Hand blood supply in radial forearm flap donor extremities: a qualitative analysis using doppler examination.

This retrospective study evaluated the contribution of the forearm arteries to the blood supply of the hand after radial forearm flap surgery. Doppler ultrasound examinations of the radial, ulnar, anterior interosseous and posterior interosseous arteries were performed in the distal forearm using a continuous emission directional Doppler and a modified Allen test. Twenty-seven patients were included in this investigation which demonstrated a significant contribution of the anterior interosseous artery to hand vascularity after radial forearm flap surgery.
