【摘要】：目的探讨椎基底动脉压迫型前庭阵发症的磁共振影像学特征。方法共收集前庭阵发症(vestibular paroxysmia,VP)患者64例,分为非椎基底动脉压迫型组(对照组)32例和椎基底动脉压迫型组(观察组)32例,应用三维时间飞跃法磁共振血管成像技术,判断64例患者的前庭蜗神经周围有无神经血管交互压迫(neurovascular cross-compression,NVCC)及其压迫类型,并对两组间NVCC压迫点至前庭蜗神经出脑干处的最短距离、基底动脉及双侧椎动脉血管直径、双侧椎动脉间血管直径变异度进行统计学分析。结果在观察组NVCC压迫点距前庭蜗神经出脑干处距离为(6.26±2.02)mm明显小于对照组(8.17±1.98)mm(t=-3.872,P=0.000,P0.01);而观察组椎动脉血管直径(3.53±0.42)mm与对照组(3.44±0.31)mm无明显差异(t=0.962,P=0.340,P0.05);两组的基底动脉血管直径观察组(3.74±0.41)mm与对照组(3.65±0.29)mm间亦无统计学意义(t=0.992,P=0.326,P0.05);而观察组的双侧椎动脉血管直径变异度(1.09±0.31)mm明显高于对照组(0.82±0.35)mm(t=3.330,P=0.001,P0.05)。结论椎基底动脉压迫型VP患者NVCC压迫点距前庭蜗神经出脑干处距离较近且双侧椎动脉血管直径变异度较大。
[Abstract]:Objective to investigate the magnetic resonance imaging features of vertebrobasilar artery compression vestibular paroxysma. Methods Sixty-four patients with vestibular paroxysma (vestibular paroxysmia,VP) were divided into non-vertebrobasilar artery compression group (control group) and vertebrobasilar artery compression group (observation group). The neurovascular compression (neurovascular cross-compression,NVCC) around the vestibulocochlear nerve and its compression type were determined in 64 patients. The shortest distance between the NVCC compression point and the brainstem of the vestibular cochlear nerve and the diameter of the basilar artery and bilateral vertebral artery between the two groups were analyzed. The variation of bilateral vertebral artery diameter was analyzed statistically. Results the distance from the point of NVCC compression to the brainstem of vestibular cochlear nerve in the observation group was (6.26 卤2.02) mm significantly lower than that in the control group (8.17 卤1.98) mm (), and the diameter of the vertebral artery was (3.53 卤0.42) mm in the observation group and (3.44 卤0.31) mm in the control group, and the diameter of the basilar artery in the observation group was (3.74 卤0.41) mm. There was no significant difference between the observation group and the control group (3.65 卤0.29) mm (t = 0.992P < 0.05), while the variation of the bilateral vertebral artery diameter in the observation group (1.09 卤0.31) mm was significantly higher than that in the control group (0.82 卤0.35) mm (/ min, 3.330) mm (/ min, P 0.05). Conclusion the NVCC compression point of VP patients with vertebrobasilar artery compression is close to the brainstem of the vestibulocochlear nerve and the variation of the diameter of bilateral vertebral artery vessels is greater.
