2024年10月4日 · Abdominal aortic aneurysms (AAA) are focal dilatations of the abdominal aorta measuring 50% greater than the proximal normal segment or >3 cm in maximum diameter. They can be confined to the abdominal aorta or continue from the thoracic aorta as part of a thoraco-abdominal aneurysm (TAAA).

2011年4月10日 · The majority of infrarenal abdominal aortic aneurysm (AAA) repairs in the United States are performed with endovascular methods. Baseline aortoiliac arterial anatomic characteristics are fundamental criteria for appropriate patient selection for endovascular aortic repair (EVAR) and key determinants of long-term success.

2005年6月23日 · Abdominal aortic aneurysm (AAA) sac shrinkage after endovascular aneurysm repair (EVAR) is considered to be evidence of clinical success. Exclusion of the sac from systemic pressure is the likely cause of shrinkage.

2011年6月21日 · Independent predictors of AAA sac enlargement included endoleak, age ≥ 80 years, aortic neck diameter ≥ 28 mm, aortic neck angle >60°, and common iliac artery diameter >20 mm. Conclusion: In this multicenter observational study, compliance with EVAR device guidelines was low and post-EVAR aneurysm sac enlargement was high, raising concern ...

Of 7659 patients with abdominal aortic aneurysms (AAAs), 94% (7188) had fusiform and 6% (471) had saccular AAAs. Significantly more patients with saccular AAAs presented acutely with AAA maximum diameter of less than 5.5 cm (25% vs 8%) and …

In this study, we investigated EVAR cases to clarify influential factors of aneurysmal shrinkage and enlargement. Methods: 148 consecutive cases before the introduction of CE were retrospectively reviewed based on the presence of PT2EL (persistent type 2 endoleak) and change in sac diameter after EVAR by multivariate analysis.

2016年2月1日 · The aim of this study is to give an overview of current knowledge regarding abdominal aortic aneurysm (AAA) growth after endovascular aortic aneurysm repair (EVAR) that could potentially lead to aortic rupture.

To better understand the predictors of AAA sac enlargement after EVAR, we conducted a study using data from a large, multicenter cohort CT scan database to determine the degree of compliance with anatomic guidelines in the instructions for use (IFU) for the EVAR device, examine changes in compliance with the IFU over the last decade, and determi...

2022年10月1日 · The aim of the present study was to analyze the influence of abdominal aortic aneurysm sac shrinkage on the long-term outcomes after endovascular aneurysm repair (EVAR) between patients with favorable and hostile neck anatomy.

2023年9月1日 · Preprocedural image analysis and intraprocedural techniques to fully treat infrarenal abdominal aortic aneurysm sacs outside of the endograft with shape memory polymer (SMP) devices during endovascular aneurysm repair were developed. Prospective, multicenter, single-arm studies were performed.
