zibangelwa ngamacangca egazi ukusuka kwenye indawo emzimbeni.
I-embolus (i-clot yegazi ehambahambayo) ngokuqhelekileyo isenokubanjelwa kwisiteyiti esele sinezixhobo ezingonakaliyo. Ingxowa yangaphakathi yeetriyeri ingaba yingozi kwaye ibonakaliswe ngenxa yengozi yomshukela ophezulu, i-cholesterol yegazi ephakamileyo, amanqanaba aphezulu eoli kunye ne-triglycerides, ukutshaya kunye nesifo sikashukela. Izinto zokuphila, ngakumbi ukusetyenziswa kweziyobisi, uxinzelelo kunye nokudakumba, kunokunceda nelo hlobo lomonakalo, olubizwa ngokuba yi-vascular disease.
Ngamanye amaxesha, inqanawa enkulu inokuphuhlisa imboleko engaphakathi enobungozi, apho i-thrombus inokuthi ifake kwisitya esikhulu. Kulezi zihlandlo ezingavamile, i-stroke enkulu yesikhephe isifo sobhubhane.
Yintoni Eyenzekayo Xa Ufumana Umtya Omkhulu Wokhuseleko?
Ngenxa yokuba imithambo emikhulu engqondweni ihlinzekela indawo enkulu yengqondo, iinqanawa ezinkulu zikhulu kakhulu.
Imivimbo emikhulu ingabangela ukukhubazeka okukhulu kwegazi ngenxa yokulimaza inxalenye ebalulekileyo yengqondo, ukuphazamisa inani lexhoba lomzimba lomzimba kunye nengqondo.
Izibetho ezinkulu zivame ukudala ukuvuvukala engqondweni, oko kungenza unxepheko lube yingozi ngakumbi kwixesha elifutshane kwaye lunokunciphisa ukubuyiswa.
Yintoni enokuyilindela emva kokukhwabanisa kweMpahla enkulu
Isibilini somsondo we-cerebral isinye sezona zixhaphakileyo ezinkulu. Kwiyona nto ininzi, iintsuku ezimbalwa zokuqala emva kwesithintelo esikhulu senqanawa. Ukubuyiselwa ngokuqhelekileyo kuphuculwa kwaye kulungiswa ngokuqhelekileyo kubaluleke kakhulu emva kokuba kuqhutywe iinqanawa ezinkulu.
Ukubuyiswa kwesigxina kwexesha elide kubandakanya ukulawulwa kwezinto ezinobungozi be-stroke ezifana nesifo sengxinzelelo kunye nesifo senhliziyo. Inxalenye ephambili yokubuyiswa kwesifo kukwabandakanya ukuthintela iingxaki ezinxulumene ne-stroke .
Ukuya phambili
Ukuba wena okanye othandekayo uye wahlaselwa yintsimbi enkulu, unokufuna ukulungelelanisa indlela yokuphila eguqula imiphumo yesifo sakho, njenge-hemiplegia, ubunzima bomzimba , iingxaki zokunxibelelana, iingxaki zokunxibelelana kwendawo , iingxaki zesibindi kunye nokugwinya ingxaki . Fumana okunye malunga naloo apha .
