Visualization of Blood Flow in an Undermined Pressure Ulcer Revealed by Sonographic Imaging and Clutter Suppression Post-Processing: A Case Report

Abstract

The authors report a case of a middle-age man presenting with a category IV pressure ulcer (PU) over the sacrum. Undermining of the PU was assessed with the aid of gray-scale sonography (US), color Doppler US, power Doppler US, and a microvascular imaging technique employing advanced clutter suppression. Clutter suppression post-processing the study allowed for the evaluation of low-velocity microvascular flow in the undermined PU and facilitated the choice of appropriate treatment.
