ABSTRACT
-The Microvascular Anastomotic System (3M coupler) uses a friction-fit union of implant
rings composed of high-density polyethylene and stainless-steel pins. Several reports
have described equal or greater patency rates, as well as more rapid performance,
using the device, compared to conventional suturing techniques. Eighty-nine patients,
who underwent head and neck surgery with free-tissue transfers, using the Microvascular
Anastomotic System, were evaluated. A hundred and twenty-one venous anastomoses were
done using the device. All but one was done in an end-to-end manner. Arteries were
anastomosed with a conventional suture technique. The flap survival rate was 100 percent.
The authors conclude that the device is reliable and time-sparing for end-to-end venous
anastomoses in head and neck reconstruction.
