PURPOSE: The aim is to describe a technique with orthograde dissection of the anterior tibial artery (ATA) used as the recipient vessel for the end-to-end (ETE) anastomosis in defect reconstruction around the knee and for proximal/middle third leg defects with free anterolateral thigh (ALT) and gracilis flaps.
PATIENTS AND METHODS: Between March 2009 and May 2014, 22 patients undergoing lower extremity reconstruction were evaluated. Of those, 4 patients were included. The locations of injury were 3 defects around the knee and 1 defect at the proximal and middle third of the lower leg (mean defect size 18 x 8.5 cm and a range of 17-20 x 5-10 cm). There were 2 cases after trauma and 2 cases with infection. Two free gracilis and 2 free ALT flaps were performed of equal size to the defects. The mean flap pedicle length was 11 cm (range of 7-16 cm) and the mean length of the mobilized recipient vessels was 10.5 cm (range of 6-14 cm).
RESULTS: One flap loss (ALT) occurred, requiring a salvage procedure with a latissimus dorsi flap, whereas wound dehiscence at the donor site and a hematoma below the ALT flap was observed in 2 cases, requiring small revision. After a mean follow-up of 52 months (range of 38-87 months), there was stable soft tissue coverage in all patients.
CONCLUSION: By orthograde dissection of the ATA, an adequate vessel length and size may be achieved, improving arc of rotation to successfully cover more distant defects.
