Filter by:The goal of this observational study is to find out what factors contribute to a good treatment outcome in patients who have received a stent for their dilation of the main abdominal artery (abdominal aortic aneurysm or AAA). The primary goal of this study is to build a prediction model for abdominal aortic aneurysm shrinkage one year after the treatment.
A prospective, observational post-market registry collecting outcomes through a 10-year post procedure follow-up for patients treated with the GORE® EXCLUDER® Conformable AAA Endoprosthesis (EXCC Device) or the GORE® EXCLUDER® Iliac Branch Endoprosthesis (IBE Device) as a part of routine clinical practice.
Managing abdominal aortic aneurysms currently relies on diameter assessment with ultrasound. Diameter reproducibility with two-dimensional ultrasound is challenging, and requires experienced operators. A novel automatic three-dimensional ultrasound system has the potential to facilitate more precise diameter measurements than two-dimensional ultrasound. This study aimed to assess the variance of abdominal aortic aneurysm diameter measurements among ultrasound novices and experts by comparing two-dimensional ultrasound with the three-dimensional ultrasound system in a clinical setting. Ten patients under abdominal aortic aneurysm surveillance were examined by 29 ultrasound-operators: 13 experts and 16 novices. The experts were sonographers and physicians highly experienced in abdominal aortic aneurysm ultrasound, and the novices were medical students and junior residents with sparse ultrasound experience.
Prospective, randomized, multi-center study designed to evaluate the outcomes of commercially available contemporary EVAR in a real-world population. Patients will be randomized into two device cohorts and compared across the primary endpoints. Patients will be followed procedurally to discharge, at 1, 6, 12 months and annually through to 5 years (total follow-up commitment).
A retrospective cohort study of computed tomography scans of AAA patients considered for repair, in order to identify sex specific differences in abdominal aortic aneurysm (AAA) metrics and the association between anatomical differences/features of complexity and adverse patient outcome.
This multicenter, single-arm retrospective registry (chart review) is being conducted to confirm the clinical performance and safety of GORE-TEX® Vascular Grafts and GORE® PROPATEN® Vascular Graft throughout the device functional lifetime for each indication area.

This study explore AAA prevalence in OSAHS patients by ultrasound screening and try to analysis risk factors of AAA in OSAHS patients.
This study is a data linkage project within which we aim to model the impact on the NHS AAA Screening programme of a targeted approach to screening by targeting men who smoke. This in-silico study will generate a hypothetical population based on primary care datasets with known outcomes from screening (we know which men have an aneurysm and who do not) to determine the feasibility and safety of this approach.
The purpose of the post-market study is to assess the clinical outcomes, safety, and performance of the Endurant Chimney Graft Technique (Endurant Stent Graft Systems used with a balloon-expandable covered stent graft) for treatment of juxtarenal aortic aneurysms with a short infrarenal neck in a real world setting.
