Abstract

An analysis of 17 dynamic computed tomographic studies for noninvasive visualisation of 53 aortocoronary bypass venous grafts is presented. Computed tomographic scan forms an excellent modality for visualisation of these grafts using a noninvasive technique. It was most consistent in demonstration of the right group of grafts (100%). Twenty out of 23 (86.5%) left group of grafts and 13 out of 18 (72.2%) belonging to the posterior group could be visualised. The grafts were seen as enhancing dots or streaks at characteristic locations. Meticulous care regarding bolus injection of contrast; understanding the pattern of enhancement of the structures identified as grafts; avoiding artefacts from metallic clips and prior knowledge of the number and position of grafts placed are essential for proper interpretation of the scan. A scan in the immediate postoperative period would form an excellent baseline study.
