Mitral stenosis

Mphuno ya mitral ndi matenda a mtima omwe amapezeka, powonetsetsa kumanzere kwao kwa atrioventricular orifice. Kawirikawiri matendawa amaphatikizidwa ndi mabala ena a ma valve. Kuchepetsa dera la lumen la valve mitral kumateteza kuti magazi aziyenda bwino. Chotsatira chake, katundu wochulukirapo pa malo oyenerera amachititsa kuchepetsedwa kwa mzunguwu waukulu wa magazi, ndipo, kenako, mtima wolephera.

Zifukwa za stenosis ya valve mitral

Zina mwazimene zimapangitsa kuti mavitral valve stenosis ayambe, pali:

• Rheumatism ngati vuto pambuyo pa angina;
• zofooka za mtima zakufa;
• matumbo, thrombi ndi calcium deposits pa ziphuphu za valve.

Zizindikiro za stenosis ya valve mitral

Pa nthawi yoyamba ya matendawa, zizindikiro zoopsa za stenosis siziripo, ndipo maonekedwe a wodwala amakhalabe osasintha. Pang'ono pang'onopang'ono pali mpweya wochepa, mapeto, kutopa kwambiri. Nthawi zina chifuwa ndi hemoptysis zimadziwika. Ngati dyspnea ndizoopsa, ndiye kuti chitukuko cha pulmonary edema chingatheke. Maonekedwe a wodwalayo amaonekera bwino; Mphuno ya mphuno, milomo, makutu ndi manja ali ndi chimbudzi chosakanikirana. M'munsi mwa sternum, chomwe chimatchedwa "mtima hump" chimapangidwa. Odwala amadziwika ndi khansa ya m'thupi .

Kuthamanga ndi stenosis ya valve mitral n'kofunika kwambiri pozindikira. Katswiri pa nthawi yofufuzidwa, ngakhale atathandizidwa ndi phonendoscope yodziwika bwino, amatha kupeza matenda, atapeza "chotseketsa" pamene atsegula valve ya mitral, yomwe imachokera ku kuchotsedwa kwa magalasi ake. Pamene malo a stenosis amakula, pamakhala kuwomba komanso kumvetsera tchizi. Kufunika kwakukulu pa kusintha kwa matenda a hemodynamics kumakhala kosautsa kwambiri mu mitsempha ndi mitsempha ya mapapo, monga kusinthanitsa kwa mpweya ndi carbon dioxide.

Chithandizo cha mitral valve stenosis

Njira yogwiritsira ntchito ndi njira yaikulu yothetsera stenosis ya valve. Ntchito ikulimbikitsidwa kuti mubwezeretse magazi ozungulira. Mitsempha ya Coronary yodutsa pamtengowo umakhala wamba. Monga mwa lamulo, atatha opaleshoni ndi kukonzanso bwino dongosolo ndi kugwiritsa ntchito maantibayotiki ndi kukonzekera kubwezeretsa minocardial minofu, kubweranso kumabwera.

Ngati opaleshoniyo sichitheka, wodwalayo ayenera kulandira chithandizo chothandizira kuti athetse mavuto.

Zofunika! Odwala ndi stenosis a valve mitral ayenera kuyeza muzochita zowonongeka ndi kusunga mchere wamchere.
