Using an expanded polytetrafluoroethylene conduit, a subclavian artery-to-pulmonary artery shunt was created in an infant with tetralogy of Fallot. The postoperative course was complicated by sepsis, shunt occlusion, and pneumonia. Four years later, an obstructive mass was found in the right main bronchus on fluoroscopy and was retrieved on rigid endoscopy, which turned out to be the migrated conduit. This case implies that a vascular conduit anastomosed to a systemic artery can migrate into the airway without bleeding, pseudoaneurysm formation, or host artery occlusion.
在一名法洛四联症婴儿中，使用一段扩张的聚四氟乙烯导管建立了锁骨下动脉至肺动脉分流术。术后病程因败血症、分流闭塞和肺炎而复杂化。四年后，在荧光透视检查中发现右主支气管有一个阻塞性肿块，并通过硬质内镜取出，结果发现是移位的导管。该病例表明，与体动脉吻合的血管导管可迁移至气道，而不会发生出血、假性动脉瘤形成或宿主动脉闭塞。
