Fourier analysis of peripheral blood pressure and flow in intraoperative assessment of infrainguinal arterial reconstructions.

Abstract

AIM To assess infrainguinal arterial reconstructions by intraoperative flowmetry under the distal anastomosis using a fast Fourier transformation; calculate and compare the amplitude ratios of peripheral arterial blood pressure and volume flow before and after drug-induced vasodilation of occluded bypass grafts and bypass grafts that have been patent at… (More)
