To study the variations of the right branch of the hepatic portal vein in children.
A total of 810 children's abdominal CT images were reconstructed with three-dimensional (3D) simulation software, Variations of the right branch of the hepatic portal vein were analyzed and classified.
The most common anatomy (type A) was seen in 355 patients (43.83%). Trifurcation in the right anterior portal vein (type B) variation was seen in 250 cases (30.86%). The right posterior portal vein arched without obvious branching (type C) was seen in 71 cases (8.77%). There were 134 special variants (16.54%) named type D, including 14 cases (1.73%) with the right anterior branch in four sub-branches, 13 cases (1.60%) in one trunk and multiple sub-branches, 92 cases (11.36%) originating from the left trunk of the portal vein, and 15 cases (1.85%) with the VI segment of the portal vein originating from the right anterior branch of the portal vein.
Variations in the right branch of the hepatic portal vein seems to be very frequent. Recognition of such variations is important in the preoperative evaluation of children with surgery planned, because these variations may have implications for anatomy-guided liver resection and for planning the operative approach.
研究儿童肝门静脉右支的变异情况。
利用三维（3D）模拟软件重建 810 例儿童腹部 CT 图像，分析并分类肝门静脉右支的变异情况。
最常见的解剖结构（A型）见于 355 例患者（43.83%）。250 例患者出现右前支门静脉三分叉（B 型）变异。71 例患者（8.77%）出现右后支门静脉无明显分支的弓状弯曲（C 型）。134 种特殊变异（16.54%）被命名为 D 型，包括 14 例（1.73%）右前支分为 4 个分支，13 例（1.60%）为单干多支，92 例（11.36%）起自门静脉左干，15 例（1.85%）门静脉 VI 段由门静脉右前支发出。
肝门静脉右支的变异似乎非常频繁。在计划手术的儿童术前评估中，识别这些变异非常重要，因为这些变异可能对解剖指导下的肝切除术和手术入路的规划有影响。
