摘　　要：目的观察副肝静脉在布-加综合征(Budd-Chiari syndrome,BCS)中的超声表现并探讨其病变类型。方法随机超声检查244例BCS患者,观察副肝静脉(本组主要包括肝尾叶静脉和右后下静脉)的数量、走行、管腔内径、血流动力学变化以及病变类型。结果 191例BCS患者检出副肝静脉。其中142例检出尾叶静脉,132例检出右后下肝静脉。191例中83例同时检出尾叶静脉和右后下肝静脉。副肝静脉的血流速度及血流频谱形态受病变肝静脉侧支汇入的多少和下腔静脉的通畅程度影响。副肝静脉病变25例,主要为管腔狭窄和血栓。结论超声检查能明确副肝静脉及其病变,对BCS治疗也具有重要意义。Objective To study the ultrasonic features of accessory hepatic veins （AHVs） in Budd Chiari syndrome （BCS） . Methods Two hundred and fourty-four patients with BCS were examed by ultrasound randomly. The quantity, courser, diameter, haemodynamics were observed both in normal and abnormal AHVs including caudate lobe veins （CLVs） and the inferior right hepatic veins （IRHVs） . Results One hundred and ninety-one patients with AHVs were displayed in this group. The CLVs and the IRHVs were in 142 and 132 out of 191 patients respectively. Among 191 patients mentioned above, both CLVs and IRHVs were detected simultaneously in the same patient in 83 cases. Haemodynamics of AHVs was influenced by the quantity of collaterals drainaged to them and the lumen af- fection of IVC. Affections of IRHVs found in 25 patients were mainly luminal stenosis and thrombosis. Conclusions Ultrasonic demonstration of AHVs and their affections are very important for the treatment of BCS.
