DETECTION OF PATENT CORONARY-BYPASS GRAFTS BY COMPUTED-TOMOGRAPHY - A PRELIMINARY-REPORT CIRCULATION Brundage, B. H., Lipton, M. J., Herfkens, R. J., BERNINGER, W. H., REDINGTON, R. W., Chatterjee, K., Carlsson, E. 1980; 61 (4): 826-831

Abstract

Twenty-three coronary bypass graft patients were evaluated by a contrast-enhanced computed tomography (CT) technique to determine graft patency. Four to six 4.8-second sequenced scans with a 1-second interscan interval were obtained in each patient during the hand injection of 25-30 ml of contrast medium in a peripheral vein. Patency of grafts was determined by a characteristic contrast enhancement. The CT technique correlated with angiographic assessment of graft patency in 59 of 62 grafts (95%). We conclude that this relatively noninvasive technique shows promise as a method for determining coronary bypass graft patency.
