Using Spatial Frequency Domain Imaging to Assess Foot Revascularization in Diabetic Patients Before and After Angioplasty

What this Trial Is About

Diabetes is a widespread chronic condition that leads to high risks of cardiovascular problems and lower limb amputations. This research explores how Spatial Frequency Domain Imaging SFDI, a noninvasive optical method, can assess blood flow changes before and after lower limb revascularization procedures like angioplasty in diabetic patients. The trial aims to determine if SFDI can provide objective feedback to predict outcomes and aid early intervention to save limbs. Participants will undergo SFDI imaging on both the treated and untreated feet, focusing on the heel and pad areas. Imaging is done before and after the angioplasty procedure on the same day to capture changes in tissue oxygen saturation and hemoglobin. This pilot study involves 15 diabetic patients having lower limb arterial angioplasty. During the study, participants will have noninvasive foot assessments using SFDI to monitor tissue oxygen levels and blood flow. Researchers will compare these imaging results with toe pressure measurements to evaluate changes in perfusion caused by angioplasty. The primary measure is the change in tissue oxygen saturation immediately before and after the procedure. The overall participation lasts around the intervention day with imaging assessments pre- and post-operation.
