The Incidence, Risk Factors, and Outcomes of Contrast-Induced Nephropathy In Patients With Critical Limb Ischemia Following Lower Limb Angiography.

Intra-arterial digital subtraction angiography (DSA) is commonly used for the diagnosis and treatment of patients with critical limb ischemia (CLI). The aim of this study was to analyze the incidence of contrast-induced nephropathy (CIN) in patients with CLI and to assess their outcomes. Between May 2013 and May 2014, a prospective and observational study was conducted with 107 patients admitted exclusively for CLI treatment.
