Congenital extrahepatic portosystemic shunt (CEPS) is a rare disorder characterised by partial or complete diversion of portomesenteric blood into systemic veins via congenital shunts. Type I is characterised by complete lack of intrahepatic portal venous blood flow due to an end to side fistula between main portal vein and the inferior vena cava. Type II on the other hand is characterised by partial preservation of portal blood supply to liver and side to side fistula between main portal vein or its branches and mesenteric, splenic, gastric, and systemic veins. The presentation of these patients is variable. Focal liver lesions, most commonly nodular regenerative hyperplasia, are an important clue to the underlying condition. This pictorial essay covers imaging characteristics in abdominopelvic region.
先天性肝外门体分流(CEPS)是一种罕见的疾病,其特征是门静脉肠系膜血液通过先天性分流部分或完全分流至体静脉。I型的特征是由于门静脉主干与下腔静脉之间的端侧瘘导致肝内门静脉血流完全缺失。另一方面,II型的特征是肝脏的门静脉血供部分保留,且门静脉主干或其分支与肠系膜静脉、脾静脉、胃静脉和体静脉之间存在侧侧瘘。这些患者的临床表现各异。局灶性肝病变,最常见的是结节性再生性增生,是潜在病情的重要线索。这篇图文并茂的文章涵盖了腹盆腔区域的影像学特征。
