Active clinical trials for "Aortic Aneurysm, Abdominal"

The investigators want to measure the degradation of the endothelial glycocalyx before and after clamping the aorta, in patients operated for a abdominal aortic aneurism.

The purpose of this registry is to obtain case reports of physician experience with the Spiral-Z® graft under routine clinical care.

Registry for Endovascular repair of abdominal aortic aneurysm performed primarily by Interventional Cardiologists

It has been estimated that 80% of deaths from abdominal aortic aneurysms results from rupture. Endovascular Aneurysm Repair (EVAR) has been applied to RAAA (Ruptured Abdominal Aortic Aneurysm) patients with reports of improvements. Despite the use of EVAR, patients have developed complications with lung and kidney function. This study will investigate certain biochemical processes that will potentially reduce these complications. Knowledge gained from this study may also be used to further research in this field through larger studies.

The vascular surgery is a highest risk procedure when considering postoperative complications associated with the cardiovascular system. The leading clinical presentation is acute hemodynamic decompensation. However, one of the possible pathomechanisms might be repolarization disturbances. Many of perioperative risk factors of cardiac complications are modifiable. The identification may help in the global perioperative risk reduction. Aim: The aim of the study was an identification of the factors which may release clinically overt repolarization disturbances. Methods: The study group consisted of 100 patients, diagnosed with abdominal subrenal aortic aneurysms or peripheral arterial disease scheduled for an elective "open" vascular surgery procedure. The authors investigated whether age, gender, comorbidities or some perioperative factors (including hemodynamic, metabolic or genetic) were related to the occurrence of clinically concealed repolarization disturbances or clinically disclosed cardiac complications in postoperative time up to 30 day and one year after vascular surgery procedure.

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.

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 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.
