The arterialised saphenous venous flow‐through flap for managing the radial forearm free flap donor site

BACKGROUND: The radial forearm fasciocutaneous flap (RFFF) is a workhorse flap, however concerns with donor site morbidity include tendon exposure, delayed wound healing, impaired sensitivity, and poor cosmesis, have seen it fall out of favor. We present a method of using an arterialised saphenous flow through flap to reconstruct the RFFF donor site. METHOD: A cohort study of six patients (five male, one female; mean age 59 [range 19–90]) who had their RFFF donor site reconstructed with an arterialised saphenous flow through flap is presented. The use of multiple peripheral efferent venous anastomoses, flap rotation 180 degrees prior to inset, and the ligation of intra‐flap connecting veins were three modifications employed. Primary outcomes include complication rates. Secondary outcomes were patient reported outcome measures via the Michigan Hand Outcomes Questionnaire, and patency and flow through the flap. RESULTS: In all six cases, there was flap survival. RFFF dimensions ranging from lengths of 6–15 cm (mean 11.5 cm) and widths of 4–6 cm (mean 5.3 cm), with an average flap area of 58 cm(2) (range 24–90). There were no total flap losses, one partial superficial flap loss and one minor donor site delayed healing, over a mean follow‐up of 6 months (4–24 months). The average overall patient satisfaction was 91 on Michigan Hand Outcomes Questionnaire. Pain was well tolerated with a low average pain score of 15. CONCLUSION: The modified arterialised saphenous flow through flap is a useful option for reconstructing the soft tissue defect and reconstituting the radial artery after RFFF harvest.
