I-DCA, okanye isikhokelo se-coronary atherectomy yinkqubo encinci yokungenelela yokususa ukubhloka kwimithambo yegazi ukuphucula ukuhamba kwegazi kwintliziyo kunye nokunciphisa iintlungu.

Okokuqala, i-anesthesia yendawo iphazamisa indawo ye-groin. Emva koko ugqirha ubeka inaliti kumthambo wobufazi, umthambo obaleka umlenze. Ugqirha ufaka ucingo olukhokelayo ngenaliti emva koko asuse inaliti. Uyifaka endaweni yayo ngesingenisi, isixhobo esisemzimbeni esinamazibuko amabini esisetyenziselwa ukufaka izixhobo eziguqukayo ezinje ngecatheter kwisitya segazi. Nje ukuba isingenisi sibekhona, isikhombisi sokuqala sothathelwa indawo ngocingo oluhle. Olu cingo lutsha lusetyenziselwa ukufakela i-catheter yokuqonda isifo, ityhubhu ende eguqukayo, emthanjeni kwaye uyikhokelele entliziyweni. Ugqirha ke ususa ucingo lwesibini.

Ngokusebenzisa ipayinti xa kuvulwa enye yemithambo yegazi, ugqirha utofa idayi kwaye uthatha iX-reyi. Ukuba ibonisa ukucinywa okunganyangekiyo, ugqirha usebenzisa enye ucingo yesikhokelo ukususa i-catheter yokuqala kwaye ayitshintshe nge-catheter ekhokelayo. Ke ucingo olwalusetyenziselwa ukwenza oku luyasuswa kwaye endaweni yalo kufakwe ucingo olucolekileyo oluqhubele phambili kuthintelo.

Enye itafile eyenzelwe ukusika izilonda ikwadlula kwindawo yokuvalela. Ibhaluni yoxinzelelo oluphantsi eqhotyoshelwe ecaleni komsiki, inomoya, iveza izinto zezilonda kumsiki.

Iyunithi yokuqhuba ivuliwe, ibangela ukuba umsiki ajikeleze. Ugqirha uqhubela phambili i-lever kwiyunithi yokuqhuba ethi yona ihambele phambili kumsiki. Iziqwenga zokuvaleka ezisikayo zigcinwa kwicandelo le-catheter ebizwa ngokuba yimpumlo de zisuswe ekupheleni kwenkqubo.

Ukujikeleza i-catheter ngelixa usenza i-inflating kunye nokuhlutha ibhaluni kwenza ukuba kunokwenzeka ukusika ukuvaleka kulo naliphi na icala, okukhokelela kwi-debulking efanayo. I-stent inokufakwa kwakhona. Esi sisixhobo sesinyithi esibekiweyo esifakwe ngaphakathi kwimithambo yegazi yokugcina inqanawa ivulekile.

Emva kwenkqubo, ugqirha utofa idayi kwaye uthathe iX-reyi ukujonga utshintsho kwimithambo. Emva koko i-catheter isuswe kwaye inkqubo iphelile.
