Abstract

Objectives To collect specific literature on type Ib endoleak after aorto-iliac endografting for abdominal aortic aneurysm, reporting data on diagnosis, treatment, and follow-up results. Methods Publications about type Ib endoleak after aorto-iliac endografting for abdominal aortic or iliac aneurysm were searched in PubMed, Web of Science, and Scopus. Considered studies were in English and published until 3 November 2016. Research methods and reporting were performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Inclusion criteria were: (1) reporting on abdominal aortic or iliac aneurysm as primary diagnosis; (2) reporting on distal endoleak after aorto-iliac endografting.
