Background-Complete arterial CABG is a surgical option to improve long-term results in the treatment of coronary artery disease (CAD). Harvesting of multiple arterial grafts is commonly associated with prolonged operating times and increased trauma. By use of new operative techniques (skeletonized grafts and the T-graft approach), CABG in multivessel CAD is now possible with only 2 grafts. We present our experience in the use of these techniques on a routine basis. Methods and Results-Between March 1996 and September 1999, 490 patients (aged 61Ϯ9 years, 20% female) underwent complete arterial CABG. Left ventricular ejection fraction ranged from 15% to 85% (mean 59Ϯ15%). Triple-vessel disease was present in 88% of the patients. The incidence of diabetes mellitus was 32% (14% insulin dependent). Either both internal thoracic arteries (ITAs) (23%) or the left ITA and radial artery (77%) were used as conduits. In 85% of the patients, a T graft was created. Mean operating time was 198Ϯ46 minutes; bypass time, 82Ϯ25 minutes; and ischemic time, 58Ϯ22 minutes. Two to 7 (mean 4.1Ϯ0.9) anastomoses were performed per patient. Perioperative intra-aortic balloon pump was necessary in 12 patients (2.4%). The rate of perioperative myocardial infarction was 1.2%. Sternal complications occurred in 1.0%, and in-hospital mortality was 2.2%. Postoperative coronary angiography in 172 patients (35%) documented excellent patency rates (left ITA 98.3%, right ITA 96.5%, and radial artery 96.6%). Conclusions-Complete

Background —Complete arterial CABG is a surgical option to improve long-term results in the treatment of coronary artery disease (CAD). Harvesting of multiple arterial grafts is commonly associated with prolonged operating times and increased trauma. By use of new operative techniques (skeletonized grafts and the T-graft approach), CABG in multivessel CAD is now possible with only 2 grafts. We present our experience in the use of these techniques on a routine basis. Methods and Results —Between March 1996 and September 1999, 490 patients (aged 61±9 years, 20% female) underwent complete arterial CABG. Left ventricular ejection fraction ranged from 15% to 85% (mean 59±15%). Triple-vessel disease was present in 88% of the patients. The incidence of diabetes mellitus was 32% (14% insulin dependent). Either both internal thoracic arteries (ITAs) (23%) or the left ITA and radial artery (77%) were used as conduits. In 85% of the patients, a T graft was created.

Perioperative intra-aortic balloon pump was necessary in 12 patients (2.4%). The rate of perioperative myocardial infarction was 1.2%. Sternal complications occurred in 1.0%, and in-hospital mortality was 2.2%. Postoperative coronary angiography in 172 patients (35%) documented excellent patency rates (left ITA 98.3%, right ITA 96.5%, and radial artery 96.6%). Conclusions —Complete arterial revascularization in multivessel CAD is possible with the use of only 2 grafts with good perioperative results. This approach allows for complete arterial CABG on a routine basis.
