Endotension

Endotension, also referred to as a type V endoleak, is not a true leak but is defined as continued expansion of the aneurysm sac greater than 5 mm, without radiographic evidence of a leak site.

Pathology

It is a poorly understood phenomenon but thought to be formation of a transudate due to ultrafiltration of blood by the graft membrane or unidentified leak.

Treatment and prognosis

Some centres are trialling the use of an endovascular relining technique to reduce aneurysm expansion due to endotension, or stent reinforcement can be performed.
