目的 评价肝静脉阻塞的血管造影表现。方法 肝静脉阻塞患者 4 5例 ,男 2 3例 ,女2 2例 ;年龄 9～ 5 4岁。全部病例均行下腔静脉造影和肝静脉造影。结果 肝静脉阻塞而下腔静脉通畅 37例 ,肝静脉和下腔静脉同时阻塞 8例。肝静脉阻塞而下腔静脉造影表现为肝内段下腔静脉局限性或普遍性狭窄 31例 ,肝内段下腔静脉管径正常者 12例 ,肝静脉开口处出现隔膜膨出征 5例 ,副肝静脉开口处出现隔膜膨出征 4例 ,肝静脉之间交通支形成 4 5例。结论 下腔静脉造影能对肝静脉有无阻塞做出初步判断 ,隔膜膨出征是肝静脉和副肝静脉开口处膜性阻塞的直接征象 ,选择性肝静脉造影是诊断肝静脉阻塞的可靠依据。
Objective To evaluate the performance of hepatic vein occlusion angiography. Methods 45 cases of hepatic vein occlusion, 23 males and 22 females; aged 9 to 54 years old. All cases underwent inferior vena cava angiography and hepatic venography. Results Hepatic vein obstruction and inferior vena cava patency in 37 cases, hepatic vein and inferior vena cava occlusion in 8 cases at the same time. Hepatic vein occlusion and inferior vena cava angiography showed intrahepatic inferior vena cava limited or common stenosis in 31 cases, intrahepatic inferior vena cava caliber in 12 cases, hepatic venous opening diaphragm rupture in 5 cases, deputy There were 4 cases of septum bulging in the opening of hepatic veins and 45 cases of communicating branch between hepatic veins. CONCLUSIONS: IVC can be used to judge the presence or absence of occlusion of the hepatic veins. The bulging of the diaphragm is a direct indication of the membranous obstruction of the hepatic and accessory hepatic veins. Selective hepatic venography is a reliable basis for the diagnosis of hepatic vein occlusion.
