Microsurgical anastomosis using anterior versus posterior tibial artery in lower limb free tissue transfer.

Incidence of lower limb free flap failure is low (<5%) and not influenced by use of ATA versus PTA for microsurgical anastomosis. The choice of target vessels for microsurgical reconstruction of the lower limb should be predicated upon factors other than aversion to one or another vessel. If all other microsurgical considerations are equal, the surgeon can exercise personal preference.
