Pulmonary arteriovenous malformation can occur in up to 25% of patients after a classic Glenn shunt. Although unproven, exclusion of hepatic venous blood from the lungs has been proposed as a possible cause. We present a patient born with anomalous hepatic venous drainage into the left atrium with an intact atrial septum in whom pulmonary arteriovenous malformation developed in childhood. This was reversed after diversion of the hepatic venous drainage to the right atrium, supporting exclusion of hepatic venous flow as the cause of pulmonary arteriovenous malformation. The association with the hepatopulmonary syndrome is discussed.
在经典格林分流术后，高达25%的患者可能发生肺动静脉畸形。虽然未经证实，但有人提出将肝静脉血排除在肺外可能是一个原因。我们报告一名出生时肝静脉异常引流至左心房且房间隔完整的患者，其在儿童期发生了肺动静脉畸形。在将肝静脉引流改道至右心房后，这种情况得到了逆转，这支持将肝静脉血流排除为肺动静脉畸形的病因。本文还讨论了其与肝肺综合征的关联。
