摘要
目的 评价静脉造影、MR、多普勒超声对肝静脉阻塞型 Budd -Chiari综合征的诊断价值。方法 回顾性分析35例肝静脉阻塞型 Budd- Chiari综合征的静脉造影、MR、多普勒超声表现,比较三种检查方法显示该组病例肝脏形态、肝静脉、肝内侧支血管情况。结果 MR显示肝脏特别是尾叶体积增大, 肝脏信号不均,显示有肝内侧支血管。多普勒超声显示肝静脉狭窄或阻塞,显示有肝内侧支血管,显示有肝外侧支血管如脐静脉重开。正确全面的静脉造影可以确诊肝静脉阻塞、并可显示下腔静脉狭窄等间接征象。结论 MRI对显示肝脏形态、阻塞部位性质较为敏感,多普勒超声则对显示肝静脉狭窄或阻塞、肝内侧支血管有优势,有助于该病的临床初筛,静脉造影作为 Budd- Chiari综合征介入治疗的重要步骤,诊断意义重大。静脉造影与MR、多普勒超声相互补充有助于本病的正确诊断具备指导意义。
Objective To evaluate venography, MR and sonography in diagnosis of BCS of obstruction of hepaticveins. Methods The MR, sonographic and venographic data of 35 cases with BCS of obstruction of hepaticveins were retrospectively studied. The findings of hepatic morphology, hepaticveins and collateral vessel on these three imaging modalities were compared. Results MR showed caudate lobe enlage, intrahepatic collateral vessels. Sonography demonstrated narrowing or obstruction of the hepatic veins, intra hepatic collateral vessels and extra hepatic collateral vessels such as the reopening of umbilical vein. Correct and full venography can diagnose obstruction of hepatic veins and show indirect signs such as norrowing of IVC. Conclusion MR has superiority in delineating hepatic morphology, character of obstruction. Sonography has superiority in demonstrating the direct signs of narrowing or obstruction of the hepaticveins and intra hepatic collateral vessels. As an important step of interventional therapy, venography is necessary. The complementarity of MR, sonography and venography is helpful in the diagnosis of BCS.
