Active clinical trials for "Aortic Aneurysm, Abdominal"

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

Screening for an abdominal aortic aneurysm, monitoring its growth and evaluation of its risk of rupture are based on the measure of its maximum diameter. The abdominal aortic aneurysm's treatment to prevent its rupture is recommended from a threshold of 50-55 mm in men and of 45-50 mm in women. The importance of this measure for patient management justify a specific and homogeneous protocol of measure. However, the diversity of methods of measuring the maximum diameter with scanner and ultrasound was shown. The impact of various angio-CT based measures of maximum AAA diameter, and the impact of reproducibility limits on the decision to operate have never been investigated.

A single site cross-sectional comparison of paired diagnostic imaging modalities. This study will show the sensitivity and specificity of CEUS in detecting the various types of endoleaks, in comparison to tCTA, following EVAR. It will collect data to allow comparison of diagnostic accuracy across modalities including CDU, CEUS and tCTA. It will collect time taken to perform the various types of scan, to allow healthcare costs to be calculated for each imaging modality.

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.

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.

The Vascutek Anaconda™ Stent Graft System for repair of Abdominal Aortic Aneurysms (AAA) is the subject of this observational study. 180 patients will be implanted with the Anaconda™ Stent Graft System and will be followed-up annually for 5 years post-implant. The study will satisfy the requirements of the French National Authority for Health (Haute Autorité de santé) and the data collected will be used for reimbursement renewal.

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.

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.
