摘要
目的 回顾性研究一种特殊类型的布加氏综合征:下腔静脉血经肝回流入右心房。方法 彩色多普勒超声检查114例布加氏综合征患者,观察下腔静脉和三支肝静脉的走行、入口和血流方向以及肝内外交流支。结果 共5例布加氏综合征患者呈现特殊循环方式,表现为肝段下腔静脉血经一支肝静脉入肝,通过肝内交通支再经另一支肝静脉回流右心房。诊断均经介入手术证实。结论 下腔静脉血经肝回流型布加氏综合征是一种少见类型,其特点是下腔静脉入口处的闭塞或重度狭窄,伴随分别开口于下腔静脉阻塞段上下方的两支肝静脉和肝内丰富的交通支。
Objective Retrospectively study a special pattern of Budd Chiari syndrome(BCS):inferior vena cava(IVC) blood flowing into right atrium via hepatic veins.Methods One hundred and fourteen patients with BCS were examined with color Doppler ultrasound.The courses,orifices and flow direction of IVC,three main hepatic veins(HVs) and the collaterals were investigated.Results Five patients with BCS were found possessing that circulation type:blood of hepatic IVC flowed into the liver through a hepatic vein,and through intrahepatic collaterals and another hepatic vein,and finally flowed into the right atrium.Diagnoses of the 5 cases were proved by interventional management.Conclusions Blood flowing of IVC via hepatic veins is a rare type of BCS.The character is the occlusion or severe stenosis of IVC accompanying two hepatic vein opened inferior and superiov to IVC obstructive segment respectively and abundant intrahepatic collaterals.Diagnosis of this special circulation pattern of BCS is significance both in vessel impairment classification and interventional strategy decision making.
