Abstract

Dual venous anastomosis in radial forearm free flap surgery increases chances of flap survival as compared to anastomosing only the superficial system. A 48-year-old male patient who had received three previous microsurgical reconstructions and radiotherapy presented with recurrent oral cavity carcinoma. Two of these reconstructions were anastomosed to the left side neck vessels. The recurrence was in the left half of the soft palate. The left neck and underlying vessels were severely scarred and fibrotic, and only 2 cm of the left internal jugular vein (IJV) could be circumferentially mobilized for anastomosis, allowing for only one venous anastomosis. The radial forearm free flap was harvested and a tributary of the cephalic vein was preserved in the proximal part to act as a conduit for drainage of one of the venae comitantes. The cephalic vein was anastomosed end-to-side to the IJV and one venae comitantes to the preserved tributary in end-to-end fashion. The flap survived and the patient was discharged in a week. This novel method helps to drain both venous systems through one available neck vein.
