title: The use of the ultrasound Doppler flowmeter in reconstructive microvascular surgery.
abstract: A method is described for predicting the outcome of experimental free flaps at the time of surgery using a directional ultrasound Doppler flowmeter. Tests of both arterial and venous anastomoses have been developed. Provided that both anastomoses are individually assessed, the technique is 100% accurate and is recordable. Spectral analysis of truly directional Doppler signals has provided knowledge of the peripheral resistance within a flap.
