Active clinical trials for "Aortic Aneurysm, Abdominal"

An abdominal aortic aneurysm (AAA) is an enlargement or ballooning of the main artery supplying high pressure blood from the heart to the body. AAAs may continue to stretch until they burst (rupture) causing 7000 deaths per year in the United Kingdom (UK); 2.1% of all deaths in men over 65. Planned repair before rupture is critical and the National AAA Screening Programme (NAAASP) is being introduced to identify AAAs in men before rupture. Screening will identify over 9000 men per year with a previously undiagnosed AAA. More than 90% of screen detected AAAs are small, do no require repair, enter ultrasound follow-up (surveillance) and may benefit from exercise to improve fitness before repair. Over 4000 elective AAA repairs per year are performed in the UK and it has been suggested that exercise training and weight loss may reduce mortality and complications of AAA repair. This pilot study will examine the feasibility of supervised exercise training for patients with AAAs and determine the optimal duration of training to achieve worthwhile improvements in fitness.

This is an EU sponsored trial and independent of the US trial registered under Clinicaltrials.gov ID NCT02009644. The purpose of this registry is to gather clinical data on the safety and performance of the TREO Stent-Graft in patients with infrarenal abdominal aortic aneurysms. The registry is part of TREO's EU post-market surveillance plan providing long-term systematic clinical follow-up.

EVAR continues to evolve as a treatment option for AAA. New devices which are specifically designed to perform adequately across the spectrum of potential anatomic presentations for infrarenal EVAR are needed. The Department of Vascular Surgery at Catharina Hospital Eindhoven, The Netherlands initiates the EXCeL Registry. This study will assess the safety and effectiveness of the GORE® EXCLUDER® Conformable AAA Endoprosthesis (CEXC Device) in patients who meet the IFU anatomic criteria (≥15mm proximal neck length and ≤90˚ proximal neck angulation; and ≥10mm proximal neck length and ≤60˚ proximal neck angulation) and in patients with challenging anatomic presentation that may present outside the IFU anatomic criteria. Successful outcomes from this study will provide evidence to support the CEXC Device as an option for expanding EVAR to a broader patient population with more challenging anatomic presentations.

The primary study objective, at this time, is to follow out to 5 years post implant the safety of already enrolled subjects who were treated with the UniFit Aorto-uni-iliac (AUI) Endoluminal Stent Graft (the "study device") for the repair of abdominal aortic aneurysms (AAAs).

The purpose of the study is to describe Sodium Fluoride uptake (using Positron Emission Tomography-Computed Tomography - PET-CT) following Endovascular Aneurysm Repair (EVAR) and to determine whether Sodium Fluoride PET-CT can predict the development of endoleaks.

Inflammation of the blood vessel plays an important role in the development and growth of a dilated abdominal aorta. An elevated blood pressure leads to an increase in inflammation, therefore blood pressure lowering is an important part of the treatment of patients with a dilated abdominal aorta who also have an elevated blood pressure. In the investigators study the investigators compare the anti-inflammatory effects of 2 different blood pressure lowering strategies. The investigators hypothesize that both strategies will decrease inflammation, however the investigators believe the total decrease of inflammation depends on the type of blood pressure lowering medication used.

This project is to determine the safety and explore the effectiveness of allogeneic (not cells of the participant but those of another human) mesenchymal stromal cells (MSCs) in decreasing inflammation and possible enlargement of the participants' abdominal aortic aneurysm. Participants will be selected as a possible subject because of an abdominal aortic aneurysm discovered on the ultrasound or computed tomographic ("CT") scan requested by the participants' doctor. The purpose of this study is to collect information that will be used to determine if MSCs can be used to decrease inflammation and possibly slow down enlargement of the participants' aneurysm. The investigators will also be collecting blood samples to study special inflammatory cells that cause aneurysms as well as asking participants to have a "PET" (positron emission tomography) scan that can measure inflammation directly in the participants' aneurysm.

The purpose of this study is to demonstrate that the Endurant Evo Abdominal Aortic Aneurysm (AAA) stent graft system is safe and effective for endovascular treatment of infrarenal abdominal aortic or aortoiliac aneurysms.

This post market registry consists of a retrospective and a prospective part. The first part is a retrospective registry of all implanted IBE devices of Gore in the Netherlands after CE mark was obtained, to get an initial insight on the feasibility and safety of this procedure. The second part is to prospectively register all data on implanted IBE Gore devices, in order to gain more robust data on the efficacy of the device in maintaining hypogastric artery patency.

The purpose of this trial is to evaluate the safety and effectiveness of the Endurant Evo AAA (Abdominal Aortic Aneurysm) Stent graft system for endovascular treatment of subjects with infrarenal abdominal aortic or aortoiliac aneurysms.
