Circumferential Aneurysm Wall Enhancement Predicts Recanalization After Stent-Assisted Coiling in Small Unruptured Intracranial Aneurysms.

ABSTRACT:

Background

Circumferential aneurysm wall enhancement (CAWE) on high-resolution vessel wall imaging (HR-VWI) as a vessel wall inflammation marker is associated with unruptured intracranial aneurysms (UIAs) instability and recanalization after endovascular treatment. This study evaluates the association of CAWE with recanalization of small UIAs (< 10 mm) treated with stent-assisted coiling (SAC) or coiling alone and aims to develop a prediction model for recanalization based on CAWE.

Methods

We analyzed patients with small saccular UIAs undergoing 3T HR-VWI and treated with SAC or coiling alone between October 2018 and May 2024. A four-grade scale assessed aneurysm wall enhancement (none, focal thick wall enhancement, thin CAWE, and thick CAWE). The aneurysm-to-pituitary stalk
