目的：探讨永存颈内-基底动脉吻合血管的 CT 血管造影(CTA)及 MR 血管造影(MRA)影像学表现并分析其临床意义。方法回顾性分析17例经头颈 CTA 及 MRA 诊断为永存颈内-基底动脉吻合血管患者的影像学资料。10例患者行头颈联合 CTA检查,7例患者行颅脑和颈部 MRA 检查,其中3例同时行 CTA 及 MRA 检查。结果永存三叉动脉(PTA)10例,按 Saltzman 分型：6例Ⅰ型,2例Ⅱ型,2例Ⅲ型。永存舌下动脉(PHA)3例,1例起始于右侧颈内动脉颈段,2例起始于左侧颈外动脉。寰前节间动脉(PIA)4例,2例位于右侧,2例位于左侧。1例 PTA 及1例 PHA 合并前交通动脉瘤。6例 PTA、2例 PHA 及1例 PIA 伴发基底动脉或椎动脉发育不良。结论CTA 及 MRA 能清楚显示永存颈内-基底动脉吻合血管的行程及其伴发颅内畸形血管合并症,为外科及介入手术提供准确的影像资料和指导作用。

Objective To explore the appearance of CT angiography(CTA)and magnetic resonance angiography (MRA)in persis-tent carotid-basilar artery anastomoses,and discuss its clinical significance.Methods 1 7 patients of persistent carotid-basilar artery anastomoses diagnosed by CT and MR angiography were retrospectively reviewed.10 patients were examined by craniocervical CTA, 7 patients were examined by cranial and cervical MRA,and 3 patients were examined by CTA and MRA.Results 10 patients had persistent trigeminal arteries (PTA).Based on Saltzman type:6 cases were Saltzman type Ⅰ,2 cases were Saltzman typeⅡ,and 2 cases were Saltzman type Ⅲ.1 case of 3 persistent hypoglossal arteries(PHA)originated from the right carotid artery,and 2 cases originated from the left external carotid artery.2 cases of 4 proatlantal intersegmental artery(PIA)were right ipsilateral,and 2 cases were left ipsilateral.1 case of PTA and 1 case of PHA associated with an aneurysm.6 cases of PTA,2 cases of PHA and 1 case of PIA complicated with ipsilateral vertebral arteries artopied or hypoplasia of the contralateral vertebral artery.Conclusion CTA and MRA can demonstrate clearly the course of persistent carotid-basilar artery anastomoses and its complicating intracranial coexisting abnormalities.Diagnosis of this anatomic variation may be helpful for providing reliable data to the guidance of surgery and interven-tional treatment.
