I-Vasoconstriction Syndrome kunye neStroke
Isifo se-vasoconstriction syndrome (RCVS) esibuyiselwayo sinobuchoko sibonakaliswe yimpawu ezimbini eziphambili. Eyokuqala ngowokuqala ngokukhawuleza kwintloko yokuduma . Owesibini ubukho beendawo zokunciphisa okanye "i-vasoconstriction" apho udonga lunye okanye eminye imiyibetho echotsheni luneenkampu ezivimbela ukuphuma kwegazi. Ezi nkalo zinokuthi zifumaneke ngokulula ngecangter angiogram , nangona ngamanye amaxesha nazo ziyabonakala nge -angiography yamandla amakhulu (magratic resonance angiography) .
I-vasoconstriction ye-cerebral yokuguqulwa ingakwazi okanye ingakhokelela ekubetheni . Kwiimeko ezininzi, iimpawu zesifo sobungozi zivela kodwa zatshintshwa ngokupheleleyo emva koko. Nangona kunjalo, abanye abantu banokushiywa ngamatyala angunaphakade. Esi siganeko sinokubangela ukugunjwa nokufa.
Yintoni i Stroke?
I-stroke isifo esibangela iimitha ezibangelwa kwaye ngaphakathi kwengqondo. NguNombolo 5 ebangela ukufa nokubangela ukukhubazeka eUnited States. I-stroke iyenzeka xa isitya segazi esithwala i-oksijeni kunye nezondlo kwiingqondo zivaliwe i-clot okanye i-bursts (okanye i-break). Xa oko kwenzeka, inxalenye yengqondo ayinakufumana igazi (kunye ne-oksijeni) iyayidinga, ngoko iseli kunye neengqondo zeesilini ziyafa.
Isisu sisenokubangela ukuba i-clot ivimbele ukugeleza kwegazi kwingqondo (ebizwa ngokuba yi- ischemic stroke ) okanye ngesitya segazi esithintelayo kunye nokukhusela ukuphuma kwegazi kwingqondo (ebizwa ngokuba yi- stroke ephazamisayo ). I- TIA (ukuhlaselwa kwe-ischemic ehamba phambili), okanye "ukubetha kweminye", kubangelwa i-clot yesikhashana.
I-RCVS inokubangela i- ischemic okanye i- stroke ephazamisayo, ngokuqhelekileyo ngendlela yesifo se-subarachnoid .
Izinto Zingozi ZeStroke
- Ubudala - Ilungelo lokuba nesifo sokubethwa ngokuphindwe kabini kwishumi ngalinye leminyaka yobomi emva kweminyaka yobudala engama-55. Nangona i-stroke ixhaphakile phakathi kwabalupheleyo, abaninzi abantu abangaphantsi kwe-65 banemivimbo.
- Ulungelelwano (imbali yentsapho) - Ingozi yakho yengozi ingaba enkulu xa umzali, ootatomkhulu, udade okanye umzalwana sele enesifo.
- Uhlanga - abaseMerika-baseMelika banomngcipheko ophezulu wokufa ngenxa yesifo esibuhlungu kuneCaucasians. Oku kungenxa yokuba abantu abamnyama baneengozi ephezulu yexinzelelo lwegazi, isifo sikashukela kunye nokukhuluphala.
- Ubundlobongela (ngokwesini) - Unyaka ngamnye, abafazi banemivimbo engaphezulu kunamadoda, kwaye ukubethelwa komzimba kubulala abaninzi abasetyhini kunamadoda. Ukusetyenziswa kweepilisi zokulawula ukuzalwa, ukukhulelwa, imbali ye-preeclampsia / eclampsia okanye isifo sikashukela, isifo sikashukela, ukusetyenziswa komlomo, kunye nokubhema, kunye ne-post-menopausal ye-hormone yokwelapha ingabangela ingozi ekhethekileyo yokubethelwa kwabasetyhini.
- Ukubetha kwangaphambili, i-TIA okanye ukuhlaselwa yintliziyo -Ingozi yokubetha umntu oye wayesebenayo kaninzi ngamaxesha omntu ongenalo. Ukuhlaselwa kwe-ischemic yexesha elifutshane (i-TIAs) "izibhengezo zokulumkisa" ezivelisa iimpawu ezinjenge-stroke kodwa akukho monakalo ohlala njalo. I-TIA i-predictors eqinileyo ye-stroke. Umntu onomnye okanye ngaphezulu kwe-TIAs cishe amaxesha angama-10 amathuba okuba nesigxina kunomntu ofanayo kunye nobulili ongenalo. Ukuqaphela nokunyanga i-TIAs kunokunciphisa umngcipheko we-stroke enkulu. I-TIA imele ithathelwe ingqalelo kwimeko yexakeka yonyango kwaye ilandelwe ngokukhawuleza kunye neengcali zonyango. Ukuba unesifo senhliziyo, usemngciphekweni omkhulu wokuba nesifo, nokuba.
Ngubani ochaphazelekayo yiRCVS?
I-RCVS ithintela abafazi ngokuphindaphindiweyo kunamadoda, esona siqhelo emva kokuzala.
Yintoni eyenza iRCVS?
Isizathu seRCVS asiyazi, kodwa kucatshangelwa ukuba kubangelwa ukuphazamiseka okudlulileyo kwodonga olujikelezayo, olukhokelela ekunciphiseni kwalo. Izinto ezininzi zidibene neRCVS, kuquka:
- I-serotonin i-reuptake inhibitors (iSRRIs)
- Ama-decongestants ase-Nasal ane- pseudoephedrin okanye ephedrine
- Ergotamine
- Tacrolimus
- Uthiko lweNicotime
- ICocaine
- Marijuana
