The accuracy of ultrasound assessment of portal vein patency has been defined by comparing it with the results of arterial portography in 115 cases. The accuracy of arterial portography was confirmed in 21 cases where orthotopic liver transplantation was performed and used as a 'bench-mark' against which to assess the ultrasound findings. Ultrasound correctly assessed portal vein patency in 87.5% of patients. It was more accurate in assessing patency (90%) than occlusion (68%). Ultrasound correctly assessed portal vein patency in 90% of cases of cirrhosis and hepatic malignancy. Difficulties occurred in children with biliary atresia particularly following the Kasai operation (37.5% accuracy). In the absence of previous surgery to the portal vein or biliary system, ultrasound is comparable to arterial portography and can be used as the sole means of assessment.
通过将超声评估门静脉通畅性的结果与115例动脉门静脉造影的结果进行比较，确定了超声评估的准确性。在21例行原位肝移植的病例中，动脉门静脉造影的准确性得到了证实，并被用作评估超声检查结果的“基准”。超声正确评估了87.5%患者的门静脉通畅性。在评估通畅性（90%）方面比评估闭塞（68%）更准确。超声在90%的肝硬化和肝恶性肿瘤病例中正确评估了门静脉通畅性。患有胆道闭锁的儿童，尤其是在进行葛西手术后，评估存在困难（准确性为37.5%）。在没有门静脉或胆道系统既往手术史的情况下，超声与动脉门静脉造影相当，可作为唯一的评估手段。
