PURPOSE
To analyze the correlation between pseudolesions seen in segment IV of the liver and aberrant gastric venous drainage (AGVD).
MATERIALS AND METHODS
Twenty-two patients with a pseudolesion in the posterior edge of segment IV of the liver (group A) and 100 randomly selected patients without pseudolesions (group B) underwent computed tomography during arterial portography (CTAP) and hepatic arteriography. The frequency of the visualization of AGVD to segment IV was compared for groups A and B.
RESULTS
AGVD was seen at arteriography in 18 of 22 patients in group A. None of the patients in group B had AGVD. The difference in the frequency of angiographically visible AGVD was statistically significant (chi 2 test, P < .01).
CONCLUSION
AGVD is the main cause of pseudolesions in the posterior edge of segment IV of the liver.
目的
分析肝脏IV段假性病变与胃静脉异常引流（AGVD）之间的相关性。
材料与方法
22例肝脏IV段后缘有假性病变的患者（A组）和100例随机选取的无假性病变的患者（B组）接受了动脉门静脉造影计算机断层扫描（CTAP）和肝动脉造影。比较A组和B组中AGVD在IV段的显影频率。
结果
A组22例患者中有18例在动脉造影时可见AGVD。B组患者均无AGVD。血管造影可见AGVD的频率差异具有统计学意义（卡方检验，P <.01）。
结论
AGVD是肝脏IV段后缘假性病变的主要原因。
