Pedicled anterolateral thigh flap: A versatile flap for complex regional defect reconstruction

Area of Science:

• Plastic Surgery
• Reconstructive Surgery
• Microsurgery

Background:

• Soft-tissue defects in the lower abdomen, perineum, groin, and trochanteric areas present significant reconstructive challenges.
• Limited donor sites for pedicled flaps in these regions necessitate innovative solutions.
• The anterolateral thigh (ALT) flap is advantageous due to its versatile tissue composition and long, reliable pedicle.

Purpose of the Study:

• To evaluate the efficacy and reliability of the pedicled anterolateral thigh (ALT) flap for reconstructing complex soft-tissue defects.
• To assess outcomes and complications associated with pedicled ALT flap reconstruction in challenging anatomical locations.

Main Methods:

• A case series involving ten patients undergoing reconstruction of lower abdomen, groin, trochanteric, scrotal, and penoscrotal defects using a pedicled ALT flap.
• Flap customization based on individual defect requirements.
• Evaluation of flap success, complications, and donor site healing.

Main Results:

• No flap loss was observed in the case series.
• Minor complications were infrequent, and all patients were satisfied with the aesthetic results.
• Satisfactory graft take was achieved in donor sites requiring split skin grafting.

Conclusions:

• The pedicled ALT flap is a dependable and effective option for complex soft-tissue reconstruction in the lower abdomen and perineal regions.
• This flap provides stable coverage and protects underlying structures with a low complication rate.
