Complication Caused by Use of Fibrin Glue in Vessel Transposition for Trigeminal Neuralgia -Case Report-

Abstract

A 64-year-old man underwent microvascular decompression of the left superior cerebellar artery (SCA) for left trigeminal neuralgia (TN) using a sling of Teflon tape fixed to the tentorium with fibrin glue. The TN disappeared immediately after surgery, but recurred unusually rapidly at 2 weeks later at the same intensity as before. Second surgery revealed the SCA was suspended from the tentorium, but the trigeminal nerve was stretched and displaced superolaterally because of adhesion to the superior petrosal vein. The adhesion was thought to involve the fibrin glue used during the sling retraction procedure. The nerve was meticulously dissected from the adhesion, and the trigeminal nerve was placed in the correct position. The postoperative course was uneventful, and the TN disappeared completely. We recommend that the smallest amount of the fibrin glue possible be used to avoid adhesion to the surrounding neurovascular elements.
