Active clinical trials for "Aneurysm"

This is a prospective, single-arm, multi-center post-marketing Study. The Study will commence as a single phase, with an optional second phase to follow at the discretion of the sponsor. Up to 300 eligible Subjects with small (< 4.9 mm) intracranial aneurysms, who consent to Study participation, will be treated in Phase 1 with MicroVention HyperSoft® 3D and HyperSoft® Helical coils with or without balloon remodeling or stent assistance at the discretion of the treating physician. The operator, at his/her discretion, may choose to frame the aneurysm with HyperSoft® 3D or any other bare metal coil but must finish the remainder of the aneurysm with HyperSoft® 3D and/or HyperSoft® Helical coils. At the discretion of the sponsor, additional patients, up to 300 patients total for the overall Study, with eligible aneurysms will be enrolled into Phase 2. In Phase 2, the aneurysm must be framed with a HydroFrame® or HydroSoft® 3D coil and filled/finished primarily with hydrogel coils. The intent to treat is to frame, fill and finish with all hydrogel coils. However, at the discretion of the treating physician, a bare platinum coil may be used to fill or finish, as long as a minimum of 50% (in total coil length) of hydrogel coils are used. Data will be collected on immediate and post-treatment angiographic occlusion rates (RRGS), new peri-procedural imaging-confirmed hemorrhage or ischemic stroke, neurological morbidity and mortality rates, recurrence rates, bleeding rates, retreatment rates, serious adverse events, >150 day angiographic occlusion rates (RRGS) and occlusion status. This will serve to establish the acute and sustained efficacy of EVT of small intracranial aneurysms with the specified microcoils, aided by balloon and/or stent remodeling where appropriate.

The purpose of this study is to evaluate the safety and effectiveness of the MicroVention Flow Redirection Intraluminal Device (FRED) system when used in the treatment of wide-necked intracranial aneurysms.

To evaluate the safety and feasibility of the Cordis Neurovascular Self-Expanding Stent System to facilitate endovascular coil embolization of wide neck saccular intracranial aneurysms. Cordis Self Expanding Stent for use with embolic coils for the treatment of wide-neck, intracranial, saccular aneurysms arising from a parent vessel

The purpose of this pilot study is to investigate the use of minocycline and doxycycline as medical therapy for inoperable or partially treated arteriovenous malformations (AVMs) and giant aneurysms.

The objective of this clinical study is to assess the safety and effectiveness of the Cordis Endovascular Quantum LP™ Stent Graft System.

The purpose of this study is to compare the cost effectiveness, quality of life and outcomes of the endovascular stent graft repair with the open surgical repair of abdominal aortic aneurysms.

The primary endpoint is coronary artery diameter, normalized for body surface area, 5 weeks after randomization. Secondary endpoints include duration of fever, CRP levels, and adverse events.

The optimal consensus concerning treatment of incidental small paraclinoid unruptured intracranial aneurysms (UIAs) remains controversial. The aim of this prospective study is to reveal the natural history of small paraclinoid UIAs with the goal of informing the treatment plan.

Part of interventional neuroradiology procedures for the treatment of selected cerebral aneurysms are now based on stenting. To reduce thromboembolic events, dual antiplatelet therapy (APT) combining aspirin and clopidogrel is proposed with close monitoring, since 1/3 of the patients are low responders due to variation of the biological response to clopidogrel . Ticagrelor is used by few teams but has never been evaluated in a randomized controlled trial. It could be an option for APT due to more reproducible response with less interindividual variability and reduced monitoring. The aim of this study is to demonstrate the interest of ticagrelor for the dual APT for platelet inhibition, in patients undergoing neurovascular stenting for cerebral aneurysm.

The purpose of this national observational study is to evaluate the Thoraflex™ Hybrid vascular prosthesis in the replacement of the aortic arch and the treatment of aneurysm/dissection of the descending thoracic aorta in relation to morbidity-mortality, visceral malperfusions, neurological and renal complications, endoleak and evolution of the aortic thoracic stent over time.
