Multicenter Study Clinical Trial
Long-Term Clinical and Angiographic Outcomes Following Pipeline Embolization Device Treatment of Complex Internal Carotid Artery Aneurysms: Five-Year Results of the Pipeline for Uncoilable or Failed Aneurysms Trial.
Early and mid-term safety and efficacy of aneurysm treatment with the Pipeline Embolization Device (PED) has been well demonstrated in prior studies. ⋯ Our 5-yr findings demonstrate that PED is a safe and effective treatment for large and giant wide-necked aneurysms of the intracranial ICA, with high rates of complete occlusion and low rates of delayed adverse events.

From Russian Refugee to Iowa's First Neurosurgeon and Pioneer of Cranial Hemostasis: The Legacy of Anatole Kolodny (1892-1948).
After immigrating to the United States from Russia in the wake of the First World War, Anatole Kolodny became the first surgeon in Iowa to specialize in neurological surgery. Kolodny was vital to the initial practice of neurosurgery in the state of Iowa and to the specific development of academic neurosurgery at the University of Iowa. In an effort to improve his surgical outcomes, Kolodny invented a hemostat that bears his name and is still used for cranial hemostasis. ⋯ Kolodny's achievements brought favorable attention to the university and altered the course of neurosurgery at the University of Iowa. Of significant importance, Kolodny influenced and trained Iowa's second neurosurgeon, Olan Hyndman, and this action led the way to the eventual recruitment of the university's first division head of neurosurgery. The purpose of this manuscript is to shed light on Kolodny's important contributions to the development of neurosurgery not only at Iowa, but also in the profession as a whole.

The role of stereotactic radiosurgery (SRS) for recurrent glioblastoma and the radionecrosis risk in this setting remain unclear. ⋯ Gamma Knife may benefit a subset of focally recurrent patients, particularly those who are younger with smaller recurrences. Higher prescriptions are associated with improved post-SRS survival and do not seem to have greater risk of symptomatic treatment effect.

Reports on the natural history of tumor growth and hearing in patients with a vestibular schwannoma (VS) are almost exclusively short-term data. Long-term data are needed for comparison with results of surgery and radiotherapy. ⋯ Tumor growth occurred in only a minority of patients diagnosed with an intracanalicular VS during 10 years of observation. The risk of hearing loss is small in patients with normal discrimination at diagnosis. Serviceable hearing is preserved spontaneously in 34% according to AAO-HNS and in 58% according to the word recognition score.
