Application of Symmetry aortic connector in off-pump coronary artery bypass grafting / 中国微创外科杂志

ABSTRACT

ObjectiveTo summarize the short-term effects o f Symmetry aortic co nnector in off-pump coronary artery bypass grafting (OPCAB) operation. MethodsTwo hundreds and four patients suffering from coronary artery d isease underwent OPCAB from September 2002 to June 2003. Among the 204 patients, saphenous vein grafts were used in 167 patients and Symmetry aortic connectors were adopted in 100 of them.ResultsOf 142 connectors used, 2 connectors fai led and manual r epairs were required in 3 cases because of anastomotic leakage, the success rate being 96 5% (137 of 142). The number of proximal anastomosis was (1 4?0 5) per case and the number of distal anastomosis (3 5?0 8) per case. The proximal a na stomotic blood flow was (46 5?22 3) ml/min. The fitting time for connectors w as (4 0?1 1) min, and anastomoses were all accomplished within 10 seconds. The op eration time was (3 2?0 4) hours. The operative death rate was 1% (1 of 100). R e-operation of thoracotomy was required in 1 case because of bleeding but not an astomotic bleeding. No myocardial infarction or stroke occurred in the peri-oper ative period. The postoperative drainage amount was (547?247) ml. The blood tra nsfusion rate was 36 0% (36 of 100). The postoperative hospital stay was (7 8 ?1 6) days.ConclusionsSymmetry aortic connector can be saf ely and effectively used in coronary artery bypass grafting operations, with satisfactory short-term clinical effects. The procedure may shorten operation time, avoid aortic clampi ng, and lower the incidence of stroke.
