Early and Midterm Outcomes of Endovascular Aneurysm Repair With Zenith Alpha Abdominal Stent-Graft: Results From a Multicenter Retrospective Tuscany Registry.

The authors describe satisfactory early and 5 year outcomes of Zenith Alpha Abdominal in elective endovascular aortic repair in the framework of a multicenter regional retrospective registry. At 5 years freedom from type I endoleak was 88.6%, and rate of endograft infections and conversions to open repair were very low. in the present study. Hot topic about about Zenith stent-graft still remains the limb graft occlusion with a 30-day overall rate of 2%, and estimated 5-year freedom from limb graft occlusion of 93.6%. Limb graft configuration did not affect limb graft occlusion rate. A standardized protocol including iliac stenting should be adopted to reduce kimb graft occlusion.
