目的：探讨肝静脉阻塞之下腔静脉造影征象及临床意义。方法：２３例肝静脉阻塞患者，采用股静脉穿刺插管行下腔静脉造影，分析肝静脉开口征象并指导临床治疗（ＰＴＡ和ＥＭＳ）。结果：２３例患者中，杯口征１０例，指压迹征３例，盲袋征４例，未显示６例。采用腔静脉途径开通肝静脉１４例。结论：识别阻塞肝静脉造影征象是介入治疗的关键。杯口征和指压迹征皆易开通，盲袋征和未显示者开通则较难
Objective: To investigate the signs and clinical significance of inferior vena cava angiography in hepatic vein occlusion. Methods: Twenty - three patients with hepatic vein occlusion were treated with femoral venous catheterization through inferior vena cava angiography to analyze the signs of hepatic venous opening and to guide the clinical treatment (PTA and EMS). Results: In 23 cases, there were 10 cases of cup mouth sign, 3 cases of finger pressure sign, 4 cases of blind bag sign and 6 cases of no sign. The use of vena cava hepatic vein opened in 14 cases. Conclusion: Identification of obstructive hepatic venography is the key to interventional therapy. Cup mouth sign and finger pressure sign are easy to open, blind bag sign and not shown are more difficult to open
