Active clinical trials for "Aneurysm"

The Zenith® Low Profile AAA Endovascular Graft Clinical Study is a clinical trial to study the safety and effectiveness of the Zenith® Low Profile AAA Endovascular Graft used in conjunction with the Zenith® Spiral-Z® AAA Iliac Leg Graft to treat abdominal aortic, aortoiliac, and iliac aneurysms.

The purpose of the Valiant Evo International Clinical Trial is to demonstrate the safety and effectiveness of the Valiant Evo Thoracic Stent Graft System in subjects with a descending thoracic aortic aneurysm (DTAA) who are candidates for endovascular repair.

The purpose of this clinical study is to evaluate the safety and device performance of the Nellix® EndoVascular Aneurysm Sealing System (Nellix System) for the treatment of infrarenal abdominal aortic aneurysms.

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).

The 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.

The purpose of this study is to evaluate the safety and effectiveness of the MicroVention Flow Redirection Intraluminal Device (FRED) system when used in the treatment of wide-necked intracranial aneurysms.

The study will assess the effectiveness, safety and clinical outcomes of the Thoraflex™ Hybrid Device in the treatment of aortic disease affecting the aortic arch and the descending thoracic aorta, with or without involvement of ascending aorta. The study will also assess safety and early clinical outcomes in patients who receive an extension procedure within 1 year of Thoraflex™ Hybrid Device implantation. Lastly the study will assess the safety and clinical outcomes of patients who receive a Thoraflex™ Hybrid Device for treatment of a ruptured aorta. Patients will be followed for 3 years. The Primary Endpoint will be freedom from defined Major Adverse Events (MAE) occurring ≤ 1 year post-procedure.

This clinical research study is designed to determine safety and effectiveness of the Surpass Flow Diverter (Surpass System), an investigational device developed to treat wide-neck, large or giant intracranial aneurysms. An intracranial aneurysm is a bulge in the wall of a blood vessel in the brain. The bulge is caused by a weakening of the vessel wall. If left untreated, the bulge may continue to grow larger and ultimately the vessel may break open (rupture), resulting in serious bleeding into or around the brain. The information collected from this study will be used to evaluate how well patients do when treated with the Surpass System both immediately after treatment of an aneurysm and over a long period of time (5 years).

Endovascular treatment with platinum coils is safe and effective in preventing rebleeding of intracranial aneurysms. Unfortunately, endovascular treatment of aneurysms with coils has been associated with incomplete occlusion at initial treatment (remnant) or at follow-up (recurrence). This in some studies has been as high as 20%. While many such aneurysm remnants or recurrences exhibit benign behavior, many require retreatment to prevent future hemorrhage. A recent randomized controlled trial of aneurysm coiling revealed that aneurysms between 2 and 9.9 mm diameter were more likely to have an improved angiographic and composite clinical outcome when treated with hydrogel-coated coils, an improvement inferred to result from higher packing density afforded by hydrogel expansion(1). The use of hydrogel coils is associated with technical difficulties related to expansion and limited time for deployment. The investigators theorize that similar results could be achieved by using more voluminous bare platinum coils, leading to improved packing density compared to smaller caliber coils, and thus result in lower incidence of remnants or residuals. The relationship between packing densities and composite clinical endpoints having never been shown in a robust fashion, the investigators therefore propose a randomized clinical trial opposing coiling with soft 15-caliber coils to 10-caliber bare platinum coils in aneurysms varying in size from 3 to 9.9 mm. To test the hypothesis that 15-caliber coiling systems are superior to standard 10-caliber coils in achieving better composite outcomes, the investigators propose the DELTA trial: Does Embolization with Larger coils lead to better Treatment of Aneurysms trial, a randomized controlled blinded trial with 2 subgroups of 282 patients each, 564 total: Subgroup 1: Coiled with a maximum proportion of 15-caliber coils as conditions allow Subgroup 2: Coiled with 10-caliber coils.

This study will test the hypothesis that GSK1278863 will reduce neurologic, renal, and/or cardiac ischemia in patients undergoing elective descending thoracic aorta/thoracoabdominal aortic aneurysm (DTA/TAAA) repair, a population known to be at high risk for ischemic events from their underlying pathology and the surgical complexity required to address their disease. Approximately 160 subjects will be stratified according to intervention type (surgical or endovascular repair, with the latter limited to 50% of the total study population) and randomized in a 1:1 fashion to treatment with GSK1278863 (300 milligrams [loading dose] followed by 100 milligrams [mg]/day x 4 days) or placebo starting prior to planned repair, through postoperative day 3. The duration of participation in this study is expected to be approximately 4 to 8 weeks from screening to follow-up.
