I-stenosis ye-mitral valve yintliziyo yesifo efunyenweyo, ibonakaliswe ekunciphiseni kwe-orifice ye-atrioventricular orifice. Ngokuqhelekileyo le nto yokukhubazeka idibaniswe kunye neenkohlakalo zamanye amagatya. Ukunciphisa indawo ye-lumen ye-mitral valve ivimbela ukuhamba kwegazi ngokuqhelekileyo. Ngenxa yoko, umthwalo okhulayo kwi-atrium elungileyo ukhokelela ekunciphiseni isangqa esikhulu sokujikeleza kwegazi, kwaye, emva koko, kwintliziyo yokuhluleka.
Iimbangela ze-stenosis ye-mitral valve
Phakathi kwezinto ezifaka isandla ekuphuhliseni i-mitral valve stenosis, kukho:
- I-rheumatism njengengxube emva kwe-angina;
- ziphosakeleyo zentliziyo;
- izicubu, i-thrombi ne-calcium deposits kwiipopu ze-valve.
Iimpawu ze-stenosis ye-mitral valve
Kwinqanaba lokuqala lesi sifo, iimpawu ezinzima ze-stenosis azikho, kwaye ukubonakala kwesigulane kuhlale kungatshintshi. Kancinci kukho ukuphefumula okufutshane, ukuphala, ukukhathala okuphezulu. Ngamanye amaxesha ukukhwehlela kunye ne-hemoptysis kuphawulwe. Ukuba i-dyspnea iyingozi yengozi, ke ukuphuhliswa kwe-edema yamapulmoni kunokwenzeka. Ubuso bomguli bubonakala bubala; Isipho sempumlo, imilomo, indlebe nezandla zine-cyanotic hue. Kwinqanaba elincinane le-sternum, oko kuthiwa "intliziyo yentliziyo" yenziwa. Izigulane zibonakaliswa yi- fibrillation ye-atrial .
Ukuxhaswa nge stenosis ye-mitral valve kubalulekile ekuxilongweni. Ingcali ngexesha loviwo, nangona uncedo lwe-phonendoscope yesiqhelo, lunokuthi luchothoze, lufake "ucofa" xa uvula i-valral valve, evela ku-oscillation of valves. Xa indawo ye-stenosis ikhula, kukho umsindo wokubetha kunye nokuphulaphula i-diastole. Ubaluleke kakhulu ekutshintsheni kwempilo ye-hemodynamics inexinzelelo oluphezulu kwi-artery kunye ne-vein yemiphunga, njengoko utshintshiselwano lwe-oksijini ne-carbon dioxide liphazamiseka.
Unyango lwe-mitral valve stenosis
Ukungenelela kokusebenza yindlela eyona nto yokonyango kwe-stenosis ye-valve. Uphando luyanconywa ukuze ubuyisele
Ukuba umsebenzi awunakwenzeka, isigulane kufuneka sithole unyango oluqhubekayo ukuze lukhusele iingxaki.
Kubalulekile! Izigulane ezine-stenosis ye-mitral valve kufuneka zilinganiswe kwimisebenzi yenyama kwaye zigcine ukulinganisela kweseyile.
