Hypertension and smoking are risk factors for aneurysm formation or rupture. We aimed to identify differences in aneurysm morphologies associated with hypertension or smoking in patients with anterior communicating artery (AcoA) aneurysms. ⋯ Aneurysm size was an independent morphologic parameter associated with smoking in patients with ACoA aneurysms compared with other aneurysm morphologies. Smoking may be associated independently with increased aneurysm size and should be given up in patients with AcoA aneurysms.

Neuroendoscopic Intraventricular Biopsy in Children with Small Ventricles using Frameless Varioguide® System.
Endoscopic biopsy for intraventricular tumors in pediatric patients with small ventricles is a challenging procedure because of the risk of morbidity during the intraventricular approach. We describe the use of the VarioGuide system for intraventricular endoscopic biopsy in 9 consecutive pediatric patients with intraventricular lesions and small ventricular size. All patients had lesions in the anterior part of the third ventricle with a median frontal and occipital horn ratio of 0.33. ⋯ Diagnoses included germinomas in 4 patients, hamartoma in 1 patient, hypothalamic astrocytoma in 2 patients, and craniopharyngioma in 2 patients. The use of the VarioGuide system for intraventricular endoscopic biopsy is highly recommended for pediatric patients with small ventricle size. This technique may help minimize the risk of unnecessary brain damage during the entrance to small ventricles.

Obesity can be associated with increased complications and potentially worse outcomes. We aimed to evaluate the impact of obesity on complications and outcomes in patients with adult spinal deformity (ASD) who underwent minimally invasive surgery (MIS). ⋯ Our results suggest that obesity does not negatively impact complication rate or clinical outcomes in patients with ASD treated via MIS approaches.

Traumatic brain injury is a major general health concern. This study aims to evaluate a possible relationship between the serum level of glucose during admission and the outcome of patients with severe traumatic brain injury. ⋯ Admission serum glucose is not a significant indicator of outcome in patients with severe head trauma.

The Trans-Visible Navigator: a see-through neuronavigation system using augmented reality.
The neuronavigator has become indispensable for brain surgery and works in the manner of point-to-point navigation. Because the positional information is indicated on a personal computer (PC) monitor, surgeons are required to rotate the dimension of the magnetic resonance imaging/computed tomography scans to match the surgical field. In addition, they must frequently alternate their gaze between the surgical field and the PC monitor. ⋯ The main advantage of the present system is that it achieves volumetric navigation in contrast to conventional point-to-point navigation. It extends augmented reality images directly onto real surgical images, thus helping the surgeon to integrate these 2 dimensions intuitively.
