Removing the posterior longitudinal ligament in cervical corpectomy is a controversial issue. It is unclear whether the risks are counterbalanced by clinical benefits. Another unexplored topic is whether the width of the corpectomy affects outcome. ⋯ Removing the posterior longitudinal ligament in cervical corpectomy may produce a better outcome, particularly when associated with more posterior bone wall removal in the corpectomy.

Comparative Study Observational Study
Association Between Neurological Outcomes Related to Aneurysmal Subarachnoid Hemorrhage and Onsite Access to Neurointerventional Radiology.
An onsite access to neurointerventional radiology (NIR) may be useful for managing patients with aneurysmal subarachnoid hemorrhage (aSAH) after the aneurysm-securing procedure. We aimed to assess the association between neurological outcomes related to aSAH and onsite access to NIR service. ⋯ Australian New Zealand Clinical Trials Registry ACTRN12616000201471.

Subdural hematoma, without any radiographic evidence of subarachnoid hemorrhage, is a rare presentation of a ruptured intracranial aneurysm. Even more rare is the occurrence of a pure subdural hematoma caused by a ruptured cortical saccular aneurysm. We report the eighth case of pure subdural hematoma secondary to a ruptured nonmycotic cortical berry aneurysm. ⋯ In the context of a presentation of spontaneous subdural hematoma, intracerebral aneurysm rupture should be considered as a possible etiology. Prompt vascular imaging with careful evaluation of the entire cerebral vasculature, including the cortical vessels, should be considered.

Transnasal endoscopic approaches to the clivus have been established recently. Comparative analyses with classic lateral approaches are limited. In this study, we compared transnasal endoscopic and lateral approaches to the clivus, quantifying the exposure and working volume of each approach in the anatomy laboratory. ⋯ This quantitative anatomic study shows that endoscopic transnasal approaches to the clivus provide a larger working volume and wider exposure of the clivus compared with lateral approaches.

Although most surgeons are using endoscopy as an adjunct to microscopy in microvascular decompression, a full endoscopic technique is less commonly performed. The present study is aimed to evaluate results of 230 patients of endoscopic vascular decompression. ⋯ Endoscopic vascular decompression is a safe and efficient alternative technique to endoscopic assisted microvascular decompression provided surgeon is experienced in endoscopic surgery. It is helpful in identification of all offending vessels including the double vessel, and anterior compression without brain and nerve retraction.
