This article, published in the Journal of Neurological Surgery, describes a case study of a 29-year-old male with a giant, calcified, partially thrombosed vertebrobasilar aneurysm that was causing brainstem compression. The patient underwent endovascular embolization of the aneurysm's mural channel for distal control, followed by a far lateral craniectomy and laminectomy for exposure and transection of the bilateral vertebral arteries. The thrombosed portion of the aneurysm was then resected using an ultrasonic aspirator to relieve brainstem compression. The authors of the article are Vincent N.
