Alteration of a radial forearm flap to adjust to the superficial radial artery: a case report

  • 1Department of Plastic and Reconstructive Surgery, Severance Hospital, Yonsei University College of Medicine, Seoul, Korea


Aberrant branches of the radial artery at the level of the forearm have rarely been reported. Preoperative workups to identify aberrant branches of this type have also seldom been performed. However, surgeons elevating a radial artery-based flap should consider the possibility of aberrant arterial branching. Otherwise, the circulation of both the flap and hand may be endangered. We present a case of an anomalous radial artery branch that resulted in an intraoperative alteration of the flap design. A novel technique was used to preserve the circulation of the entire flap, and the patient recovered with adequate healing of the flap and donor areas. No hand function deficits or subjective complaints were noted. In conclusion, surgeons should be aware of the superficial radial artery or other aberrant branches of the radial artery that may be located in various locations during radial artery-related flap elevation.
