The Effect of Previous Transradial Catheterization on Radial Forearm Free Flaps

Radial forearm free flaps (RFFF) are a versatile option for the reconstruction of a wide variety of soft tissue defects and are particularly common in head and neck surgery. Benefits of RFFF include a relatively short operating time, a long pedicle, and a thinner, more pliable flap. However, in addition to its role in reconstructive surgery, the radial artery may be utilized for a number of other procedures including coronary angiography and percutaneous coronary interventions. Concern has previously been raised that prior catheterization may deleteriously affect the function of the radial artery and in the field of cardiothoracic surgery, individuals are increasingly advising against its use as a graft for coronary artery bypass graft surgery in such circumstances. Despite this, little is known about the effect on RFFF. In this review article, we concisely consider the available evidence of the effect of previous transradial catheterization on the radial artery and discuss the implications for reconstructive surgery. We then summarize the key considerations regarding their use in current practice.
