简要总结
This is a registry study on a multidimensional prediction model for rupture risk of unruptured intracranial aneurysms in China.
详细描述
This subsequent program China Intracranial Aneurysm Project - 2 (CIAP-2) will comprise screening of 500 patients from the UIA cohort (CIAP-1) and focus on hemodynamics factors, high resolution magnetic resonance imaging (HRMRI), genetic factors and biomarkers. Possible risk factors for rupture of UIA, including genetic factors, biomarkers, HRMRI, and hemodynamic will be analyzed. The first project of the China Intracranial Aneurysm Project (CIAP-1: Chaired by the Department of Neurosurgery, Tangdu Hospital, Fourth Military Medical University, Xi'an, Shaanxi, China) will establish a prospective cohort of 5000 patients with UIA from 20 centers in China, and collect baseline information for each patient. Multidimensional data will be acquired in follow-up assessments. Statistically significant clinical features in the UIA cohort will also be analyzed and integrated into this model for predicting risk of UIA rupture. After the model has been set up, the resultant evidence-based prediction will be used to provide a preliminary theoretical basis for the treatment of aneurysms at high risk of rupture.
