BACKGROUND AND PURPOSE The purpose of our study was to evaluate the technical feasibility, morbidity and mortality, and durability of occlusion of unruptured aneurysms treated with Guglielmi detachable coils (GDCs) with a long-term follow-up. MATERIALS AND METHODS Between January 1998 and January 2005, we treated 321 unruptured aneurysms with GDCs in 5(More)
We review seven patients with intracranial dural arteriovenous fistulae (ICDAVF), each altering the initial type of venous drainage to one with a higher grading during long-term follow-up. Five were discovered due to symptoms of intracranial hypertension, two due to changes in tinnitus and one case following subarachnoid haemorrhage. In five cases, cortical(More)
BACKGROUND Since the pioneering studies of human thalamic anatomy based on histology and binding techniques, little new work has been done to bring this knowledge into clinical practice. OBJECTIVE With the advent of magnetic resonance imaging (MRI) we hypothesized that it was possible, in vitro, to make use of high spontaneous MRI contrasts between white(More)
BACKGROUND AND PURPOSE The management of wide-necked aneurysms or aneurysms with a neck-to-body ratio close to 1 is a difficult challenge for the interventional radiologist because of the risk of coil migration or coil protrusion into the parent vessel. Our objective was to evaluate the efficacy and safety of balloon-assisted coiling as well as the(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 The long-term durability of Guglielmi detachable coil (GDC) embolization of cerebral aneurysms is still unknown. The purpose of this study was to evaluate the stability of anatomic occlusion of aneurysms treated with GDCs and assess the rate of recanalization and re-treatment. METHODS A multicenter study involving 650 patients with(More)
In this article, we briefly review the concept of brain mapping in stereotactic surgery taking into account recent advances in stereotactic imaging. The gold standard continues to rely on probabilistic and indirect targeting, relative to a stereotactic reference, i.e., mostly the anterior (AC) and the posterior (PC) commissures. The theoretical position of(More)
BACKGROUND AND PURPOSE The endovascular treatment (EVT) of cerebral aneurysms has experienced a revolution since 1991 with the introduction of platinum coil technology. During the past 10 years, there has been significant study of the feasibility of this technique, and clinical results of EVT have been published. The long-term durability of Guglielmi(More)
