Review Case Reports
De novo aneurysm associated with superficial temporal artery to middle cerebral artery bypass: report of two cases and review of literature.
De novo aneurysm formation has been reported as a rare complication of superficial temporal artery (STA) to middle cerebral artery (MCA) bypass surgery. ⋯ Persistent hemodynamic stress with hypertension in an artificial T-shaped vasculature and traumatic injury during surgical manipulation are the most important causes for de novo aneurysms after STA-MCA bypass. Follow-up magnetic resonance and computed tomography angiography examinations, along with appropriate blood pressure control, are recommended for patients who have undergone STA-MCA bypass surgery.

China is a densely populated country faced with more than 1 million cases of traumatic brain injury annually. Since the late 1930s, there has been a great improvement in the field of neurosurgery in the treatment of neurotrauma. ⋯ We present a historical vignette of the development of neurotrauma in China over almost 80 years. It is valuable to have this documentation of the growth of neurosurgery in China by authors who are familiar with the subject matter.

Review Meta Analysis
Perioperative complications and long-term outcomes after bypasses in adults with moyamoya disease: a systematic review and meta-analysis.
Surgical revascularization for adults with moyamoya disease (MD) includes direct, indirect, or combination bypasses. It is unclear which provides the best outcomes. We sought to determine the best surgical management for adults with MD by comparing perioperative complications and long-term outcomes among 3 bypass types. ⋯ Overall, our analyses suggest that direct bypass with or without indirect augmentation provides the best outcomes for adults with MD.

Randomized Controlled Trial
Opening the Internal Hematoma Membrane does not Alter the Recurrence Rate of Chronic Subdural Hematomas - A Prospective Randomized Trial.
Factors determining the recurrence of chronic subdural hematomas (CSDHs) are not clear. Whether opening the so-called internal hematoma membrane is useful has not been investigated. ⋯ Opening the internal hematoma membrane does not alter the rate of patients requiring revision surgery and the number of patients showing a marked residual hematoma 6 weeks after evacuation of a CSDH.

Review Case Reports
Intramedullary recurrence of a thoracic meningioma - Presentation of an unusual case and review of the literature.
Spinal meningiomas are typically extra-axial, slow-growing, benign tumors that arise from the arachnoid cap cells. Intramedullary spinal meningiomas are exceedingly rare with few cases reported in the literature. ⋯ Intramedullary spinal meningiomas, particularly intramedullary low-grade recurrence of a previously extramedullary tumor, are rare phenomena. Although the pathogenic mechanisms are not well understood, intramedullary recurrence as described in this patient may reflect extrinsic factors related to prior surgical resections in addition to histologic progression. When operating on recurrent extramedullary lesions, aggressive arachnoid dissection may predispose patients to unusual patterns of recurrence.
