Sural Vessels as Recipient Vessels for Free Flap Transfer to the Single Vessel Leg.

Abstract

Free flaps have been widely used in lower leg reconstruction. However, in cases with extensive injury to the vessels as well as to the bone and soft tissues, and having only one intact major vessel in the lower leg(single vessel leg), careful selection of recipient vessels for the free flap transfer is mandatory for preventing further vascular compromise of the distal lower leg. The sural artery and its vena comitantes are frequently protected form externally harmful forces by the bulky surrounding gastrocnemius muscle and can be used as recipient vessles for free flaps without any detrimental influence on the vascularity of the distal lower leg. In our department, three latissimus dorsi muscle free flap were transferred with sural vessels as recipient vessels in the reconstruction of the single vessel legs. Except for one case of flap failure due to serious infection at the microvascular anastomoses site, all the other cases were successfully reconstructed without any necrosis of the gastrocnemius muscle or the distal leg. In addition, the sural vessels were easily accessed in any patient position and their caliber was similar to that of the vascular pedicles of the donor muscle flaps. In conclusion, the sural vessels can be another useful option in selecting recipient vessels for free flap transfer in the reconstruction of the single vessel leg.
