Aneurysm Clinical Trials

Thoracic aortic dissection (TAD) is a critical clinical condition partly due to the rupture of aortic aneurysm. Mostly, surgical treatment can reduce the symptoms and extend life span of patients with thoracic aortic aneurysm and dissection (TAAD). However, mortality of TAAD remains high because of the huge blood lost from ...

This is a traditional device feasibility study intended to generate preliminary safety and efficacy information that may be used to plan an appropriate future study, or to inform further product development. The study is a prospective, non-randomized, non-blinded, single-arm, single-center study. The purpose of this study is to evaluate clinical ...

The traditional endovascular treatment of aneurysms is based on the utilization of stent-grafts that create a mechanical barrier between the aneurysmal sac and normal blood flow. Problems such as endoleak and occlusion of collateral arteries impede its application in complex aneurysms adjacent to or involving vital branches. Advanced branched/fenestrated endografts ...

Aneurysms and dissection involving the descending aorta and aortic arch have historically been treated with open surgical techniques, requiring cardiopulmonary bypass and deep hypothermic circulatory arrest (DHCA). Despite increasing experience and refinement of these procedures, there remains a substantial rate of morality and morbidity. The goal of Thoracic Endovascular Aortic ...

FEVAR branches can occlude jeopardizing perfusion of the organs they supply. A recent study has shown the rate of patency as 95.7% at 1 year and 88.6% at 4 years. Pooled analysis has shown a 4.5% rate of renal artery occlusion during 12 month follow up with 2.3% going on ...

CAR is a prospective observational study, initiated by the Department of Vascular Surgery at University Medical Centre Utrecht (UMCU), The Netherlands. The study is descriptive in nature. The registry will be conducted according to the principles of the Declaration of Helsinki (64th WMA General Assembly, Fortaleza, Brazil, October 2013). The ...

Overview The management of aneurysmal subarachnoid hemorrhage (aSAH) in Switzerland has not been assessed on a national level to date. The investigators united all comprehensive neurovascular care centres in Switzerland to create a registry for aSAH. This registry helps collect clinical and management data from different centres and pools it ...

RATIONALE Hemoptysis, mild or massive, is worrisome for both patients and physicians. The management is different depending on the causes, which are not well defined for the North American population. Despite the fact that this symptom is commonly reported in clinic, there are only a few studies published on this ...

Intracranial artery disease has been more detected with development of HR-MR. HR-MR can depict vascular wall directly and give us more information beyond the pre-existing imaging modalities such as digital subtraction angiography, magnetic resonance angiography, computed tomography angiography. Hence, HR-MR is considered to become promising imaging modality for intracranial artery ...

Recently a new and novel noninvasive imaging-based technique known as Magnetic Resonance Elastography (MRE) was developed that is capable of quantifying stiffness of soft tissues such as liver, spleen, kidney, heart brain, breast, aorta etc. In MRE a person is laid into an MR scanner which is similar to all ...
