2例Abernethy畸形的诊断分析 Diagnosis of Abernethy Malformation in 2 Cases

目的：探讨Abernethy畸形的诊断方法。方法：回顾2005年至2012年共计2例Abernethy畸形患者的诊治情况，并对其进行分析。结果：Abernethy畸形临床表现及体征缺乏特异性，超声检查可以有效的发现门静脉闭锁的情况；CTA、MRA及DSA造影可以对Abernethy畸形进行准确诊断及分型，并可全面评估患者腹腔静脉血管畸形情况。结论：腹部超声检查有助于Abernethy综合征的早期筛查；CTA、MRA及DSA造影均可以作为Abernethy畸形的最佳确诊及分型方法. Objective: To explore methods for diagnosis ofAbernethy malformation. Methods: 2 cases of Abernethy malformation were collected from 2005 to 2012 and analyzed. Results: Symptoms and signs in patients of Abernethy malformation were lack of specificity. Ultra-sound examination could be used to detect the atresia of portal vein. CTA, MRA and DSA could be accurately used to diagnose and classify Abernethy malformation, which could also be used to estimate the whole malformation of abdominal arteries and veins. Conclusion:Abdominal ultra-sound examination could be a very good screening method for Abernethy malformation’s diagnosis; CTA, MRA and DSA could be used to accurately diagnosis and classify Abernethy malformation.
