Abstract

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.

摘要

双侧双向Glenn分流与发展肺动脉分叉狭窄的风险相关。导致肺血流量变化到任一肺。这可能会负面影响单心室缓解途径的后续阶段。该报告强调了心脏磁共振成像的4D流序列在证明双侧双向Glenn手术后的肺血流特征方面的价值。将血流模式及其量化映射到每个肺，可以客观地了解肺分叉狭窄发展的可能诱发因素。
