Abstract

BACKGROUND

The aim of this retrospective and monocentric study was to describe the magnetic resonance cholangiography (MRC) features of biliary abnormalities related to extrahepatic obstruction of the portal vein (EHOPV).

METHODS

From September 2001 to May 2003, MRC was performed in 10 consecutive patients who had a portal thrombosis.

RESULTS

Biliary ductal pathology was demonstrated via MRC in nine patients. It consisted of stenoses, ductal narrowing or irregularities involving the common bile duct for three patients with extrahepatic portal vein thrombosis discovered a mean of 1.5 years ago, or involving both right and left intrahepatic bile ducts and common bile duct for six patients with extrahepatic portal vein thrombosis discovered a mean of 16.2 years ago. Dilation of intrahepatic bile ducts was seen for seven patients, four of them having cholestasis. For three patients with symptomatic cholestasis, direct cholangiography (DC) was performed and showed the same findings as MRC which nevertheless overestimated the degree of bile duct stenosis.

CONCLUSIONS

MRC seems to constitute an accurate tool to investigate noninvasively patients with portal biliopathy.

摘要

背景

本回顾性单中心研究旨在描述与肝外门静脉阻塞（EHOPV）相关的胆道异常的磁共振胆胰管造影（MRC）特征。

方法

2001年9月至2003年5月，对10例连续性门静脉血栓形成患者进行了MRC检查。

结果

9例患者通过MRC显示出胆管病变。病变包括狭窄、导管狭窄或不规则，3例平均1.5年前发现肝外门静脉血栓形成的患者病变累及胆总管，6例平均16.2年前发现肝外门静脉血栓形成的患者病变累及左右肝内胆管及胆总管。7例患者可见肝内胆管扩张，其中4例有胆汁淤积。对3例有症状胆汁淤积的患者进行了直接胆管造影（DC），结果与MRC相同，但MRC高估了胆管狭窄程度。
