A solution to meningiomas at the trigone of the lateral ventricle using a contralateral transfalcine approach.
Access to the trigone of the lateral ventricle is challenging because of the deep location and the intimate relationships to eloquent areas. ⋯ The feasibilities and advantages of this novel approach are discussed.

The prevalent method of ventriculostomy placement is via freehand insertion to cannulate the ventricle at a 90° angle to the skull to get ideal placement. Our goal was to test the validity of this practice in patients without midline shift and with normal ventricular size. ⋯ Our study concludes that not all catheters passed through Kocher's point using a perpendicular trajectory will end up in the ipsilateral frontal horn, and almost 10% of these catheters will be in a nonventricular space. In the instance in which a freehand pass fails to cannulate a ventricle, the safest alternative would be to make only minor adjustments to the perpendicular angle.

To examine the influence of cerebral vasospasm on health-related quality of life after subarachnoid hemorrhage. An additional objective was to determine how the timing of nimodipine therapy can influence health-related quality of life. ⋯ Cerebral vasospasm had little influence on health-related quality of life in our patient population. Health-related quality of life cannot be used as the only argument in favor of treating cerebral vasospasm with nimodipine.

Fluorescence-guided surgery for cranial meningioma has been reported to be useful. There are no reports about spinal cases using this technique. We report on a meningioma of the cervical spine for which fluorescence-guided surgery was used. ⋯ Fluorescence-guided microsurgery is helpful in achieving a total resection of spinal meningiomas, and might therefore reduce the risk of recurrence.
