Umthambo we-pulmonary stenosis ubhekisela esibhedlela senhliziyo, okudinga usizo lokuhlinzeka. Ngenxa yokunciphisa umthambo we-pulmonary, ukuphuma kwegazi kusuka kwe-ventricle efanele yenhliziyo emaphashini kunzima, ngakho-ke kunengozi enkulu ye- infarction ye-myocardial .
Izimpawu ze-arterium artery stenosis
Ukuba khona kwezimpawu kuxhomeke ekutheni lesi sifo sisho kanjani. Kwenzeka ukuthi lesi sibonakaliso asiqapheli nhlobo, futhi lowo muntu akasoze asolise ngokugula kwakhe. I-stenosis ejwayelekile yomthambo we-pulmonary elicaleni eliveziwe ibonakala kanje:
- ukuphefumula okuncane nokusebenza okuncane okungokwenyama;
- ubuhlungu esifubeni ngesikhathi sokuvivinya umzimba;
- ukukhathala okusheshayo;
- i-cyanosis;
- ubumnyama emehlweni, buthaka;
- isiyezi.
Ngokuya ngohlobo lwe-stenosis, ukwehluleka kokusebenza kwe-ventricular kungase kwenzeke, kuhlukanisa i-hypoplasia, isisindo esingavamile esithinta imfucuza ephazamisa ukukhululwa kwegazi kusuka kwe-ventricle efanele yenhliziyo.
Ukwelashwa kwe-pulmonary artery stenosis
Ukuphuthuma kokusebenza kuxhomeke, okokuqala, esimweni sesiguli, nasezibikezelweni zomsebenzi oqhubekayo wenhliziyo. Uma ingozi ye-infarct ikhona, ukusebenza kwenziwa ngokushesha.
Ukukhubazeka kwenhliziyo okubangelwa yi-congenital, ngokungafani nalabo abazitholile, akunamathuba okuba abe yingozi kakhulu kubantu. Futhi i-stenosis engavamile yombuthano we-pulmonary cishe amacala angu-12% azalwa ngokuzalwa. Kodwa-ke, kunabantwana abanesifo esiphansi sesifo futhi abaqhubekela phambili empilweni yabo yonke. Abantu abanjalo baphile ngokuthula ngaphandle kwesidingo sokusebenza.
Ukuvimbela izifo
Isisu somlomo we-pulmonary umlomo sidinga isiguli ukuba sithobele izidingo ezikhethekile zokudla kanye nenani lokucindezeleka
Ngokuqondene nokuvinjelwa kwesisu somzimba we-pulmonary artery, konke kuxhomeke kulo wesifazane ozoba nomntwana. Ukuze ugweme ukuthuthukiswa kwengozi yokukhubazeka kwengane, umama olindelekile kumele aphathe ukugula kwakhe ngesikhathi, ukuqapha isimo somzimba. Kuyinto efiselekayo ezinyangeni ezimbalwa ngaphambi kokuhlolwa kokunciphisa ukukhulelwa komzimba okuhleliwe. Ukuthatha utshwala nokubhema nakho kunomthelela omubi emntwaneni. Ngoba le mikhuba kufanele ishiywe isikhathi eside ngaphambi kokukhulelwa.
