Abstract

The trigeminocerebellar artery (TCA) originates from the basilar artery and perfuses the trigeminal nerve root and cerebellar hemisphere. In this case report, we identified a TCA compressing the trigeminal nerve in a 65-year-old woman with left trigeminal neuralgia (TN). We discuss the surgical approach to achieve excellent results. A 65-year-old woman was referred to our department due to experiencing paroxysmal electric pain in the left mandibular area, which was triggered by eating. She was initially treated medically by a family doctor, although the effectiveness of the treatment decreased over time. The patient was diagnosed with TN and underwent left microvascular decompression surgery. During the surgical procedure, it was observed that the left superior cerebellar artery (SCA) was in contact with the trigeminal nerve from the cranial side and that the TCA formed a loop that severely compressed the trigeminal nerve and ran between the sensory and motor branches. The SCA was moved to the cerebellar tentorial side and fixed, and the TCA was dissected from the trigeminal nerve, pulled out, and repositioned such that the loop would not press on the nerve. Following the surgery, the patient’s left TN disappeared immediately, and she was discharged from the hospital one week later without any neurological deficits. In conclusion, to avoid complications, it is essential to manage the vessels that penetrate the trigeminal nerve with care. One effective and safe surgical procedure involves decompressing the trigeminal nerve by removing the responsible artery and altering its trajectory.
