Randomized Controlled TrialFactors associated with shunt-dependent hydrocephalus after decompressive craniectomy for traumatic brain injury.
OBJECTIVE Posttraumatic hydrocephalus (PTH) affects 11.9%-36% of patients undergoing decompressive craniectomy (DC) and is an important cause of morbidity after traumatic brain injury (TBI). Early diagnosis and treatment of PTH can prevent further neurological compromise in patients who are recovering from TBI. There is limited data on predictors of shunting for PTH after DC for TBI. ⋯ The median duration from injury to shunt placement was 43.7 days. Multivariate analysis showed that the presence of interhemispheric hygroma (OR 63.6, p = 0.001) and younger age (OR 0.78, p = 0.009) were significantly associated with the need for a shunt after DC. CONCLUSIONS The presence of interhemispheric subdural hygromas and younger age were associated with shunt-dependent hydrocephalus after DC in patients with severe TBI.

Comparative StudyEffects of different surgical modalities on the clinical outcome of patients with moyamoya disease: a prospective cohort study.
OBJECTIVE Bypass surgery is the most common treatment for moyamoya disease (MMD), but there is controversy over which surgical modality is best. The objective of this study was to evaluate the clinical outcome of patients with MMD after undergoing different surgical modalities. METHODS A series of 696 consecutive MMD patients treated between June 2009 and May 2015 were screened in this prospective cohort study. ⋯ No significant difference was observed between the different surgical modalities (p = 0.548). CONCLUSIONS CB and DB are more effective at preventing recurrent ischemic strokes than IB. However, there is no evidence that these 3 surgical modalities demonstrate significant differences in preventing recurrent hemorrhage.

Multicenter StudyClinical outcomes of an endoscopic transclival and transpetrosal approach for primary skull base malignancies involving the clivus.
OBJECTIVE The endoscopic endonasal approach for treating primary skull base malignancies involving the clivus is a formidable task. The authors hypothesized that tumor involvement of nearby critical anatomical structures creates hurdles to endoscopic gross-total resection (GTR). The aim of this study was to retrospectively review the clinical outcomes of patients who underwent an endoscopic endonasal approach to treat primary malignancies involving the clivus and to analyze prognostic factors for GTR. ⋯ In addition, the laterality of the tumor was found to be a statistically significant predictor in multivariate analysis (OR 41.16, 95% CI 1.12-1512.65; p = 0.043). CONCLUSIONS An endoscopic endonasal approach can provide favorable clinical and surgical outcomes. However, the tumor laterality should be considered as a potential obstacle to total removal.

OBJECTIVE Multiple meningiomas account for 1%-10% of meningiomas. This study describes epidemiological aspects of the disease and its management, which is more challenging than for single tumors. METHODS A consecutive series of adult patients with ≥ 2 spatially separated meningiomas was reviewed. ⋯ CONCLUSIONS Multiple meningiomas are often asymptomatic, probably because the majority are small and a significant proportion are induced by radiation. Approximately two-thirds of patients with multiple meningiomas require therapy, but only one-third of all meningiomas need active treatment. The authors recommend surveillance for stable and asymptomatic meningiomas and therapy for those that are symptomatic or growing.
