Persistent trigeminal artery (PTA), also called primitive trigeminal artery, represents the most common embryonic remnant of fetal circulation in adulthood, (only after fetal pattern of posterior communicating artery [PComA]) with an estimated incidence of between 0.1% and 0.76%. The permanence of this fetal pattern constitutes an incidental finding in most cases, however, may be associated with aneurysms, arteriovenous malformations, trigeminal neuralgia, and other types of fetal circulation persistency. A patient with giant aneurysm in the communicating segment of the right internal carotid artery, associated with the presence of PTA and fetal pattern of PComA, also on the right side is reported.
持续性三叉动脉（PTA），也称为原始三叉动脉，是成年期胎儿循环中最常见的胚胎残余物（仅次于胎儿型后交通动脉[PComA]），估计发病率在0.1%至0.76%之间。这种胎儿型模式的持续存在在大多数情况下是偶然发现，但可能与动脉瘤、动静脉畸形、三叉神经痛以及其他类型的胎儿循环持续性有关。本文报告了一名右侧颈内动脉交通段巨大动脉瘤患者，该患者同时伴有右侧的持续性三叉动脉和胎儿型后交通动脉。
