To observe the hemodynamic changes of the superficial temporal artery (STA) by color Doppler and the correlation between the results of angiography and the hemodynamic changes of the STA after superficial temporal artery-middle cerebral artery (STA-MCA) bypass surgery for moyamoya disease. ⋯ Higher blood flow can develop in anastomosed STA after STA-MCA bypass surgery. The hemodynamic changes of STA after surgery mainly occurred at an early period after operation with little change at 3-month follow-up examination. The increase of blood flow in STA may be due to the low resistance of the intracranial vascular bed. Postoperative Doppler examination of the STA may predict angiographic results of the anastomosis in the early postoperative period. Continuous observation is necessary to identify an accurate correlation between quantitative alteration of the Doppler parameters and angiographic results.

Case Reports Randomized Controlled Trial Comparative Study
Endoscopic surgery for intraventricular hemorrhage (IVH) caused by thalamic hemorrhage: comparisons of endoscopic surgery and external ventricular drainage (EVD) surgery.
Intraventricular hemorrhage (IVH) caused by thalamic hemorrhage has high mortality and morbidity. The aim of this study was to investigate the efficacy and the results of endoscopic surgery for the evacuation of IVH caused by thalamic hemorrhage compared with that of external ventricular drainage (EVD) surgery. ⋯ Endoscopic surgery was found to have significantly lower shunt-dependent hydrocephalus, and the ICU stay was shorter compared with EVD surgery. This can decrease the need for permanent VP shunts in patients with IVH caused by thalamic hemorrhage.

Preoperative determinants of surgical risk in elderly patients with meningioma are not fully defined. This study was undertaken to determine whether the Charlson comorbidity index could be used to accurately predict postoperative outcomes among older patients with meningiomas undergoing neurosurgical resection and thereby make a selection for surgery easier. ⋯ The safe surgical resection of intracranial meningiomas among older patients is possible through the ninth decade of life. The Charlson comorbidity score has been shown to be a strong, consistent predictor of inpatient outcomes.
