Background: Perform literature review to analyze current practices in imaging patient with peripheral arterial disease (PAD) and examine patterns in our practice in order to assess whether a lower extremity computed tomography angiography (CTA) in addition to digital subtraction angiography enhanced the assessment of vessel calcification, percentage of stenosis, and affected outcomes in patients with PAD.
Methods: The study included patients who underwent lower extremity imaging and were followed up to 12 months. This population was divided into cases who had both an angiogram and CTA performed within 30 days (n = 20), and controls who underwent angiography only (n = 19).
