Har'a bofokoli ba pelo bo fumanoeng, aortic stenosis ke e 'ngoe ea tse tloaelehileng ka ho fetisisa: bothata bona bo behiloe ho motho e mong le e mong oa leshome ea lilemo tse 60 ho ea ho tse 65,' me banna ba o utloa bohloko hangata ka makhetlo a mane.
Ka kakaretso, stenosis ke ho fokotsa sekhahla sa valoropo ea aortic, ka lebaka la hore, nakong ea thibelo (systole) ea ventricle e ka letsohong le letšehali, phallo ea mali ho eona ho ea karolong e holimo ea aorta e ba thata haholoanyane.
Mefuta le lisosa tsa aortic stenosis
Ho tloaelehile ho khetholla pakeng tsa congenital malformation le ho e fumana. Boemong ba pele, aorta e na le li-valve tse peli kapa tse le 'ngoe (tse tloaelehileng - tse tharo), tse etsang hore palo ea aortic e fokotsehe,' me ventricle e letšehali e sebetse le mojaro o moholo.
Matšoao a fumanoang ke mafu a hlaseloa ke li-rheumatic processes (ho fihlela ho 10% ea linyeoe), tse atisang ho tsamaea le ho se sebetse kapa stenosis ea metral valve. Bacha ba fumana aortic stenosis ka lebaka la rheumatism .
Matšoao a stenosis ea valve ea aortic e ka boela ea hlaha ka morao oa endocarditis, moo li-valve li kopantsoeng le ho ba thata, ho fokotsa lumen.
Batho ba seng ba hōlile, lefu la atherosclerosis kapa ho tšeloa ha letsoai la calcium (calcinosis) hangata le hlokomeloa ka mahlaseli a liphahlo, e leng se lebisang ho khanyang ea lumen.
Matšoao a aortic stenosis
Maemong a qalang a tsoelo-pele ea mafu, lipontšo tsa stenosis ha li bontšoe, 'me hangata li fumanoa ka phoso nakong ea tlhahlobo ea pelo. Esita le ka mor'a hore u fumane lefu lena, matšoao a ka u etsa hore u eme lilemo tse seng kae.
Mokuli o ngolisitsoe le lefu la cardiologist mme o hlokometse nakong ea lefu lena. Ha nako e ntse e feta, ho phunyeletsoa ha lisele tsa aortic valve ho lebisa moeeng o fokolang le mokhathala o eketsehileng, o tsejoang ka ho khetheha nakong ea boikoetliso. Sena se bitsoa stenosis e leka-lekaneng ea valoropo ea aortic - sebaka sa lumen se fokotseha ho ea ho 1,6-1.2 cm2, ha motho ea phetseng hantle a lekana le 2.5-3.5 cm2.
Karolong ea bobeli ea nts'etso-pele ea lefu la tlhaho (e hlalositsoeng stenosis), boholo ba lumen bo boleloa hore ha bo ho feta 0,7-1.2 cm2. Nakong ea boithaopo ba 'mele, bakuli ba joalo ba tletleba ka botenya le stenocardia (mahlaba ka mor'a sternum), ho khoneha ho khoneha.
Mekhahlelo e latelang ke aortic stenosis e bohale le e bobebe, e khetholloang ke matšoao a kang ho choking, lefu la pelo le li-edema tsa edema. The lumen e fokotseha ho 0.5-0.7 cm2.
Tabeng ea ha stenosis e le congenital, matšoao a eona a bonahala ka lekhetlo la pele bophelong ba bobeli kapa la boraro, 'me lefu lena le hlaha ka potlako.
Phekolo ea aortic stenosis
Ho fihlela joale, ha ho na phekolo e tobileng bakeng sa lefu lena, 'me mekhahlelo ea pele feela e hlahloba tsoelo-pele ea eona.
Likarolong tsa ho qetela, ha ho phunyeletsoa ha lumoropo ea aortic valve e hlahisa motho hampe ka mokhoa o hlalositsoeng ka holimo, ts'ebetso ea ho fetola liphahlo e nepahetse. Ho thata ebile ho kotsi, haholo-holo ho bacha le batho ba baholo. Ka nako e tsoanang, matšoao a tsoelang pele a senya bophelo ba mokuli le ho feta - ka ho ba le aortic stenosis ea bohlokoa ho phela lilemo tse 3 ho isa ho tse 6.
Ntho e 'ngoe ho phekoloa ha valve e ncha ke balloloplasty ea ballo. Tsamaiso ena e kenyelletsa ho kenngoa ho sephara ho bula beton e nyenyane e khethehileng, eo moea o fanoang ka eona. Kahoo, hoa khoneha ho atolosa tumello ea valve, leha ho le joalo, valvuloplasty ha e kotsi hakaalo ho feta li-prosthetics tse tloaelehileng tsa valve.
