Transposition of Superior Cerebellar Artery for Microvascular Decompression in Trigeminal Neuralgia Using an In Situ Superior Petrosal Vein Sling Technique

摘要

BACKGROUND: Several microvascular decompression technical variations for the treatment of medically refractory trigeminal neuralgia have been proposed that can be categorized generally as interposition and transposition techniques. These latter approaches, so-called slinging techniques, have been increasing in popularity, because they can possibly reduce the long-term recurrence rates by preventing the formation of fibrosis and granulomas at the decompression site. We have reported a technique for transposition of the superior cerebellar artery for microvascular decompression in trigeminal neuralgia using the superior petrosal vein as an in situ sling to anchor and reroute the artery away from the nerve.
