摘要
目的:评价MSCT在左肺动脉吊带(LPAS)诊断中的应用价值。方法:回顾性分析7例经手术证实的LPAS的临床表现及MSCT特征。结果:7例LPAS术前MSCT均正确诊断,7例均合并心内、外畸形。MSCT及后处理(MPR、MIP、MinIP、VR)示:7例中完全性LPAS 6例,表现为左肺动脉自右主肺动脉发出,从右主支气管上方绕行并向后走行至气管和食管间达左肺门;部分性LPAS 1例,表现为左上肺动脉起自右主肺动脉,从右主支气管上方穿过,向后走行于气管和食管之间并供血左肺上叶,而左下肺动脉起源和走行正常;7例均伴不同程度的气管和/或支气管狭窄。结论:MSCT不仅能显示LPAS及其合并心血管畸形,还能显示LPAS伴随气管、支气管狭窄,对制定外科手术方案具有重要临床价值。
Objective： To evaluate the clinical value of multi-slice spiral CT （MSCT） in diagnosis of left pulmonary ar- tery sling （I.PAS）. Methods： MSCT findings and clinical manifestations of 7 patients with I.PAS, which were confirmed by surgery,were analyzed retrospectively. Results： All 7 cases of I.PAS were complicated with cardiac malformation and were correctly diagnosed by MSCT. 6 of the 7 cases were complete left pulmonary artery sling, the other one was partial left pul- monary artery sling. All cases had congenital cardiac malformations and various degrees of tracheal or/and bronchi^d steno- sis. Conclusions.. MSCT is an ideal imaging modality for identifying LPAS and associated tracheobronchial anomalies. It can provide useful information for surgical planning.
