The Woven Endobridge (WEB) device for treatment of intracranial aneurysms: a systematic review.
The Woven Endobridge (WEB) device is an innovative endovascular device for treatment of intracranial aneurysms, especially bifurcation and wide-neck aneurysms. Although not approved by the U.S. Food and Drug Administration, it has been available in Europe since 2011. The aim of this review is to evaluate the outcomes of WEB device use for intracranial aneurysm treatment. ⋯ Despite initial promising results, the WEB device should be used with caution given its potentially large learning curve and because it has primarily been investigated only in wide-neck and bifurcation aneurysms. In addition, currently available prospective studies have short follow-up, and the device has not been directly compared with other treatment modalities.

Trigeminal neuralgia (TN) is a chronic brain condition involving the trigeminal nerve and characterized by severe and recurrent facial pain. Although the cause of TN has been researched extensively, there is a lack of convergence on the physiologic processes leading to pain symptoms. This review seeks to better elucidate the underlying pathophysiology of TN by analyzing the outcomes of studies that use magnetic resonance structural imaging and diffusion-weighted imaging to examine nerve damage in patients with TN. ⋯ A review of the studies included indicates that neural differences exist between the affected and unaffected sides in patients as well as between patients and controls in both structural and diffusion metrics. The amalgamated data suggest that damage of the trigeminal nerve tissue is commonly found in patients with TN and could be a primary factor in TN pathophysiology.

Cerebellar arteriovenous malformation (C-AVM) is poorly tolerated because of its aggressive natural history. The aim of this study was to delineate long-term outcomes of Gamma Knife stereotactic radiosurgery (GKRS) for C-AVM. ⋯ GKRS is a reasonable intervention for C-AVMs. Symptomatic complications are rare, and the long-term outcomes are favorable.

This study assessed whether video-electroencephalography (VEEG) monitoring followed by surgery was cost-effective in adult patients with drug-resistant focal epilepsy under Thai health care context, as compared with continued medical treatment without VEEG. ⋯ For patients with drug-resistant epilepsy, VEEG monitoring followed by epilepsy surgery was cost-effective in Thailand. Therefore it should be recommended for health insurance coverage.

Observational Study
Time is brain! Analysis of 245 cases with decompressive craniectomy due to subarachnoid hemorrhage.
Decompressive craniectomy (DC) may become a life-saving measure for patients with subarachnoid hemorrhage (SAH). However, the benefit of early DC has not been shown yet. We aimed at identifying the clinical value of DC timing. ⋯ Not the timing of DC indication (primary/secondary), but rather the actual time left between the ictus and DC is crucial for the functional improvement of patients with SAH requiring DC. Especially, individuals without the signs of severe early brain injury strongly benefit from early DC.
