ABSTRACT
A simple maneuver in intraarterial digital subtraction angiography (DSA) is proposed to improve the images of left internal thoracic artery bypass grafts (LITAGs). A contrast flush in the left subclavian artery, using a catheter that had been percutaneously introduced from the left brachial artery, was carried out in 14 patients with multiple coronary-aorta bypass grafts (CABGs) after aortic DSA. The side-hole portion of the catheter tip was positioned in the proximal left subclavian artery as the coiled portion remained in the aortic arch. Nonionic contrast medium (350 mg/ml of iodine) was injected with an automatic injector in a volume of 6-8 ml and at a flow rate of 3-4 ml/sec. Left subclavian arterial flush DSA delineated the LITAGs excellently in 11, well in 3, and fairly or poorly in none of the 14 cases. There were no complications in any of these cases. A supplemental contrast flush of the left subclavian artery with a pigtail catheter following aortic DSA improves the diagnosis of multiple CABG patency.
