Abstract:
Objective:To investigate the therapeutic effect of propeller flap with low peroneal artery perforator for defects at ankle and heel.
Methods:From January 2009 to March 2016, 28 cases with skin defects at ankle and heel were treated with propeller flap pedicled by low peroneal artery perforator, including 15 cases of car accidents, 8 cases of pressure injury, 3 cases of wring injury and 2 cases of electricity shock injury. Defects size ranged from 3 cm×3 cm to 4 cm×6 cm. The fibular was divided into 9 segments from head to external ankle. Doppler ultrasound was used to locate the low peroneal artery perforator from the lower 6-9 segments. The flap pivot point was at perforator point at skin surface, with the peroneal artery as flap axis. The length of big blade was the distance from rotate point to distal end of defects. The flap width was half of the length. The ratio of big blade length to width should not exceed 2∶1. The flaps size was from 3 cm×5 cm to 4 cm×10 cm, based on the defect size. The defects at donor site could be closed with small blade directly.
Results:Partial necrosis happened in 1 case due to veneous crisis, which healed after dressing. All the other 27 flaps survived completely. During the follow-up period, the flaps had good match in color and thickness. No secondary operation was needed.
Conclusions:The optimization of propeller flap with low peroneal artery perforator is an idealmethod for defects at ankle and heel, which can avoid the necrosis at distal end of flap.
