Active clinical trials for "Aortic Aneurysm, Abdominal"

"Pilot randomized prospective clinical study of the effectiveness of the use of artificial intelligence in determining "safe" clamping zones in the surgical treatment of abdominal aortic aneurysms."

This is an intersectional and interdisciplinary screening program in Viborg Municipality, including 67 years old citizens. This observational study will estimate the cost-effectiveness of a combined screening program for the following conditions: Abdominal aortic aneurysm, peripheral arterial disease, carotid plaque, hypertension, arrhythmia, and type-2-diabetes. Furthermore, the incidence of the outlined conditions will be described and so will the result of the intervention initiated (secondary medical prophylaxis, smoking cessation, introduction to nutritionally deficient diet etc.)

This study is set up to assess the feasibility and safety of the clinical procedure using AneuFix in a prophylactic setting at the time of EVAR endograft implantation.

This study is a multi center double-blinded randomized controlled superiority trial, comparing the effects on postimplantatrion syndrome of a single preoperative dose of dexamethasone vs. standard treatment in endovascular aneurysm repair. Participating researchers must be vascular surgeons or vascular anesthesiologists certified by national entities. Recruitment is expected to begin in the second semester of 2023. The trial will follow the ICH-GCP guidelines and national and international legislation and reporting will be performed according to CONSORT 2010 guidelines. Site inclusion requires hospital ethics committee approval. Written informed consent is mandatory for all patients and the information and consent forms must be approved by Institutional Ethics Committee.

The main objective of this study is to utilize Magnetic Resonance Elastography (MRE) to determine tissue stiffness of abdominal aortic aneurysms (AAA). For patients with AAA, MRE is a more sensitive and superior method of determining the risk for rupture of AAA based on stiffness estimates when compared to the current, crude method of assessing risk based on measurement of the diameter of the aneurysm. The investigators will also validate the stiffness estimates against gold standard i.e. mechanical testing and histopathology only AAA patients undergoing AAA surgery.

The main objective of the CARE-ANEURYSM project is to evaluate inflammation and clotting abnormalities in patients with aneurysmal coronary artery disease in relation to patients with abdominal aortic aneurysm or coronary artery disease (acting as controls).

This is a Prospective Registry study to collect imaging and clinical data both on patients with aortic aneurysm disease undergoing serial monitoring and on patients pre and post-endovascular repair, using ViTAA (The Sponsor) aortic mapping technology.

We study differen t endovascular techniques as an alternative to surgical reconstruction to repair AAAS regarding ; success rates, 30-day mortality, endoleak events secondary intervention rates

An abdominal aortic aneurysm (AAA) is a pathological dilatation of the aorta in the belly which can rupture leading to bleeding within the belly. To prevent rupture elective surgery can be performed. Endovascular repair (EVAR) is a surgical intervention whereby a stent is inserted into the AAA to prevent it from further growth and rupture. Standard AAA management has several drawbacks. To start: maximum AAA diameter is used to determine upon timing of elective repair but is imprecise in predicting the risk of rupture resulting in an unmet clinical need. Secondly, EVAR outcome and complication occurrence remain unpredictable due to poor prediction ability of computed tomography (CT) and ultrasound (US) utilised in the follow-up protocol. Lastly, patients and physicians are being repeatedly exposed to cumulative radiation toxicity. All these drawbacks could be solved by trading the standard imaging modalities by magnetic resonance imaging (MRI). Within the MARVY, advanced MRI techniques are used to find out if standard imaging techniques could be replaced by MRI in three phases of the AAA management (surveillance, surgery planning and post-operative follow-up). The two most important MRI techniques that will be used are 4D flow MRI and dynamic contrast enhanced (DCE) MRI which give respectively information about the blood flow within the AAA and perfusion of the aortic wall.

AAA characteristics are traditionally measured with computed tomography angiography (CTA), however, three-dimensional ultrasound (3D US) is emerging as a novel imaging method for AAAs. With the use of a US contrast agent, the AAA thrombus can also be distinguished from the lumen on the 3D scans. This enables 3D visualization of the AAA and its thrombus without the need for harmful radiation and nephrotoxic contrast agents, as opposed to CTA. In in vitro measurements, 3D US has already been shown to have clinically acceptable error rate with AAA diameter and volume measurement. However, it is unclear whether this is also applicable to in vivo measurements. Therefore, the aim of this prospective study is to compare preoperative 3D US AAA characteristics as measured by 3D US with contrast enhancement (3D CEUS), 3D US without contrast enhancement (3D non-CEUS) and CTA.
