The safety and efficacy of flow diversion (FD) in the treatment of cerebral aneurysms have been reported by many studies. FD has enabled the treatment of complex aneurysms and aneurysms that were previously untreatable by conventional means. It has achieved high rates of obliteration with essentially no recanalization, and its indications have continued to expand, now including ruptured aneurysms, blister aneurysms, and dissecting aneurysms. ⋯ In summary, FD shows promise to be an effective treatment for ruptured, blister, and dissecting aneurysms.

There is inadequate neurosurgical literature discussing appropriate clinical study design. Here, we explore considerations for 2 fundamental study designs of epidemiology: experimental and observational cohort studies, through examples of theoretical yet realistic neurosurgical research questions. By examining 2 common neurosurgical procedures-namely, subdural drains for evacuation of chronic subdural hematoma, and the utility of navigation for placing external ventricular drains-we characterize the framework of cohort study models for clinical research applications.

The Colloid Cyst Risk Score (CCRS) was developed to identify symptomatic patients and stratify risk of hydrocephalus among patients with colloid cysts. Its components consider patient age, cyst diameter, presence/absence of headache, fluid-attenuated inversion recovery (FLAIR) hyperintensity, and location within the third ventricle. ⋯ The CCRS has good inter- and intrarater reliability when tested in an independent sample of patients, though strength of agreement varies among individual criteria. The validity of the CCRS requires independent evaluation.

The bulk of a resident's daily work is patient care related; however, other aspects of residency training are vital both to a resident's education and to the advancement of the field. Basic science and clinical research are the more common academic activities in which residents participate after completion of daily patient care objectives. Less frequently, residents participate in a process vital to the delivery of efficient, cost-effective, and safe patient care: hospital policy development. ⋯ The inclusion of residents in policy development has improved the process for declaring brain death and management of patients with devastating neurological pathology. Resident involvement in hospital policy initiatives can be successful, valuable to the institution, and beneficial to patient care. Resident involvement is predicated on faculty and institutional support of such endeavors.
