Vram flap transposition in pelviperineal reconstruction. A technical note.

Area of Science:

• Surgical Oncology
• Reconstructive Surgery
• Pelvic Surgery

Background:

• The vertical rectus abdominis myocutaneous (VRAM) flap is a reliable method for perineal reconstruction following pelvic exenteration.
• Flap compromise, though infrequent, often stems from improper inset or postoperative management.
• This article focuses on optimizing VRAM flap transposition within the pelvis to ensure viability.

Discussion:

• VRAM flap rotation strategy is dictated by the perineal defect's location (anterior vs. posterior) and patient positioning (supine vs. prone).
• An algorithmic approach is presented to guide precise flap inset, safeguarding the vascular pedicle.
• Specific rotation techniques (270° sagittal for anterior defects, 180° coronal for posterior defects) are detailed to prevent pedicle compromise.

Key Insights:

• Tailoring flap rotation to the specific defect and patient position is critical for successful VRAM flap reconstruction.
• A step-by-step method ensures the cranial portion of the flap adequately covers the defect without tension.
• Adherence to these technical details minimizes the risk of torsion or tension on the epigastric vessels.

Outlook:

• Implementing these refined VRAM flap transposition techniques can enhance reconstructive outcomes in pelvic surgery.
• Further studies could explore long-term functional and aesthetic results with these optimized methods.
• Standardizing these technical guidelines may improve consistency and reduce VRAM flap-related complications.
