目的：总结肺动脉吊带（PAS）的多层螺旋CT（MSCT）表现，评价MSCT在PAS术前评估中的应用价值。方法：回顾性分析14例PAS患者的临床及影像资料，对支气管形态及狭窄程度、范围进行分型。结果：14例患者均为完全型PAS，MSCT对PAS的诊断率为100%，其中ⅠA型3例，ⅡA型6例，ⅡB型5例；气道轻度狭窄6例，重度狭窄7例，短段狭窄6例，长段狭窄7例；14例患者中有7例伴有其他先天性心血管异常。结论：MSCT可早期明确诊断PAS及并发心脏畸形，评价气管狭窄的程度、范围，对PAS术前评估具有较高的应用价值。
Abstract
Objective: To summarize the MSCT findings of PAS and evaluate the value of MSCT in preoperative evaluation of PAS. Methods: The clinical and imaging data of 14 patients with PAS were analyzed retrospectively. Bronchial morphology and stenosis were classified. Results: Fourteen patients were all complete PAS. The diagnostic rate of MSCT for PAS was 100%, including 3 cases of type ⅠA, 6 cases of type ⅡA, 5 cases of type ⅡB. There were 6 cases of mild stenosis, 7 cases of severe stenosis, 6 cases of short segment stenosis, and 7 cases of long segment stenosis. Seven of the 14 patients had other congenital cardiovascular abnormalities. Conclusion: MSCT plays an important role in the early diagnosis of PAS. At the same time, MSCT can clearly diagnose the PAS related complications and display the extent and scope of tracheal stenosis. It has a high application value for preoperative evaluation of PAS.
