Emphasis on the significance of "short hepatic portal vein" anatomy in perihepatic portal surgery / 中国实用外科杂志

ABSTRACT

Perihilar area is a clinically specific anatomical area centered on the confluence of the main portal vein with the left and right branches and bounded by the "H-shaped transverse sulcus" of the liver. Its anatomical structure is complex, involving the liver, gallbladder, regional lymph nodes and luminal systems such as portal vein, hepatic artery, bile duct and inferior vena cava. It is a difficult area in hepatobiliary surgery. Therefore, a reasonable surgical approach is of great importance. The anatomical approach strategy of "Glisson intrathecal dissociation" can clearly show the anatomical structure of various luminal systems in the perihilar area, reduce the risk of surgical error injury, and contribute to the rational individualized surgical plan decision and implementation. The short hepatic portal vein is a small branch of the main, right and left branches of the portal vein and their confluence, which distributes and travels in the transverse sulcus of the liver. The anatomical characteristics of the short hepatic portal vein should not be ignored in the implementation of "Glisson intrathecal dissociation" in the perihilar area.
