[Evaluation of the permeability of aortocoronary bypass by digital angiography].
Evaluation of coronary artery bypass graft patency by intra-arterial digital subtraction angiography was performed in 201 patients. A first group of 150 asymptomatic patients was systematically evaluated for post-operative screening 8.5 days after surgery as an immediate check on surgical results. Grafts were found occluded in 2.3%. A second group of 51 patients complaining of recurrent angina was studied 10 months (range 2 months to 9 years) after operation. Angiography revealed that 90% of grafts were patent but 8 grafts stenoses were diagnosed. In both groups, opacification of the run-off was achieved in 83%, but the quality of opacification was very low.
