Interruption of Left Pulmonary Artery with Atrial Septal Defect and Right Side Aortic Arch: A Case Report Diagnosed with MRA

左側肺動脈中斷合併心房中隔缺損及右側主動脈弓:以磁振血管造影診斷之病例報告

摘要


肺主動脈是在胎兒時期時由第六對主動脈弓衍生而來。從右側或左側肺動脈近端中斷是罕見的先天異常,而且可能會合併其他的心血管異常。我們報告一位四十八歲的男性病人,具有左側肺動脈中斷合併心房中隔缺損及右側主動脈弓。磁振造影則相當有助於診斷肺動脈中斷、側枝循環、以及相關心血管異常。

並列摘要


The main pulmonary arteries are derived from the sixth aortic arch during intrauterine development. Proximal interruption of the right or left pulmonary artery is a rare anomaly, which may be accompanied by cardiovascular anomalies. We describe a 48-year-old man with interruption of left pulmonary artery with atrial septal defect and right side aortic arch. MRI is helpful in identifying the interruption of pulmonary artery, the collateral circulation, and the associated cardiovascular anomalies.
