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 multi-digit 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 multi-digit defects were included in this study. The details of the clinical features were collected, and the following were successively analyzed: the preoperative Computed Tomographic Angiography (CTA) and Color Doppler Sonography (CDS) examinations for flap design, the intraoperative anatomy for perforator vessel, defect reconstruction and interphalangeal range of motion (ROM) and tactile sense, pain sense and two-point discrimination recovery results.Results: CTA and CDS performed preoperatively could accurately and rapidly identify the position, location and course of the SCIP flap. All wounds healed by the first follow-up and no complications occurred at the follow-up visit. All flaps survived, the patients achieved proximal interphalangeal joint (PIP) ranges of motions (ROM) from 80 to 100 degree and distal interphalangeal joint (DIP) ROM from 65 to 80 degree. The tactile sense and pain sense recovered, and average of the two-point discrimination scores was 9.3mm (range 7-12mm). 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 multi-digit defect reconstruction in pediatric patients in the clinic.
