摘要
目的:分析、探讨椎动脉核磁共振血管造影(MRA)对椎基底动脉供血不足(VBI)的诊断价值和意义。方法:共65患者,男33例,女32例,年龄40～78岁,平均年龄56.85+11.07岁。符合椎基底动脉供血不足诊断标准,分别进行椎动脉MRA、TCD、BAEP及椎动脉超声等检查。结果:65例患者中椎动脉MRA异常35例(53.8％),TCD异常53例(81.5％),椎动脉B超异常33例(50.8％),BAEP异常30例(46.2％)。椎动脉MRA能清楚的显示血管病理形态,主要表现为单侧或双侧椎动脉变细、粗细不均及血流信号降低。MRA异常率与病人的病程长短有关。结论:椎动脉MRA、TCD、BAEP、椎动脉超声4种方法合用,有助于全面客观诊断椎基动脉供血不足。
Objective: The analysis of the value of MRA was performed in investigation of vertebral and basilar arteries in 65 patients with vertebrobasilar insufficiency. Methods: 65 patients were examide by MRA, TCD, BAEP and duplex ultrasonography of the same vessels. Results:MRA date were compared with the results of TCD, duplex ultra-sonography of the same vessels and BAEP. MRA showed abnormalities in 52. 8%. TCD showed abnormalities in 81, 5%. vertebro-basilar artery duplex ultrasonography showed abnormalities in 50. 8%. BAEP was abnormalities in 46. 2%. there might be a close relationship of abnormal in MRA with course. Conclusion: The results of MRA, TCD, BAEP and duplex ultrasonography of vertebral-basilar arteries will helpful for dignosis of vertebrobasilar insufficiency.
