With the extensive use of internal thoracic artery grafts in coronary artery bypass procedures sequential anastomosis of the left internal thoracic artery LITA to LAD has gained popularity in these challenging cases. The long term results of sequential LITA to LAD anstomosis were examined in this study. Patients and Methods In order to determine the long term results of the sequential revascularization of LAD by LITA graft 41 out of 49 patients operated between January 2001 and December 2005 were selected for control coronary arteriography. The median period for control coronary arteriography was 64 months. Results Seventy five anastomoses were found to be fully patent 91 46 among the 82 sequential LITA anastomoses 41 LITA grafts on the LAD at a median follow-up period of 64 months 53 to 123 months . Among the 41 LITA grafts used for this purpose 36 were found intact complete patency of the proximal and distal anastomoses 87 8 . Two LITA grafts 4 anastomoses were found to be totally occluded 4 87 . The proximal anastomosis of the LITA graft was observed to be 90 stenotic in one patient 1 21 . In one patient tight stenosis of the distal anastomosis line was observed 1 21 while in another patient 70 narrowing of LITA lumen after the proximal anastomosis was detected 1 21 . Conclusion We strongly beleive that sequential LITA grafting of LAD is a safe alternative
