We evaluated the preeminence of the construction of proximal anastomoses during single aortic cross-clamping periods in coronary artery bypass surgery. Twenty-six patients were divided into two groups; single aortic cross-clamping (SAX) group: 13 patients, partial aortic clamping (PAC) group: 13 patients. In this study, these two groups were compared in terms of aortic cross-clamping time (AXT), total extracorporeal circulation (ECC) time (TECCT), ECC weaning time (WT), amount of cardioplegic solution, total levels of serum CPK and CPK-MB, and graft patency. The results were analyzed by ANOVA and chi-square test. AXT was longer in the SAX group compared with the PAC group (78.2 +/- 5 versus 63.2 +/- 4 min; p < 0.05). TECCT (120.4 +/- 6 versus 109 +/- 5 min) and WT (37.4 +/- 2 versus 41 +/- 2 min) were not significant between the two groups. The total amount of cardioplegic solution was greater in the SAX group compared with the PAC group (1100 +/- 60 versus 927 +/- 43 ml; p < 0.05). The levels of serum CPK and CPK-MB were a little lower in the SAX group, but there were no significant differences between the SAX group and the PCA group. The graft patency of both two groups were excellent. From these results, SAX is not critical in the routine of coronary artery bypass surgery. Clinically, the SAX technique allows us to select more suitable areas of the ascending aorta for placement of all the proximal grafts if the ascending aorta is short.(ABSTRACT TRUNCATED AT 250 WORDS)
