The posterior interosseous artery free flap.

Summary

Retrograde flow in the posterior interosseous artery failed to perfuse its associated flap. The flap was successfully salvaged using a free tissue transfer technique based on proximal vessels.

Area of Science:

  • Plastic Surgery
  • Vascular Surgery
  • Microsurgery

Background:

  • The posterior interosseous artery flap is a common reconstructive option.
  • Adequate perfusion is crucial for flap viability.

Observation:

  • Retrograde flow within the posterior interosseous artery was insufficient to perfuse the flap.
  • The flap's viability was compromised due to inadequate blood supply.

Findings:

  • The posterior interosseous artery flap failed despite retrograde arterial flow.
  • Successful flap transfer was achieved by utilizing proximal posterior interosseous vessels for a free tissue transfer.

Implications:

  • This case highlights potential perfusion failures in posterior interosseous artery flaps.
  • Free tissue transfer provides an alternative salvage strategy when primary flap perfusion is compromised.
  • Understanding vascular anatomy variations is critical for successful reconstructive surgery.
