【摘要】：目的探讨前庭阵发症的磁共振表现。方法应用三维-磁共振血管成像技术对28例前庭阵发症(vestibular paroxysmia,VP)患者(VP组)及28例其他眩晕病患者(对照组)进行扫描,评判所见前庭蜗神经周围有无神经血管交互压迫(neurovascular cross-compression,NVCC)现象,并记录责任血管和责任血管压迫神经部位至脑干的距离。分别进行卡方检验和t检验以明确两组差异之间有无统计学意义。结果 VP组56耳中存在NVCC现象有35耳,其中血管接触关系28耳,推移关系7耳,对照组56耳中存在NVCC现象有16耳,均为接触关系,未发现前庭蜗神经受血管推移现象,两组比较差异有统计学意义(χ2=16.191,P0.001)。VP组中责任血管为小脑前下动脉25耳(71.4%),小脑后下动脉7耳(20%),椎动脉3耳(8.6%),对照组中责任血管为小脑前下动脉9耳(56.3%),小脑后下动脉6耳(37.5%),椎动脉1耳(6.3%),VP组与对照组压迫责任血管来源差异无统计学意义(χ2=1.774,P0.05)。NVCC距脑干距离VP组为8.57±5.08 mm,对照组为8.93±4.64 mm,两组差异无统计学意义(t=-0.237,P0.05)。VP组NVCC压迫位置距脑干距离15 mm者为29耳(82.9%),对照组NVCC压迫位置距脑干距离15 mm者为12耳(75%),两组差异无统计学意义(P=0.705,P0.05)。结论 NVCC在VP患者中发生率高,压迫血管以小脑前下动脉多见,NVCC多发生在前庭蜗神经中枢髓鞘部。
[Abstract]:Objective to investigate the MRI findings of vestibular paroxysma.Methods Twenty eight patients with vestibular paroxysmia VP (VP group) and 28 patients with other vertigo (control group) were scanned by three-dimensional magnetic resonance angiography (MRA). The neurovascular cross-compression (NVCC) phenomenon around the vestibular cochlear nerve was evaluated.The distance between the responsible blood vessel and the responsible blood vessel from the nerve to the brain stem was recorded.Chi-square test and t-test were performed to determine whether there was statistical significance between the two groups.Results there were 35 ears with NVCC in 56 ears of VP group, including 28 ears with vascular contact, 7 ears with NVCC, and 16 ears with NVCC in 56 ears of control group. No vestibular cochlear nerve was found to be vascularized.The difference between the two groups was statistically significant (蠂 ~ 2 / 16.191 / P 0.001N. VP group): 25 ears of anterior inferior cerebellar artery, 71.4% of inferior cerebellar artery, 7 ears of posterior inferior cerebellar artery, 20 ears of posterior inferior cerebellar artery and 8.6% of vertebral artery. In the control group, the responsible vessels were 9 ears of anterior inferior cerebellar artery and 56.33 ears of posterior inferior cerebellar artery, and 6 ears of posterior inferior cerebellar artery.There was no significant difference in the origin of responsible vessels between the VP group and the control group (蠂 ~ 2 / 1.774) (P 0.05). The distance from brain stem to brain stem was 8.57 卤5.08 mm in VP group and 8.93 卤4.64 mm in control group. There was no significant difference between the two groups in the distance between NVCC compression position and brainstem. There was no significant difference between the two groups in the distance from the NVCC compression position to the brainstem (15 mm).In the control group, the distance from the NVCC compression position to the brainstem was 15 mm and 12 ears were 75. There was no significant difference between the two groups. There was no significant difference between the two groups (P < 0. 705 and P 0. 05).Conclusion the incidence of NVCC in VP patients is high, and the compression vessels are more common in the central myelin sheath of the vestibulocochlear nerve center than in the anterior inferior cerebellar artery.
