摘要
目的探讨幼稚型永存三叉动脉(IPTA)伴动脉瘤的多层螺旋CT血管成像(CTA)表现。方法回顾性对比分析13例IPTA的CTA和手术资料。结果 13例经手术确诊的IPTA患者中,13例均表现为颈内动脉虹吸部走行异常,9例床突上段(C2)、膝段(C3)、部分海绵窦段(C4)缺如;4例膝段(C3)、部分海绵窦段(C4)缺如;永存三叉动脉由残余海绵窦段发出,该血管分支为大脑后动脉。双侧椎动脉(颈段)显纤细,末端达正常小脑后下动脉供血区域;基底动脉未见显示。13例中有6例永存三叉动脉主干局部瘤样、梭形样扩张。结论CTA能清楚显示IPTA的走行及其周围关系,并能判定合并动脉瘤的发生部位、形态和大小及与载瘤动脉的关系,对外科手术有较好的指导作用。
[ Objective ] To explore the CTA findings of the infantile persistent trigeminal artery （IPTA） combined with arterial aneurysm. [ Methods ] Thirteen cases of IPTA identified with CTA and operation were reviewed. [ Re- suits ] Thirteen IPTA cases were diagnosed by operation, all the 13 cases manifested abnormal contour of the siphon segment of internal carotid artery （ICA）, 9 cases depicted absence of the supraclinoid （（：2）, bend （C3） and cavernous segment （C4） of ICA, 4 eases depicted absence of the bend （C3） and partial cavemous segment （C4） of ICA. The ori- gin of the persistent trigeminal artery （lYFA） is usually in the posterior or lateral surface of the intraeavernous ICA, of which the branch is posterior cerebral artery （PCA）. Bilateral vertebral artery revealed stenosis. Main branches of PTA were dilated in six cases （6/13）. [ Conclusions] CTA can be a pivotal method in diagnosis and classification for IPTA by demonstrating the morphologic features clearly. The imaging diagnosis and classification of IPTA have some clinical application value.
