OBJECTIVE We report the application of n-butyl-2-cyanoacrylate (n-BCA) in microvascular decompression (MVD) surgery for a Jehovah's Witness patient. To our best knowledge, this is the first case wherein n-BCA has been employed as an adhesive to the offending artery. CASE PRESENTATION A 55-year-old female Jehovah's Witness patient was suffering from serious right hemifacial spasm. Although MVD surgery was needed, the patient resisted any curative medical treatment involving the application of whole blood products, including fibrin glue. Thus, we proposed several choices using artificial materials, including n-BCA as an adhesive, and received informed consent from the patient. RESULT MVD was performed on the dolichoectatic right vertebral artery and right posterior inferior cerebellar artery. The abnormal vessel response disappeared during the procedure and transposition using n-BCA of the concerned vessels was successful. The patient experienced a favorable postoperative clinical course and has been free from the spasm for a year. No abnormal findings were detected in the radiological examination during the follow-up period. CONCLUSION Although careful follow-up is mandatory, n-BCA is a possible alternative option in MVD surgery.
