Abstract:
In our department, we perform CABG operations using arterial grafts as much as possible, and in the present study, we investigated 96 patients who underwent CABG operations using arterial grafts alone during the 4-year period from October 1988 to August 1992. The sex ratio (M/F) was 64/32, and the mean age was 63.2 years. Of those 56 patients underwent bypass surgery for one artery each, using a total of 56 grafts. In 18 cases of bypass surgery for 2 arteries 34 grafts were used for 36 arteries, and in 16 patients who underwent surgery for 3 arteries, 42 grafts were used for 48 arteries. In 6 patients who underwent bypass surgery for 4 arteries, 16 grafts were used for 24 arteries. All 148 arteries harvested from 96 patients were available. Forty-one RITAs were used for 43 arteries, 68 LITAs for 72 arteries and 39 RGEAs for 49 arteries. There were 2 (2.0%) operative deaths. Among 135 grafts for 146 arteries on which arteriography was performed after operation, 133 grafts (98.6%) among 142 arteries (97.3%) were patent. In detail, the patency rate of ITA was 98 of 100 grafts (98.0%) and 102 of 105 arteries (97.1%), that of RGEA was 35 of 35 grafts (100%) and 40 of 41 arteries (97.6%), and therefore, good patency was observed in both ITA and RGEA.
