ABSTRACT

Objective To investigate the application of peroneal artery chain perforator flap in repairing skin and soft tissue defects of ankle and lower leg and the corresponding clinical effect.Methods From 2005 to 2010,19 cases of skin and soft tissue'defects of the ankle and lower leg were treated by using peroneal artery chain perforator flaps.The sites of peroneal artery branches were detected by using Doppler flowmeter before operation.Supplied by the chain form of terminal branches of the peroneal artery,the cutaneous fulcrum straightly nearest to the wound was selected as the rotation point to design the flap,with area ranging from 25 cm × 8 cm to 16 cm × 6 cm.Results The follow-up for 1.5- 42 months revealed that all cases of flap survived with satisfactory shape,except for one case suffered from distal skin flap necrosis.Conclusions The peroneal artery chain perforator flap with unsteady peduncle has no restrictions of peduncle sites and can be cut flexibly.It is a perfect method in repair of soft tissue defect of ankle and lower leg.
