Aim: We sought to evaluate our experience with endoscopic radial artery harvesting for coronary artery bypass grafting (CABG).
Methods: From October 2005 to June 2010, 50 patients who underwent endoscopic radial artery harvesting for an elective CABG were prospectively assessed for harvesting characteristics, complications, postoperative and mid-term outcomes.
Results: There were 34 (68%) males and 16 (32%) females, average age 60.8±9.2 years. All but two RA grafts (96%) were successfully harvested endoscopically. Mean harvesting time was 46.2±9.3 min and mean length of harvested grafts was 23.4±2.2 cm. In the post-operative period there were no wound-healing complications; residual forearm edema was recorded in 6 patients (12%) and peripheral neuropathy in 4 patients (8%). At 3 months after the surgery, peripheral neuropathy and residual edema persisted in 2 patients (4%). A significant drop of overall harvesting time (56.2± 18.6 vs. 38.6±8.6 min, P<0.05) and forearm ischemia time (41.8±12.7 vs. 24.2±3.2 min, P<0.01) was found between first and last ten cases in the group.
Conclusion: Endoscopic radial artery harvesting was associated with low risk of post-harvesting complications and most of these disappeared within a 3 months follow-up. However, there was a significant learning curve.
