RÉSUMÉ
On October 23, 2017, a 52-year-old male patient with 3 recurrences of dermatofibrosarcoma protuberans in the left shoulder and chest was admitted to the Department of Burns and Plastic Surgery of Dali Bai Autonomous Prefecture People′s Hospital. Dermatofibrosarcoma protuberans on the skin were completely resected, leaving wound defect of 10 cm×10 cm. The wound was planned to be repaired by the transplantation of right anterolateral thigh perforator free flap. However, the anterolateral thigh perforator branch was absent during flap removal, and only one small perforating branch was found. Moreover, it was difficult to separate. Therefore, this flap cutting was given up. The anteromedial thigh perforator was explored through the same incision, and a thicker perforator was found, which was supplied by an independent iatrogenic artery. The length and diameter of the vascular pedicle matched with the blood vessels in the receiving site. An anteromedial thigh perforator flap (10 cm×10 cm) was cut to repair the defect. The postoperative 9-month follow-up revealed that the color, texture, and thickness of the flap were good, the two-point discrimination distance was 30 mm, and the linear scar remained at the donor site of right thigh.
RÉSUMÉ
From November 2015 to July 2017, six patients with skin and soft tissue defects of vulva, vagina, and buttock after resection of vulvar tumors were hospitalized in our unit. All patients were female, aged 45-70 years. Among them, four patients had bilateral defects, and two patients had unilateral defect. The defect area on each side ranged from 6 cm×4 cm to 12 cm×6 cm. Internal pudendal artery perforator " angel wing" island flaps were used to repair and reconstruct the defects. The area of flaps ranged from 7 cm×5 cm to 14 cm×7 cm. The donor sites were sutured directly. All 10 flaps of 6 patients survived. Two patients had local incision infection 3 days after operation. One of the two patients was healed 2 weeks after dressing change, and the other one underwent debridement and suture 1 week after dressing change and was healed 1 week after surgery. Follow-up for 6-12 months after surgery showed no recurrence of tumors, no eversion of vagina, better shape of vulva in bilateral reconstruction cases, and slightly worse symmetry in unilateral reconstruction cases. The skin of the reconstructed area was soft, with sensations of pain, temperature, and touch recovered in varying degrees. The distance of a two-point discrimination was 20-30 mm. Linear scars were left in the flap donor sites, with no impact on squatting or striding. In vaginal examination, 1.5 to 2.0 fingers could be inserted in bilateral reconstruction cases, while 2.0 to 3.0 fingers could be inserted in unilateral reconstruction cases. The anus functioned well during defecation.
