Active clinical trials for "Aneurysm"

The management and delivery of intravenous fluids during surgical operations is one of the important duties for anesthesiologists. The goal of this study was to determine if goal directed fluid therapy, titrated using the FloTrac monitor's measurement of stroke volume variation results in a decrease in the length of stay of patients undergoing open abdominal aneurysm repair.

To assess the safety and effectiveness of the Penumbra Liberty Stent System as adjunctive treatment to embolic coils for wide-neck, saccular, intracranial aneurysms in the internal carotid artery (ICA). The Liberty Stent System is an implantable device comprised of a stent and delivery system designed as an adjunct to embolic coils in the treatment of wide-neck, saccular, intracranial aneurysms. It has three components: an implant, an introducer sheath and a delivery wire assembly. The implant component is made of superelastic and biocompatible nitinol tubular material. Patients presenting with wide-neck, saccular, intracranial aneurysms in the internal carotid artery (ICA) from the cavernous segment to the carotid terminus (including the paraclinoid, ophthalmic, hypophyseal and posterior communicating segments) will receive stent assisted coiling by the Penumbra Liberty Stent with any approved embolic coils currently on the market. Wide-neck aneurysms are defined by a neck ≥4mm or a dome-to-neck ratio <2. Each patient will be followed and assessed for 2, 6 and 12 months after enrollment.

Unruptured saccular intracranial aneurysms larger than 7 mm can be treated with endovascular occlusion using detachable coils, with or without expendable stent assistance. A new endovascular technique has recently been developed, using flow diverter stents without associated coils. Clinical results already published are encouraging but have to be confirmed. Furthermore, these medical devices are expensive in comparison to the coiling strategy. The purpose of this study is to compare the clinical efficacy, safety, and cost-effectiveness of endovascular coiling and endovascular flow diversion for unrupted saccular intracranial aneurysms.

The purpose of this study is to assess the safety and effectiveness of the Pipeline™ device in the treatment of unruptured, wide-neck intracranial aneurysms.

Clinical Investigation Design A prospective, open-label, non-randomized, interventional clinical study, sponsored by Endospan Ltd. Patients will be followed-up for five years. Investigational Device The Horizon™ Abdominal Aortic Aneurysm Stent Graft System and its designated Delivery System. Purpose The purpose of the study is to evaluate the safety and performance of the Horizon™ AAA Stent Graft System for the treatment of infrarenal abdominal aortic and/or aortoiliac aneurysms. The results of this study will be used as supportive data for CE Marking submission in the European Union (EU). Objectives The primary objectives of the study are to evaluate the safety and performance of the Horizon™ AAA Stent graft System. Primary End Points Safety endpoints include proportion of patients free from device related Major Adverse Events (MAEs) within 1 month of the endovascular procedure. Performance endpoints include successful delivery and deployment of the device; and absence of the following at 1 month follow-up: aneurysm growth ≥5mm, type I or III endoleaks, stent graft occlusion, conversion to open surgery, rupture and stent graft migration. Subject population Thirty (30) patients having infrarenal abdominal aortic and/or aortoiliac aneurysms, having Iliac/femoral access vessel morphology that is compatible with vascular access techniques and devices. Treatment All patients will be treated by implantation of the Horizon™ Abdominal Aortic Aneurysm Stent graft System.

An abdominal aortic aneurysm (AAA) is a weakened and enlarged area in the abdominal aorta, which is a large blood vessel in the abdomen. Large AAAs (>55 mm diameter) carry a high risk of rupture, a surgical emergency that often leads to death due to severe internal bleeding. It has been suggested that regular exercise training might limit the rate at which AAAs develop. However, little is known about the safety and effectiveness of exercise training in these patients. This pilot study will examine the feasibility of supervised aerobic exercise training for patients with small AAAs (30 to 49 mm diameter). The investigators hypothesize that exercise training will be safe and useful for patients with small AAAs.

This study was designed to study safety and effectiveness of the Valiant Thoracic Stent Graft to treat thoracic aortic aneurysms.

To determine the safety and effectiveness of Pipeline Embolization Device for the treatment of uncoilable or failed wide-necked intracranial aneurysms (IA).

The purpose of this study is to examine, through the endpoints established in this protocol, the long-term safety and effectiveness of the Talent Abdominal Stent Graft System, in a post-approval environment.

The purpose of this study is to evaluate the performance of the GORE EXCLUDER® Bifurcated Endoprosthesis-Low Permeability in the primary treatment of infrarenal abdominal aortic aneurysms.
