Active clinical trials for "Aortic Aneurysm"

Abdominal aortic aneurysms (AAA) are balloon-like swellings of the body's main blood vessel (aorta) as it courses through the abdomen. As a result of the National Aneurysm Screening programme many more of these will be detected. Small AAAs grow slowly and remain a benign condition until the diameter exceeds 2-3 times the diameter of the normal aorta (about 5.5cm in size), when operative repair of the aneurysm is recommended avoiding the potentially fatal event of bursting and bleeding (aneurysm rupture). It is therefore important to identify a strategy to prevent aneurysm growth. There is a suggestion that the use of a specific drug class, angiotensin converting enzyme (ACE) inhibitors, may reduce the risk of rupture of the larger aneurysms. This trial will assess whether an ACE inhibitor (perindopril) has aneurysm-related benefits, in patients with small AAAs at screening centres in the London area. The effects of perindopril versus a placebo(dummy) on AAA growth rates will be compared. In addition by comparing the effects of perindopril with the effects of equivalent blood pressure lowering with another non-ACE inhibitor class of drug (amlodipine) on aneurysm growth rate, we can see whether any benefits of perindopril are simply the result of lowering blood pressure. 225 Patients will be assigned to one of these 3 treatments by chance (randomisation).In addition to analysis of the effect of perindopril and blood pressure lowering,the effect of the treatments on quality of life will be assessed. Patients will return at 3-monthly intervals for an ultrasound scan and blood pressure measurements, with questionnaires regarding quality of life at the start and end of the 2-year research period. An ultrasound scan is a painless test that uses sound waves to create images of organs and structures inside your body.

The purpose of this study is to evaluate the safety and effectiveness of the Talent Endoluminal Spring Graft System, an investigational device, to treat abdominal aortic aneurysms (AAA). The treatment population will include patients with an abdominal aortic aneurysm who meet the inclusion/exclusion criteria. All patients in the treatment population will undergo post-procedure follow-up evaluations at one (1), six (6), and 12 months and annually thereafter up to five (5) years post-procedure.

The primary objective of this trial is to determine whether the Talent Thoracic Stent Graft, an investigational device, is a safe and effective method of treating thoracic aortic aneurysms (abnormal ballooning of the vessel wall) and other thoracic lesions (dissections, transections, pseudoaneurysms, penetrating ulcers, etc.). The endovascular method is a substitute for the major operation that is performed to treat the lesions.

The Zenith(R) Fenestrated AAA Endovascular Graft Clinical Study is a clinical investigation approved by the US FDA to study the safety and effectiveness of the Zenith(R) Fenestrated AAA Endovascular Graft in the treatment of abdominal aortic and aorto-iliac aneurysms.

The objective of this clinical study is to assess the safety and effectiveness of the Cordis Endovascular Quantum LP™ Stent Graft System.

The 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.

The 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

The 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?

Authors hypothesize that aortic root reimplantation procedure is superior over standard aortic valve reimplantation procedure in the incidence of aortic valve replacement.
