Key result
The authors propose two new categories of endoleak after endovascular aneurysm repair: type III (fabric tears, graft disconnection) and type IV (graft wall porosity).
This document establishes the definitions for Type III and Type IV endoleaks, providing a standardized nomenclature for complications following endovascular aneurysm repair.
Standardizes endoleak categorization after EVAR; leaves open effects on management and trial endpoints.
In this document the authors continue to refine their seminal categorization of endoleak, a major complication of endovascular aneurysm repair. In addition to type I (related to the graft device itself) and type II (retrograde flow from collateral branches) endoleak, they propose two new categories: endoleak due to fabric tears, graft disconnection, or disintegration would be classified type III, and flow through the graft presumed to be associated with graft wall “porosity” would be categorized as type IV endoleak.
