[Reconstruction of donor site defect after harvesting anterolateral thigh flap by V-Y flap pedicled with the lateral superior genicular perforator].

OBJECTIVE
To investigate the clinical application of V-Y flap pedicled with the lateral superior genicular perforator for donor site defect after harvesting anterolateral thigh flap.


METHODS
From June 2011 to June 2012, 9 cases with defects at hands and feet were treated with anterolateral thigh flaps. The defects left at the donor sites were consequently reconstructed with V-Y flap pedicled with the lateral superior genicular perforator. The defects left by V-Y flap were closed directly.


RESULTS
All the 9 anterolateral thigh flap survived completely. 5 flaps underwent thinning surgery 6-8 months after operation. The flaps had a good appearance, texture, color and elasticity. The 8 perforator flaps survived completely with partial necrosis in 1 flap at the proximal end. The average healing time was 17 days. There was no obvious depression at donor sites with normal function.


CONCLUSIONS
The method is easily performed with optional therapeutic effect. It is a modified improvement for the anterolateral thigh flap.
