Funso: Kodi N'kofunika Bwanji Aortic Valvulotomy Kwa Aortic Stenosis?
Mayi anga okalamba akuvutika ndi aortic stenosis, ndipo amatha kupuma pang'ono. Katswiri wake wamaganizo akuganiza kuti ndi wamkulu kwambiri ndipo akudwala chifukwa cha opaleshoni ya mtima, ndipo akupereka njira yotchedwa aortic valvulotomy. Kodi mungandiuze chiyani za njirayi?
Yankho: Aortic stenosis ndizofunika kuti valve ya aortic (valve yomwe imateteza kutsegula pakati pa ventricle yakumanzere ndi aorta) imadzazidwa ndi ndalama za calcium, ndipo sichikhoza kutsegula kwathunthu.
Chifukwa chachisokonezo ichi, minofu ya mtima iyenera kugwira ntchito molimbika kwambiri kupopera magazi kuchokera mumtima, ndipo nthawi zambiri mtima umalephera. Njira yokhayo yothandizira aortic stenosis ndiyo kuthana ndi kutsekeka kwa valve, makamaka pochita opaleshoni m'malo mwa valve ya aortic. Ngakhale kupuma kwa valve kwa aortic kumathandiza kwambiri pochiza aortic stenosis, kumafuna opaleshoni yaikulu yotsegulira mtima, ndipo ndi yoopsa kwa okalamba.
- Werengani za aortic stenosis ndi mankhwala ake.
Vallolotomy ya Aortic ndi njira yochepa yochizira aortic stenosis. Mu valvulotomy, cathatine ya baluni imadutsa pa valve ya aortic, ndipo imakhudzidwa ndi kuthamanga kwakukulu. Kusokoneza buluni kumatanthauza kupasula ma pulogalamu ya calcium pa valve, motero mpata wotsegulira kutsegula kwathunthu, ndikuthandizira gawo lina lakutchinga.
Odwala achinyamata omwe ali ndi maubongo otha msinkhu wa aortic stenosis, valvulotomy nthawi zambiri ndi yabwino.
Mwamwayi, kwa anthu achikulire omwe ali ndi valve aortic kwambiri, zotsatira ndi valvulotomy sizinali zabwino. Apa pali zomwe UpToDate , mauthenga apakompyuta kwa madokotala ndi odwala, ayenera kunena za valvulotomy kwa anthu okalamba:
"M'mabuku a mbiri yakale, mavuto aakulu (stroke, aortic regurgitation, matenda a myocardial infarction, mavuto akuluakulu okhudzana ndi zovuta) anachitika pafupifupi pafupifupi 10 mpaka 20 peresenti ya odwala.Restenosis ndi kuwonongeka kwa matenda kumachitika nthawi zambiri mkati mwa miyezi 6 mpaka 12, ndipo zotsatira za nthawi yaitali zimakhala zofanana ndi mbiri ya chilengedwe ya aortic stenosis yosatulutsidwa. "
Izi zikutanthauza zinthu ziwiri. Choyamba, kwa okalamba, kuchuluka kwa mavuto aakulu kuchokera ku mavupa (makamaka kupwetekedwa, kupweteka kwa mtima, ndi kubwezeretsedwa kwa aortic ) ndipamwamba kwambiri. Ndipotu, mpaka 20 peresenti ya odwalawa amwalira asanachoke kuchipatala. Izi ndizopambana kuposa momwe zimafotokozera okalamba omwe ali ndi valve m'malo mwake.
Chachiwiri, kugwiritsira ntchito ziphuphu nthawi zambiri sikungagwire ntchito bwino, ndipo zotsatira za nthawi yayitali ndizofanana ndi odwala omwe samalandira chithandizo.
Ngakhale zotsatira izi, nthawi zina amagwiritsidwa ntchito. Mwachitsanzo, valvulotomy ingagwiritsidwe ntchito ngati "mlatho" kuti uchitidwe opaleshoni ya valve. Izi zikutanthauza kuti zingagwiritsidwe ntchito poyesa kugwira bwino ntchito ya mtima mokwanira kuti opaleshoni yotsegulira mtima ipite mosavuta.
Komabe, poganizira zotsatira zoipa zomwe zimawonedwa ndi valvulotomy kwa odwala okalamba, muyenera kukhala otsimikiza kuti muziyankhula ndi katswiri wa mtima wanu zazinthu zina. Kuwonjezera pa malo opangira opaleshoni, njira zinazi zingaphatikizepo mtundu wina wa catheter-based treatment for aortic stenosis, yotchedwa transcatheter aortic valve implantation (TAVI) .
Mukufuna kuphunzira zambiri? Onani mutu waToDate, "Matenda a Mtima" kuti mudziwe zambiri zachipatala.
