Active clinical trials for "Aneurysm"

The study aims to investigate the applicability of intravascular ultrasound (IVUS) in the endovascular therapy of juxta-, supra- and thoracoabdominal aortic aneurysms. The focus of the study is on the intraoperative and postoperative evaluation of the geometric data of bridging stentgrafts in terms of patency, occurrence of stenosis and/or kinking.

The aim of the study is to assess if venous distension in patients with aneurysmatic arteriopathy is higher compared to patients with peripheral arterial occlusive disease (PAOD) and in controls.

International registry gathering patients with angiographically confirmed coronary aneurysm.

Study of the prevalence of Abdominal Aortic Aneurysms (AAA) (> 3 cm) in patients with echocardiography (transthoracic or) during a specific day, with cardiologists in France. This is a cross-sectional epidemiological investigation, assembling evidence from a routine ultrasound screening for AAA at the waning of echocardiograms performed during a specific day. The study will be offered a list of centers selected by the Scientific Committee in the complete list of locations being in France, the subsidiary of echocardiography Echocardiography of French Society of Cardiology. These centers will be 500 in number representative of the French centers, geographically and by type of centers.

The purpose of this study is to support the suspected expectation that Contrast enhanced Ultrasound (CUS) detects all endoleaks that have been detected by Computed Tomography (CT), and also find a number of leaks missed by CT. The investigators' primary goal is to detect no difference between CT and CUS and provide evidence that CUS is a possible alternative to CT.

The purpose of this study is to assess the prevalence and predictors of pituitary dysfunction, as well as secondary out-come in patients with traumatic brain injury or spontaneous subarachnoidal haemorrhages.

The primary objective of this study is to evaluate if the motor-evoked potentials/motor action potential amplitude ratio and motor action potential amplitude measurement are useful in detecting spinal cord ischemia during thoracoabdominal aortic aneurysms surgery. The secondary objective is to evaluate the presence of a correlation between neurophysiological changes and other factors (such as surgical maneuvers, anesthetic and physiologic changes) in order to find which factor is the most important in determining spinal cord ischemia. This study is an observational, single-center, prospective study on patients with thoracoabdominal aortic aneurysms undergoing surgical repair with intraoperative motor-evoked potentials and somatosensory evoked potentials monitoring.

The Zenith®Fenestrated AAA Endovascular Graft Clinical Study is a clinical investigation approved by the US FDA to study the safety and effectiveness of the Zenith® Fenestrated AAA Endovascular Graft in the treatment of abdominal aortic and aorto-iliac aneurysms.

This is a pilot study designed to validate our methods of recruitment, screening and data collection in the community. The project will help to establish the feasibility of the study design to lay the groundwork for a potentially larger study. The final study will allow us to estimate the incidence and prevalence of abdominal aortic aneurysm (AAA), carotid artery stenosis, and peripheral artery disease (PAD) in different geographic areas in a large urban setting, as well as determine patient access to healthcare and treatment for vascular disease as related to geographic and racial differences.

To clarify whether amnesia after treatment of anterior communicating aneurysm (ACoA)is related to infarcts caused by occlusion or damage of the perforating artery of the ACoA, we used 3.0-T 3D high resolution MR imaging to identify and localize infarcts in patients with amnesia following treatment of ACoA aneurysm.
