Free superficial circumflex iliac artery perforator flap with a single-pedicle bilobed design for pediatric multifinger defect reconstruction

Abstract Objectives This paper describes imaging and anatomical features, in order to assess the feasibility of superficial circumflex iliac artery perforator (SCIP) flap with a single-pedicle bilobed design for multifinger skin and soft tissue reconstruction in pediatric patients. Methods A total of 7 pediatric patients who were being treated with free single-pedicle bilobed SCIP flap reconstruction for multifinger defects were included in this study. The details of the clinical features were collected, and the following were successively analyzed: the preoperative CTA and CDS examinations for flap design, the intraoperative anatomy for perforator vessel, defect reconstruction and the postoperative aesthetic, motor function and sensation recovery results. Results CTA and CDS performed preoperatively could accurately and rapidly identify the position, location and course of the SCIP flap. All flaps survived well, all wounds healed by the first follow-up and no complications occurred at the follow-up visit. The fingers had good aesthetic appearance, there was recovery of motor function and protective sensation, and the donor area was primarily sutured with good scar concealment in the underwear region. Conclusion CTA and CDS performed preoperatively are accurate and intuitive methods for assessing the location and course of SCIP. The SCIP flap is highly suitable for pediatric patients due to its small caliber, specific functional and aesthetic benefits. It can be designed in a lobulated fashion in order to repair two or more wounds during one surgery. We suggest that the free single-pedicle bilobed SCIP flap should be considered an optimal choice for multifinger defect reconstruction in pediatric patients in the clinic.
