In rare instances in congenital cardiac surgery, ≥1 of the hepatic veins may end up incorporated either intentionally or inadvertently with the pulmonary venous atrium (oxygenated blood) while the remainder of the hepatic veins are left to drain normally with the systemic venous blood (less oxygenated blood). What happens when this is done? As it turns out, hepatic venous connections end up forming between the lobes of the liver, and a significant shunt results. The direction of shunting, however, depends on the physiology. We present 2 cases in which a single hepatic vein was left connected to the pulmonary venous atrium and produced very different hemodynamic consequences.
在先天性心脏手术的罕见情况下，≥1条肝静脉最终可能会有意或无意地与肺静脉心房（含氧血）合并，而其余肝静脉则正常引流体循环静脉血（含氧量较低的血）。这样做会发生什么呢？结果是，肝静脉连接最终在肝叶之间形成，导致显著的分流。然而，分流的方向取决于生理情况。我们展示2例病例，其中单条肝静脉与肺静脉心房相连，产生了非常不同的血流动力学后果。
