An anomaly of the radial artery--relevance for the forearm flap.

The radial artery runs between the Flexor Carpi Radialis tendon and the Brachioradialis tendon in the distal one-third of the forearm. Here it is covered only by the superficial fascia, subcutaneous tissue and skin, so that it is easy to palpate. However, the case reported here describes a rare anomaly of the radial artery which has relevance to use of the forearm flap.
