We evaluated the efficacy of sternal coaptation pins used to improve the fixation of the transected sternum after coronary artery bypass grafting（CABG）with the internal thoracic artery（ITA). The subjects were 37 patients who underwent scheduled single CABG with ITA in our department and they were classified into two groups, i. e., Group A, without sternal pins（18 patients), and Group B, with sternal pins（19 patients). The efficacy was assessed by the following measurements:drain bleeding volume up to 12 and 24 h after ICU admission, the time until the removal of drain, surgical site infection（SSI）and the maximum split level between the sternal body and manubrium after surgery. Drain bleeding volume up to 12 and 24 h after ICU tended to be less in Group B. The time until the removal of drain was significantly shorter in Group B. SSI was 17% in Group A but 0% in Group B. The use of sternal coaptation pins reduced misalignment of the coapted sternum, and we belive that the use of sternal coaptation pins contributed to the early removal of drain, and SSI reduction.
