Although the etiology of pulmonary fistulas in congenital heart disease remains unknown, several hemodynamic factors are thought to play a role. Recently it was postulated that hepatic venous effluent might protect the pulmonary bed from development of pulmonary fistulas. However, there are no experimental data supporting this hypothesis. Here, we present the cases of 2 patients in whom pulmonary fistulas developed after unintentional surgical exclusion of the hepatic venous flow from the pulmonary circulation. In both patients, symptoms resolved after rerouting of the hepatic venous blood to the lungs.
虽然先天性心脏病中肺瘘的病因尚不清楚，但一些血流动力学因素被认为起了作用。最近有人推测肝静脉流出物可能保护肺床免于发生肺瘘。然而，尚无实验数据支持这一假说。在此，我们报告2例患者的病例，这2例患者在无意中手术排除了肝静脉血流进入肺循环后发生了肺瘘。在这2例患者中，将肝静脉血改道回流至肺后症状均得到缓解。
