永存三叉动脉伴发脑血管性病变及其他脑部疾病

Persistent primitive trigeminal artery associated with cerebrovascular diseases and other cerebrosis

永存三叉动脉(PPTA)是成人最常见的一种永久性颈内动脉和基底动脉之间的异常吻合,是一种较罕见的脑血管变异。PPTA经常伴发脑血管性病变,并且可引起三叉神经痛,动眼神经、外展神经麻痹,蛛网膜下腔出血等症状,与临床关系较为密切。本文对1983年至今中英文文献报道的116例PPTA伴发脑血管性病变及其他脑部疾病的病例进行总结。

Persistent primitive trigeminal artery （PPTA） is the most common permanent abnormal vascular anastomosis between carotid artery and basilar artery. PPTA is a rare cerebrovascular variation and is often associated with cerebrovascular disease （CVD）. Clinically, PPTA manifests itself in symptoms such as trigeminal neuralgia, oculomotor paralysis, abdueens nerve paralysis, subarachnoid hemorrhage, etc. This paper aims to review 116 PPTA cases with CVD and other cerebrosis, which have ever been reported since 1983 in English or Chinese medical literature.
