To explore the usefulness of SFDI in the assessment of revascularization pre and post intervention
Patients of age 21 years and above with diabetes and undergoing lower limb arterial angioplasty
Willingness to participate in the study and undergo foot physiological assessments using SFDI
Mentally incompetent, younger than 21 years of age, prisoners, pregnant or breastfeeding women
Patients unable to provide informed consent
Any medical condition which makes the candidate an inappropriate subject for study participation, in the investigator's judgment
Single group
SFDI
Other interventionSFDI imaging is performed on both treated and untreated limb.
Change in perfusion measured by tissue oxygen saturation
Change in perfusion is assessed by level of tissue oxygen saturation measured pre and post revascularization to evaluate the usefulness of SFDI in the assessment of revascularization pre and post intervention.
Compare SFDI measurements to Toe Pressure
Toe Pressure measurements are done pre and post-op and compared against SFDI values obtained.
