I-pulmonary valve stenosis

I-pulmonary valve stenosis yisifo senhliziyo esifaka i-valve yamaphaphu.

Le yi-valve ehlukanisa i-ventricle efanele (elinye lamagumbi asenhliziyweni) nomthambo wamaphaphu. Umthambo wamaphaphu uhambisa igazi elingenayo i-oxygen emaphashini.

I-stenosis, noma ukunciphisa, kwenzeka lapho i-valve ingakwazi ukuvula ngokwanele. Ngenxa yalokho, igazi elincane ligelezela emaphashini.

Ukuncipha kwe-valve ye-pulmonary kuvame ukubakhona ngesikhathi sokuzalwa (kokuzalwa). Kubangelwa inkinga eyenzeka njengoba ingane ikhula esibelethweni ngaphambi kokuzalwa. Imbangela ayaziwa, kepha izakhi zofuzo zingadlala indima.

Ukuncipha okwenzeka ku-valve uqobo kubizwa nge-pulmonary valve stenosis. Kungase kube nokuncipha ngaphambi nje noma ngemuva kwe-valve.

Isici singavela sodwa noma sinezinye izinkinga zenhliziyo ezikhona lapho kuzalwa. Isimo singaba mnene noma sibe nzima.

I-pulmonary valve stenosis yisifo esingajwayelekile. Kwezinye izimo, inkinga isebenza emindenini.

Izimo eziningi ze-valve stenosis yamaphaphu zincane futhi azibangeli zimpawu. Inkinga ivame ukutholakala ezinganeni lapho kuzwakala ukukhononda kwenhliziyo ngesikhathi sokuhlolwa kwenhliziyo okujwayelekile.

Lapho i-valve narrowing (stenosis) ilinganiselwa kokubi, izimpawu zifaka:

• Ukuhlukaniswa kwesisu
• Umbala we-Bluish esikhumbeni (i-cyanosis) kwabanye abantu
• Ukudla okungekuhle
• Ubuhlungu besifuba
• Ukuquleka
• Ukukhathala
• Ukuzuza kwesisindo esingesihle noma ukwehluleka ukuchuma ezinganeni ezinokukhubazeka okukhulu
• Ukuphelelwa umoya
• Ukufa okungazelelwe

Izimpawu zingase zibe zimbi kakhulu ngokuzivocavoca noma ngokwenza.

Umhlinzeki wezokunakekelwa kwempilo angakuzwa ukukhononda kwenhliziyo lapho elalele inhliziyo esebenzisa i-stethoscope. Ukububula kuyaqhuma, kuqhume, noma kuzwakale imisindo ezwakala ngesikhathi sokushaya kwenhliziyo.

Ukuhlolwa okusetshenziselwa ukuxilonga i-pulmonary stenosis kungafaka:

• I-catheterization yenhliziyo
• I-x-ray yesifuba
• ECG
• I-Echocardiogram
• I-MRI yenhliziyo

Umhlinzeki uzobeka ubucayi be-valve stenosis ukuhlela ukwelashwa.

Kwesinye isikhathi, ukwelashwa kungahle kungadingeki uma ukugula kumnene.

Uma kukhona nokunye ukukhubazeka kwenhliziyo, imithi ingasetshenziselwa:

• Siza ukugeleza kwegazi kudlule enhliziyweni (i-prostaglandins)
• Siza inhliziyo ishaye ngamandla
• Vimbela amahlule (abanciphisi begazi)
• Susa uketshezi oluningi (amaphilisi amanzi)
• Phatha ukushaya kwenhliziyo okungajwayelekile kanye nezigqi

Amabhaluni we-perututional pulmonary dilation (i-valvuloplasty) angenziwa lapho kungekho ezinye izinkinga zenhliziyo ezikhona.

• Le nqubo yenziwa ngomthambo osemgodini.
• Udokotela uthumela ishubhu eliguquguqukayo (ipayipi) elinebhaluni elinamathiselwe ekugcineni kuze kufike enhliziyweni. Ama-x-ray akhethekile asetshenziselwa ukusiza ukuqondisa i-catheter.
• Ibhaluni lelula ukuvulwa kwe-valve.

Abanye abantu bangadinga ukuhlinzwa kwenhliziyo ukulungisa noma ukufaka esikhundleni i-valve yamaphaphu. I-valve entsha ingenziwa ngezinto ezahlukene. Uma i-valve ingalungiseki noma ishintshwe, kungadingeka ezinye izinqubo.

Abantu abanesifo esincane abavamile ukuba babi kakhulu. Kodwa-ke, labo abanezifo ezilinganiselwe kuya kwezinzima bazoba kubi kakhulu. Umphumela uvame ukuba muhle kakhulu lapho ukuhlinzwa noma i-balloon dilation kuphumelela. Okunye ukukhubazeka kwenhliziyo okuzalwa nakho kungaba yisici ekubukekeni.

Imvamisa, ama-valve amasha angahlala amashumi eminyaka. Noma kunjalo, ezinye zizoguga futhi zidinga ukushintshwa.

Izinkinga zingafaka:

• Ukushaya kwenhliziyo okungavamile (arrhythmias)
• Ukufa
• Ukwehluleka kwenhliziyo nokwandiswa kohlangothi lwangakwesokudla lwenhliziyo
• Ukuvuza kwegazi kubuyele ku-ventricle efanele (ukubuyiswa kwamaphaphu) ngemuva kokulungiswa

Shayela umhlinzeki wakho uma:

• Unezimpawu ze-valve stenosis yamaphaphu.
• Uphathwe noma une-valve stenosis engalashwa futhi uye wakhula ukuvuvukala (kwamaqakala, imilenze, noma isisu), ukuphefumula kanzima, noma ezinye izimpawu ezintsha.
