SEQUENTIAL VERSUS SINGlE SAPHENOUS VEIN CORONARY ARTERY BYPASS GRAniHG IH MULTIVESSEL CORONARY ARTERY DISEASE

Abstract

The choice of grafting technique is crucial to. the success of coronary artery bypass grafting (CABG). To evaluate the short term outcome of sequential CABG technique, we compared the results in 25 patients with predominantly sequential grafts (group I} with 25 patients with single venous grafts (group II). All patients were symptomatic for angina before surgery and had multivessel coronary artery disease. There was no perioperative mortality. Both groups were evaluated immediately postoperative during hospital stay by haemodynamic monitoring and serial ECGs and cardiac enzymes, and after 6 months by clinical evaluation and by stress myocardial perfusion scanning (MPS}

• using Tc!9

The mean follow up period was 8.5 months (minimum 6.5,

maximum 13}. Out of the 50 patients, 7 cases showed positive results for stress MPS all of them less than 5%, 4 cases in (group I} and 3 in (group II}. All patients showed marked improvement of their EJection Fraction and anginal functional class, except one case in (group II}. Conclusion: The sequential venous CABG seems to have the same short term results of single venous CABG.
