Summary: the goal of this clinical trail is to evaluate the efficiency and safety of intracranial aneurysm assistive software in the preoperative assessment. The trail is designed as retrospective, multicenter, controlled clinical trail. Collecting probable cases images retrospectively according to inclusion criteria and exclusion criteria strictly. Controlling bias strictly, to make sure the efficiency an...

Summary: The purpose of the study is to assess the safety and effectiveness of the Pipeline™ Flex Embolization Device with Shield Technology™ in the treatment with acutely ruptured intracranial aneurysms.

Summary: The Researchers are trying to test a MR imaging method for detection of Cerebral Spinal Fluid (CSF) flow in the brain to help diagnosis and better understand diseases that affect brain function.

Summary: To assess safety and efficacy of p64 MW HPC Flow Modulation Device under single antiplatelet therapy compared to p64 MW Flow Modulation Device under dual antiplatelet therapy.

Summary: The study is an observational prospective evaluation of an approved and unchanged clinical management, evaluating different diagnosis methods to assess brain perfusion in patients with an aneurysmal or AVM-related intracranial hemorrhage

Summary: A post-market registry evaluating ruptured/unruptured aneurysms treated with MICRUSFRAME and GALAXY coils

Summary: Post market surveillance registry

Summary: In this project the investigators study the safety and efficacy of the pipeline embolization device with vantage technology in treatment of unruptured brain aneurysms

Summary: Comparison of duration of dual antiplatelet therapy after stent-assisted coiling of unruptured intracranial aneurysms

Summary: Intracranial atherosclerosis (ICAS) accounts for 10 to 40%, depending on ethnicity, of the 700,000 ischemic strokes in the United States every year. The annual rate of recurrent stroke in patients with optimally treated ICAS remains more than twice the average of other stroke etiologies (12.5% vs. 5). A robust literature has established that vessel wall magnetic resonance imaging (vwMRI) of extrac...

Background: Intracerebral hemorrhage (ICH) accounts for 16-19% of all strokes in Western Europe and contributes profoundly to mortality and disability. Thirty-day case fatality is 40% and of those surviving, only few gain independence. Except for stroke unit care and possibly early blood pressure lowering, there is currently no treatment of proven benefit. Surgical treatment has so far not been proven effecti...

Summary: Giant cell arteritis (GCA) is the most frequent vasculitis in patients above 50 years of age. The disease has limited mortality, mostly due to the development of aortic aneurysms, leading to dissection and rupture. The probability to develop this complication is 17 x higher at the level of the thoracic aorta and 2,4 x at the level of the abdominal aorta in patients with GCA when compared with a co...
