Objective To explore the effect of improved V-Y advancement flap with major artery perforator on repairing several skin and soft tissue defects in whole body.
Methods From March 2015 to June 2017, 4 cases with pressure ulcer in sacrococcygeal region, 4 cases with pressure ulcer at ischial tuberosity, 2 cases with scalp and skull defects at occiput, 1 case with secondary wound after tumor resection in axillary region, and 2 cases with skin and soft tissue defects caused by other trauma were hospitalized, with disease duration ranging from 1 week to 6 months. Bones, blood vessels, or nerves were exposed in wounds of 11 cases. After debridement, wounds with area ranging from 5 cm×4 cm to 15 cm×12 cm were repaired by improved V-Y advancement flap with major artery perforator including occipital artery perforator, arteria glutaea perforator, intercostal artery perforator, and peroneal artery perforator, and the area of flap ranged from 11 cm×5 cm to 35 cm×20 cm. Distal end of flaps additionally carried 1 major artery perforator in 4 cases.
Results All flaps survived well without hemodynamic disorder, and wounds and donor sites healed well. During the follow-up for 3 to 18 months, the flaps were good in appearance with similar color and texture to normal skin around wound and without recurrence of rupture.
Conclusions Compared with traditional V-Y advancement flap, the improved V-Y advancement flap with major artery perforator has the advantages of larger repair area, longer advance distance without tension, simple operation, and good appearance after operation, which is beneficial to clinical application.
