I-Mitral stenosis

Isisu se-mitral valve yisifo senhliziyo esitholakale, sibonakaliswe ekunciphiseni kwesifinyelelo se-atrioventricular orifice. Ngokuvamile lesi sifo sihlanganiswa nemikhuba yamanye amagagasi. Ukunciphisa indawo yesikhanyiso se-mitral valve kuvimbela ukugeleza kwegazi okujwayelekile. Ngenxa yalokho, umthwalo okhuphukile ohlangothini olulungile uholela ekunciphiseni komjikelezo omkhulu wegazi, futhi, kamuva, ukuhluleka kwenhliziyo.

Izimbangela ze-stenosis ye-valve mitral

Phakathi kwezici ezibangela ekuthuthukiseni kwe-mitral valve stenosis, kukhona:

• I-rheumatism njengengcindezi emva kwe-angina;
• ukukhubazeka kwenhliziyo okuzalwa ngaphakathi;
• izicubu, i-thrombi ne-calcium idijithali kuma-valve.

Izimpawu ze-stenosis ye-valve mitral

Esikhathini sokuqala sesi sifo, izimpawu ezinzima zesimo se-stenosis azikho, futhi ukubonakala kwesiguli kuhlala kungashintshi ngokuphelele. Kancane kancane kukhona ukuphefumula okuncane, ukuphazamiseka, ukukhathala okukhulu. Ngezinye izikhathi ukukhwehlela ne-hemoptysis kubonakala. Uma i-dyspnea ingozi yokuchofoza, ukuthuthukiswa kwe-edema ye-pulmona kungenzeka. Ubuso besiguli bubukeka bubala; Iphuzu lempumlo, izindebe, izindlebe nezandla zinezinyosi eziyingozi. Engxenyeni engezansi ye-sternum, okuthiwa "inhliziyo hump" yenziwa. Iziguli zibhekene ne -fibrillation ye-atrial .

Ukuphakama nge-stenosis ye-valve ye-mitral kubalulekile ekuxilongweni. Ochwepheshe ngesikhathi sokuhlolwa, ngisho nosizo lwe-phonendoscope evamile, angenza ukuxilongwa, athole "ukuchofoza" lapho evula i-valve mitral, evela ekungeneni kwamagagasi akhe ahlanganisiwe. Lapho indawo ye-stenosis ikhula, kukhona umsindo wokushaya futhi uma ulalela i-diastole. Ukubaluleka okukhulu ekuguquleni kwesifo se-hemodynamics kunomfutho ophezulu emthini nasendlini yamaphaphu, njengoba kuphazamiseka ukushintshaniswa kwe-oxygen ne-carbon dioxide.

Ukwelashwa kwe-mitral valve stenosis

Ukungenelela kokusebenza kuyindlela esemqoka yokwelashwa kwe-stenosis ye-valve. Ukusebenza kunconywa ukuze ubuyisele ukugeleza kwegazi okujwayelekile. Umthambo we-Coronary overpass ukuhlanganiswa manje usuvamile. Njengomthetho, ngemuva kokungenelela okuhlinzekwa ngokulungiswa kahle ngokuhlelwa nokusetshenziswa kwemithi elwa namagciwane kanye namalungiselelo okubuyisela izicubu ze-myocardial, ukufika kuyabuya.

Uma lokho kungenzeki, isiguli kufanele sithole ukwelashwa okuqhubekayo ukuze kuvinjelwe izinkinga.

Kubalulekile! Iziguli ezine-stenosis ye-valve ye-mitral kumele zilinganiswe emisebenzini yemvelo futhi zibheke ukulinganisela kosawoti lwamanzi.
