| Abstract | ||||
| Background: Coronary artery bypass grafting (CABG) surgery is proved to treat signs and symptoms of ischemia of the myocardium. The left internal mammary artery (LIMA) is the gold standard conduit with a high patency rate reaching 90% at 10 years. Compared to 50% to 70% of saphenous vein (SV) grafts patency. A novel no touch (NT) technique in SV harvesting with its surrounding tissue is proposed as an alternative option. Studies proposed that the NT harvesting could improve patency rate post operatively. However, more evidence is needed for the generalizability of this novel technique. Aim: To compare between conventional vein harvesting and no touch technique regarding patency at a period of 6 months. Subject and Methods: A total of 52 patients underwent saphenous vein graft harvesting for coronary artery bypass grafting at Kobri ELKobba, 26 patients were done using the conventional method and 26 with No touch technique. Results: 52 participants had multi-slice computed tomography on coronary vessels (MSCT) at 6 months after surgery. The NT group showed significant lower rates of vein graft occlusion compared to the conventional group at 6 months (11.5% of patients who underwent conventional method in contrast to 3.8% whom underwent vein harvesting via no touch technique p<0.043). Conclusion: In comparison with the conventional vein harvesting in coronary artery bypass grafting, the NT technique showed increase in the patency rate but had a higher risk of post operative leg paraesthesia. | ||||
