RecruitingDevice studyUse of Thermal Imaging Camera to Assess Perfusion Before and After Vascular InterventionThis is a preliminary prospective observational study measuring change in lower extremity temperature in response to revascularization procedure. The main question this study aims to answer is: \- Are temperature measurements from a forward looking infrared (FLIR) camera of the lower extremity useful in predicting outcome of revascularization procedures?
