Free omental tissue transfer for extremity coverage and revascularization

Area of Science:

• Plastic Surgery
• Microsurgery
• Wound Reconstruction

Background:

• The omentum is a well-vascularized, pliable tissue ideal for soft-tissue defect reconstruction.
• It possesses a long vascular pedicle (35-40 cm) with large vessels, simplifying microsurgical procedures.
• The omentum can facilitate flow-through revascularization for ischemic distal extremities.

Observation:

• Six cases of free omental tissue transfer for upper and lower extremity reconstruction were reviewed.
• Three cases utilized distal anastomoses to leverage the flap's flow-through capacity for arterial augmentation.
• All transfers successfully achieved wound coverage and extremity revascularization.

Findings:

• Microvascular omental transfer enables simultaneous reconstruction and revascularization of difficult extremity wounds.
• The omentum's properties reduce technical challenges in microsurgery.
• This technique is effective for distal arterial augmentation in ischemic extremities.

Implications:

• Omental tissue transfer is an underutilized yet powerful option for complex extremity wound management.
• It offers a versatile solution for simultaneous soft-tissue coverage and vascular restoration.
• This approach enhances reconstructive outcomes in challenging limb salvage scenarios.
