BACKGROUND AND PURPOSE The safety and efficacy of WEB flow disruption have been analyzed in small, retrospective series. The object of this study was to evaluate the safety and efficacy of WEB flow disruption in a large, multicenter, prospectively collected population. MATERIALS AND METHODS Data from all patients treated with the WEB-DL device between(More)
The use of flow diverters (FDs) has shown promising results, particularly in the treatment of large or complex intracranial aneurysms. However, some complications can occur both during and after FD treatment, including delayed ipsilateral parenchymal hemorrhage (DIPH). The clinical presentation, etiopathogeny, and management of this complication are not(More)
BACKGROUND AND PURPOSE Follow-up of intracranial aneurysms treated by flow diverter with MRI is complicated by imaging artifacts produced by these devices. This study compares the diagnostic accuracy of three-dimensional time-of-flight MR angiography (3D-TOF-MRA) and contrast-enhanced MRA (CE-MRA) at 3 T for the evaluation of aneurysm occlusion and parent(More)
Early recanalization of occluded vessels in patients with acute ischemic stroke (AIS) by either intravenous thrombolysis (IVT) or endovascular revascularization has been shown to be associated with improved clinical outcomes and reduced mortality. Since the initial report regarding endovascular treatment (EVT) of AIS in 1983, endovascular techniques have(More)
PURPOSE To evaluate the feasibility, safety and efficacy of endovascular treatment with flow diverters in patients with recanalized and multitreated aneurysms in a retrospective, multicenter, single-arm study. METHODS The study included 29 patients with 29 recanalized aneurysms who were treated by flow diverters (Silk or Pipeline devices). Pre- and(More)
Disease in the abdomen and pelvis is frequent in patients with metastatic melanoma (MM). Multidetector row computed tomography is the imaging modality of choice for diagnosis and follow-up of MM. However, positron emission tomographic scan may be used as well as other newer imaging modalities, particularly for imaging of the abdominal and pelvic metastases.(More)
Le trichobézoard, pathologie rare, est défini par la présence d’un corps étranger gastrique formé par des cheveux ou des fibres textiles. Il survient habituellement chez des adolescents présentant des troubles psychiques. La Symptomatologie est variée, le diagnostic, souvent suspecté par la radiologie est endoscopique et le traitement a souvent recours à la(More)
PURPOSE Aneurysm recanalization is a main concern after endovascular treatment of intracranial aneurysms. But to date, no systematic analysis of the risk factors affecting its occurrence has been conducted in a large series of patients. Analysis of Recanalization after Endovascular Treatment of intracranial Aneurysm (ARETA) is a multicenter, prospective(More)
OBJECTIVE To investigate the ability of T2* and fluid-attenuated inversion recovery (FLAIR) MR sequences to detect hemosiderin deposition 3 months after aneurysmal subarachnoid hemorrhage (SAH) in comparison with early non-enhanced CT (NECT) as a gold standard. MATERIALS AND METHODS From September 2008 through May 2013, patients with aneurysmal SAH were(More)
