The diameters of the abdominal aorta and its branches are affected by demographic properties of patients like age, sex or body mass index. Some researchers use the body of the first lumbar vertebra (L1) as an anatomical indicator to create an exact standard for diagnosing arterial aneurysms or stenoses. In this regard, this work designed to uncover relations of abdominal visceral arteries with L1 in normal children using their abdominopelvic computed tomography images.
The study population consisted of 180 subjects (age range 1-18 years) without any abdominopelvic disorders. The diameters of the abdominal visceral arteries were measured and the ratios of these arteries to L1 were calculated.
The diameters of the abdominal visceral arteries increased from infancy period up to postpubescent period (p < 0.001), but L1's diameter did not change after late childhood period. Measurements in males were statistically similar to those in females, excepts from the transverse diameter of L1 (p = 0.001), the diameter of the common hepatic artery at the distal level (p = 0.002), and the diameter of the inferior mesenteric artery at the distal level (p = 0.019), which were greater in males than females. The ratios of diameters of the abdominal visceral arteries to L1 increased with advancing age (p < 0.001). Ratios in males were statistically similar to those in females (p > 0.05).
Our age-specific diameters and ratios regarding abdominal visceral arteries may facilitate the diagnosis of vascular disorders in children.
腹主动脉及其分支的直径受患者年龄、性别或体重指数等人口统计学特征的影响。一些研究人员将第一腰椎（L1）的椎体作为解剖学指标，以制定诊断动脉瘤或狭窄的精确标准。在这方面，本研究旨在利用正常儿童的腹部盆腔计算机断层扫描图像，揭示腹内脏器动脉与L1之间的关系。
研究对象为180名无任何腹部盆腔疾病的受试者（年龄范围1 - 18岁）。测量腹内脏器动脉的直径，并计算这些动脉与L1的比值。
腹内脏器动脉的直径从婴儿期到青春期后期逐渐增加（p < 0.001），但L1的直径在儿童晚期后没有变化。男性的测量结果与女性在统计学上相似，但L1的横径（p = 0.001）、肝总动脉远端水平的直径（p = 0.002）和肠系膜下动脉远端水平的直径（p = 0.019）除外，这些在男性中大于女性。腹内脏器动脉与L1的直径比值随年龄增长而增加（p < 0.001）。男性的比值与女性在统计学上相似（p > 0.05）。
我们关于腹内脏器动脉特定年龄的直径和比值可能有助于儿童血管疾病的诊断。
