To describe the operative methods and to investigate the efficacy of ventral neural decompression under microscopic vision with oblique lumbar interbody fusion (OLIF). ⋯ Microscopic ventral neural decompression with OLIF could achieve satisfactory clinical results with minimal complications in selected patients with extruded or sequestered disk.

To explore related factors that influence time to recurrence and prognosis of gliomas. ⋯ This comprehensive analysis revealed that initial World Health Organization grade and Ki-67 proliferative index were independent prognostic factors that predict the time to recurrence of glioma in patients after first surgery.

Variable Moyamoya disease (MMD) genotypes and phenotypes between different races have been suggested previously. This study investigates differences in surgical complications and response to revascularization among Asian patients with MMD compared with other ethnicities in North America. ⋯ Asian patients with MMD may be more susceptible to surgical complications and may differ from other races in their response to revascularization. Further long-term prospective studies are needed to investigate these findings.

Clinical utility of endovascular adjunct for tumor resection is well established, but its role in acute subarachnoid hemorrhage secondary to neoplastic pseudoaneurysm rupture has not been reported. ⋯ A combined targeted endovascular embolization with microsurgical resection to spare the calcarine artery was used to avoid disruption to the optic radiation fiber pathway.

Acquired pial arteriovenous fistula (pAVF) is an extremely rare intracranial vascular malformation, with few case reports in the English literature. This study presents a thorough review and analysis of all acquired pAVF cases from the literature in addition to an illustrated case. ⋯ Acquired pAVF is highly correlated with sentinel neurosurgical procedures or venous occlusion events. These lesions should be regarded as a different disease entity from primary pAVF because of the relatively low-flow shunting and benign clinical course.
