Introduction: Aim is to study the poor prognostic determinants for patients undergoing iliac artery angioplasty and stenting. Material and Methods: It is a Prospective observational study done in forty patients who has undergone iliac artery angioplasty and stenting for lower limb ischemia. Results: 15% had reocclusion of lesion, 7.5% required reintervention and 7.5% underwent major limb amputation .These three were considered major negative impact conditions. These were found in majority of patients with renal insufficiency, critical limb ischemia, smoker and drug defaulters. Conclusion: Thus poor prognostic determinants in the study were renal insufficiency, critical limb ischemia , smoker and drug defaulters.
