Mubvunzo: Zvakakosha Sei Aortic Valvulotomy KwaAortic Stenosis?
Amai vangu vakwegura vari kutambura ne aortic stenosis, uye inopfupika kufema. Nyanzvi yake yepfungwa inofunga kuti yakwegura uye inorwara nekuvhiyiwa kwemoyo, uye iri kuratidza nzira inonzi aortic valvulotomy. Chii chaungandidzidza pamusoro peiyi nzira?
Mhinduro: Aortic stenosis inzvimbo iyo inonzi aortic valve (iyo valve inorinda kuvhura pakati pevhirikiri yekasi uye neaorta) inowedzera nemaricum, uye haichagoni kuzarura zvachose.
Nokuda kwekuvhiringidzika, mwoyo wemisvo inofanira kushanda zvakaoma zvikuru kuputira ropa kubva mumoyo, uye mwoyo kukanganisa kunowanzoguma. Iyo chete inobatsira kurapa aortic stenosis ndechokudzivirira kubviswa mukati mevhavha, kazhinji kuburikidza nekugadzirisa nzvimbo yeaorop valve. Kunyange zvazvo aortic valve kushandiswa inoshanda zvikuru pakurapa aortic stenosis, zvinoda kuvhiyiwa kukuru kwepfungwa, uye kune ngozi kune vakwegura vakura.
- Verenga pamusoro peaortic stenosis uye kurapa kwayo.
Aortic valvulotomy inzira isingasviki pakurapa aortic stenosis. Muvhirivuomyomy, bhaloni catheter inopfuudzwa nepamusoro pemagetsi e-aortic, uye inokonzerwa nepamusoro pekumanikidza. Kuvharidza ibhaluni kunoreva kuputsika imwe yemaricum inosvika pavhavha, nekudaro kubvumira kuti valve izarure zvakakwana, uye kubvisa chikamu chekudzivirira.
Muvatachiri vaduku vane maitiro ehutano hwe aortic stenosis, valvulotomy inowanzova yakanaka.
Zvinosuruvarisa, kune vanhu vakwegura vane zvivako zvakanyanya zvakaenzana aortic valves, zvinowanikwa nev valvulotomy hazvina kunaka. Hezvino izvo UpToDate , magwaro ekunyorwa kwechiremba nevarwere, inofanira kutaura pamusoro pev valvulotomy kuvanhu vakwegura:
"Muzvinyorwa zvezvakaitika kare, zvinetso zvakakomba (stroke, aortic regurgitation, myocardial infarction, zvinetso zvakakomba-zvakabatana) zvakaitika munenge kusvika 10 kusvika ku20 muzana yevarwere.Restenosis uye kuora kwechipatara zvinowanzoitika mumwedzi yakawanda kusvika pamwedzi gumi nematanhatu, uye mugumo wenguva yakareba unofanana nenyaya yezvakaberekwa yeasortic stenosis isina kutorwa. "
Izvi zvinorevei zvinhu zviviri. Chokutanga, kune vakwegura, uwandu hwezvinetso zvakakomba kubva muvhuvulotomy (kunyanya kurwadziwa, kurwadziwa kwemoyo, uye aortic kudzoka ) zvakanyanya. Kutaura zvazviri, kusvika 20% yevashandi ava vanofa vasati vabva muchipatara. Izvi zvinokonzerwa nehuwandu hwepamusoro huwandu kupfuura inowanzotaurwa kune vakwegura vakwegura vane aortic valve replacement.
Chechipiri, kuvimba kwevhutulotomy kazhinji hakushandi zvakanaka, uye kuguma kwenguva yakareba kwakangofanana nevarwere vasingagamuchiri kurapwa zvachose.
Pasinei nemigumisiro iyi, kuvhara ropa kunoshandiswa dzimwe nguva. Semuenzaniso, valvulotomy inogona kushandiswa se "bhulogi" kumashandisirwo ekugadzirwa kwevhavha. Izvozvo zvinogona kushandiswa mukuedza kujekesa kwenguva pfupi basa remwoyo zvakakwana kuti kubvumira kuvhurika kwemoyo kusununguka zvakachengeteka.
Zvisinei, tichifunga nezvekusava nemigumisiro yakaipa inowanzoonekwa neine valvulotomy kune vakwegura varwere, unofanira kunge uine chokwadi chekutaura naamai vako nyanzvi yezvokudya pamusoro pezvimwe zvingasarudzwa. Kuwedzera pane kugadziriswa kwevhavha yekugadzirisa, izvi zvinogona kusanganisira rudzi rwakasiyana rwekate-based based for aortic stenosis, inonzi transcatheter aortic valve implantation (TAVI) .
Unoda kudzidza zvakawanda here? Ona UpToDate musoro unoti, "Dambudziko reMwoyo" yezvekuwedzera kwehutano hwehutano.
