Insights
This study introduces an oversized preexpanded flap using intercostal artery perforators for repairing large pediatric upper limb skin defects, offering a viable reconstructive solution with minimal donor site issues.
Area of Science:
- Plastic Surgery
- Pediatric Reconstructive Surgery
- Tissue Expansion Techniques
Background:
- Pediatric upper limb skin lesion repair presents challenges due to flap size limitations and donor site morbidity.
- This study aimed to develop an oversize preexpanded flap utilizing intercostal artery perforators for extensive pediatric upper extremity resurfacing.
Observation:
- Eleven pediatric patients with extensive upper limb skin lesions were treated using preexpanded intercostal artery perforator flaps.
- Tissue expansion averaged 133 days, achieving a mean final volume of 1713 mL.
- Flaps were based on 2-6 pedicles, resurfacing a mean defect area of 238 cm².
Findings:
- The preexpanded intercostal artery perforator flap facilitated single-stage repair of large skin defects on the upper limb.
- Primary donor-site closure was successful in all cases.
- Marginal necrosis occurred in 5 cases, with satisfactory aesthetic and functional outcomes reported for reconstructed limbs.
Implications:
- This pedicled flap technique offers a valuable method for extensive upper limb skin lesion repair in children.
- The approach minimizes donor-site morbidity, making it particularly suitable for pediatric reconstructive surgery.
- Oversize preexpanded flaps provide a promising solution for complex pediatric limb reconstruction.
Background:
The repair of extensive upper limb skin lesions in pediatric patients is extremely challenging due to substantial limitations of flap size and donor-site morbidity. We aimed to create an oversize preexpanded flap based on intercostal artery perforators for large-scale resurfacing of the upper extremity in children.
Method:
Between March 2013 and August 2016, 11 patients underwent reconstructive treatment for extensive skin lesions in the upper extremity using a preexpanded intercostal artery perforator flap. Preoperatively, 2 to 4 candidate perforators were selected as potential pedicle vessels based on duplex ultrasound examination. After tissue expander implantation in the thoracodorsal area, regular saline injections were performed until the expanded flap was sufficient in size. Then, a pedicled flap was formed to resurface the skin lesion of the upper limb. The pedicles were transected 3 weeks after flap transfer. Flap survival, complications, and long-term outcome were evaluated.
Result:
The average time of tissue expansion was 133 days with a mean final volume of 1713 mL. The thoracoabdominal flaps were based on 2 to 6 pedicles and used to resurface a mean skin defect area of 238 cm ranging from 180 to 357 cm. In all cases, primary donor-site closure was achieved. Marginal necrosis was seen in 5 cases. The reconstructed limbs showed satisfactory outcome in both aesthetic and functional aspects.
Conclusion:
The preexpanded intercostal artery perforator flap enables 1-block repair of extensive upper limb skin lesions. Due to limited donor-site morbidity and a pedicled technique, this resurfacing approach represents a useful tool especially in pediatric patients.
