Double perforator flaps offer a viable alternative for reconstructing large posterior trunk defects, minimizing donor site morbidity. These flaps are well-tolerated, even with adjuvant radiotherapy, providing a successful reconstructive option.

Area of Science:

  • Plastic Surgery
  • Surgical Oncology
  • Reconstructive Surgery

Background:

  • Large posterior trunk defects often result from radical sarcoma excisions.
  • Conventional reconstruction methods like free flaps or local flaps have limitations, especially with adjuvant radiotherapy.
  • Perforator flaps, particularly double perforator flaps, are emerging as effective solutions for extensive defects.

Purpose of the Study:

  • To evaluate the efficacy and safety of double perforator flaps for reconstructing large posterior trunk defects.
  • To assess complications and tolerance to postoperative radiation therapy.
  • To compare double perforator flaps with conventional free flap reconstructions.

Main Methods:

  • A retrospective analysis of consecutive double perforator flaps used for posterior trunk defects.

  • Detailed recording of defect size, flap design, perforator origin, and complications.
  • Assessment of flap survival, venous/arterial issues, need for secondary procedures, and radiation tolerance.

    • Main Results:

    • Twenty-four double perforator flaps were performed in 12 patients with an average defect size of 168.5 cm².
    • One flap was lost due to arterial issues; two experienced venous insufficiency requiring intervention.
    • Postoperative radiation therapy was generally well-tolerated, with minimal donor site morbidity due to primary closure.

    Conclusions:

    • Double perforator flaps represent a viable and effective alternative to free flaps for large posterior trunk defects.
    • This technique effectively utilizes the native vascular supply and abundant local tissue.
    • Primary donor site closure minimizes complications and morbidity, making it a favorable reconstructive option.
