I-valve stenosis yepulmonary

I-Pulmonary valve stenosis sisifo sentliziyo esichaphazela ivelufa yemiphunga.

Le ivelufa yahlulahlula i-ventricle elungileyo (elinye lamagumbi asentliziyweni) kunye nomthambo we-pulmonary. Umthambo we-pulmonary uphatha igazi elingena-oxygen kwimiphunga.

I-Stenosis, okanye ukunciphisa, kwenzeka xa ivelufa ingakwazi ukuvula ngokwaneleyo. Ngenxa yoko, ligazi elincinci elihamba liye emiphungeni.

Ukunciphisa i-valve ye-pulmonary valve ihlala ikhona ngexesha lokuzalwa (ukuzalwa). Kubangelwa yingxaki eyenzeka njengoko umntwana ekhula esibelekweni ngaphambi kokuzalwa. Unobangela awaziwa, kodwa imizila yemfuza inokudlala indima.

Ukuxinana okwenzeka kwivelufa uqobo kubizwa ngokuba yi-pulmonary valve stenosis. Kusenokubakho nokunciphisa ngaphambi nje okanye emva kwesivalo.

Isiphene sinokwenzeka sodwa okanye nezinye iziphene zentliziyo ezikhoyo ekuzalweni. Imeko inokuba mnene okanye ibenzima.

I-Pulmonary valve stenosis sisifo esingaqhelekanga. Ngamanye amaxesha, ingxaki isebenza kwiintsapho.

Iimeko ezininzi ze-valve stenosis ye-pulmonary zincinci kwaye azibangeli zimpawu. Ingxaki ihlala ifumaneka kwiintsana xa intliziyo ikrokra xa kuvavanywa intliziyo.

Xa i-valve iyancipha (stenosis) imodareyitha kakhulu, iimpawu zibandakanya:

• Ukuqaqanjelwa sisisu
• Umbala oluhlaza okwesibhakabhaka kulusu (i-cyanosis) kwabanye abantu
• Ukutya okungafanelekanga
• Iintlungu zesifuba
• Ukufa isiqaqa
• Ukudinwa
• Ukutyeba ubunzima okanye ukusilela ukukhula kakuhle kwiintsana ezinobunzima obukhulu
• Ukuqhawukelwa ngumphefumlo
• Ukufa ngesiquphe

Iimpawu zinokuba zibi ngakumbi ngokwenza umthambo okanye umsebenzi.

Umboneleli wezempilo unokuva ukumbombozela kwentliziyo xa umamele intliziyo usebenzisa i-stethoscope. Izikhalazo zivuthela, zitshitshisa, okanye zivakala izandi eziviweyo ngexesha lokubetha kwentliziyo.

Iimvavanyo ezisetyenziselwa ukufumanisa i-pulmonary stenosis zingabandakanya:

• Ukucinywa kwentliziyo
• I-x-ray yesifuba
• ECG
• Echocardiogram
• I-MRI yentliziyo

Umboneleli uya kubala ubungakanani be-valve stenosis ukucwangcisa unyango.

Ngamanye amaxesha, unyango alunakufuneka ukuba ingxaki iphantsi.

Xa kukho ezinye iziphene zentliziyo, amayeza anokusetyenziselwa:

• Nceda igazi lihambe ngentliziyo (prostaglandins)
• Nceda intliziyo ibethe ngamandla
• Thintela amahlwili (abacoci begazi)
• Susa ulwelo olugqithisileyo (iipilisi zamanzi)
• Phatha ukubetha kwentliziyo okungaqhelekanga kunye nesingqisho

Iibhaluni ze-pulutary pulmonary dilation (i-valvuloplasty) inokwenziwa xa kungekho ezinye iziphene zentliziyo ezikhoyo.

• Le nkqubo yenziwa ngemithambo yegreyidi.
• Ugqirha uthumela ityhubhu eguqukayo (i-catheter) enebhaluni encanyathiselwe esiphelweni ukuya entliziyweni. I-x-reyi ezikhethekileyo zisetyenziselwa ukunceda ukukhokela i-catheter.
• Ibhaluni yolula ukuvulwa kwevalve.

Abanye abantu banokufuna uqhaqho lwentliziyo ukulungisa okanye ukubuyisela i-valve yamaphaphu. Ivalve entsha inokwenziwa ngezinto ezahlukeneyo. Ukuba ivelufa ayinakulungiswa okanye itshintshwe, kunokufuneka ezinye iinkqubo.

Abantu abanesifo esiphantsi kunqabile ukuba mandundu. Nangona kunjalo, abo banesifo esilinganayo ukuya esiqatha baya kusiba mandundu. Isiphumo sihlala sihle kakhulu xa utyando okanye i-balloon dilation iphumelele. Ezinye iziphene zentliziyo yokuzalwa zinokubangela imbonakalo.

Rhoqo, izivalo ezintsha zinokuhlala amashumi eminyaka. Nangona kunjalo, ezinye ziya kudinwa kwaye zifuna ukutshintshwa.

Iingxaki zinokubandakanya:

• Ukubetha kwentliziyo okungaqhelekanga (arrhythmias)
• Ukufa
• Ukusilela kwentliziyo kunye nokwandiswa kwecala lasekunene lentliziyo
• Ukuvuza kwegazi kubuyele kwi-ventricle efanelekileyo (ukuphinda ubuye) kwakhona emva kokulungiswa

Fowunela umnikezeli wakho ukuba:

• Unempawu ze-valve stenosis ye-pulmonary.
• Unyangiwe okanye une-pulmonary valve stenosis engaphendulwanga kwaye uphuhlise ukudumba (kwamaqatha, imilenze, okanye isisu), ubunzima bokuphefumla, okanye ezinye iimpawu ezintsha.
