Umbuzo: Kanjani Okuwusizo Ingabe I-Aortic Valvulotomy Ye-Aortic Stenosis?
Umama wami osekhulile uhlushwa i-aortic stenosis, futhi aphefumula kakhulu. Isazi se-cardiologist sakhe sicabanga ukuthi usekhulile futhi sigula ukuhlinzwa kwenhliziyo, futhi siphakamisa inqubo ebizwa ngokuthi i-aortic valvulotomy. Ungangitshela ngani ngale nqubo?
Impendulo: I- aortic stenosis yisimiso lapho i-valve ye-aortic (i-valve egcina ukuvulwa phakathi kwe-ventricle kwesokunxele ne-aorta) ifinyelelwe nge-calcium deposits, futhi ayisakwazi ukuvula ngokuphelele.
Ngenxa yalokhu kuvinjelwa, imisipha yenhliziyo kufanele isebenze kanzima ukupompa igazi enhliziyweni, futhi ukuhluleka kwenhliziyo kuvame ukuphumela. Ukuphela kokwelashwa okuphumelelayo kwe-aortic stenosis kungukuqeda ukuvinjelwa ku-valve, ngokujwayelekile ngokufaka esikhundleni se-valve ye-aortic. Nakuba ukuguqulwa kwe-valor e-aortic kuyasebenza kakhulu ekwelapheni i-aortic stenosis, kudinga ukuhlinzwa okukhulu kwenhliziyo evulekile, futhi kuyingozi kumaziguli asebekhulile.
- Funda mayelana ne-aortic stenosis kanye nokuphathwa kwayo.
I-aortic valvulotomy yindlela encane engavamile yokuphatha i-aortic stenosis. Ku-valvulotomy, i-catheter ibhaluni idluliselwa ngaphesheya kwe-valve ye-aortic, futhi iyancipha ngaphansi kwengcindezi ephakeme. Ukufakela ibhaluni kuhloswe ukuphula ezinye izimali ze-calcium ku-valve, ngaleyo ndlela uvumela i-valve ukuthi ivule ngokugcwele, futhi ikhulule ingxenye yezingqinamba.
Ezigulini ezincane ezinezinhlobo zokubeletha ze-aortic stenosis, i-valvulotomy ngokuvamile iyindlela enhle.
Ngeshwa, kubantu asebekhulile abanamaphini ama-aortic amaningi abhalisiwe, imiphumela ene-valvulotomy ayilungile. Nakhu okushiwo i- UpToDate , irekhodi lobuchwepheshe labodokotela kanye neziguli, kufanele lisho mayelana ne-valvulotomy kubantu asebekhulile:
"Ezichungechungeni zomlando, izinkinga ezinkulu (ukushaywa yisifo sokushaya isisu, ukuvuselelwa kwe-aortic, i-infarction ye-myocardial, izinkinga ezinkulu ezihlobene nokufinyeleleka) zenzeka cishe ezigidini ezingu-10 kuya kwezingu-20 zamaphesenti.I-restenosis kanye nokuwohloka komzimba kwenzeka ezimweni eziningi ezinyangeni ezingu-6 kuya kwezingu-12, kanti umphumela wesikhathi eside ufana nomlando wemvelo we-aortic stenosis engaphenduliwe. "
Lokhu kusho ukuthini izinto ezimbili. Okokuqala, kulabo asebekhulile, izinga lezinkinga ezinkulu ezivela ku-valvulotomy (ikakhulukazi isifo, ukuhlasela kwenhliziyo, nokuvuselelwa kwe-aortic ) kuphezulu kakhulu. Empeleni, kufinyelela ku-20% lalezi ziguli ziyafa ngaphambi kokushiya esibhedlela. Lezinga lokucindezela liphakeme kunalokho okuvame ukubikwa ezigulini asebekhulile ezinomsebenzi wokuguqula i-aortic valve.
Okwesibili, i-valvulotomy ngokuvamile ayisebenzi kahle kakhulu, futhi umphumela wesikhathi eside ufana neziguli ezingatholi ukwelashwa nhlobo.
Naphezu kwale miphumela, i-valvulotomy isasebenza ngezinye izikhathi. Isibonelo, i-valvulotomy ingasetshenziswa njenge "bhuloho" ekuhlinzeni ukuguqulwa kwamagagasi. Okungukuthi, ingasetshenziswa ngomzamo wokuthuthukisa okwesikhashana umsebenzi wenhliziyo ngokwanele ukuvumela ukuhlinzwa kwenhliziyo evulekile ukuqhubeka ngokuphepha.
Kodwa-ke, uma ucabangela imiphumela emibi evame ukubonwa nge-valvulotomy ezigulini ezigugile, kufanele uqiniseke ukuthi ukhuluma ne-cardiologist yomama wakho mayelana nezinye izinketho. Ngaphandle kokufakelwa kwe-valve yokuhlinzwa, lezi ezinye izinketho zingase zihlanganise uhlobo oluhlukile lwezokwelapha ezisuselwa ku-catheter ye-aortic stenosis, okuthiwa i- transcatheter aortic valve implantation (TAVI) .
