Abstract
Objective: To confirm the quality of total arterial CABG carried out using the left internal thoracic artery (LITA) and a radial artery (RA) T-graft and distal anastomoses immediately in the OR, we developed a new technique using intraoperative graft angiography. Methods: A 5-Fr sheath is inserted in the proximal radial artery stump, through which a catheter for LITA angiography is later introduced. From July 2004 to March 2005, 23 patients underwent total arterial CABG with the T-graft and intraoperative graft angiography. Results: On-pump CABG was performed in 22 patients and off-pump CABG in 1 patient. Mean procedure time for the angiography was 13.7 ± 7.3 minutes, and mean fluoroscopy time was 6.2 ± 4.6 minutes. In two patients, the RA-marginal artery side-to-side anastomosis was stenosed and had to be revised as demonstrated by graft angiography. In one patient, the RA was kinked and in another, there was a kinking of the LITA. In both cases, kinking was corrected. The remaining anastomoses were seen to have unobstructed flow with no evidence of stenosis. Conclusions: Intraoperative graft angiography can be performed in patients undergoing total arterial CABG. This concept of intraoperative cooperation between an interventional cardiologist and surgeons could significantly improve the operative outcome in CABG surgery.
