Abstract

GOMES, Walter J.; PAEZ, Rodrigo P.  and  ALVES, Francisco A.. Coronary artery bypass surgery in patients with anomalous circumflex artery. Arq. Bras. Cardiol. [online]. 2007, vol.88, n.4, pp. e76-e78. ISSN 0066-782X.  http://dx.doi.org/10.1590/S0066-782X2007000400024.

The anomalous origin of the circumflex artery (Cx) is uncommon and presents course variations that might make the coronary artery bypass surgery (CABG) difficult. Two patients presenting unstable angina were submitted to coronary angiography that disclosed tri-vessel disease and presence of Cx with an anomalous origin and retroaortic course with severe stenosis. Both patients underwent CABG with use of bilateral internal thoracic artery (ITA) grafts. Therefore, CABG with bilateral ITA use is feasible in cases of an anomalous origin of the Cx artery. However, this finding may constitute an additional technical setback.

Keywords : Internal mammary-coronary artery anastomosis; coronary artery bypass; coronary arteriosclerosis; myocardial revascularization; mammary arteries.
