Filter by:To establish the safety and effectiveness of the SEAL™ Saccular Endovascular Aneurysm Lattice system for the treatment of saccular intracranial aneurysms. The data from this study will be used to support a premarket approval (PMA) submission.
This is a preliminary randomised controlled trial comparing the use of pre-operative 3D models to select an intrasaccular flow disruptor for endovascular aneurysm cure.
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.
Rationale: Intrasaccular neck occlusion devices have been used for unruptured aneurysm without safety concerns and good occlusion rates. In the setting of a subarachnoid hemorrhage, they could improve the rate of complete occlusion without safety concerns. Aim: To explore the safety and efficacy of intrasaccular neck occlusion devices in patients with acute subarachnoid hemorrhage caused by a ruptured saccular aneurysm by a one arm prospective registry. Study outcome: The primary outcomes is the rate of complete occlusion (Raymond-Roy I) and rebleeding at one year follow-up. The primary safety outcome is rate of rebleeding during the admission.
The main objective of this study is to better estimate the rate of infectious intracranial aneurysms (IIA) in proved infective endocarditis (IE). It also aims to identify MRI markers capable of accurately predicting (or excluding) IIA; to assess the impact of the different MRI abnormalities on the outcome; to capture the real-world management of EI with neurological complications in comprehensive IE centers in France
To evaluate the efficacy and safety of the blood flow guide device manufactured by Jiangsu Changyida Medical Technology Co., Ltd. for endovascular embolization of intracranial aneurysms
Hypothesis: Correction of preoperative anemia can reduce the need for intra-/postoperative RBC transfusions and can improve surgical outcomes.
Despite the active development of surgical methods of treatment (endovascular embolization and microsurgical clipping) of cerebral aneurysms, determining the indications and method of surgical treatment of cerebral aneurysms still causes debate in many cases. To a greater extent, this concerns the treatment of unruptured aneurysms. While there are a number of randomized trials of surgical treatment of ruptured cerebral aneurysms, there is currently no published randomized trial comparing surgical clipping and endovascular embolization of unruptured aneurysms. The purpose of this study is to compare the safety and efficacy of microsurgical clipping and endovascular embolization of cerebral aneurysms (both ruptured and unruptured) in a prospective, randomized fashion.
This is a randomized, open label, multi-center, positive-controlled study, in which a total of 236 patients will be enrolled and randomly assigned to receive bivalirudin or heparin in a 1:1 ratio during coil embolization in patients with ruptured intracranial aneurysms. Procedure-related complication, mRS, Activated Clotting Time, ischemic and hemorrhagic complications, symptomatic and asymptomatic intracranial hemorrhage, death, Heparin Induced Thrombocytopenia will be evaluated during procedure, at 24hs, 7days and 30 days after.
This prospective single-center cohort study aims to identify the incidence of cognitive dysfunction after unruptured aneurysm operation and explore the influencing factors. The primary end point is the cognitive dysfunction at 6 months after operation.The features of cognitive function, mental status, neurological function recovery, and quality of life of patients with unruptured intracranial aneurysms at different time points would be analyzed.
