摘　　要：目的分析和探讨巨长基底动脉的临床特点和多种成像方法的诊断价值.方法对4例巨长基底动脉患者的临床资料进行回顾性分析.结果巨长基底动脉为一少见病,无特异临床表现,CT、CTA、MRI、MRA、DSA检查可以发现巨长基底动脉.结论CT是诊断MDBA较直观、简捷、经济、安全的无创方法.MRI能清楚显示基底动脉的异常血管结构,以及周围颅神经或脑组织的受压改变.CTA、MRA可以直观显示迂曲延长、增粗的血管全貌.CT、CTA、MRI、MRA相结合,有助于对该病的综合评价.Objective To analyze and investigate the clinical charactertistics and the diagnostic value of synthetic imaging in megadolichobasilar artery. Methods The clinical data of 4 patients with megadolichobasilar artery were analyzed retrospectively. Meanwhile, relevant literatures were reviewed. Results Megadolichobasilar artery is an infrequent illness and has no special clinical manifestation. It was found by CT, CTA, MRI, MRA, DSA. Conclusions CT is more intuitive, simple, economic, safe, non-invasive method in diagnosis of megadolichobasilar artery. MRI can clearly demonstrate the abnomal arterial structures of vertebrobasilar artery and the secondary compression of adjacent brain tissue and cranial nerves. CTA and MRA can display full view of the elongated, widened and tortuous arteries. The combination of CT and CTA, MRI, MRA is helpful for synthetic assessing this disease.
