Fifty-three patients with portal venous hypertension underwent angiographic evaluation of the portal venous system. Arteriography was found to provide adequate opacification of the portal system in 52 patients. Arterial portography is a safer method than splenoportography and provides informaiton not obtainable by the latter method. Thus, hepatic arteriography demonstrated 2 unsuspected hepatomas in the present series. Catheterization of the hepatic veins and measurement of the wedged hepatic venous pressure provide a reliable estimate of the total portal pressure and of the severity of the portal venous hypertension. Vena caval pressure measurements and inferior vena cavography are helpful in the diagnosis of surprahepatic causes of portal hypertension, such as constrictive pericarditis and inferior vena caval diaphragm, and are also useful in the diagnosis of vena caval hypertension due to caudate lobe enlargement. Combined arteriography and venous studies are recommended as the initial radiological approach in all patients with portal hypertension who are being considered for portal-systemic shunt surgery.
53例门静脉高压患者接受了门静脉系统的血管造影评估。结果发现，动脉造影能使52例患者的门静脉系统充分显影。动脉门静脉造影术是一种比脾门静脉造影术更安全的方法，且能提供后者无法获得的信息。因此，在本系列研究中，肝动脉造影显示出2例未被怀疑的肝癌。肝静脉插管及测量肝静脉楔压可可靠地估计门静脉总压力及门静脉高压的严重程度。腔静脉压力测量及下腔静脉造影有助于诊断肝上型门静脉高压的病因，如缩窄性心包炎和下腔静脉隔膜，也有助于诊断由于尾状叶增大导致的腔静脉高压。对于所有考虑进行门体分流手术的门静脉高压患者，建议将动脉造影和静脉研究相结合作为初始的放射学检查方法。
