Abstract
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.
