PURPOSE
To present a peculiar anatomic portal veins variant and evaluate its clinical implications.
METHODS
Among 118 consecutive patients undergoing transjugular intrahepatic portosystemic shunting (TIPS), six male patients were found to have an accessory portal vein, which was seen during direct portography.R ESULTS: In all six patients, portograms showed an accessory small-caliber vein parallel to the trunk of the main portal vein ending in the right lobe of the liver. Two of the six accessory portal veins drained blood from coronary veins, precluding access to coronary vein embolization during TIPS.
CONCLUSION
An accessory portal vein is a rare anatomical variation with clinical significance for both surgical shunt placement and TIPS, as well as for transportal embolization of coronary veins.
目的
呈现一种特殊的解剖学门静脉变异并评估其临床意义。
方法
在118例连续接受经颈静脉肝内门体分流术（TIPS）的患者中，6例男性患者被发现存在副门静脉，这是在直接门静脉造影时发现的。
结果
在所有6例患者中，门静脉造影显示一条与主门静脉主干平行的小口径副静脉，止于肝右叶。6条副门静脉中有2条引流冠状静脉的血液，这使得在TIPS期间无法进行冠状静脉栓塞。
结论
副门静脉是一种罕见的解剖变异，对手术分流置入和TIPS以及冠状静脉的经门静脉栓塞均具有临床意义。
