The objective of this study was to evaluate the cortical thickness and the volume of deep gray matter structures, measured from 3D T1-weighted gradient echo imaging, and white matter integrity, by diffusion tensor imaging (DTI) in patients with typical absence epilepsy (AE). ⋯ Abnormalities found in white matter integrity may help to better understand the pathophysiology of AE and optimize diagnosis and treatment strategies.

The study aimed to compare efficacy and safety of aspiration thrombectomy (AT) to stentriever thrombectomy (SRT) in patients with basilar artery (BA) occlusion (BAO). ⋯ In primarily embolic BAO, aspiration thrombectomy was faster, effective and not detrimental to outcome as compared to stentriever thrombectomy. Thus, it may be justified to use aspiration thrombectomy as first-line treatment in these patients.

The purpose of this study is to assess the functional connectivity of the motor cortical network in patients with brachial plexus avulsion injury (BPAI) after contralateral C7 nerve transfer, using resting-state functional magnetic resonance imaging (RS-fMRI). ⋯ The resting-state inter-hemispheric functional connectivity of the bilateral M1 areas is altered in patients after contralateral C7 nerve transfer, suggesting a functional reorganization of cerebral cortex.

Idiopathic intracranial hypertension (IIH) is a disorder of increased intracranial pressure in the absence of any known causative factor. Sinus stenosis is common in these patients. Stenting of stenotic dural sinuses has gained popularity as a treatment option, since these stenoses may contribute to an obstruction of the venous return, and, thereby may contribute to IIH via an increase in venous sinus pressure. We evaluated the safety and efficacy of endovascular treatment in IIH with venous sinus stenosis. ⋯ Venous sinus stenting is a safe and effective alternative to other invasive treatments (e.g., optic nerve sheath fenestration, CSF diversion) in patients with IIH. The majority of patients have a persistent clinical benefit.
