CT Demonstration of the Extracardiac Anastomoses of the Coronary Veins in Superior Vena Cava or Left Brachiocephalic Vein Obstruction
A 70 year old male with acute chest pain underwent a CT angiogram for suspected PE. The scan showed evidence of remote aortocoronary bypass and surgical ligation of the LBCV. Only the upper half of the LBCV was opacified by IV contrast. No evidence of PE was found.
