Superselective angiography is the most accurate technique in the analysis of brain arteriovenous malformation (AVM) angioarchitecture. Therefore, we reviewed the selective and superselective angiograms of 100 consecutive patients with intracerebral AVMs. Our purpose was to determine which parameters of angioarchitecture were significantly correlated with a(More)
Brain-stem, middle latency and late auditory evoked potentials (BAEPs, MLAEPs and LAEPs, respectively) were recorded in a patient 2 months after removal of affecting the quadrigeminal plate. Simultaneously, MRI showed a left unilateral lesion involving the inferior colliculus, brachium colliculi and the medial geniculate body (MGB). On dichotic listening,(More)
UNLABELLED Intracranial angioplasty stenting may be an efficient therapy in patients with intracranial atherosclerotic symptomatic vertebrobasilar artery stenosis unresponsive to optimal medical therapy. We present our experience in this setting. RESULTS The study included 12 cases (8 men, 4 women), with an age range of 43-78 years (mean 62.6 years).(More)
BACKGROUND AND PURPOSE Complete intracranial aneurysmal occlusion by endovascular techniques is required for successful treatment and is presumably influenced by several parameters. The purpose of this study was to investigate whether operator experience and angiographic characteristics of intracranial aneurysms correspond to the degree of endovascular(More)
PATIENTS AND TECHNIQUES A series of 67 patients treated for cerebral AVMs with a multidisciplinary approach is reported, with special attention for the complications due to treatment. The malformations were classified after the Spetzler Grading Scale, with 67% low-grade and 33% high-grade AVMs. Three modes of treatment were used: surgical resection,(More)
The size of intracranial aneurysms is the only characteristic shown to correlate with their rupture. However, the critical size for rupture has varied considerably among previous accounts and remains a point of controversy. Our goal was to identify statistically significant clinical and morphological factors predictive of the occurrence of rupture and(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)
A 48 year old woman developed an acute vestibular syndrome associated with upside down vision a few hours after minor cervical trauma. Magnetic resonance imaging showed an ischaemic lesion in the territory of the medial branch of the posterior inferior cerebellar artery. An arteriogram showed a dissection of the left extracranial vertebral artery.
BACKGROUND AND PURPOSE The benefit of recanalization in basilar artery occlusion (BAO) has been established. The baseline extent of brain stem damage may also influence the outcome. We investigated whether a baseline diffusion-weighted imaging (DWI) score may provide additional prognostic value in BAO. MATERIALS AND METHODS We analyzed baseline clinical(More)
