ABSTRACT
Objective@#To investigate the anterior branch of subcostal artery perforator flap for defects at the lower abdomen or distal sites.@*Methods@#Ten patients were treated, including 6 males and 4 females, aged 25 to 62 years, mean (38.2 ± 6.5) years old. The anterior branch of subcostal artery perforator flap was designed in 10 cases, of which 1 case was free flap carrying the accompanying nerve. 9 cases had defects at abdomen and 1 case at the foot. The flaps size was 4 cm×8 cm-7 cm ×15 cm.@*Results@#All the 10 flaps survived completely with no vascular crisis. The abdominal shape was good with only linear scar. The free flap was used for plantar wound with nerve anastomosis of accompanying nerve with the medial plantar nerve. During the follow-up period of 6 months, the flap sensory recovery area reached more than 60% with two-point discrimination as 20-25 mm.@*Conclusions@#The anterior branch of subcostal artery perforator flap has a stable vascular pedicle with reliable vascular network and sensory nerve.
