副肝静脉在Budd-Chiari综合征诊断与治疗中的价值

The value of accessory hepatic vein in Budd-Chiari syndrome

目的探讨副肝静脉的影像学诊断标准，评价副肝静脉在Budd-Chiarih综合征诊断与治疗中的价值。方法通过100例下腔静脉和（或）肝静脉造影，观察副肝静脉的发生率，测量副肝静脉主干和口部的直径，观察33例离体肝脏标本中副肝静脉的发生率，测量副肝静脉口部的直径。结果副肝静脉在Budd-Chiari综合征中的发生率为69％，主干和开口直径为12．5±5mm。副肝静脉在肝脏标本中的发牛率为57％，开口直径为7．0±2.9mm，副肝静脉开口在Budd-Chiari综合征时明显大于肝脏标本（P＜0.01）、结论副肝静脉在肝静脉阻塞时起到代偿肝脏血液回流的作用。作者肯定了副肝静脉的影像解剖、影像了诊断在Budd-Chiari综合征的诊断与治疗中的价值。

Purpose To investigate the imaging standard of the accessory hipatic vein and to evaluate the accessory hepatic vein in diagnosing and treating Budd-Chiari syndrome Methods 100 inferior cava and /or hepatic venographies were performed. 33 venographies hepatic specimens were observed. The ostial diameter of the accessory hepatic vein was measured in the venographs and hepatic The statisitical of the accessory hepatic vein was also discussde. Rasults The rate of accessory hopatic' vein was 69% and its ostial diameter was 12.5±5.0 mm in our patiellts with Buddd-Chiari ayndrome. The rate of accessory hepatic vein was 57%and its ostial diamleter was 7. 0 ±2. 9 mm in the hepatic specimens. The differance of the ostium was sigrnificant (P 〈0.01 ). Conclusion The accessory hepatic vein ean also drain hepatic blood compesatively in hepatic vein ohstruction. The imaging anatomy and imaging diagnosis of accessory nepatic vein ,the value of the accessory hepatic vein in diagnosing and treating Budd_Chiari syndrome were discussed.
