Active clinical trials for "Aortic Aneurysm"

The purpose of this study is to evaluate the safety and efficacy of custom made devices, Zenith t-Branch devices and physician modification of FDA approved off-the-shelf endovascular grafts in the treatment of patients with complex abdominal aneurysms, aortoiliac aneurysms, thoracoabdominal aneurysms and aortic arch aneurysms who (1) have anatomy not suitable for endovascular repair using grafts currently marketed in the United States,(2) are deemed unsafe to wait the required time necessary for commercial endograft manufacturing, and (3) are at high risk for open surgical repair. Amendment to the study has created a cohort open to people with connective tissue diseases such as Marfan, Ehlers-Danlos or Loey-Dietz syndromes to enroll in the trial. An additional amendment to the study allows the use of a custom made device to treat an aneurysm in the aortic arch.

An investigator-initiated, prospective, consecutively enrolling, non-randomized single institution clinical evaluation of the safety and effectiveness of branched and fenestrated-branched endovascular stent grafts to preserve branch vessels when used in the treatment of patients with thoraco-abdominal aortic aneurysms. The study evaluates non-FDA-approved off the shelf and custom made branched and fenestrated-branched stent grafts manufactured by Cook Medical. The primary objectives of this study are to determine whether fenestrated-branched and branched endovascular grafts are a safe and effective method of treating patients with thoraco-abdominal aortic aneurysms.

This is a single-center study to evaluate the safety and effectiveness of three investigational devices, the Cook Custom Aortic Endograft, the Zenith t-Branch Endovascular Graft, and the Surgeon-Modified Endografts in the treatment of aortic pathologies involving the visceral vessels. The three investigational devices offer an endovascular approach to treat complex aortic pathologies that cannot be treated with commercially available devices. This customized, endovascular approach has the potential to decrease hospital length of stay, pulmonary complications, and in-hospital mortality.

Aortic aneurysms represent the most common and dangerous aortic diseases. Although conventional aortic repair techniques cure the disease, there is a high risk of paraplegia particularly in extensive thoracoabdominal aneurysms due to impaired blood supply to the spinal cord. The PAPA-ARTiS trial will assess the clinical safety and efficacy of the MISACE (Minimally-Invasive Segmental Artery Coil-Embolization) procedure, a novel therapeutic concept to reduce the risk of paraplegia due to aneurysm repair. The study investigates the MISACE procedure as a potential pre-treatment prior to open or endovascular aneurysm repair in patients with thoracoabdominal aortic aneurysms. Patients will be randomized to one of the two treatment strategies: a) aneurysm repair without MISACE pre-treatment, or b) aneurysm repair with MISACE pre-treatment.

The primary objective of the clinical investigation is to assess the use of the Medtronic Valiant Thoracoabdominal Stent Graft System to repair thoracoabdominal aortic aneurysms in patients having appropriate anatomy. The primary intent of the study is to assess safety and preliminary effectiveness of the device. Additionally, the study will assess technical success and treatment success at each follow-up interval.

The primary objective of this single arm, prospective feasibility study, Impact of Frailty on Clinical Outcomes of Patients Treated for Thoracoabdominal and Complex Abdominal Aortic Aneurysms with Physician-Modified Fenestrated and Branched Stent Grafts, is to assess the use of the physician-modified fenestrated/branched endografts to repair thoracoabdominal and complex aortic aneurysms in subjects having appropriate anatomy, at high risks for open repairs. The primary intent of the study is to assess safety and preliminary effectiveness of the device acutely (i.e., treatment success and technical success), at 30 days (i.e., the rate of major adverse events (MAE)) and at 3 months, 6 months, 12 months, and annually to 5 years (i.e., the proportion of treatment group subjects that achieve and maintain treatment success). Additionally, this study will assess the degree of patient frailty before and after the aneurysm repair, as well as the association between the preoperative baseline frailty and clinical outcomes detailed above. This will help improve subject selection in identification of high risk patients who would not only suffer poor clinical outcomes, but also experience decline in their functional status.

Evaluation of the safety and efficacy of a multi-branched thoracoabdominal stent graft system for thoracoabdominal aortic aneurysm.

This is a study to assess the safety and effectiveness of endovascular treatment of thoracoabdominal (TAAA) and paravisceral abdominal (PVAAA) aortic aneurysms. The investigational operation involves placing a stent-graft over the aortic aneurysm.

This is a study to assess the safety and effectiveness of endovascular treatment of aortic aneurysms involving the proximal aortic arch. The investigational operation involves placing a stent-graft over the aortic aneurysm.
