Active clinical trials for "Aneurysm"

Seizures are a potential complication of surgical repair of intracranial aneurysms. In order to prevent seizures, many surgeons administer prophylactic anti-epileptic medication during the intra-operative and post-operative period, however, such practice is not supported by clinical data. Retrospective review found the incidence of postoperative seizures was higher in those who received anti-epileptics versus those who did not. The goal is to examine the utility of levetiracetam (Keppra) for seizure prophylaxis in patients undergoing surgical repair of unruptured intracranial aneurysms.

The purpose of this study is to compare endovascular repair using any FDA approved Medtronic AAA Stent Graft System versus surveillance in subjects with smaller abdominal aortic aneurysms (AAA)(4-5CM), with respect to AAA rupture and AAA related deaths.

Male subjects, 65 years of age, living in Oslo, Norway will be invited to be screened for abdominal aortic aneurysm.

This is a prospective study designed to determine the safety and value of Hypoxyprobe-1 (pimonidazole hydrochloride (-HCl)) to detect levels of tissue hypoxia in patients presenting with ascending aortic aneurysm.

This study will assess the initial feasibility of the GORE® EXCLUDER® Thoracoabdominal Branch Endoprosthesis (TAMBE Device) in the treatment of Aortic Aneurysms Involving the Visceral Branch Vessels.

The purpose of the study is to investigate if briefly stopping blood flow to the patient's leg will lead to the patient's body being better able to tolerate possible decreased blood flow to regions of the brain which otherwise frequently happens after subarachnoid hemorrhage. Previous studies show that various organs such as the heart, brain or kidney can tolerate longer periods of decreased blood flow if prior to that insult shorter periods of decreased blood flow were experienced.

Pre-market, single-arm, prospective, open-label, multi-center clinical trial aimed at assessing the safety and the performance of the Medyria TrackCath system in patients undergoing endovascular intervention.

This device was designed to assist in the stent-assisted coil embolization of intracranial aneurysms, specifically those that have a wide neck that would not otherwise maintain the coil embolization material within the aneurysm because of the wide opening at the base of the aneurysm. This device was designed to treat aneurysms that are: unruptured, wide-necked, intracranial, saccular aneurysms arising from a parent vessel ≥ 2 mm and ≤ 4.5 mm. Wide-necked was defined as having a neck > 4mm or dome-to-neck ratio < 2.

This study is designed to evaluate the safety of the PulseRider in patients undergoing treatment for bifurcation basilar or carotid terminus aneurysms.

The Valiant Mona LSA thoracic stent graft system is for the endovascular repair of aneurysms of the descending thoracic aorta (DTA) in patients who require coverage of the left subclavian artery (LSA).The study is intended to assess safety and performance of the device acutely and at 30 days.
