Endoscopic radial artery harvesting: results of first 300 patients.

Background: With the expanded use of the radial artery as a bypass conduit in patients undergoing coronary artery bypass grafting, an endoscopic radial artery harvesting method was used to improve esthetics and patient acceptance, and possibly, to decrease hand neurologic complications.

Methods: After informed consent and confirmation of adequate ulnar collateral blood flow, 300 consecutive patients undergoing coronary artery bypass grafting had their nondominant radial artery endoscopically removed through a small 3-cm incision just proximal to the radial styloid prominence. Standard endoscopic vein equipment (30-degree 5-mm endoscope, subcutaneous retractor, and vessel dissector) with ultrasonic harmonic coagulating shears were used.
