title: Noninvasive evaluation of the lower extremity arterial tree and graft surveillance.
abstract: The application of duplex ultrasonography in the evaluation of lower extremity arterial occlusive disease and in graft surveillance has enhanced significantly the vascular surgeon's diagnostic armamentarium. With continued refinements in gray scale image resolution, color flow, and spectral analysis, color duplex ultrasonography eventually will replace angiographic evaluation in carefully selected patients as the primary pre-interventional testing modality.
