The present study aimed to examine the branching pattern images of the Hepatis Portae Vena (HPV), which is one of the vascular structures of the liver, with Computed Tomography (CT), and to uncover the surgical and radiological importance of the variations. The HPV branching patterns on CT images of healthy liver of 996 individuals (47.8% male, 52.2% female) between the ages of 20 and 59 were evaluated according to previously determined definitions. The division of the main branch of the HPV into ramus (r.), dexter, and r. sinister and the later division of r. dexter into r. anterior and r. posterior branches were called Type I-a, other main branch variations were called Type II-a, Type III-a, and Type IV-a, and the r. dexter variations were called Type V-b, Type VI-b, Type VII-b, and Type VIII-b. Also, all individuals in the present study were examined under four age groups as 20-29, 30-39, 40-49, 50-59, and the data were analyzed in the SPSS 21 software. Type I-a (73.1%) was detected most frequently in all individuals, but Type VI-b (0.1%) and Type VII-b (0.1%) were detected least frequently. Following Type I-a, Type II-a (10.6%), Type III-a (8.2%), and Type V-b (5.5%) were detected, respectively. No statistically significant differences were detected between gender and age groups in terms of the frequency of HPV types ( > 0.05). We believe that accurate knowledge and definition of HPV anatomy will guide liver surgeries and interventional radiology, which are the cornerstones of the treatment of liver diseases.
本研究旨在利用计算机断层扫描（CT）检查肝门静脉（HPV）的分支模式图像，HPV是肝脏的血管结构之一，并揭示变异的手术和放射学意义。根据先前确定的定义，对996名年龄在20至59岁之间的健康肝脏CT图像上的HPV分支模式进行了评估，其中男性占47.8%，女性占52.2%。HPV主支分为右支（r.）、右前支和右后支称为I-a型，其他主支变异称为II-a型、III-a型和IV-a型，右支变异称为V-b型、VI-b型、VII-b型和VIII-b型。此外，本研究中的所有个体按20-29岁、30-39岁、40-49岁、50-59岁四个年龄组进行检查，并在SPSS 21软件中对数据进行分析。I-a型（73.1%）在所有个体中最常被检测到，而VI-b型（0.1%）和VII-b型（0.1%）最不常被检测到。在I-a型之后，分别检测到II-a型（10.6%）、III-a型（8.2%）和V-b型（5.5%）。在HPV类型频率方面，性别和年龄组之间未检测到统计学显著差异（>0.05）。我们认为，对HPV解剖结构的准确了解和定义将指导肝脏手术和介入放射学，而这两者是肝脏疾病治疗的基石。
