Animal Experiments With Doppler Flow Transducers
In the microsurgery of vessels there exists the need for flow or pressure measurement or both in order to confirm proper reconstruction. Electromagnetic flow probes and Doppler transducers have been used in larger vessels. In arteries of small diameter up to now only reports on electromagnetic measurements have been given in the literature as well as some small remarks about Doppler flow transducers. We obtained some of the first commercially available Doppler flow transducers from 1 to 40 mm diameter with the Delalande apparatus. We investigated these transducers in the laboratory and tested them in vitro and in vivo.
