Abstract
© The Author(s) 2020. Background: Recent studies have revealed that radial artery grafts have excellent patency rates. However, harvesting of the radial artery is generally limited to the non-dominant forearm. We would like to demonstrate the effectiveness and safety of bilateral radial artery harvesting. Methods: We enrolled 173 patients undergoing coronary artery bypass. Bilateral RA were used in 64 cases and unilateral in 109. The primary endpoint was post-harvest forearm and hand complications. Results: Forearm and hand complications occurred immediately postoperatively in 28.1% of the bilateral radial artery group, significantly more than in the unilateral radial artery group (8.3%). During follow-up, no overall difference was found in post-harvest forearm and hand complications. However, the forearm and hand perception score in the bilateral radial artery group was higher: 8.78 ± 1.45 vs. 8.35 ± 0.84 in the unilateral radial artery group. Subgroup analysis in the bilateral radial artery group revealed no significant difference in forearm and hand perception score between the dominant and non-dominant donor forearms (8.78 ± 1.45 in non-dominant and 8.66 ± 1.00 in dominant forearms). The bilateral radial artery group had more arterial coronary anastomoses, longer operative times, and longer cardiopulmonary bypass times. However, a backward multiple linear regression model revealed that only two factors related to operative time, these were the number of arterial distal coronary anastomosis and cardiopulmonary bypass time. Conclusions: This study demonstrated that bilateral radial artery conduits can be used effectively and safely with no difference in persistent complications related to the hands and forearms.
