The ventriculoscopic approach has been considered to be more safe and effective in the treatment of hydrocephalus, arachnoid cysts and intraventricular lesions in neurosurgery. We found that intraoperative bleeding-related complications have the greatest impact on ventriculoscopic surgery. Until now, few studies fully discussed this complication. ⋯ Intraoperative hemorrhage in ventriculoscopic surgery should be paid more attention. Generally, a skilled neurosurgeon can address hemorrhage with a low complication rate. Consequently, the ventriculoscopic approach is safe and effective in the treatment of specified brain ventricular disease.

Pineal apoplexy (either hemorrhagic or ischemic) may complicate the course of a tumor at this site. This event usually is characterized by an acute clinical onset and requires emergency surgical management whereas the regression of the lesion is a much rarer outcome. ⋯ Vanishing tumors of the pineal region may occur in different circumstances, resulting from absence of any medical and surgical action to minor manipulation of the tumor to obtain a biopsy. This variety may reflect different underlying mechanisms, leading to hemorrhagic or ischemic change of the tumor and its subsequent regression, although radiological imaging may fail to document hemorrhage or ischemia.

In reverse bypass that used a naturally formed "bonnet" superficial temporal artery, intraoperative volume flow measurement quantifies flow augmentation after revascularization, confirms flow preservation, and identifies inadvertent vessel compromise. ⋯ Modification of the intraoperative stroke risk and prediction of the long-term patency after reverse bypass can be achieved by meticulous intraoperative blood flow evaluation.

Despite advances in skull base surgery, achieving effective surgical management of jugular foramen schwannomas (JFSs) that avoids postoperative cranial nerve (CN) deficits remains a challenge. Subtotal resection followed by radiosurgery (rather than radical resection) is increasingly being viewed as a better treatment strategy. Here, an institutional database was retrospectively analyzed for outcomes after surgical treatment of JFSs to evaluate the optimal strategy for managing JFSs. ⋯ Our results suggest that conservative resection of JFSs via a familiar intracranial approach plus radiosurgery may be an effective surgical alternative for improving functional outcome with adequate oncologic control.

Comparative Study
The difficulties and risks of Y-stent-assisted coiling: a comparison of first and second stenting procedures.
Y-stent-assisted coiling (YSAC) requires multiple device accesses for double stenting. The purpose of this study was to test the hypothesis that second stenting procedures are riskier than first stenting procedures. ⋯ In YSAC, second stenting procedures seem riskier than first stenting procedures, particularly when SDs occur. A proper device or delivery method may reduce the risks.
