About Video

The radial artery forearm flap is harvested from the flexor aspect of the forearm. Its skin paddle is supplied by multiple perforators from the radial artery. Flap dissection is initiated in the subfascial plane from the ulnar side up to the septum near the flexor carpi radialis tendon. Subsequent dissection is carried out from the radial side in the subfascial plane up to the border of brachioradialis tendon. Care is taken to preserve the superficial veins with the flap and avoid damage to the superficial radial nerve passing from the undersurface of the brachioradialis tendon. The septum is then separated from the radius bone with sharp dissection. The radial artery is then divided at the distal edge of the flap. After dividing the distal pedicle at the wrist, the dissection is then continued in the distal to proximal direction. The vascular pedicle can be dissected proximally up to the desired length. The venae commitantes with the radial artery are sufficient for venous drainage. However, the superficial veins also can be reliably used for venous drainage. A suprafascial dissection will avoid exposure of the tendon and damage to the superficial radial nerve and reduce the donor site morbidity.
