ABSTRACT Objective: To explore the surgical results of patients with Trigeminal neuralgia(TN) treated with microvascular decompression (MVD) due to simple venous compression. Methods: A retrospective analysis of patients with TN treated with MVD in our department from January 2014 to January 2015 was conducted, to investigate the prognosis and prognostic factors. Results: There were 120 patients with TN, including 13 patients with simple venous compression, 60 patients with simple arterial compression, and 46 patients with mixed compression. The remission rates of patients with simple venous compression at 1 day, 3 months, 1 year, and 3 years after surgery were 84.6%, 76.9%, 69.2%, and 61.5%, respectively, and those with simple arterial compression were 88.3%, 85.0%, 83.3% and 70.0%, the patients with mixed compression were 93.5%, 93.5%, 91.3% and 87.0%. Conclusions: The remission rate of MVD in patients with simple venous compression was lower than that in patients with arterial compression and mixed compression, and the long-term remission rate was significantly different from that in patients with mixed compression. |
