To study the operative method, special technique and curative effect of complete neuroendoscopic microvascular decompression(MVD) related to vertebrobasilar artery compression. Thirteen patients with functional cranial nerve disease caused by vertebrobasilar artery as direct or indirect responsible vessel accepted complete endoscopic MVD, including 11 patients with hemifacial spasm and 2 patients with trigeminal neuralgia. The procedure and curative effect of endoscopic surgery were analyzed retrospectively. All procedures of complete neuroendoscopic MVD were successfully completed.Intraoperative observation by endoscope showed that 6 cases were oppressed directly by vertebral artery, 2 cases were oppressed directly by basilar artery, 5 cases were combined oppressed by displaced basilar artery and other vessels (1 case was superior cerebellar artery and 4 cases were anterior inferior cerebellar artery). During the operation, Teflon sheets was placed directly into the compression point in 2 cases, the "Pre-placed" technique was used to place Teflon sheets in 7 cases, and the "Set up bridge" technique was used to place Teflon sheets in 4 cases. Follow-up for 8-38 months,the symptoms disappeared completely in 12 cases and improved in 1 case. No deaths and severe complications occurred, such as postoperative bleeding, cerebellar infarction and intracranial infection. MVD related to vertebrobasilar artery compression can be performed by complete neuroendoscopic technique, which can achieve sufficient decompression effect and curative effect.Flexible use of the special technology of placing Teflon sheets by single-hand under endoscope, such as the "Pre-placed" and "Set up bridge" technique, is an important technical guarantee for the successful completion of endoscopic MVD.
