We report on two cases of low-birth-weight preterm infants with patent ductus venosus associated with hepatic hypoechoic lesions of the fourth segment in an otherwise normal liver. Although tumorlike hepatic lesions have been previously reported in association with portosystemic shunts in children and adults, they were never described in preterm infants during physiological patency of ductus venosus. In our patients, hepatic lesions disappeared shortly after the spontaneous ductus closure. Physiopathologic interactions are discussed regarding altered portal blood supply caused by ductus venosus shunt.
我们报告了两例低出生体重早产儿，他们的脐静脉导管持续开放，且伴有第四段肝回声减弱。尽管此前曾有报道称，在儿童和成人的门体分流中存在类似肿瘤的肝病变，但在生理性脐静脉导管开放的早产儿中从未有过相关描述。在我们的患者中，肝病变在脐静脉导管自然闭合后不久即消失。我们讨论了由于脐静脉分流引起的门静脉血液供应改变所导致的病理生理相互作用。
