Valsalva's Maneuver to Assist Delivery of a Neurocysticercosis Cyst from the Fourth Ventricle

摘要

Valsalva's Maneuver (VM) may be employed in patients undergoing intracranial surgery to confirm venous hemostasis and facilitate tumor resection during transsphenoi-dal pituitary surgery. We used this technique to help deliver a neurocysticercosis cyst from the fourth ventricle of the brain in a 15-yr-old boy. Under general endotracheal anesthesia, the fourth ventricle was opened.
