Filter by:Study purpose: This study will investigate anatomical factors associated with increased risk of major adverse aorta-related event and accelerated growth of abdominal aneurysm based on 3-dimensional analysis of CT images. Study design: a multicenter single-arm prospective observational study. Subject: patients with small abdominal aortic aneurysm with maximal diameter of 30-50 mm (n=323) Methods: Patients diagnosed with small AAA based on CT will be enrolled after considering inclusion and exclusion criteria and prospectively followed clinically and with CT at 1 year. Primary endpoint: Major adverse aorta-related events (death, aortic rupture, or aneurysm growth >0.4 cm per year) at 1 year Secondary endpoints: 1) clinical events : death, aortic rupture, aneurysm growth >0.4 cm per year, surgical or endovascular repair 2) Changes in CT parameters of aneurysm: diameter, volume, wall shear stress
This study will evaluate a randomized comparison of direct versus snare techniques for cannulation of contralateral gate during an endovascular aneurysm repair (EVAR) procedure. This information will be used to determine if primary snaring is superior to retrograde cannulation in decreasing procedural time and radiation exposure.
The study aims at screening Israeli Arab men, smokers or past smokers, for abdominal aortic aneurysms (AAA). The screening is to be performed at the family doctors clinics in the rural arab erea of the north of Israel. Goals: The investigators aim at revealing the actual prevalence of AAA in the Israeli Arab smoking men population. By revealing this prevalence we believe the need for a nation-wide screening program for AAA will turn available for assessment. In addition, the goal of improving the accessibility of health services for the Israeli Arab population is a key issue in the design of the research. 2000 patients are to be enrolled in the study over a period of 2 years. Each of the patients will be examined once for a duplex ultra-sound and will be classified into one of 4 sub-groups according to the maximal aortic diameter found.
This post-market study is approved by the US FDA to evaluate the long-term safety and performance of the Zenith® Fenestrated AAA Endovascular Graft.
The objective of this study is to assess the safety and effectiveness of the Endologix Nellix® System for the endovascular repair of infrarenal abdominal aortic aneurysms (AAA).
As endovascular procedures become more complex, there is a growing need for 3D image overlay to assist with device guidance and placement. Currently, a 3D image is typically created intra-operatively using 3D rotational angiography (3D-RA) or cone-beam CT (XperCT). This 3D image may then be overlaid on live fluoroscopy to provide 3D guidance information (Dynamic 3D Roadmapping). Philips Healthcare multimodality overlay products allows registration of a pre-acquired MR/CT or 3D rotational image to live fluoroscopy.
