摘要目的：探究单纯静脉压迫导致三叉神经痛（Trigeminal neuralgia,TN）患者经微血管减压术（Microvascular decompression，MVD）治疗术后的手术效果。方法：回顾性分析2014年1月至2015年1月于我科经MVD治疗的TN患者，研究其预后及影响预后相关因素。结果：120例TN患者，其中单纯静脉压迫三叉神经患者13例，单纯动脉压迫60例，混合性压迫46例。单纯静脉压迫患者术后1天、3月、1年、3年的缓解率分别为84.6%、76.9%、69.2%、61.5%。单纯动脉压迫患者为88.3%、85.0%、83.3%、70.0%。混合型压迫患者为93.5%、93.5%、91.3%、87.0%。结论：单纯静脉压迫TN患者MVD术后缓解率较单纯动脉压迫TN患者及混合性压迫TN患者低，与混合性压迫TN患者长期缓解率有统计学差异，且混合性压迫TN患者长期缓解率最高。

英文摘要:

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.
