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.
Eligible subjects in this study will have either a known abdominal aortic aneurysm (AAA) or because they do not have an AAA (control group). The purpose of this research study is to further study, through FEA, changes that occur in the mechanical properties of the aortic wall. The investigator will compare two radiotracers, 18F-FDG and 11C-PBR28 to determine if one provides more useful and reliable information about inflammation. 18F-FDG and 11C-PBR28 are radioactive drugs that will be used for imaging during the PET-CT scan. The investigator will also compare the results describing the mechanical properties of the AAA wall to the degree of inflammation in that wall as determined by PET-CT imaging to define new and better predictors of AAA growth and/or rupture.
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.
Abdominal Aortic Aneurysm (AAA) is a potentially life threatening condition. If the aneurysm ruptures, the mortality can be as high as 80%. Endovascular aneurysms repair (EVAR) is a minimal invasive procedure and has been widely used on treating AAA. Advanced endovascular techniques are used to treat patients with more complex pathology by using custom-made devices and additional stents. In order to accomplish the technical success on advanced EVAR, with the current imaging equipment and technique for EVAR procedures (i.e. live x-ray fluoroscopy and 2-D digital subtraction angiography (DSA)), multiple angiograms on the target arteries (arteriograms) are required. Subsequently patients are exposed to higher dose of contrast and radiation, compared to conventional EVAR. This study is to assess the feasibility of proper visceral and renal arteries catheterization using a 3D model obtained from pre-procedural computed tomographic angiography (CTA), fused with real-time fluoroscopy, without contrast injection or angiographic run-offs thus minimizing the contrast use and patient radiation exposure while achieving procedure success during Advanced EVAR.
The purpose of this clinical trial is to assess and evaluate the safety and efficacy of the Treovance Stent-Graft with Navitel Delivery System in subjects with Abdominal Aortic Aneurysms (AAA).
This study is designed to assess the safety, tolerability and efficacy of ACZ885 on aneurysmal growth rate in subjects with abdominal aortic aneurysms (AAA). The purpose of the study is to provide data to enable decisions regarding the further development of ACZ885 for subjects with abdominal aortic aneurysms. The design of this study addresses the primary objective of evaluating the change in aneurysmal size in subjects with AAA as a result of treatment with ACZ885.
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.
