Abstract

From October 1991 to April 1996, 27 patients underwent aortocoronary bypass graft. There were 17 men, 10 women. The mean age was 65 years(range 45 to 76). The preoperative clinical status were chronic stable angina in 11 cases, unstable angina in 13 cases and postinfarction angina in 3 cases. The involved risk factors were as follows: Hypertension in 7 cases, Diabetes Mellitus in 5 cases and any other diseases in 3 cases. We divided these patients into two groups in this survey: The A group was 15 patients who were managed with cardioplegia from 1991 to 1994. The B group of 12 patients was done with intermittent aortic clamping without cardioplegia from 1995 to 1996. The mean numbers of graft per patient was 2.0 in A group and 2.83 in B group. The ischemic time per graft was 27.3 minute in A group and 18.5 minute in B group respectively. The morbidity was occlusion of grafted vessel in one patient and one of postoperative angina in A group. The total mortality was 14.8%(4/27), but mortality of B group was 8.3%(1/12).
