Risk Factors for Incomplete Occlusion in Patients with Small Intracranial Aneurysms (<7 mm) after Flow-Diversion Treatment: A Multicenter Experience.

ABSTRACT:

Introduction

The indicator of flow diverters (FDs) received approval extension for small (<7 mm) unruptured intracranial aneurysms (UIAs). However, the factors related to aneurysm occlusion remain unclear. Thus, we conducted a multicenter analysis to explore the risk factors for incomplete occlusion (ICO) following FD implantation for small UIAs.

Methods

We retrospectively reviewed patients from 5 comprehensive hospitals in China with small UIAs treated with either Pipeline or Tubridge between September 2018 and September 2022. Baseline data were prospectively collected at admission. The relationship between baseline characteristics and occlusion status was analyzed, and multivariate logistic regression models were performed to identify the independently related factors.
