Active clinical trials for "Aneurysm"

Cumulative radiation dose, cost, contrast induced nephrotoxicity and increased demand for computed tomography aortography (CTA) suggest that duplex ultrasonoraphy (DU) may be an alternative to CTA-based surveillance. The investigators compared CTA with DU during endovascular aneurysm repair (EVAR) follow-up. Patients undergoing EVAR have radiological follow-up data entered in a prospectively multicenter database. The gold standard test for endoleak detection was CTA. DU interpretation was performed independently of CTA and vice versa.

The aim of the investigator is to implement 4D FLOW MRI technique into a clinical setting and evaluate the blood flow pattern and wall sheer stress in patients with aortic and/or aortic valve diseases.

The ARCHYTAS Registry is a long-term, global, multicenter, non-randomized, prospective, registry designed to collect "on-label" data in real world clinical settings on patients undergoing endovascular repair with the latest generation Aorfix™ AAA Flexible Stent Graft System. Registry data will augment existing data from ongoing and prospective Aorfix™ clinical trials for the purposes of publication, general product development and quality measures.

The purpose of this study is to determine the prevalence of abdominal aortic aneurysm (AAA) and abdominal aortic atheromatosis (AA-At) using a hand-held ultrasound by a general practitioner in Primary Health Care.

To evaluate the clinical benefits and risks of hybrid operating techniques in management of intracranial aneurysms with coexistence of atherosclerotic intracranial arterial stenosis.

The aim of this study is to prospectively compare the perioperative mortality severe morbidity and the costs of endovascular versus conventional surgical repair of type 1, 2 and 3 thoracal abdominal aortic aneurysms.

The Bifurcated PowerLink System is intended to provide a permanent alternative conduit for blood flow within a patient's abdominal vascular system, which excludes the aneurysmal sac from blood flow and pressure.

The aim of this study is to evaluate a new way to create CT-like images during intra-operative procedures. We want to prove that the quality and information received from DynaCT is satisfactory in implementing stent-graft in abdominal aortic aneurysm.

The investigators expect that the using of prothesis with sinuses has more benefits for long term competence and condition of aortic valve than the using of straight prothesis.

The purpose of this study is to determine if the application of a negative pressure dressing intraoperatively (Prevena; KCI, Inc) to vascular groin incisions decreases the wound complication rate in high risk patients.
