AbstractMedicinal leech therapy is a common adjuvant modality used to treat venous congestion following threatened microvascular anastomosis. Migration and tunneling of a leech beneath a surgical reconstruction is a rare event that is seldom mentioned in the literature and worthy of further discussion. We present a rectus abdominus myocutaneous free tissue transfer that was used to cover a large alloplastic cranioplasty following resection of a previously radiated skull base malignant meningioma. The flap became congested postoperatively and required leech therapy after surgical salvage. Three days after flap salvage, the subject was once again brought back to the operating room for surgical exploration when a leech was witnessed to migrate beneath the threatened free flap. Duplex ultrasound was used intra-operatively to localize the leech 12 cm from its bite and assist with its successful removal. Tunneling of the leech beneath the flap is a rare complication, and localization underneath a myofascial or myocutaneous flap may be difficult. Duplex ultrasound is a simple and reliable method to localize the leech and allow for its removal through a minimal access incision.Copyright © 2013 Wiley Periodicals, Inc.
