| pubmed-article:6219729 | pubmed:abstractText | 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. | lld:pubmed |
