Active clinical trials for "Aneurysm"

The primary objective of this retrospective study is to determine the incidence of important safety outcomes in patients who have undergone Pipeline Embolization Device placement for intracranial aneurysms (IAs). This study does not effect patient care, simply it is designed to observe and capture information from numerous hospitals. Data collection will be initiated starting March 2012 and continue until approximately April 2017.

This proposal is for the pilot study that will inform the conduct of a larger prospective randomized controlled trial to guide perioperative work up and the cost/utility of CTCA (high definition CT coronary angiography.)

This is a prospective, controlled observational trial of patients undergoing clinically indicated cardiothoracic computed tomography (CT), including pulmonary or aortic angiography and coronary CT angiography (CCTA).

After endovascular treatment of an abdominal aortic aneurysm, lifelong imaging follow-up is needed to monitor the effectiveness of the treatment. One parameter in this follow-up is endoleak, which is leakage of blood into the aneurysm sac. The aim of this study is to investigate the value of magnetic resonance imaging using Vasovist as a contrast agent for the detection of endoleaks.

The objective of the registry is to evaluate the real world safety and performance of the CORDIS ENTERPRISE™ Vascular Reconstruction Device and Delivery System (VRD) to facilitate endovascular coil embolization of intracranial aneurysms.

To compare the aortic pulse profile before and after stent-graft implantation to prove that endovascular AAA repair using non-compliant stent-graft changes the aortic pulse profile.

This project seeks to determine if certain anatomic factors, specifically tortuous and non-conformable iliac arteries, may predict device complications, including seal zone failure, type III endoleak, and occlusion. Approximately 400 subjects from 5 academic centers across the United States, Europe, and Asia will be included in this study. Various markers of pre- and post-treatment iliac anatomy will be measured using CT imaging, and clinical events will be reported by academic centers. The relationship of imaging data to patient demographics will then be assessed alongside anatomic and demographic predictors of non-conformability.

Abdominal aortic aneurysm (AAA) repairs registered in the hospitals administrative database of the National Health Service from 2000 to 2015 were retrospectively analyzed regarding demographics (age and gender) and type of repair (open surgery [OS] or endovascular repair [EVAR]). Rate and mortality were compared among three time periods: 2000-2004, 2005-2009 and 2010-2015.

This study will assess the long term safety and performance of the GORE® VIABAHN® Endoprosthesis for the treatment of patients with Popliteal Artery Aneurysms.

The primary objectives of the LIFE Study are to demonstrate the clinical and cost benefits associated with using the Ovation® Abdominal Stent Graft Platform under the least invasive conditions defined in the Fast-Track EVAR protocol. The key elements of the Fast-Track EVAR protocol include: appropriate patient selection, bilateral percutaneous access, no general anesthesia, no ICU admission post procedure, and next day discharge.
