Although delayed postoperative clip slippage has been reported in previous case reports and case series, its true incidence with high rate of follow-up imaging has not been reported. We attempted to determine the incidence of clip slippage in a cohort of consecutive aneurysm clippings. ⋯ Because our series showed a 2.6% incidence of clip slippage, clipped aneurysms should be monitored with early and delayed vascular follow-up imaging. Lower cumulative clip closing force, single clip placement, and oversized clip blade length may be risk factors for postoperative aneurysmal clip slippage.

The emergence of C8 radiculopathy is a known complication following cervicothoracic osteotomies. However, the clinical profile of C8 radiculopathy is not well understood. The aim of this study was to investigate the rate of C8 radiculopathy after cervicothoracic osteotomies and to form a clinical profile describing the characteristics through a systematic review of the literature. ⋯ Of the 451 patients included in this study, 53 had C8 radiculopathy (11.8% of the total patient population). Moreover, the rate of C8 radiculopathy decreased over time in a statistically significant manner. An understanding of the factors associated with the incidence of C8 radiculopathy is essential for future improvement of patient outcomes.

In this article, we aimed to describe some of the currently most challenging problems in neurosurgical management of hydrocephalus and how these can be reasons for inspiration for and development of research. We chose 4 areas of focus: 2 dedicated to improvement of current treatments (shunt implant surgery and endoscopic hydrocephalus surgery) and 2 dedicated to emerging future treatment principles (molecular mechanisms of cerebrospinal fluid secretion and hydrocephalus genetics).

This study aims to present the clinical characteristics and surgical treatment in patients with intracranial hemangioblastomas and to investigate risk factors for postoperative functional outcomes. ⋯ Generally, patients can benefit from surgical removal of intracranial hemangioblastomas with favorable functional outcomes. Body mass index, number of resected tumors per operation, and intraoperative blood loss can be used as risk factors for immediate functional outcomes after surgery, and preoperative hydrocephalus for long-term functional status.

Occipital interhemispheric transtentorial approach for a pineal region meningioma with pseudobulbar palsy.
Meningiomas represent 8%-10% of all pineal region (PR) tumors. When they arise from the falx, tentorium, or tentorial incisura, they are not always considered a true PR tumor, as they do not originate from it but instead only grow toward the region. The true meningioma of PR must be originated from the arachnoid envelope of the pineal gland or from the 2 leaflets of the velum interpositum. ⋯ Careful management of the deep veins is mandatory during the resection of PR meningiomas. The venous system improvement after the surgery may be associated with the dramatic recovery seen in this unique case. The patient consented to publication of her images.
