Radial nerve morbidity in radial artery free flaps: Harvest of cephalic vein versus venae comitantes.

摘要

Background: The purpose of the present paper was to determine the radial nerve morbidity associated with harvest of different venous conduits in the radial artery free flap. Methods: Retrospective study comparing subjective and objective symptoms of radial nerve morbidity in 51 consecutive free flaps over a 3-year period. Results: Damage to the radial nerve occurred in 9% (1/11) of patients in the cephalic vein group versus 18% (4/28) in the venae comitante group. Conclusions: Raising the cephalic vein for venous drainage in the radial artery free flap doubles the incidence of radial nerve morbidity.
