Pattern of vascular involvement in patients with critical limb ischemia secondary to TAO

Introduction: Thromboangiitis obliterans (TAO) is smoking realted vasculopathy. Though traditionally described to be only a medium and small vessel disease, we do see patients with a more proximal pattern of disease in clinical practice. We undertook this study to relook at the site of vascular involvement in patients with critical ischemia secondary to TAO in our population. Materials and methods: We performed a retrospective analysis of...
