To establish the normal ranges of the main portal vein (MPV), left portal vein (LPV), and right portal vein (RPV) diameters in children and adolescents using abdominal contrast-enhanced CT.
We retrospectively enrolled children and adolescents (under 19 years) who underwent abdominal contrast-enhanced CT examinations in our hospital between January 2018 and January 2024. Subjects with conditions potentially affecting the portal vein diameter were excluded. Subjects' gender and age were collected. The height, weight, and body surface area (BSA) were also collected if available. The diameter of MPV was measured at three points: porta hepatis, midpoint, and the confluence of the superior mesenteric vein and the splenic vein. The diameter of LPV and RPV were also measured. The correlations between age, height, weight, BSA, and portal vein diameters were analyzed.
A total of 1231 individuals were included, comprising 722 boys and 509 girls, with a median age of 10 years. 189 individuals' height, weight, and BSA information were obtained. The normal ranges of MPV, LPV, and RPV, depending on different age, height, weight, and BSA groups, were established. The diameters of MPV, LPV, and RPV were all positively correlated with age, height, weight, and BSA (all P < 0.001).
This study establishes the normal reference ranges for MPV, LPV, and RPV diameters in children and adolescents based on contrast-enhanced CT scans, which will help the diagnosis and treatment of hepatobiliary diseases.
利用腹部增强CT确定儿童和青少年主门静脉（MPV）、左门静脉（LPV）和右门静脉（RPV）直径的正常范围。
我们回顾性纳入了2018年1月至2024年1月期间在我院接受腹部增强CT检查的儿童和青少年（19岁以下）。排除可能影响门静脉直径的疾病患者。收集受试者的性别和年龄。如有身高、体重和体表面积（BSA）数据也一并收集。MPV直径在肝门、中点以及肠系膜上静脉与脾静脉汇合处三个点进行测量。LPV和RPV直径也进行了测量。分析年龄、身高、体重、BSA与门静脉直径之间的相关性。
共纳入1231例个体，其中男孩722例，女孩509例，中位年龄为10岁。获取了189例个体的身高、体重和BSA信息。根据不同年龄、身高、体重和BSA组建立了MPV、LPV和RPV的正常范围。MPV、LPV和RPV直径均与年龄、身高、体重和BSA呈正相关（均P < 0.001）。
本研究基于增强CT扫描建立了儿童和青少年MPV、LPV和RPV直径的正常参考范围，这将有助于肝胆疾病的诊断和治疗。
