The Allen's test: revisiting the importance of bidirectional testing to determine candidacy and design of radial forearm free flap harvest in the era of trans radial endovascular access procedures

摘要

Background: The radial forearm free flap is a workhorse free flap. The radial artery, which supplies it, is increasingly being used for endovascular access. A complication of this is radial artery occlusion. Although often asymptomatic it can compromise future free tissue transfer.
