Establishment of Online Registration Platform for Unruptured Intracranial Aneurysms Based on 100 Regional Medical Centers in China and Population Follow-up Study

Study Overview
=================
Brief Summary
-----------------
In this study, 20 regional neurosurgery centers across the country will be included, and the study cohort will be constructed on the basis of the IARP-CP cohort.The artificial intelligence platform was used to analyze the clinical, morphological, hemodynamics, aneurysm wall characteristics and other factors of unruptured aneurysms, as well as the relationship between these factors and the risk of aneurysm instability, seek the potential risk factors, and finally establish a multi-dimensional prediction model of rupture risk of intracranial aneurysms.
