Abstract

The patency of graft vessels and their effects on the native coronary circulation were studied by evaluation of 78 graft sites in 35 patients who underwent selective bypass graft angiography among 152 CABG cases at a mean follow-up 12.6 month.
The result were as follows ;
1) The overall graft patency rate was 70.5% : 73.8% for left anterior descending artery, 68.4% for left circumflex arterty, 64.7% for right coronary artery.
2) The patency rate of internal mammary artery was 77.8%.
3) In twenty eight patients who underwent native coronary angiography, twelve pateints showed progression of coronary artery disease in grafted vessel and two patients showed progression of coronary artery disease in non-grafted vessel.
4) The treadmill test was performed before and after coronary artery bypass graft in thirteen patients. Among 13 patients, nine patinets showed improved exercise tolerance.
5) The percutaneous transluminal coronary angioplasty were successfully performed for dilating three cases of stenotic vein graft and two cases of left main lesions after CABG and one case of stenotic left internal mammary artery graft.
