摘要
目的评价计算机断层成像(CT)动脉造影诊断肺动脉起源异常的临床价值。方法对经CT动脉造影诊断肺动脉起源异常的9例患者进行回顾性分析,其中男6例,女3例;年龄0.2~33岁,年龄中位数2.8岁。复习相关的文献资料,进一步与超声心动图结果对照。CT动脉造影检查采用连续容积扫描。结果 9例患者均经CT动脉造影诊断,其中8例为右肺动脉起源异常,1例为左肺动脉起源异常,均起自升主动脉。其中5例合并动脉导管未闭,3例合并室间隔缺损,1例合并主肺动脉间隔缺损,1例合并肺动脉瓣狭窄,1例为单发畸形。结论 CT动脉造影在对肺动脉起源异常诊断中有较高的诊断价值,可以替代心血管造影等有创检查。
Objective To evaluate the clinical value of computer tomography angiography(CTA) in the diagnosis of anomalous pulmonary artery. Methods Clinical data of 9 patients with anomalous pulmonary artery diagnosed by CTA were retrospectively analyzed, and CTA results were compared with those of echocardiographic examination. Results CTA clearly demonstrated the origin sites and topography of anomalous pulmonary arteries in all 9 patients. One patients presented with left pulmonary artery sling, and 8 patients presented with anomalous right pulmonary artery which originated from the proximal ascending aorta. Among them 1 patient was with isolated anomalous origin of right pulmonary, and the others were complicated with patent ductus artery ( 5 cases ), ventricular septal defect ( 3 cases ), and aortopulmonary septal defect ( 1 case), etc. Conclusions CTA is highly valuable in the diagnosis of anomalous origin of pulmonary artery and associated abnormities by clearly developing the pathologic anatomic features and complicated cardiovascular malformations.
