OBJECTIVE: To evaluate the features of coronary artery bypass reoperations and to reduce the influence of the factors affecting postoperative morbidity and mortality. MATERIAL AND METHODS: The records of 53 consecutive @entity1 (88.7% of @entity1 , 11.3% of @entity1 ; mean age 67.1+/-7.5 years) who underwent coronary artery bypass reoperations were reviewed retrospectively. Coronary artery bypass reoperations comprised 2.98% of all coronary artery bypass grafting operations during that period. Coronary artery bypass reoperations performed within 4-week period after the last operation and complex procedures were excluded. RESULTS: Postoperative mortality after 53 reoperations and 1775 primary coronary artery bypass grafting operations was 7.5 and 2.52%, respectively, and the results are comparable with the results from other clinics of cardiac surgery. Mean time interval between primary coronary artery bypass grafting and reoperation was 90.7+/-49.9 months. Angiography at that period showed patency of venous and arterial conduits--34.6 and 76.5%, respectively. Twenty-nine @entity1 (54.7%) received only venous conduits during reoperation. There were 2.4+/-1.1 anastomoses constructed during reoperation comparing to 3.5+/-0.9 anastomoses per @entity1 during primary coronary artery bypass grafting. CONCLUSIONS: According to our data mortality after coronary reoperations remains higher comparing to primary coronary artery bypass grafting, however, it does not differ significantly. We observed an increasing number of elderly @entity1 in coronary reoperations. We think that it is related to the demographical changes within our country and increased use of arterial conduits during primary coronary artery bypass grafting operations. Arterial conduits are patent at least 10 years; it means that the time period until recurrent @entity951 and reoperation is delayed. However, progression of @entity731 remains the main reason for coronary artery bypass grafting reoperation.
