Early Postprocedural Susceptibility-Weighted Imaging and Vessel-Wall Imaging For Prediction of Complications After Flow-Diversion Treatment

Purpose: Examination of microangiopathic changes that may develop after flow-directed stenting of intracranial aneurysms with susceptibility-weighted imaging (SWI), and vessel wall imaging (VWI) of vessel wall inflammation that may be associated with stenosis in the stented vessel and rupture of the aneurysm.Methods: SWI and VWI examinations will be performed before and after treatment in patients who are planned for flow-directing aneurysm treatment. Clinical follow-up of the cases will be performed during the first 3 months post-procedure. At the end of the 3rd month, SAG and DDG findings related to and unrelated to intracranial hemorrhage will be detected by control imaging.
