Effect of modified distally based propeller sural perforator flap for defect at foot and ankle and lateral gastrocnemius artery perforator flap for defect at donor site / 中华整形外科杂志

ABSTRACT

Objective@#To investigate the effect of modified distally based propeller sural perforator flap for defect at foot and ankle and lateral gastrocnemius artery perforator flap for defect at donor site.@*Methods@#From January 2014 to January 2016, 12 cases with defects at foot and ankle were reconstructed by modified distally based propeller sural perforator flaps. The result ed defects at donor sites were reconstructed by lateral gastrocnemius artery perforator flaps.The flaps size ranged from 5.5 cm×3.5 cm to 13.0 cm×7.0 cm for modified distally based propeller sural perforator flaps, and 7.0 cm×4.0 cm to 10.0 cm×6.0 cm for lateral gastrocnemius artery perforator flaps. The 12 cases included 10 males and 2 females, aged from 14 to 48 years (25.7 years on average).@*Results@#The lateral gastrocnemius artery perforators existed consistently in all cases. All flaps survived completely with no vascular crisis, wound dishesecense or obvious swelling. Primary healing was achieved in both recipient and donor sites. 12 cases were followed up for 6-14 months (12.4 months on average) with satisfactory esthetic and functional result in both recipient and donor sites, only linear scar was left on the donor sites.@*Conclusions@#The lateral gastrocnemius artery perforator flap is suitable for defect left by modified distally based propeller sural perforator flap. Combination of the two flaps is an optional choice for defects at foot and ankle.
