Abstract

Background and Aim Endoscopic radial artery (RA) harvest (ERAH) is an alternative to open RA harvest (ORAH) technique. Our aim was to compare clinical outcome, patent satisfaction and 1-year angiographic patency rates after ERAH and ORAH. Patients and methods 50 patients undergoing multivessel CABG were prospectively randomized to two groups. In the ERAH group (25 patients) the RA was harvested endoscopically and in the ORAH group (25 patients) openly. Results There were not differences between the groups in preoperative characteristics. Length of skin incision was shorter in ERAH (p<0.001) but there were not differences in the length of RA, harvest time, blood flow and pulsatility index after ERAH and ORAH. Wound healing was uniformly smooth in ERAH and there were 2 haematomas and 1 infection in ORAH. Postoperatively, major neuralgias were present in 5 patients in ORAH and none in ERAH (p=0.05) and minor neuralgias in 11 and 3 patients (p=0.02) respectively. Twenty-four patients in ERAH and 4 in ORAH graded their experience as excellent (p<00001). One-year angiographic RA patency was 90% without intergroup difference. Target vessel stenosis < 90% adversely affected RA patency (p<0.0001). Conclusions In expert center, ERAH has no negative impact on time harvest, length and quality of RA conduit. Moreover, ERAH may provide better wound healing, and is associated with less neuralgias, excellent cosmetic result and better patient satisfaction. RA graft patency is unaffected by the harvesting technique and is excellent when placed to a target coronary artery vessel with stenosis > 90%.
