Ventriculoperitoneal (VP) shunting is a well-established therapy for hydrocephalus. However, complications are frequent. The incidence of idiopathic normal pressure hydrocephalus (NPH) increases with the aging of the population. We evaluated the functional status of patients and the classification of complications associated with VP shunt procedures in our center. ⋯ Although shunt surgery has a high general rate of complications, this rate is significantly lower for patients with NPH. The decision for shunting in patients with NPH should consider the low complication rate specific for the group of patients with NPH.

Enterprise deployment through a PulseRider to treat an anterior communicating artery aneurysm recurrence.
PulseRider (Pulsar Vascular, Los Gatos, California, USA) is a new endovascular device designed to treat wide-neck bifurcation intracranial aneurysms. Deployment of a stent through a PulseRider to treat an aneurysm's recurrence has never been described before. ⋯ An Enterprise stent can be safely opened through a PulseRider in order to treat aneurysm recurrence.

Surgical removal of giant vestibular schwannomas with severe petrous bone involvement remains challenging due to the high risk of complications. The retrosigmoid intradural suprameatal-inframeatal approach (RISIA) allows for safe exposure extending from Meckel's cave to the petrous internal carotid artery (ICA). ⋯ The RISIA allows for safe and effective surgical access during complete tumor resection, even when severe involvement of Meckel's cave and the petrous ICA are observed. The present report is the first to demonstrate the usefulness of this approach in patients with recurrent giant vestibular schwannoma.

Atlantoaxial spondyloptosis (AAS), which is defined as complete displacement of facets of atlas anterior to the facets of axis such that there is no contact between the 2 articulating surfaces, is an extremely rare manifestation of atlantoaxial instability. The reason for an extreme rarity of traumatic AAS is probably the severity of injury in traumatic AAS that is usually incompatible to life. It represents the most severe form of atlantoaxial dislocation, and complete reduction in such a case presents a real technical challenge because of the interlocking of C1-C2 facets. Cranial traction fails to achieve reduction in such cases. ⋯ This case report aims to present the ability of "joint manipulation" and "joint remodeling" techniques in achieving excellent reduction in even one of the most difficult post-traumatic deformities that affect the craniovertebral junction.

The transoral approach provides the most direct exposure to extradural lesions of the ventral craniovertebral junction. The morbidity and mortality from this approach greatly limits its use because they are still feared and debated. Using univariable and multivariable logistic regression analyses, this study aims to identify the factors associated with short-term complications in patients undergoing the transoral approach. ⋯ To reduce complications, it is essential to be aware of and to manage these preoperative risk factors. In such manner, we insinuate that postoperative complications depend on the surgeon's familiarity with the transoral approach.
