Abstract

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.
