Clinical Trial Summary

In recent years, researches on the natural history and risk factors of intracranial unruptured aneurysms have become a hot topic at home and abroad. However, risk factors for aneurysm rupture is still unclear yet. The investigators' preliminary study focused on constructing a rupture risk prediction system for intracranial unruptured aneurysm in the investigators' single center. The investigators' result showed that three significant factors (sex, abnormal serum tumor necrosis factor (TNF)-α and coincidence of thin-walled regions (TWR) and normalized wall shear stress (NWSS)) stood out by using logistic regression to explore the rupture risk factors of intracranial unruptured aneurysms, which could help guide the clinical treatment of intracranial unruptured aneurysms. This study is to evaluate and improve the rupture predict model of intracranial unruptured aneurysm in multi-neurosurgical centers.


Clinical Trial Description

In recent years, researches on the natural history and risk factors of intracranial unruptured aneurysms have become a hot topic at home and abroad. However, risk factors for aneurysm rupture is still unclear yet. The investigators' preliminary study focused on constructing a rupture risk prediction system for intracranial unruptured aneurysm in the investigators' single center. Four aspects for unruptured aneurysms were collected: (1) Patients' basic demographic characteristics; (2) Reconstruction of intracranial unruptured aneurysm wall with 7-Tesla MRI, and explore the technical parameters of 7-Tesla high-resolution black blood MRI scanning intracranial aneurysm wall (0.5 mm isotropic resolution), as well as assessing the relationship between aneurysm wall enhancement (AWE), thin-walled regions (TWR), and hemodynamic parameters and their relationship to aneurysm development; (3) Using hydrodynamics to explore the hemodynamic parameters of intracranial unruptured aneurysms, explore new hydrodynamic parameters and screen rupture-related risk factors; (4) The use of single-cell RNA sequencing technology to explore the infiltration of immune cells in the aneurysm wall tissue of intracranial unruptured aneurysms. Based on the above research results, three significant factors (sex, abnormal serum TNF-α and coincidence of TWR and normalized wall shear stress (NWSS)) stood out by using logistic regression to explore the rupture risk factors of intracranial unruptured aneurysms, which could help guide the clinical treatment of intracranial unruptured aneurysms. This study is to evaluate and improve the rupture predict model of intracranial unruptured aneurysm in multi-neurosurgical centers. ;
