Venous monitoring and evaluation present a dilemma in free flap care. Duplex ultrasonography provides information on vessel flow and anatomy. This case demonstrates the use of duplex technology in identifying problems following vascular microsurgery, and it raises discussion of possible future roles for the application of duplex ultrasonography in the management of free flaps.
