A Safe and Innovative Method to Apply Venous Coupler in Oncologic Head and Neck Reconstruction

open access: yesIndian Journal of Plastic Surgery, 2023
Venous anastomosis with a coupler device is an effective alternative to the hand-sewn anastomosis technique. Twist in the veins following a coupler anastomosis is a troublesome complication that needs a revision of venous anastomosis. The author proposes
