Clinical use of the 3m 2.5 mm mechanical microcoupling device in free tissue transfer

The long‐term patency of the 2.5 mm mechanical microvascular anastomotic device (the Unilink system) was evaluated in 10 cases of free flap transfer in nine patients between July 1991 and July 1993. Flap survival indicated adequate patency to time of healing. All cases were considered critical end‐to‐end venous anastomoses, without a parallel conventional microvascular hand‐sewn anastomosis associated with the coupling device. The types of flaps used were seven rectus abdominous and one each of serratus anterior and lateral arm muscles and a free jejunum.
