Variant Anatomy of The Portal Vein According to 3D Modeling Data

The study aimed to evaluate the variant anatomy of the portal vein based on computed tomography. Materials and methods. The material ‎was the results of 224 multispiral computed tomography of abdominal organs from the archive of clinics of Samara State Medical Universi-‎ty (Samara, Russia) for 2018-2019. Plug-ins were used in the Luch and Avtoplan programs to mathematically model and create 3D models ‎of the vascular bed. These programs make it possible to obtain 3D models based on multispiral computed tomography data. The portal vein ‎confluence variant and angle parameters formed by the trunk and roots of the portal vein were studied, considering the gender and age of the ‎patients. Results. The study found that type A confluence occurred in 45.5% of cases. Type B confluence was detected in 26.8%. Type C ‎confluence occurred in 16.5%. There were no statistically significant differences in the angles formed by the trunk and roots of the portal ‎vein in patients of different age groups and genders. Portal vein type A division was detected in 71.9% of observations, and portal vein type ‎B division was detected in 20.1%‎.
