Comparison of Beta-blocker Versus Angiotensin Receptor Blocker for Suppression of Aneurysm Expansion...
Small Abdominal Aortic AneurysmVarious medical therapies have been proposed to prevent abdominal aortic aneurysm expansion. However, there have been very few randomized clinical trials to support use of any of these treatments. Several animal studies and observational reports suggest that ARBs can be useful in reducing abdominal aortic aneurysm (AAA) growth. However, so far, ARBs have not been evaluated in a randomized clinical trial. Therefore, the purpose of the study is to evaluate the effect of valsartan, an ARB, on annual growth rate in comparison with atenolol, a beta-blocker. Our hypothesis is that valsartan is superior to atenolol in the suppression of the aneurysm growth at 12 months. The BASE trial is designed as a investigator-initiated, multi-center, randomized controlled open-label trial. Patients with small AAA (aorta diameter <5cm) will be randomized 1:1 either to valsartan or to atenolol group. Randomization will be stratified by the AAA size (max. diameter >4 cm or ≤4 cm). Patients will receive either valsartan (daily dose 80 mg or more) or atenolol (daily dose 50 mg or more) for 12 months. A CT scan will measure the maximal diameter of AAA at baseline and 12 months. The annual growth of AAA will be compared between the valsartan and the atenolol group.

Safety and Effectiveness Study of Endovascular Abdominal Aortic Aneurysm Repair Using the Nellix®...
Abdominal Aortic Aneurysm (AAA)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).

Non-Invasive Treatment of Abdominal Aortic Aneurysm Clinical Trial
AneurysmThe primary aim of this study is to determine if doxycycline (100 mg bid) will inhibit (by at least 40%) the increase in greatest transverse diameter of small abdominal aortic aneurysms (3.5-5.0 cm in men, 3.5-4.5 cm in women) over a 24-month period of observation in comparison to a placebo-treated control group.

Evaluation of the Endovascular Repair for Aortic Aneurysm (EVAR) Program at LHSC
Abdominal Aortic AneurysmThe purpose of this study is to compare the cost effectiveness, quality of life and outcomes of the endovascular stent graft repair with the open surgical repair of abdominal aortic aneurysms.

Endoleak Repair Guided by Navigation Technology
Aortic AneurysmEndoleakThe study is aimed at investigating whether repair of endoleak type II can be improved by adding navigation technology. Can this technology increase precision by guiding the needle that punctures through the skin as used during the repair procedure? Can the procedure logistics be improved by using navigation technology instead of computed tomography (CT) guidance of the needle puncture? Parameters logged during the procedure: was the needle placement successful? number of needle punctures? time used on guidance procedure X-ray exposure dose

Endurant for Challenging Anatomy: Global Experience Registry
Abdominal Aortic Aneurysms With Challenging AnatomyThe Department of Vascular Surgery at Catharina Hospital Eindhoven, The Netherlands initiates the Endurant for Challenging Anatomy: Global Experience (EAGLE) Registry. The aim of this study is to collect clinical information on the performance of the Endurant Stent Graft System for endovascular repair in anatomically challenging aneurysms, and to critically assess whether the current guidelines for anatomic eligibility to endovascular treatment with this system are still applicable. This study aims at creating a database that can be pooled/ compared with the ENGAGE database. This study aims at answering two major questions: Is the technical success rate of successful delivery and deployment of the Endurant (II) similar in anatomically challenging aneurysm? Is the successful treatment rate comparable in anatomically challenging aneurysms, or does treatment of these aneurysms lead to more complications and reinterventions?
