Bidirectional superior cavopulmonary shunt (bidirectional Glenn shunt) is generally performed in many congenital cardiac anomalies where complete two ventricle circulations cannot be easily achieved. The advantages of BDG shunt are achieved by partially separating the pulmonary and systemic venous circuits, and include reduced ventricular preload and long-term preservation of myocardium. The benefits of additional pulsatile pulmonary blood flow include the potential growth of pulmonary arteries, possible improvement in arterial oxygen saturation, and possible prevention of development of pulmonary arteriovenous malformations. However, increase in the systemic venous pressure after BDG with additional pulsatile blood flow is known. We describe the peri-operative implications of severe flow reversal in the superior vena cava after pulsatile BDG shunt construction in a child who presented for surgical interruption of the main pulmonary artery.
双向腔肺分流术（双向格林分流术）通常用于许多难以轻易实现完全双心室循环的先天性心脏畸形。BDG分流术的优势在于部分分离肺静脉和体静脉循环，包括降低心室前负荷和长期保护心肌。额外的搏动性肺血流的益处包括肺动脉的潜在生长、动脉血氧饱和度可能改善以及可能预防肺动静脉畸形的发展。然而，已知在BDG术后增加搏动性血流会导致体静脉压力升高。我们描述了一名因手术中断主肺动脉而接受搏动性BDG分流术构建的儿童，术后上腔静脉严重血流逆转的围手术期影响。
