A Simple Skin Incision Design for Pediatric Superficial Branch of Superficial Circumflex Iliac Artery

BACKGROUND: Superficial circumflex iliac artery (SCIA) perforator flap is one of the demanding flaps. However, little is known about SCIA anatomy, which is crucial for successful SCIA perforator flap elevation, in children. We assessed the efficacy of our incision design to detect the superficial branch of the SCIA in vivo. METHODS: Eleven consecutive pediatric patients who required harvesting (eg, skin grafts or vascularized lymph node transfer) were assessed. All possible congenital vascular malformation cases were excluded. To reduce potential bias, all groin procedures were performed on the contralateral side of malformations. After inguinal area mapping, 1.5-cm skin incision was made. From the window opened by the skin incision, tiny perforation to the skin surface was detected for further dissection. Following the tiny branch, the main trunk of the superficial circumflex vascular bundle was dissected. The whole vascular bundle, artery, and major vein from the bundle were dissected and their sizes were measured. RESULTS: Of the 11 patients, 4 were boys; the age range was 5 months to 14 years (mean age: 3.2 years). Vessel bundle size was 0.7–1.5 (mean: 1.1 mm). In all cases, the bundle was detected within 5 min (1–5, mean: 2.5 min). No vascular damage was observed, and all arteries pulsated well, without requiring additional skin incision. The superficial branch of the SCIA was mainly detected right below the initial skin incision. CONCLUSIONS: Our skin incision design can effectively detect the SCIA in pediatric patients and may be used in adult patients.
