Author planed peroneal artery perforator flap for ankle reconstruction and experienced successful result using sural neuro-lesser saphenous venous flap due to an unexpected event. A male Asian patient, 24 years old, had a history of recurrent operation wound disruption in the ankle region. Under general anesthesia, peroneal perforator and saphenous vein, as well as the sural nerve branches, were identified and preserved. In the process of flap rotation, an accidental division of peroneal artery perforator has occurred. Despite the division of the perforator, circulation was normal. The patient experienced no complication after the surgery. Some study reported that accompanying arteries and the vascular plexus around the sural nerve communicate. In conclusion, sufficient blood supply was possible only with the accompanying artery of the sural nerve without peroneal perforator. So, it is essential to always preserve not only perforator but also neurovascular bundles at any circumstances and any location.
