Microvascular free tissue transfer is an essential technique for treating malignant diseases of the head and neck. The Microvascular Anastomotic System (3M, St Paul, Minn) uses the friction-fit union of implant rings composed of high-density polyethylene and type 316L stainless steel pins. Several experimental and clinical studies of this system have been reported.1- 3 We have treated more than 100 cases of venous anastomoses with head and neck free flap reconstruction without any vascular problems.
