Bilateral bidirectional Glenn shunts are associated with the risk of developing pulmonary artery bifurcation stenosis, resulting in variable pulmonary blood flow to either lung. This could negatively impact the subsequent stages of the single ventricle palliation pathway. This report highlights the value of 4D flow sequence from the cardiac magnetic resonance imaging in demonstrating the pulmonary blood flow characteristics following a bilateral bidirectional Glenn procedure. Mapping the blood flow pattern and its quantification to each lung provide objective insights into the possible predisposing factors for the development of pulmonary bifurcation stenosis.
双侧双向格林分流术与发生肺动脉分叉狭窄的风险相关，导致双肺的肺血流量可变。这可能会对单心室姑息治疗路径的后续阶段产生负面影响。本报告强调了心脏磁共振成像的4D血流序列在显示双侧双向格林手术后肺血流特征方面的价值。绘制血流模式并对每侧肺进行血流定量分析，可为肺动脉分叉狭窄发生的可能诱发因素提供客观见解。
