Active clinical trials for "Aortic Aneurysm, Abdominal"

This study aims to determine whether advanced MRI sequences can provide robust and clinically relevant information about abdominal aortic aneurysms (AAAs). The MRI sequences will study outcomes related to blood flow inside AAA, microvasculature of the AAA vessel wall and intraluminal thrombus inside AAA. Robustness of these MRI sequences will be determined with testing of feasibility and reproducibility. Clinical relevance will be assessed by studying the association between the primary outcomes and disease severity. Disease severity will be expressed by AAA diameter. It is our hypothesis that these parameters are significantly related to disease severity and may therefore be future markers of disease progression.

Complex aortic aneurysms involving major branches have been difficult endovascularly. The primary purposes of this study is to evaluate the safety, feasibility, and efficacy of multiple overlapping uncovered stents in treating aortic aneurysm while preserving major visceral branches, including the celiac artery (CA), superior mesenteric artery (SMA) and renal artery (RA).

Comparison of non-invasively obtained central blood pressure using SphygmoCor and invasively recorded central blood pressure in patients with an AAA that will be treated with EVAR.

The primary aim of the study is to determine if the evolutivity of global and segmentary captation of FDG-F18, which can be measured in the wall of abdominal aorta aneurysm, is predictive of the 9 month evolution of diameter and volume of the aneurysm, measured globally and segmentary in angioscan.

The purpose of this study is to investigate the prevalence of abdominal aortic aneurysms (AAA) among male patients with transient ischemic attack (TIA) symptoms. Ethiology of AAA is known to be common with atherosclerotic arterial diseases (coronary artery disease, peripheral artery disease and carotid artery disease), so the hypothesis is that AAA should be more common among these TIA patients, thus making screening of these patients (for AAA) more cost-efficient. Study will be carried out as a prospective screening study. Data will be collected in North Karelia Central Hospital within one year. All male patients with TIA symptoms will be recruited for the study and screened for AAA with ultrasound.

Prospective randomized comparison between endovascular procedures performed with iodinated contrast or carbon dioxide as intraarterial contrast.

To determine the prevalence of Abdominal Aortic Aneurysm (AAA) in the Spanish men over 60 years through a screening program in Primary Health Care using a hand-held ultrasound and to analyze the relationship between cardiovascular risk factors and cardiovascular disease in patients with AAA.

Cumulative radiation dose, cost, contrast induced nephrotoxicity and increased demand for computed tomography aortography (CTA) suggest that duplex ultrasonoraphy (DU) may be an alternative to CTA-based surveillance. The investigators compared CTA with DU during endovascular aneurysm repair (EVAR) follow-up. Patients undergoing EVAR have radiological follow-up data entered in a prospectively multicenter database. The gold standard test for endoleak detection was CTA. DU interpretation was performed independently of CTA and vice versa.

The ARCHYTAS Registry is a long-term, global, multicenter, non-randomized, prospective, registry designed to collect "on-label" data in real world clinical settings on patients undergoing endovascular repair with the latest generation Aorfix™ AAA Flexible Stent Graft System. Registry data will augment existing data from ongoing and prospective Aorfix™ clinical trials for the purposes of publication, general product development and quality measures.

The purpose of this study is to determine the prevalence of abdominal aortic aneurysm (AAA) and abdominal aortic atheromatosis (AA-At) using a hand-held ultrasound by a general practitioner in Primary Health Care.
