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)
BACKGROUND AND PURPOSE We conducted a retrospective evaluation of the results of endovascular treatment (EVT) of middle cerebral artery aneurysms (MCAAs) in a center where embolization is the first treatment option considered. MATERIALS AND METHODS Ninety-two MCAAs were diagnosed in 87 patients between September 2001 and January 2006. The strategy of(More)
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)
BACKGROUND AND PURPOSE The aim of this study was to determine the feasibility and usefulness of contrast-enhanced MR angiography (CE-MRA) for the follow-up of intracranial aneurysms treated with detachable coils, by comparing CE-MRA with digital subtraction angiography (DSA) and 3D time-of- flight (TOF) MRA. METHODS Thirty-two patients with 42 treated(More)
A 39-year-old woman presented with a right intra-cavernous carotid aneurysm measuring 1.76 cm×1.33 cm. The aneurysm was treated with a self-expandable flow-diverter stent. Follow-up MRI showed normal flow in the internal carotid artery with partial thrombosis of the aneurysmal sac. Two weeks later, the patient developed a right direct carotid-cavernous(More)
A 12-year-old boy with epilepsy and subcortical laminar heterotopia (band heterotopia) underwent a functional MRI protocol to study voluntary motor activity in the hand. Finger tapping produced an activation of a contralateral limited and focused frontal cortical area both in the subcortical band heterotopia and the overlying cortex. Despite its(More)
We reviewed the cranial MRI and radionuclide cisternograms of four adults with postural headache indicating spontaneous intracranial hypotension (SIH). All four underwent clinical and radiological follow-up. MRI showed diffuse, thin meningeal enhancement; bilateral subdural fluid collections; and morphological abnormalities secondary to "sagging" of the(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)
The aim of this study was to evaluate endovascular treatment of anterior communicating artery aneurysms using Guglielmi detachable coils GDC. To obtain long-term follow-up, we selected patients treated between October 1992 and March 1994. Among the 251 berry aneurysms treated by detachable coils at our institution, 36 were located at the anterior(More)
PURPOSE To determine the safety and reliability of a new platinum microcoil (Micrus), in the treatment of intracranial aneurysms. PATIENTS AND METHODS Seventy-eight patients (28 male and 50 female patients; age range, 28-83 years; mean age, 44 years) with 80 intracranial aneurysms were treated in 10 centers in Belgium and France. All aneurysms were(More)
