I-PTCA, okanye i-percutaneous transluminal coronary angioplasty, yinkqubo encinci engenayo evula imithambo ye-coronary evaliweyo yokuphucula ukuhamba kwegazi kwinyama yentliziyo.

Okokuqala, i-anesthesia yendawo iphazamisa indawo ye-groin. Emva koko, ugqirha ubeka inaliti kumthambo wobufazi, umthambo obaleka umlenze. Ugqirha ufaka ucingo olukhokelayo ngenaliti, alususe inaliti, alufake kwazisa, isixhobo esinamazibuko amabini okufaka izixhobo eziguqukayo. Emva koko ucingo lwesikhokelo sokuqala lubuyiselwe ngocingo olucekeceke. Ugqirha udlulisa ityhubhu ende emxinwa ebizwa ngokuba yi-catheter yokuqonda isifo phezu kocingo olutsha, ngesingenisi, nakwi-artery.Nje ukuba kungene, ugqirha uyikhokelela kwi-aorta kwaye asuse ucingo lwesikhokelo.

Nge-catheter ekuvulekeni komthambo we-coronary, ugqirha utofa idayi kwaye uthathe i-X-ray.

Ukuba ibonisa ukuvaleka okunganyangekiyo, ugqirha uyayixhasa catheter ayikhuphe nge-catheter ekhokelayo, ngaphambi kokususa ucingo.

Ucingo olucekeceke lufakwa kwaye lukhokelwe ngapha kokuvaleka. I-catheter yebhaluni emva koko ikhokelwa kwindawo yokuvalela. Ibhaluni inyuselwe imizuzwana embalwa ukucinezela ukubhloka kudonga lwemithambo. Emva koko ichithwe. Ugqirha unokufaka ibhaluni amatyeli aliqela, ixesha ngalinye eligcwalisa kancinci ukuyandisa indlela.

Oku kunokuphindwa kwindawo nganye evaliweyo okanye emxinwa.

Ugqirha unokubeka i-stent, istaffold yentsimbi evaliweyo, ngaphakathi kwimithambo yegazi ukuyigcina ivulekile.

Nje ukuba uxinzelelo lwenziwe, idayi iyajongwa kwaye kuthathwa iX-reyi ukujonga utshintsho kwimithambo.

Emva koko i-catheter iyasuswa kwaye inkqubo igqityiwe.
