RESUMO

BACKGROUND: Early patency of the coronary artery bypass grafting is determined mainly by surgical technique and status of coronary artery. We analyzed the early result, focusing on the relationship between postoperative angiographic findings and the patency rate. MATERIAL AND METHOD: During the period of July 1997- August 1999, 86 cases of CABG were performed and the postoperative coronary artery angiography was done in 76 cases on postoperative day 7 to assess the graft patency. RESULT: Overall graft patency was 90.2% on the angiographic finding. Factors influencing the early graft occlusion were the surgeon's experience, small coronary artery size less than 1.5mm in diameter, coronary arteries related to pre-operative myocardial infarction, and local atheroma at the anastomosis site(p<0.001). Operative mortailty was 2.3%. Early recurrence of the symptom was 19.8% during the follow up period. CONCLUSIONS: We examined the postoperative coronary angiography and found that the surgeon's experience, small coronary artery size less than 1.5mm in diameter, bypass surgery on the coronary arteries related to pre-operative myocardial infarction, and local atheroma at the anastomosis site were the factors for the graft occlusion.

RESUMO

BACKGROUND: Onlay vein patch coronary angioplasty has been known to be an option for coronary artery stenosis in the selective iesions MATERIAL AND METHOD: During the period between July 1997 and August 1999, coronary angioplasty using autologous saphenous vein was done on 16 sites in 14 cases for the stenotic lesion at the bifurcation area and significantly stenosis distal to anastomosis. RESULT: Early patency of the angioplasty site was 85.7% at postoperative day 7. There was no statistically difference in graft patency, operative parameters, and complications compared to conventional anatomosis(p>0.05). CONCLUSIONS: Despite the small number of cases, the patency rate of the coronary patch angioplasty was comparable to the conventional CABG. Coronary artery only patch angioplasty could be performed in highly selected coronary arteries.
