Active clinical trials for "Aneurysm"

This post market registry consists of a retrospective and a prospective part. The first part is a retrospective registry of all implanted IBE devices of Gore in the Netherlands after CE mark was obtained, to get an initial insight on the feasibility and safety of this procedure. The second part is to prospectively register all data on implanted IBE Gore devices, in order to gain more robust data on the efficacy of the device in maintaining hypogastric artery patency.

The aim of this project is to demonstrate the benefit of the use of aortic iliac branch endoprosthesis in the iliac aneurysms and to avoid the classic complications.

The purpose of this study is to answer the following question: Leads a primary coagulation corrected with a single dose of fibrinogen concentrate after ascending aorta-arc reconstruction to a decrease in the number of allogenic blood transfusions, compared to placebo?

This is an observational cohort study addressing the incidence of cerebral microemboli and alterations of cerebral hemodynamic physiology of the Relay®Branch thoracic stent-graft system.

The purpose of this study is to assess the extent of thrombosis in the Zenith Alpha Spiral-Z® stent graft.

Aortic disease refers to the blood in the aortic lumen entering the aortic mediastinum from the tear of the aortic intima, separating the mediastinum and extending along the long axis of the aorta to form the true and false separation state of the aortic wall. This disease is rare, and the incidence rate is 100 thousand to 200 thousand a year, with the peak age of 50-70 years old. 65%-70% patients died in the acute stage due to cardiac congestion and arrhythmia, so early diagnosis and treatment is very necessary. The aim of this study is analyze clinical outcome of Chinese patients with acute aortic syndrome and aortic aneurysm.

The overall objective of the POP-STAR project is individualized surveillance for patients diagnosed with abdominal aortic aneurysms by means of more precise, patient-specific AAA growth prediction.

The management of patients with unruptured aneurysms is controversial. Patients with unruptured aneurysms may suffer intracranial hemorrhage, but the incidence of this event is still debated. Endovascular treatment can prevent rupture, but involves immediate risks; furthermore, successful treatment does not eliminate all risks. A randomized trial may be the best way to demonstrate the potential benefits of endovascular over conservative management of unruptured aneurysms.

Objective of the present study is to compare endovascular repair versus surveillance and, eventually delay treatment in patients with small abdominal aortic aneurysms (AAA), with respect to patient survival, AAA rupture and AAA related death risks.

Background: Aortic stent-graft is useful to occlude intimal tear and prevent further dilatation of the false lumen in patients with aortic dissection. The long-term benefit of aortic stent-graft in patients with uncomplicated distal aortic dissection has not been well demonstrated, especially in patients at high risk of aneurysmal change and death. Purpose: The purpose of the study is to evaluate long-term clinical benefit of stent-graft insertion performed just after the acute phase into the descending thoracic aorta in patients with distal aortic dissection and at high risk of aneurysmal change of the dissected aorta.
