Patterns of vascular anastomoses vs. success of free groin flap transfers.

A series of 40 free groin flap transfers is reviewed and analyzed with regard to the factors influencing success or failure. Emphasis is placed on the patterns of venous anastomosis used, and the use of autogenous vein grafts in the arterial limb. The series was too small to establish that any one of the 4 types of venous hookups was superior to the others. However, we would suggest that the superficial venous conduit in the flap, if there is one, be connected to a vein in the recipient area and not to the deep venous system of the flap.
