In moyamoya angiopathy, transient neurologic symptoms (TNS) are occasionally observed after superficial temporal artery (STA)-middle cerebral artery direct bypass surgery. The purpose of this study was to investigate the correlation between TNS and postoperative magnetic resonance imaging as well as perform a perfusion study. ⋯ STA dilatation was correlated with TNS after direct bypass surgery for moyamoya angiopathy.

To compare the outcomes between patients older and younger than 65 years who underwent single-level minimally invasive transforaminal interbody fusion (MI-TLIF) surgery. ⋯ MI-TLIF presented similar safeness and acceptable outcomes and complication rate in both groups. Cyst formation may be aggravated by cage subsidence, because cage subsidence was a useful potential predictor of cyst formation.

Arteriovenous malformation surgery is particularly demanding owing to the need to control bleeding of small, deep white matter vessels during and after removal of the nidus; this is probably one of the most critical moments of arteriovenous malformation surgery. The aim of this article is to describe a useful technique based on the use of tweezers to temporarily stop the blood flow followed by coagulation with the thulium laser. ⋯ Results were good with no postoperative complications. Our results could encourage a more standardized use of the described technique.

We sought to characterize patterns and treatment for intracranial meningiomas in the Surveillance, Epidemiology, and End Results set of cancer registries. ⋯ The incidence of intracranial meningiomas increased, while tumor size at the time of diagnosis decreased. Moreover, the number undergoing no treatment increased as a treatment strategy and was more likely employed for older patients, those of African-American race, and those with smaller tumors.

To retrospectively evaluate the midterm therapeutic effect of enlarged encephalo-duro-myo-synangiosis (EDMS) for moyamoya disease (MMD) in young children. ⋯ Enlarged EDMS is safe and effective for MMD in young children. Extensive and multilayered revascularization could significantly preserve neurologic function. The long-term effect on posterior circulation disease development needs further investigation.
