[Multivessel coronary artery bypass grafting with arterial conduits].
With increased use of catheter intervention, candidates for coronary artery bypass grafting (CABG) have become more severely diseased. In the past 4 years with normothermic cardiopulmonary bypass technique, operative mortality was 1.5% (0.7% for elective and 5.6% for emergency) in 690 primary CABGs. The internal thoracic artery graft was used in 94% of the patients and the patency rate was 98%. The gastroepiploic artery was used in 565 patients since 1986 with 2.3% operative mortality and the patency rate was 96% in early and 92% in mid-term angiography. The inferior epigastric artery was used in 48 patients with 2% operative mortality and 90% patency rate. The radial artery was used in 105 patients with 0.9% operative mortality and patency rate was 88% at 1 postoperative year. Surgical result and angiographic patency of the graft are acceptably good while candidates of CABG have become more severely diseased. With use of arterial conduits, better long term outcome can be expected.
