Abstract

Purpose: 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.

Methods: 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.

Results: 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).

Conclusions: 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.

儿童及青少年正常门静脉内径的腹部增强CT评价。

目的：建立儿童和青少年门静脉主静脉（MPV）、左门静脉（LPV）和右门静脉（RPV）腹部增强CT的正常范围。方法：回顾性招募2018年1月至2024年1月在我院接受腹部CT增强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受试者。收集受试者的性别和年龄。身高、体重和体表面积（BSA）也被收集。在肝门、中点、肠系膜上静脉与脾静脉汇合处三个点测量MPV直径。测量LPV直径和RPV直径。分析年龄、身高、体重、BSA与门静脉直径的相关性。结果：共纳入1231人，其中男生722人，女生509人，中位年龄10岁。获得189名个体的身高、体重和BSA信息。建立不同年龄、身高、体重、BSA组MPV、LPV、RPV的正常范围。MPV、LPV、RPV直径与年龄、身高、体重、BSA均呈正相关（均P）。结论：本研究建立了儿童及青少年基于CT增强扫描的MPV、LPV、RPV直径的正常参考范围，有助于肝胆疾病的诊断和治疗。
