Ukuphazamiseka komonakalo kwengqondo kubonakala ngenxa yokuphazamiseka kwegazi kwiindawo ezithile zobuchopho. Oku kwenzeka njengesiphumo sokukhutshwa kwesitya segazi okanye ukuphuma kweesitya segazi kwingqondo. I-stroke idla ngokubizwa ngegama elenzakaliswe kwengqondo okanye ngesitya segazi esivinjiweyo. Isibilini esisisiseko se-cerebral (MCA) sisinye sezibethe ezinkulu ezinkulu.
Iyintoni i-Stroke ye-Artery Cerebral Stroke?
Ukuphazamiseka kwe-MCA kukuphazamiseka kokuhamba kwegazi kwiindawo zeengqondo ezithola igazi phakathi komzobo we-cerebral. Le mimandla ibandakanya i -lobe ye-parietal, i-lobe ye -temporal kunye ne- capsule yangaphakathi kunye ne-thalamus.
Ukuba yonke i-artery yecerebral ephakathi ivinjiwe, ngoko ke umphumo ngumtya omkhulu wesitya ochaphazela yonke indawo yendawo ye-artery yecerebral-yimihlaba yonke yengqondo efumana igazi ngaphakathi kombhobho we-cerebral. I-MCA isiphazamiso esibangela ukulahleka kweelwimi , ubuthathaka kwicala eliphambene lomzimba, ulahleko lwentlupheko kwicala eliphambene lomzimba kunye neziphene zembono.
Ukuba kuphela igatsha elincinci lombhobho we-cerebral uvalwe, ke umphumo wesibalo esincinci sisiphumo, sichaphazela icandelo elincinci lomhlaba we-artery cerebral. Oku kunzima kakhulu.
Kutheni Kuthiwa I-Artery Cerebral Artery Stroke?
Izigulane ze-MCA ngokuqhelekileyo ziyi-embolic ngokuchasene ne-thrombotic.
Oku kuthetha ukuba ngokuqhelekileyo uhlangothi lwe-artery cerebral lwe-artery lubangelwa liphulo legazi elihamba ukusuka kwenye indawo emzimbeni, ngokuqhelekileyo ukusuka entliziyweni okanye kwi-artery carotid, kwaye ifakwe ngaphakathi komzobo we-cerebral, uvimba ukuhamba kwegazi.
Kukho iziganeko zobungozi be-MCA, eziquka isifo senhliziyo , isifo se- carotid kunye neemeko ezinobungozi ezinokubangela ukubetha kwimeko ethile kwingqondo, njenge-cholesterol ephezulu, i-hypertension ne-diabetes.
Ziphi iArterial Cerebral Arteries?
Kukho imitha yesibini ye-cerebral arteries: intsimbi ye-cerebral ye-middle middle kunye ne-left middle cerebral artery. Iimpawu ze-cerebral eziphakathi kunye nekhohlo ziyimimandla yegazi ebalulekileyo ephuma kwicala le-carotid yangaphakathi nekhohlo.
Umzobo ngamnye wangaphakathi we-carotid yisebe le-artery okanye i-carotid, eyimimandla emikhulu yegazi ehlangothini ngalunye entanyeni. Iimpawu ze-carotid eziqhelekileyo kunye nezisekhohlo ziqhelekileyo zibukela imifanekiso yomnye nomnye, kwaye i-artery nganye ye-carotid iyahlula kwi-artery carotid yangaphandle kunye ne-artery carotid yangaphakathi. Emva koko, ngaphakathi kwikhono, umzobo we-carotid yangaphakathi uqhubeka uhlula kwimibhobho emininzi eyenza igazi kwingqondo, eyona nto ibaluleke kunayo yonke into ephakathi kwe-artery cerebral.
Nganye i-cerebral arteries nganye ihambisa ingxenye ebalulekileyo yengqondo kunye ne-oksijini enezityebi ezicebileyo nezondlo.
Uthini i-Artery Cerebral Artery?
Iimitha zengqondo egazini igalelo legazi ukuhambisa i-oxygen kunye nezondlo kwiingqondo. Imibhobho eyahlukeneyo yenziwe njengamapayipi ahamba kwimimandla eyahlukeneyo yengqondo. Umzo ngamnye uhlinzekela icandelo elithile lobuchopho.
Icandelo lomchopho ofumana igazi kwi-artery ethile kuthiwa 'yintsimi' yaloo mzobo.
I-artery midage ye-cerebral inikezela insima enkulu engqondweni equka i-lobe ye-temporal, i-lobe ye-parietal, i-capsule yangaphakathi, i-thalamus kunye nxalenye ye-lobe yangaphambili. Ngoko ke, ukuba ukuphuma kwegazi phakathi kombhobho we-cerebral isifo, imisebenzi edlalwa yile mimandla yengqondo iyancipha.
Uxilongo, unyango kunye nokubuyiswa
I-MCA isithintelo phakathi kweentlobo eziqhelekileyo ezibonakalayo zokubetha, kwaye unokufuna kwakhona ukuba uphando lweengqondo zokuqinisekisa ukuxilongwa.
Ngenxa yokuba isifo se-MCA sinokuba sisifo esikhulu, imeko yexesha elifutshane ithathwa ngokunyamekela . Abanye abantu abafumana unxephezelo lwe-MCA ngabaviwa bonyango oluphuthumayo kunye ne- TPA okanye abacebisi begazi, ngelixa abanye bangadinga ukuphathwa ngokucokisekileyo kokusetyenziswa kwamanzi kunye nokujonga okufutshane.
ILizwi
Ukuba wena okanye umntu obathandayo uye wafumana isifo soxanduva lwe-MCA, ngoko ukuhlaziywa kwakho kungathatha ixesha, ingakumbi ukuba yonke iMCA ivaliwe, okubangele ukushaya kwesifo esikhulu. Ukubuyiselwa kwexesha elide nokuvuselelwa kungathatha inyanga okanye neminyaka. Nangona kunjalo, izibetho ezinzima zingabangela ukuphucula kakuhle, kwaye abaninzi abantu abanamava a-MCA bayakwazi ukufumana kwakhona okanye yonke into emva kokubetha.
