La mthokozisi Isivivinyo esivumela ukuthi ubone ngeso lengqondo i- imithambo yegazi, okungukuthi, imithambo eletha igazi enhliziyweni.

Le X-ray yemithambo yenhliziyo yenza kube nokwenzeka ngokukhethekileyo ukuqinisekisa ukuthi ayincishisiwe noma ivinjwe ama-plaqueatherosclerosis.

I-coronary CT scan noma mthokozisi futhi ikuvumela ukuba ubone ngeso lengqondo imithambo yenhliziyo, kepha ngendlela engatheleli kangako kune-coronary angiography (lokhu kudinga ukubhoboza umthambo, kuyilapho isithwebuli sidinga kuphela ukuthanjiswa komthambo ukujova umkhiqizo ohlukile).

I-Coronary angiography ihlala ingukuhlolwa okuyinkomba ukubona ngeso lengqondo imithambo yenhliziyo nokubona noma yikuphi ukuncipha (= ukuqina) okungathinta ukugeleza kwegazi kuye enhliziyweni. Lezi zingqinamba zingabhekana ne-angina, ukwehluleka kwenhliziyo kanye ne-infarction ye-myocardial. Yenziwa kaningi kuneCoroscanner, egcinelwe amacala athile athile.

Izinkomba ze-coronary angiography ikakhulukazi:

• Ukuba khona kobuhlungu esifubeni, okwenzeka ikakhulukazi ngesikhathi sokuzivocavoca (ukuhlolwa okuphuthumayo noma okuhleliwe)
• ukulawula nokuqapha ukuhlinzwa ngokudlula kwenhliziyo sekuvele kusethiwe
• ukwenza ukuhlolwa kwangaphambi kokuhlinzwa uma kwenzeka i-valvulopathie (= isifo senhliziyo) kwezinye iziguli
• ukubheka ukukhubazeka kokuzalwa (kokuzalwa) kwemithambo yenhliziyo.

I-Coronary angiography wukuhlolwa okuhlaselayo okudinga ukubhoboza umthambo ngomjovo womkhiqizo ohlukile we-iodine, opaque kuma-X-ray. Ngokwenzayo, udokotela ufaka ipayipi elincane emgodleni (umthambo wesifazane) noma esihlakaleni (umthambo oshisa imithambo) ngemuva kwe-anesthesia yendawo bese “eyiphusha” emlonyeni wemithambo yenhliziyo engakwesokudla nangakwesobunxele, ukujova umkhiqizo lapho igumbi le-radiology.

Umshini ube usuthatha uchungechunge lwezithombe, kanti isiguli sihlala silele phansi. I-Coronary angiography ngokuvamile idinga ukuhlala amahora angama-24 kuye kwangama-48 esibhedlela, yize ukufakwa emthanjeni osizayo kuvumela ukuphuma kwesiguli ngokushesha.

Umuntu ulele phansi, futhi umshini we-x-ray noma isithwebuli sithatha uchungechunge lwezithombe ngemuva kokujova okufana nokuqhathanisa. Lesi sigaba asibuhlungu futhi siyashesha.

Ukuhlolwa kwenza kube nokwenzeka ukugqamisa noma yikuphi ukuncishiswa noma ukuvinjelwa kwemithambo ye-coronary. Kuye ngezinga lokuncipha kanye nezimpawu zesiguli, ithimba lezokwelapha lingase linqume ukwenza ukwelashwa ngesikhathi esifanayo ne-coronary angiography, ukuze kugwenywe ukuphinda kulaliswe esibhedlela.

Kunezinketho eziningi ezikhona:

• theangioplasty : okubandakanya ukukhulisa umthambo ovinjiwe usebenzisa ibhaluni elifuthwayo, noma ungafaki i-prosthesis (= stent, uhlobo oluthile lwenetha elincane eligcina umthambo uvulekile)
• le i-bypass (okuhlanganisa ukujikeleza kwegazi ngokugwema umthambo ovalekile)
