PURPOSE To review the symptoms and progression of dural arteriovenous fistulas (AVFs) and correlate the findings with various angiographic patterns. MATERIALS AND METHODS Patterns of venous drainage allowed classification of dural AVFs into five types: type I, located in the main sinus, with antegrade flow; type II, in the main sinus, with reflux into the(More)
BACKGROUND AND PURPOSE The goal of this study was to characterize cortical reorganization after stroke and its relation with the site of the stroke-induced lesion and degree of motor recovery using functional MRI (fMRI). METHODS Fourteen stroke patients with an affected upper limb were studied longitudinally. Three fMRI sessions were performed over a(More)
PURPOSE To evaluate the accuracy of hippocampal and amygdala volume measurements in diagnosing patients in the early stages of Alzheimer disease. METHODS Measurements of the hippocampal formation, amygdala, amygdalohippocampal complex (the two measurements summed), caudate nucleus, and ventricles, normalized for total intracranial volume, were obtained on(More)
The authors report the CT and MR findings of a rare benign primary choroid plexus papilloma developed in the CPA with invasion of the neighboring structures, apparently the first description of such a case. Differential diagnosis with other CPA tumors is discussed. Papillomas should be considered among the vascular, calcified enhancing masses of the CPA(More)
PURPOSE To compare three-dimensional (3D) time-of-flight magnetic resonance (MR) angiography with digital subtraction angiography (DSA) in the follow-up of intracranial aneurysms treated with selective endovascular placement of detachable coils. MATERIALS AND METHODS Sixty-eight consecutive patients with intracranial aneurysms were included in the(More)
BACKGROUND AND PURPOSE Polyglycolic/polylactic acid-covered platinum coils have been proposed to reduce the rate of aneurysm recanalization after endovascular treatment. A prospective and multicenter registry was conducted in France to evaluate the safety and short-term and midterm efficacy of Matrix coils. This analysis focused on anatomic midterm results.(More)
The development of new devices, especially controlled detachable coils, has made the endovascular approach one of the modalities for the treatment of intracranial aneurysms. We describe the treatment and present the results of 35 patients treated by selective occlusion of basilar artery aneurysms in our department during a period of 2 years (November(More)
BACKGROUND AND PURPOSE The management of unruptured intracranial aneurysms remains controversial and the results of endovascular treatment are not precisely known because no prospective data exist. The first prospective multicenter study (ATENA) was conducted in Canada and France to determine clinical outcome and risks of this treatment. METHODS Six(More)
BACKGROUND AND PURPOSE FD stent placement is a promising therapy for challenging intracranial aneurysms. Long-term evaluations about angiographic and morphologic results are still missing. This is the aim of this multicenter series. MATERIALS AND METHODS We report our experience and 1-year FU in a retrospective chart review of 65 consecutive subjects with(More)
BACKGROUND AND PURPOSE Flow disruption with the WEB-DL device has been used safely for the treatment of wide-neck bifurcation aneurysms. The stability of aneurysm occlusion after this treatment was evaluated in the short and midterm, but not in the long term. This retrospective multicenter European study is the continuation of an already published series(More)
