摘　　要：目的探讨永存三叉动脉(PTA)伴发血管性病变的CTA和MRA影像学特点。方法回顾性分析54例经CTA和MRA检查出的PTA的影像学资料,分析其分型、变异及伴发的其他血管性病变等。结果 54例PTA患者的平均发病年龄为(59.72±16.32)岁,女多于男,左侧发病率高于右侧。Weon分型Ⅰ型16例(29.63%),Ⅱ型7例(12.96%),Ⅲ型16例(29.63%),Ⅳ型11例(20.37%),Ⅴ型4例(7.41%)。Salas分型外侧型高于中间型。合并动脉瘤16例(29.63%),破裂3例(18.75%)。合并烟雾病3例(5.56%),合并椎-基底动脉发育不良39例(72.22%),合并胚胎型大脑后动脉33例(61.11%)。伴有脑梗死29例(53.7%),脑出血4例(7.4%),蛛网膜下腔出血3例(5.56%)。脑动脉粥样硬化伴不同程度狭窄17例(31.48%)。2例伴有三叉神经痛(3.7%),动眼神经麻痹1例(1.85%)。结论 CTA和MRA可用于显示PTA的解剖特点及其分型,并能清楚地显示及评价PTA伴发的血管性病变。Objective To explore CTA and MRA characteristics of persistent trigeminal artery (PTA) with vascular disease' Methods 54 patients diagnosed as PIA by CTA and MRA were collected ret respectively, whose classification, variation and associated vascular disease were analyzed.Results There were more females than males in 54 patients,whose average age was 59.72+16.32,and the incidence of left ones were higher than that of the right ones.Type Ⅰ of Weon classification was 16 cases (29.63%), type Ⅱ 7 eases (12,96%), type Ⅲ 16 cases (29.03%).type Ⅳ 11 cases (20,37%).type Ⅴ 4 eases (7,41%).The lateral type of Salas classification was significantly higher than that in the middle type.There were 10 crises (29.63%) with aneurysm, in which 3 rases (13.70%) were rupture. 3 cases were with moymnoyu disease (5,56%).39 eases (72.22%) were with basilar artery dysplasia. There were 33 cases (61.11%) with the postembryome cerebral nrtcry.Thcrc were 29 eases with cerebral infarction (53.7%), 4 cases with cerebral hemorrhage (7.4%),3 cases with subarachnoid hemorrhage (5.56%).Cerebral arteriosclerosis with different degrees of stenosis was showed in 17 cases (31.48%). 2 cases were accompanied with trigeminal neuralgia (3.7%), and only 1 case was with ocular nerve palsy (1.85 %).Conclusion CTA and MRA could he used to display the anatomical features and radiographic classification of PTA ,and also clearly display anil evaluate PTA assnriated with vascular disease.
