Early Feasibility Study of the RelayBranch Thoracic Stent-Graft System
Thoracic Aorta AneurysmAneurysm2 moreThe purpose of this study is to conduct an early clinical evaluation of the Relay Branch System, which will provide initial insight into the clinical safety and function of the device. This Early Feasibility Study (EFS) will assess the safety and effectiveness of the device at the index procedure and at 30-day follow-up. The study will evaluate the delivery and deployment of the device, patency of branches and branch vessels, and exclusion of the aortic pathology. The data will help determine if modifications need to be made to the device, the procedural steps, operator technique, or the indications for use.

Appraising the Embolization of Aneurysms Using Balt Optima™ Coil System (APPLY Study)
AneurysmIntracranial Aneurysm4 moreIn recent years, many developments have been made to the tools and techniques used to treat IAs via endovascular intervention. Specifically, to the detachable coils themselves. In March 2018, the US Food and Drug administration granted Balt USA 510(k) clearance for the Optima Coil System™. Earlier this year, the list of devices included within the system has expanded to include OptiMAX Complex Super Soft and Complex Soft coils. It consists of coils that come in Standard, Soft and Super Soft profiles and allows for instant detachment from the pusher. The APPLY study is a prospective, single-center investigator-initiated study meant to assess the use of the Balt Optima™ Coil System. The site is looking to enroll approximately 30 subjects over the course of two years. The Optima Coil System™ is commercially available in the United States as such this study is looking for real-world data.

Enhanced Versus Standard Blood Pressure Lowering on Intracranial Aneurysm Rupture or Growth China...
Unruptured Intracranial AneurysmThe goal of this randomized controlled trial is to evaluate the benefits and safety of controlled hypotension in Chinese patients with unruptured intracranial aneurysms(UIA). The main questions it aims to answer are: To provide high-level evidence of the benefits and safety of controlled hypotension in patients with UIA. To provide evidence-based medical evidence for blood pressure control of patients with UIA in neurosurgery, and promote the progress of accurate individual management of patients. In this study, the main intervention is enhanced blood pressure lowering in patients with UIA. All Patients will be randomly assigned to either the standard blood pressure lowering (SBPL) group or the enhanced blood pressure lowering (EBPL) group.
Barrow Ruptured Aneurysm Trial
Ruptured Cerebral AneurysmSubarachnoid Hemorrhage (SAH)With evolving endovascular technologies there is a growing debate centered on the relative safety and efficacy of the currently accepted alternatives for the treatment of ruptured cerebral aneurysms in the face of acute subarachnoid hemorrhage (SAH). The purpose of this study is to compare the safety and efficacy of microsurgical clipping and endovascular coiling of acutely ruptured cerebral aneurysms in a prospective, randomized fashion.
Minocycline for Aneurysmal Subarachnoid Hemorrhage (MASH)
AneurysmRuptured4 morePrevious work has demonstrated patients presenting with ruptured aneurysms that develop radiographic and clinical vasospasm have a higher permeability of the blood brain membrane. Matrix metalloproteinase 9 (MMP9) has been studied and recently implicated in both the pathogenesis of the blood brain barrier breakdown and vasogenic edema of ischemia strokes, and is suggested to be an accurate biomarker to predict the onset of cerebral vasospasm after subarachnoid hemorrhage. The therapeutic benefit of minocycline, an MMP9 inhibitor, has been investigated in ischemic stroke population, however its role in the treatment of cerebral vasospasm from ruptured aneurysms remains unknown. Our project has two main goals: to further confirm MMP9 has a reliable biomarker for the onset of cerebral vasospasm, and secondarily to investigate any possible therapeutic benefit that minocycline has in the vasospasm population. Vasospasm continues to be one of the major contributors of morbidity and mortality in the ruptured aneurysm population, and close monitoring of the neurologic exam during the 'vasospasm window' usually requires two weeks in the intensive care unit in most academic settings. As such, if we are better able to predict which patients are at risk of developing vasospasm based on MMP9 levels, we will be better able to anticipate the need for intervention and therefore mitigate the risk of vasospasm induced ischemic strokes, ultimately resulting in better outcomes in the ruptured aneurysm population. Further, if we are able to identify minocycline as a therapeutic agent to deter, or lessen the severity of vasospasm, we can possibly improve neurologic outcomes, decrease hospital stays, ultimately providing an improved and more cost-effective treatment strategy to our patients.
