Multicenter Study
A multi-institutional, 5-year analysis of initial and multiple ventricular shunt revisions in children.
To evaluate risk factors and predictors of cerebrospinal ventricular shunt revisions in children. ⋯ Higher hospital volume of initial shunt placement was associated with lower revision rates. Substantial hospital variation in the rates of ventricular shunt revision exists among children's hospitals. Future prospective studies are needed to examine the reasons for the variability in shunt revision rates among hospitals, including differences in specific processes of care.

Statin use was not associated with less vasospasm or improved outcome after subarachnoid hemorrhage.
The development of delayed ischemia caused by cerebral vasospasm remains a common cause of morbidity and mortality after aneurysmal subarachnoid hemorrhage. Preliminary studies suggest that 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) may decrease the risk of vasospasm, but additional study is required. ⋯ The addition of statins to standard care was not associated with any reduction in the development of vasospasm or improvement in outcomes after aneurysmal subarachnoid hemorrhage. If there is a benefit to statin use, it may be smaller than suggested by previous studies. However, further randomized controlled trials are awaited.

Device-related infection is a common complication of deep brain stimulator (DBS) implantation. We reviewed the incidence and management of early hardware-related infections in a large series. ⋯ In a large series of new DBS hardware implantations, the incidence of postoperative hardware-related infection requiring further surgery was 4.5%. When only one device component was involved, partial hardware removal was often successful.

Balloon compression of the rootlets behind the trigeminal ganglion for the treatment of trigeminal neuralgia has become an increasingly popular method among neurosurgeons. However, the method has recognized complications, including double vision. Although occurring infrequently, diplopia may cause the patient significant disability. To minimize the risk for this complication, we analyzed our patients with respect to the surgical technique. ⋯ By meticulous surgical technique with close attention to the anatomic position and the shape of the inflated balloon, most cases of postcompression diplopia should be avoided.

Endoscopic third ventriculostomy is a well-known surgical option in the treatment of noncommunicating hydrocephalus. We studied complications and long-term success in 202 patients to demonstrate the safety and efficacy of laser-assisted endoscopic third ventriculostomy (LA-ETV) using a unique "black" fiber tip/diode laser combination for controlled tissue ablation. ⋯ This study demonstrates that LA-ETV is a safe and effective procedure that is comparable to other techniques for ETV. LA-ETV is most effective in patients aged 1 year and older and in patients with aqueductal stenosis and tumors, with a low major complication rate.
