Multicenter Study to Evaluate the Effectiveness and Safety of Flow-Diverting Stents for Distal Intracranial Aneurysms
Using data obtained from the treatment of intracranial distal intracranial aneurysms with flow diverter, evaluate the effecy and safety of blood flow diverter for the endovascular treatment of distal intracranial aneurysms.
• Age 18 to 80 years, any gender，Subjects who have accepted treatment with flow-diverting for distal intracranial aneurysms
• Diagnosed with an intracranial aneurysm by CTA, MRA, or DSA, with the following features: a wide neck (≥4mm), or a dome-to-neck ratio \<2, saccular, fusiform aneurysms, recurrent saccular aneurysms, and dissecting aneurysms. Locations include: the Circle of Willis and it's distal branches such as the middle cerebral artery (MCA) M1-M3 segments, anterior cerebral artery (ACA) A1-A3 segments, posterior cerebral artery (PCA) P1-P2 segments, etc. (intracranial aneurysms of the Circle of Willis and it's distal vessels).
• Subject or guardian is able to understand the purpose of study, shows sufficient compliance with the study protocol and provides a signed informed consent form
