Quantitative digital subtraction angiography for identifying the risk factors of incomplete occlusion in intracranial aneurysms with branch incorporation after flow diverter treatment.

ABSTRACT:

Background

Flow diverter (FD) treatment has shown promising results in managing intracranial aneurysms (IAs), achieving high rates of complete occlusion. However, in cases involving branch incorporation, incomplete occlusion remains a challenge, adversely influencing long-term treatment outcomes. The mechanisms underlying the incomplete occlusion in IAs with branch incorporation have not been fully clarified. Therefore, the objective of this study was to assess the value of quantitative digital subtraction angiography (QDSA) in predicting incomplete occlusion of IAs with branch incorporation following FD treatment.

Methods

We retrospectively analyzed data from 111 patients with 113 IAs involving incorporated branches who were treated with FDs between January 2016 and Decembe
