To retrospectively analyze patients with intraventricular neurocysticercosis (NCC) who underwent a ventriculoscopic approach at a single neurosurgical center and assess the efficacy of this treatment in patients with intraventricular NCC. ⋯ The ventriculoscopic approach to NCC resection is an effective technique with unique advantages for intraventricular NCC. Radical resection is necessary for intraventricular NCC. Combined application of rigid and flexible endoscopes can improve the total removal rate of intraventricular NCC.

Opinions vary regarding optimal treatment of unstable hangman's fractures, including rigid orthosis and internal fixation. The anatomy of upper cervical spine is complex. The advent of intraoperative 3-dimensional navigation systems facilitates safe and accurate instrumentation. ⋯ Intraoperative O-arm-based navigation is a safe, accurate, and effective tool for screw placement in patients with unstable hangman fracture and achieves good anatomical reduction.

Case Reports
Takotsubo cardiomyopathy triggered by venous air embolism during craniotomy in sitting position: a case report.
We present a case of stress-induced cardiomyopathy (Takotsubo cardiomyopathy) caused by a venous air embolism during a craniotomy performed in the sitting position. ⋯ Intensivists and anesthesiologists in the operating room and in intensive care units need to be aware of stress-induced cardiomyopathy as a probably underdiagnosed disease entity, especially as management differs significantly from other forms of cardiogenic shock. Diagnosis can be accomplished quickly by bedside echocardiography, emphasizing the need for availability of this tool and the integration of stress-induced cardiomyopathy in diagnostic algorithms in the intensive care unit.

Comparative Study
Clinical investigation of refractory chronic subdural hematoma: a comparison of clinical factors between single and repeated recurrences.
Chronic subdural hematoma (CSDH) is sometimes refractory, and this is troublesome for neurosurgeons. Although many studies have reported risk factors or treatments in efforts to prevent recurrence, those have focused on single recurrence, and few cumulative data are available to analyze refractory CSDH. ⋯ When patients with risk factors for refractory CSDH experience recurrence, alternative surgical procedures may be considered as the second surgery, because burr-hole irrigation with closed-system drainage did not reduce refractory CSDH in our study.

Subcallosal artery (ScA) infarction is a well-recognized but uncommon complication of surgical treatment of anterior communicating artery aneurysms. ⋯ Our case demonstrates a rare case of isolated ScA infarction induced by a local vasospasm and highlights the importance of its recognition. An early identification and intervention could potentially halt irreparable cerebral injury.
