The authors analyzed the results of aortocoronary bypass surgery in correlation with the condition of the shunts and the native blood vessels. According to this analysis, 92.9% of the shunts were passable within 7.2 +/- 0.8 months of the surgery. Twelve shunts (four arterial and eight venous ones) had been occluded by the time of the control examination. Another ten shunts (five arterial and five venous ones) had hemodynamically significant stenoses. Concurrent blood flow was revealed in eight patients. According to comparative analysis, in cases of arterial shunting a good condition of the shunts was found in 95.6% of cases, while in patients with venous shunts the shunts were in a good condition in 88.1% of cases. Depending on the type of connection, the passability was satisfactory in 91.2% of straight shunts, in 94.5% of sequential shunts, and in 71.4% of Y-shaped ones. Analysis of changes in the native coronary arteries revealed progression of atherosclerosis in the bypassed arteries proximally to the site of anastomosis in 27 (25.5%) patients. An increase in the degree of stenosis distally of the site of anastomosis was found in 8 (7.5%) of patients; in another 7 (6.6%) patients similar changes were revealed in non-bypassed arteries. The surgery led to the disappearance of anginous manifestations and a negative result of a physical load test in most patients. |
