Abstract:
12 months in 31.3% (15/48). The graft lesions were found in 72.9% (35/48) of the patients, the worsened native lesions in 8.3% (4/48) and incomplete revascularization in 12.5% (6/48). Total occlusion was found in 33.3% (45/135) of the grafts and stenosis in 5.9% (8/135). LIMA total occlusion was 46.4% (13/28), stenosis was 8.6% (3/35) and competitive flow was 8.6% (3/35). Stenosis was found in 5.2% (5/97) of the SVG and total occlusion in 35.1% (34/97). Two of the five radial arteries were stenotic. Except for the chronic total occlusions, PCI treated the above problems with a high success rate. Conclusion Reoccurrence of angina is not uncommon after CABG. The causes are mainly due to the graft problem, and secondly due to worsened native lesion and incomplete revascularization. PCI can be used to treat the above problems except for the chronic total occlusions of the native vessels and graft.
