Purpose : To analyse the contributing factors for early graft obstruction anastomosed to small coronary artery after coronary artery bypass graft (CABG)
Methods : From October 2010 to July 2017, elective, isolated CABG was 754 cases. Nonelective operation and complex surgery was excluded and target coronary arteries were less than 1.5 mm in 191 cases. Immediate postoperative and 6 months follow coronary CT were done in 122 cases and retrospective analysis for various perioperative factors and follow up data was done.
Results : There was no 30-day mortality. The average number of anastomosis was 2.81. Total number of anastomosis to small coronary artery were 151. 44 left anterior descending artery, 13 diagonal artery and ramus intermedius, 43 left circumplex artery branches and 56 right coronary artery branches. Of 151 anastomosis, grafts were not invisible in immediate postoperative coronary CT in 18 anastomosis(11.9%). The obstruction rates of each graft were : left internal thoracic artery 1.6%, radial artery 5.9%, saphenous vein 8.4%. Anastomosis to right coronary artery (p=.000) and use of saphenous vein graft (p=.022) were statistically significant factors of early graft occlusion. Anastomosis to right coronary artery( p=.000) and use of saphenos vein graft (p=.011) also statistically important factors for 6 months follow up coronary CT. Repeated revascularization after discharge were 3 cases and 3 cases of mortalities were observed during follow up.
Conclusion : Anastomosis to right coronary artery and use of saphenous vein were significant factors for early graft occlusion. Long term results and survival should be followed
