【摘要】：目的探討前庭陣發(fā)癥的磁共振表現(xiàn)。方法應用三維-磁共振血管成像技術(shù)對28例前庭陣發(fā)癥(vestibular paroxysmia,VP)患者(VP組)及28例其他眩暈病患者(對照組)進行掃描,評判所見前庭蝸神經(jīng)周圍有無神經(jīng)血管交互壓迫(neurovascular cross-compression,NVCC)現(xiàn)象,并記錄責任血管和責任血管壓迫神經(jīng)部位至腦干的距離。分別進行卡方檢驗和t檢驗以明確兩組差異之間有無統(tǒng)計學意義。結(jié)果 VP組56耳中存在NVCC現(xiàn)象有35耳,其中血管接觸關(guān)系28耳,推移關(guān)系7耳,對照組56耳中存在NVCC現(xiàn)象有16耳,均為接觸關(guān)系,未發(fā)現(xiàn)前庭蝸神經(jīng)受血管推移現(xiàn)象,兩組比較差異有統(tǒng)計學意義(χ2=16.191,P0.001)。VP組中責任血管為小腦前下動脈25耳(71.4%),小腦后下動脈7耳(20%),椎動脈3耳(8.6%),對照組中責任血管為小腦前下動脈9耳(56.3%),小腦后下動脈6耳(37.5%),椎動脈1耳(6.3%),VP組與對照組壓迫責任血管來源差異無統(tǒng)計學意義(χ2=1.774,P0.05)。NVCC距腦干距離VP組為8.57±5.08 mm,對照組為8.93±4.64 mm,兩組差異無統(tǒng)計學意義(t=-0.237,P0.05)。VP組NVCC壓迫位置距腦干距離15 mm者為29耳(82.9%),對照組NVCC壓迫位置距腦干距離15 mm者為12耳(75%),兩組差異無統(tǒng)計學意義(P=0.705,P0.05)。結(jié)論 NVCC在VP患者中發(fā)生率高,壓迫血管以小腦前下動脈多見,NVCC多發(fā)生在前庭蝸神經(jīng)中樞髓鞘部。
[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 鹵5.08 mm in VP group and 8.93 鹵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.
