Comparative Study
A Comparison of Ventriculoperitoneal and Ventriculoatrial Shunts in a Population of 544 Consecutive Pediatric Patients.
Although ventriculoperitoneal shunts (VPS) remain the first-line option in most instances of pediatric hydrocephalus, the long-term efficacy of ventriculoatrial shunts (VAS) remains unknown. ⋯ VAS can be a useful alternative to VPS when the abdomen is unsuitable, particularly in older children. Although VPS demonstrates superior overall survival, it should be understood that elective VAS lengthening procedures are often necessary, especially in younger patients. If elective lengthening procedures are not considered true failures, then the devices show similar survival.

Multicenter Study Observational Study
Safety and Effectiveness of the Pipeline Flex Embolization Device With Shield Technology for the Treatment of Intracranial Aneurysms: Midterm Results From a Multicenter Study.
The safety and efficacy of the first generation of the Pipeline Embolization Device (PED; Medtronic Inc) have been proven in large case series. Ischemic events are one of the most common complications following treatment of aneurysms with flow diverters. The new PED Flex with Shield technology (PED Shield; Medtronic Inc) was introduced to minimize the rate of complications. ⋯ The PED Shield is a safe and effective treatment for intracranial aneurysms. The results regarding total occlusion and ischemic complications did not differ from those obtained in case series using previous versions of the PED. Long-term follow-up and comparative studies are required to provide stronger conclusions regarding the reduced thrombogenicity of this device.

Adult spinal deformity (ASD) has gained significant attention over the past decade with improvements in diagnostic tools, classification schemes, and surgical technique. The demographics of the aging population in the United States are undergoing a fundamental shift as medical care advances and life expectancy increases. The "baby boomers" represent the fastest growing demographic in the United States and by 2050, the number of individuals 65 yr and older is projected to reach 89 million, more than double its current size. ⋯ Rates of surgery for ASD and case complexity are both increasing, with concomitant increase in the cost of deformity care. At the same time, patients are more medically complex with increasing number of comorbidities that result in increased surgical risk and complication profiles. This review aims to highlight recent trends in the epidemiology and socioeconomic patterns in surgery for ASD.

Multicenter Study
Flow Diversion for Treatment of Intracranial Aneurysms in Pediatric Patients: Multicenter Case Series.
Though the Pipeline Embolization Device (Medtronic) is approved for use in adults 22 yr and older, the high efficacy and long-term durability of the device is attractive for treatment of intracranial aneurysms in younger patients who often have aneurysms less amenable to traditional endovascular treatments. ⋯ Flow-diversion treatment is a safe and effective treatment for intracranial aneurysms in patients younger than 22 yr. Rates of complete aneurysm occlusion and adverse events are comparable for rates seen in older patients.
