Active clinical trials for "Aneurysm"

The purpose of this study is to evaluate the clinical performance of the Zenith Alpha™ Abdominal Endovascular Graft for the treatment of abdominal aortic or aorto-iliac aneurysm.

The vascular surgery is a highest risk procedure when considering postoperative complications associated with the cardiovascular system. The leading clinical presentation is acute hemodynamic decompensation. However, one of the possible pathomechanisms might be repolarization disturbances. Many of perioperative risk factors of cardiac complications are modifiable. The identification may help in the global perioperative risk reduction. Aim: The aim of the study was an identification of the factors which may release clinically overt repolarization disturbances. Methods: The study group consisted of 100 patients, diagnosed with abdominal subrenal aortic aneurysms or peripheral arterial disease scheduled for an elective "open" vascular surgery procedure. The authors investigated whether age, gender, comorbidities or some perioperative factors (including hemodynamic, metabolic or genetic) were related to the occurrence of clinically concealed repolarization disturbances or clinically disclosed cardiac complications in postoperative time up to 30 day and one year after vascular surgery procedure.

The aim of the study is to assess if venous distension in patients with aneurysmatic arteriopathy is higher compared to patients with peripheral arterial occlusive disease (PAOD) and in controls.

An observational non-randomized, multi-center, prospective assessment of the clinical utility of the WEB Aneurysm Embolization System in subjects with ruptured intracranial aneurysms deemed appropriate for endovascular treatment. The population being treated in this Registry is a subset of the CE marked indication.

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

Flow diverters have been approved since 2012 for the treatment of large, wide neck intracranial aneurysms. These devices have been associated with embolic events which cause blockage in a blood vessel and can result in long term complications. One possible cause of these events is the formation of small emboli during placement of the device.

The RIPAT study is a prospective, randomized, double-blind study organized by the neurovascular group of the Clinical Department of Neurosurgery of Innsbruck Medical University, Innsbruck, Austria. Patients aged 18+ in whom the treatment of an un-ruptured intracranial aneurysm is indicated are eligible for study participation. Prior to aneurysm treatment, with the patient already under general anesthesia, the blood supply to an arm will be restricted for 3x 5minutes by inflating a standard blood pressure cuff. The study hypothesis is that this "remote ischemic preconditioning" maneuver is able to prevent a stroke during the following treatment of the aneurysm.

The Vascutek Anaconda™ Stent Graft System for repair of Abdominal Aortic Aneurysms (AAA) is the subject of this observational study. 180 patients will be implanted with the Anaconda™ Stent Graft System and will be followed-up annually for 5 years post-implant. The study will satisfy the requirements of the French National Authority for Health (Haute Autorité de santé) and the data collected will be used for reimbursement renewal.
