Increasing precision of liver resection and use of reduced liver grafts stimulated this study of the blood supply of the intrahepatic bile ducts.
Corrosion casts of human liver were dissected to study the blood supply of the right and left hepatic ducts.
The dissected casts showed that the ducts are surrounded by a vascular plexus supplied from the main right and left hepatic arteries, segmental arteries, gastroduodenal artery and accessory hepatic arteries. This plexus is closely associated with the arteries supplying the caudate lobe. They arise from both right and left in two general patterns. This plexus links the arterial supplies of the right and left livers. Segment i.v. and the central portion of the left hepatic duct are often supplied by the right arterial system.
This study provides further insights into bile duct blood supply. The caudate lobe and biliary plexus provide collateral connections between the right and left livers.
肝脏切除精度的提高以及缩小肝移植的使用促使了对肝内胆管血液供应的这项研究。
解剖人体肝脏的铸型标本以研究左右肝管的血液供应。
解剖后的铸型标本显示，胆管被一个血管丛包围，该血管丛由左右肝固有动脉、肝段动脉、胃十二指肠动脉和副肝动脉供血。这个血管丛与供应尾状叶的动脉密切相关。它们以两种一般模式从左右两侧发出。这个血管丛连接左右肝脏的动脉供应。肝段IV和左肝管的中央部分通常由右侧动脉系统供血。
本研究为胆管血液供应提供了进一步的见解。尾状叶和胆管丛在左右肝脏之间提供了侧支连接。
