Internal mammary artery collateral to the external iliac artery: an angiographic consideration prior to coronary bypass surgery.
The role of routine selective angiography of the internal mammary artery prior to myocardial revascularization is controversial. We report a patient with coronary artery disease and peripheral vascular disease in whom the left internal mammary artery supplied blood flow to the left external iliac artery via a collateral network. Thus, selective angiography of the internal mammary artery did play a major role in the proper management of this patient who required coronary bypass surgery. A major potential postoperative complication of left lower extremity ischemia may have been prevented.
