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.

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.

Few studies have assessed the effect of Chiari malformation type 1 (CM-1) surgical decompression on cervical lordosis and range of motion (ROM). We aimed to assess the effect of expansile duraplasty on postoperative cervical mobility and spinal stability. ⋯ Adding an expansile duraplasty to craniovertebral decompression in CM-1 patients with severe tonsillar herniation may restore cervical ROM while preserving stability and alignment. This may relieve postoperative pain and improve clinical prognosis.

Positional compression of the vertebral artery (VA) owing to cervical spondylosis is an uncommon cause of stroke. We report two cases of cervical spondylosis causing wake-up stroke, which is extremely rare. ⋯ Magnetic resonance angiography of extracranial cervical VAs may be useful as an initial screening test for VA compression secondary to cervical spondylosis as a rare cause of wake-up stroke, especially in cases of cerebral infarction in the posterior circulation with no evidences of causative arrhythmia and intracranial lesions.

Case Reports
Bow Hunter's Syndrome from a Tortuous V1 Segment Vertebral Artery Treated with Stent Placement.
Bow hunter's syndrome is a dynamic and reversible occlusion of the vertebral artery occurring after rotation or extension of the neck. The V3 segment is the most common site of compression, especially at the atlantoaxial joint. Surgical decompression with or without cervical fusion has been the mainstay of therapy. Endovascular intervention, such as placement of stents, is rarely performed. ⋯ Stent placement is a safe and effective option for V1 segment causes of Bow Hunter's syndrome, especially in absence of bony compression.
