目的分析下腔静脉阻塞膜与肝右静脉的位置关系,探讨Budd-Chiari综合征(BCS)可能的病因学。方法 35例下腔静脉IVC膜性阻塞性病变患者,DSA观察下腔静脉CIVC阻塞膜与肝静脉的位置关系。结果膜位于肝右静脉以上者32例,肝右静脉以下者3例。膜位于肝右静脉与肝左、中静脉之间者3例,位于三支HV以上者4例。结论某些低毒性物质的作用和IVC壁的损伤可能为BCS发病的始动因素。
Objective To analyze the relationship between the inferior vena cava occlusive membrane and the right hepatic vein and to explore the possible etiology of Budd-Chiari syndrome (BCS). Methods 35 patients with inferior vena cava IVC membranous obstructive lesions were examined by DSA for the relationship between the inferior vena CIVC obstruction membrane and the hepatic veins. Results The membrane located above the right hepatic vein in 32 cases, right hepatic vein in 3 cases. Membrane located in the right hepatic vein and left and middle hepatic vein in 3 cases, located in more than three HV in 4 cases. Conclusion The action of some low toxic substances and the damage of IVC wall may be the initiating factors of BCS.
