中文摘要:
      目的 探讨交叉肺动脉患儿的临床及CT特点。方法 回顾性分析17例交叉肺动脉患儿的临床及CT检查资料,记录合并心血管畸形、气道畸形、肺炎及其他临床合并症情况。结果 心胸CT三维重建图像可清晰显示交叉肺动脉及其合并心血管畸形、气道畸形、肺炎。其中合并房间隔缺损9例,室间隔缺损9例,主动脉右弓右降9例,动脉导管未闭5例,迷走左或右锁骨下动脉4例,主动脉缩窄3例,法洛四联症3例,主肺动脉间隔缺损2例,部分型肺静脉异位引流2例,左肺动脉狭窄1例,主动脉瓣狭窄1例,主动脉瓣二叶畸形1例,永存动脉干1例,右心室双出口1例,主动脉离断1例,肺动脉闭锁1例,冠状动脉起源异常1例,主动脉左弓右降1例,永存左上腔静脉1例,心肌致密化不全1例。10例合并肺炎,其中2例有支气管狭窄。其他临床合并症包括18-三体综合征、顽固性低钙血症、癫痫各1例。结论 交叉肺动脉是一种罕见的先天性心脏病,常伴其他心脏、大血管发育异常,且多合并肺炎。CT三维重建图像可直观、清晰显示交叉肺动脉及其合并心血管解剖异常,同时显示肺内、气道异常及其与大血管的立体关系。
英文摘要:
      Objective To investigate the clinical characteristics and CT manifestations of crossed pulmonary arteries in children. Methods The clinical and cardiac CT data of 17 children patients with crossed pulmonary arteries were retrospectively analyzed. The complicated cardiovascular malformations, airway abnormalities, pneumonia and other special clinical conditions were reported. Results The crossed pulmonary arteries, cardiovascular malformations, airway abnormalities and pneumonia were detected accurately by cardiac CT three-dimensional reconstruction imaging. The complicated malformations include atrial septal defect in 9 cases, ventricular septal defect in 9 cases, right aortic arch with right descending in 9 cases, arterial duct arteriosus in 5 cases, the aberrant left or right subclavian artery origin anomalies in 4 cases, aortic coarctation in 3 cases, tetralogy of Fallot in 3 cases, pulmonary arterial septal defect in 2 cases, anomalous pulmonary venous drainage in 2 cases, left pulmonary artery stenosis in 1 case, aortic valve stenosis in 1 case, aortic bicuspid leaf malformation in 1 case, persistent truncus arteriosus in 1 case, right ventricular double outlet in 1 case, aortic transection in 1 case, pulmonary artery atresia in 1 case, coronary artery origin anomalies in 1 case, aortic arch on the left and right down 1 case, persistent left superior vena cava in 1 case and myocardial insufficiency in 1 case. There were 10 cases complicated with pneumonia, 2 cases of them with bronchial stenosis. Other clinical complications included 1 case of trisomy 18 syndrome, refractory epilepsy and hypocalcemia respectively. Conclusion Crossed pulmonary arteries is a rare congenital heart disease and complicates with other cardiovascular malformations commonly. Pneumonia is the most common complication. Cardiac CT three-dimensional reconstruction imaging has advantage in displaying the relationships of the crossed pulmonary arteries, cardiovascular malformations and airway abnormalities.
