中文摘要 | 單側肺動脈缺失是一個罕見的肺血管異常,它通常合併其他心臓結構異常。我們報告一病例爲九歲女性診斷爲單獨的左側肺動脈缺失併右主動脈弓,此外這病例並無合併其他心臓結構異常。一系列影像檢查包括:胸部X光、食道X光攝影、心臓超音波、胸部斷層掃描、通氣及灌流掃描、心導管血攝影、三度空間核 磁共振血管攝影。由一張左右肺不對稱的胸部X光,開啟一連串後續檢查。心導管及肺動脈血管攝影診斷爲左側且動脈缺失,核磁共振血管攝影是一有效的非侵襲性檢查,它確定地證明左肺動脈缺失且無陷藏的且動脈。因此手術建立部血流連續是不可能的。 |
英文摘要 | Unilateral absence of a pulmonary artery (UAPA) is a rare pulmonary vascular anomaly that is usually associated with other cardiac anomalies. We report a 9-year-old female diagnosed with isolated unilateral absence of the left pulmonary artery and a right aortic arch but without other cardiac anomalies. The only symptoms the patient had were recurrent respiratory tract infections. The chest x-rays showed asymmetric lung fields, prompting subsequent studies. A series of imaging studies including chest x-rays, esophagography, echocardiography, chest computed tomography, lung ventilation-perfusion scintigraphy, angiocardiography, and 3-dimensional magnetic resonance angiography (3D-MRA) were done. The diagnosis was confirmed by the cardiac catheterization and pulmonary angiography, which disclosed absence of the left pulmonary artery. 3D-MRA conclusively demonstrated total absence of the left pulmonary artery without an occult left pulmonary artery or systemic-to-pulmonary collateral arteries. Therefore, surgical re-establishment of pulmonary continuity was impossible. |
