Precisely defining complications, which are used to measure overall quality, is necessary for critical review of delivery of care and quality improvement in endovascular neurosurgery, which lacks common definitions for complications. Furthermore, in endovascular interventions, events that may be labeled complications may not always negatively affect outcome. Our objective is to provide precise definitions for quality evaluation within endovascular neurosurgery. Thus, we propose an endovascular-specific classification system of complications based on our own patient series. ⋯ We propose an endovascular-specific classification system of complications with 4 categories: mechanical, technical, judgment errors, and critical events. This system provides a framework for future studies and quality control in endovascular neurosurgery.

Currently, anterior, posterior, or combined approaches are used in various spinal disorders; however, a single-stage posterolateral transpedicular approach with 360° stabilization and vertebrectomy provides better results for spinal tumors. ⋯ In spinal tumors, 360° fusion performed via a posterolateral approach is a less risky, relatively safe, and less invasive method. This method, which reduces the risks of anesthesia and internal problems and decreases cost, is an essential technique for decreasing hospitalization duration, improving pain levels, and achieving faster mobilization and faster initiation of radiotherapy and chemotherapy.

Pituitary apoplexy is a rare complication of the initial administration of leuprolide acetate. ⋯ Clinicians should be aware of this rare but known complication of leuprolide injection so that prompt diagnosis and treatment initiation are performed in patients with leuprolide-associated pituitary apoplexy.

Large schwannomas with intradural and extradural extensions are often challenging surgical lesions. A variety of approaches, usually requiring large exposures, removal of facets and pars interarticularis, and spinal stabilization, have been described. The aim of this study is to describe the "dual approach," a less invasive technique for the excision of these lesions. ⋯ The dual approach is a novel and unique technique that allows complete and safe removal of large intradural and extradural dumbbell tumors through a less invasive approach and no need for instrumentation.

The expanded endoscopic endonasal ("far medial") approach to the inferior clivus provides a unique surgical corridor to the ventral surface of the pontomedullary and cervicomedullary junctions. However, exposing neoplasms involving the jugular foramen (JF) through this approach requires extensive nasopharyngeal resection and lateral dissection beyond the boundaries of the endonasal corridor, limiting the extent of resection and restricting to use of this approach to expert surgeons. Here we describe a multiportal endoscopic transoral and endonasal approach to maximize surgical access to the JF and clivus. ⋯ This approach provides access to the JF from a ventromedial trajectory, enabling panoramic views, and outlines an expanded surgical exposure (superolateral intradural and inferolateral extracranial). It may provide optimal access for resection of dumbbell-shaped lesions of the JF.
