探讨3D-TOF-MRA联合3D-FIESTA在血管压迫性三叉神经痛中的诊断价值研究

Diagnostic Value of 3D-TOF-M RA Combined with 3D-FIESTA in Vascular Compression Trigeminal Neuralgia

目的探讨分析三维时间飞跃法磁共振血管成像(3D-TOF-MRA)联合三维双激发平衡式稳态自由进动序列(3D-FIESTA)在血管压迫性三叉神经痛中的诊断价值。方法回顾性分析本院2017年7月~2019年5月收治的102例血管压迫性三叉神经痛患者的临床资料。于微血管减压术(MVD)术前均予以3D-TOF-MRA、3D-FIESTA及3D-TOF-MRA联合3D-FIESTA检查对责任血管的种类显示情况及评估结果。结果以术中所见结果为金标准,MVD对责任血管阳性检出率为97.06%;联合检查对小脑后下动脉、基底动脉、岩静脉血管阳性检出率与3D-TOF-MRA、3D-FIESTA单独比较无统计学意义(P>0.05);联合检查对小脑上动脉、小脑前下动脉血管阳性检出率更高(P<0.01)。结论两种方法联合诊断血管压迫性三叉神经痛对MVD术前评估具有高准确性和重要的指导意义。

Objective To investigate the diagnostic value of 3D-TOF-MRA combined with 3D-FIESTA in vascular compression trigeminal neuralgia.Methods The clinical data of 102 patients with vascular compression trigeminal neuralgia in our hospital from July 2017 to may 2019 were retrospectively analyzed.3D-TOFMRA,3D-FIESTA and 3D-TOF-MRA combined with 3D-FIESTA were performed before microvascular decompression(MVD)operation to check the type display and evaluation results of responsible vessels.Results The gold standard was intraoperative diagnosis,the positive detection rate of MVD in responsible vessels was 97.06%.There was no significant difference in the positive detection rates of posterior inferior cerebellar artery,basilar artery and petrous vein between combined examination and 3D-TOF-MRA and 3D-FIESTA alone(P>0.05).The positive detection rate of superior cerebellar artery and anterior inferior cerebellar artery by combined examination were higher(P<0.01).Conclusion The combination of two methods for diagnosing vascular compression trigeminal neuralgia has higher accuracy and important guiding significance for preoperative evaluation of MVD.
