Simultaneous microvascular decompression for trigeminal neuralgia and hemifacial spasm involving a dolichoectatic vertebral artery in an elderly patient: illustrative case

Neelan J. Marianayagam, Hanya M. Qureshi, Sagar Vasandani, Shaurey Vetsa, Muhammad Jalal, Kun Wu, and Jennifer Moliterno

Trigeminal neuralgia (TN) and hemifacial spasm (HFS) refractory to medical management can commonly be the result of direct contact by an aberrant vessel compressing the root entry zone (REZ) of the trigeminal and facial nerves, respectively. Microvascular decompression (MVD) has been shown to provide lasting relief. 1 In TN, the offending vessel is usually the superior cerebellar artery, whereas in HFS, it is usually the anterior inferior cerebellar artery. There are instances, however, in which an enlarged or dolichoectatic vertebral artery (DVA) can be the

Middle meningeal artery pseudoaneurysm and pterygoid plexus fistula following percutaneous radiofrequency rhizotomy: illustrative case

Rahim Ismail, Derrek Schartz, Timothy Hoang, and Alexander Kessler

The percutaneous approach to the trigeminal nerve via the foramen ovale originated in the early 20th century from Taptas and Hartel in 1911 and 1913, 1 respectively, with electrocoagulation developed by Rethi in 1913. 2 Over the subsequent century, much advancement in the percutaneous techniques has occurred including chemodenervation, radiofrequency ablation, cryoablation, nerve blocks, Botox injections, nerve stimulation, and balloon decompression. 2 Percutaneous treatment for trigeminal neuralgia is generally considered a well-tolerated procedure, with
