Treatment Strategies for Unruptured Intracranial Aneurysms in the Chinese Population China Treatment Trial for Unruptured Intracranial Aneurysm (ChTUIA)

Study Overview
=================
Brief Summary
-----------------
The goal of this prospective observational cohort study is to learn about treatment strategies for unruptured intracranial aneurysms in the Chinese population. The main questions it aims to answer are: To establish a cohort of patients with intracranial unruptured aneurysm and explore the optimal clinical treatment strategy. To establish clinical management path for patients with unruptured intracranial aneurysm. According to the treatment of all patients with unruptured intracranial aneurysm, they were divided into the following groups: 1. Conservative treatment group; 2. Intracranial aneurysm clipping group; 3. Coil embolization or stent-assisted coil embolization group; 4. Flow diversion group.
