Ulwabizo olumanzi lubizwa ngokuba negama kuba lichaphazela enye okanye eminye imimandla yengqondo ebizwa ngokuthi 'indawo ephantsi komhlaba.'
Iindawo eziphantsi kwamanzi ziindawo zengqondo ezixhaswa ngegazi ezivela kumaqela amabini ahlukeneyo. Ukuba kukho ukucinywa okanye ukuphazamiseka kokuhamba kwegazi kweminye imithwalo yegazi, ingaba yingxaki-nto leyo ibangelwa ukubetha kwamanzi.
Iimpawu kunye nokuxilongwa kwamanzi
Iindawo ezisemanzini zengqondo zingathinteka ngokunciphisa ukuhamba kwegazi, ezinokubangela ukubetha. Izibonakaliso zesifo sokuhlaselwa kwamanzi ziquka ubuthathaka kunye / okanye ukulahleka kombono ngakwesokudla okanye kwicala lasekhohlo lobuso, ingalo okanye umlenze. Ukuba uhlaselo oluthile lubangelwa ngumxhesho ophantsi kakhulu wegazi okanye ukulahleka kwegazi, iimpawu ezinokuthi zichaphazele iindawo ezifanelekileyo kunye nekhohlo.
I-stroke yamanzi ingasoloko ifunyaniswa ngembali yengqondo kunye nokuhlolwa komzimba kwaye iyakwazi ukuchongwa kwi-brain CT noma kwi-MRI yengqondo.
Izizathu zokubetha kwamanzi
Iskrakra Stroke
Igazi lokuphazamiseka kwegazi kummandla wengqondo lingabangela isifo se- ischemic kuyo nayiphi na indawo yengqondo, kubandakanywa nemimandla yamanzi. I-Iskemia ibangela indawo yengqondo ukuba 'ilambile' egazini. Ngenxa yokuba igazi linika izondlo ezibalulekileyo kunye ne-oksijeni, ummandla ochaphazelekayo wengqondo awukwazi ukusebenza kwisimo se-ischemia , esiphumela isifo.
Iindawo ezisemanzini zengqondo zifumaneka kumasebe ekupheleni ekupheleni kweendawo eziselunxwemeni (iinkqubo zokubonelela ngezixhobo.) Oku kuthetha ukuba iiseti ezimbini ezihlukeneyo zeetriyiti zinika igazi kwiindawo eziphantsi komhlaba. Eli lungiselelo libonakala ngathi liza kukhusela iindawo ezisemanzini ukusuka kwi-ischemia, kodwa ayenjalo.
Enyanisweni, iindawo eziphantsi kwamanzi zixhomekeke kuzo zombini iisethi zeetriyri ukwenzela ukubonelela ngegazi, ngoko ke ukuba enye inkqubo yokunikezelwa kwegazi iphazamisekile nge-clot yegazi, ummandla wamanzi ochopho uxhamla ukuphazamiseka kwegazi, okubangelwa ukuphazamiseka kwegazi.
Umthamo oMzantsi weFluid / Uxinzelelo lwegazi oluphantsi
Ngenxa yokuba iindawo eziphantsi kwamanzi ziindawo ezikude kakhulu ezibonelelwa ngeenkqubo zokubonelela ngegazi, ukuhamba kwegazi okwaneleyo kunye nokunyanzelwa kwegazi kufuneka kugcinwe ukuqinisekisa ukuba igazi elaneleyo liqhutyelwa kule mimandla. Iindawo ezihlambulukileyo zisesichengeni esiphezulu ngexesha lokunyuka kwexinzelelo lwegazi. Ukuba ukuhamba kwegazi ephantsi kwiindawo eziphantsi kwamanzi kuqhubeka ixesha elide kunemizuzu embalwa, izicubu ezinxwemeni ziqala ukufa, ezibangela ukubetha ngenxa yexabiso eliphantsi legazi.
Iziganeko eziqhelekileyo zokubetha kwamanzi ziquka iziganeko ezichaphazela igazi kwiinkonzo. Ukuhlaselwa yintliziyo, okuchaphazela amandla okupompa kwentliziyo, okubangela ukuba kunciphise kakhulu ukuhamba kwegazi ukuya kwingqondo. Iindawo ezihlambulukileyo zingasengozini yokuxinzelelo lwegazi oluphantsi kubantu abaye baqhubela phambili i-carotid stenosis, eyokunciphisa imithwalo yegazi entanyeni ephethe igazi kwingqondo.
Ezinye iimeko zingabangela uxinzelelo lwegazi oluzelelwe okanye oluphantsi.
Iimeko ziquka ukukhulelwa kwamanzi amaninzi, okubangela ukuba umthamo ophantsi we-fluid kuwo wonke umzimba. Izifo ezithintekayo, ezifana ne-sepsis, usulelo oluye lwasasazeka kulo lonke igazi, lunokubangela ukuba uxinzelelo lwegazi luyeke ngokuphawulekayo, olunokubangela ukubetha kwamanzi. Kwaye ukuphuma kwegazi, okungabangela ukulimala kakhulu kunye nokulimala, kunokubangela ukuba ulahleko lwegazi lulahleke kangangokuba ingqondo ayifumani ukunikezelwa kwegazi kwiindawo ezisemanzini.
Unyango lwezitshizi
Njengazo zonke izibetho, imivimbo yamanzi idinga ukunikwa ngonyango. Ukulawulwa kwemivalo yamanzi kubandakanya ukuqwalaselwa okufutshane kunye nokulawulwa ngonyango.
Ukuba unayo i-ischemic-stroke ephazamisayo eyabangelwa i-clot yegazi, kufuneka ulindele ukufumana unyango lwe-stroke ejoliswe kumaconsi egazi kunye nokuzinza kwezokwelapha. Ukuba uye waba nesifo esiphambukayo ngenxa yokulahleka kwegazi okanye ukunyanzeliswa kwegazi, ke unyango lwakho luyakwazi ukugxininisa ekugcineni umbane olwaneleyo kunye negazi.
ILizwi
Isibilini sisiganeko esikhulu esitshintsha ubomi bakho. Njengoko uhlaziya kwi-stroke yakho, uya kufumana uncedo lwezokwelapha oluchonga ukuba ngaba unobungozi bokuba neengozi . Ukuba ufunda ukuba unayo nayiphi na ingozi yengozi, ungathatha amanyathelo okuthintela olunye uhlangothi oluya kwenzeka.
