Abstract：
Persistent double dorsal aorta is an extremely rare congenital anomaly, with only 13 cases published to date. The objective of this study is to present this embryological variant as observed in the abdominal aorta of a patient. The anatomical description was written up on the basis of a review of electronic medical records and imaging exams. The patient in this case was an elderly 79-year-old man who presented at emergency with pain at rest in the left lower limb. He was admitted and laboratory tests and imaging exams were ordered. The variation was an imaging finding observed on angiotomography, consisting of complete separation of the abdominal aorta into two portions - a ventral and a dorsal, with different calibers - at the level of the third lumbar vertebra. There was also an anomalous origin of the inferior mesenteric artery.
摘要：
持续性双背主动脉是一种极为罕见的先天性异常,到目前为止，只有13个案例被公布。这项研究的目的是提出在患者腹主动脉中观察到的这种胚胎学变体。解剖描述是在电子病历和影像学检查的基础上编写的。这种情况下的患者是一名79岁的老人，在紧急情况下出现左下肢休息时疼痛。他被录取，并下令进行实验室检查和成像检查。变异是在血管造影上观察到的影像学发现，包括腹主动脉完全分离成两个部分-腹侧和背侧，具有不同的口径-在第三腰椎的水平。肠系膜下动脉也有异常起源。
