Valved conduits are frequently used in congenital heart surgery to establish continuity between the right ventricle and the pulmonary arteries. The Contegra bovine jugular vein (Medtronic Inc, Minneapolis, MN) is a conduit that incorporates a tri-leaflet valve and affords off-the-shelf availability, good handling characteristics, and excellent hemodynamics. However, complications related to the use of this device have been reported, with conduit failure occurring mainly as a consequence of stenosis, conduit thrombosis, and valve regurgitation. We present a case of aneurysmal conduit failure of a 14-mm Contegra conduit used to reconstruct the right ventricular outflow tract.
带瓣管道常用于先天性心脏病手术，以建立右心室与肺动脉之间的连接。康蒂格拉（Contegra）牛颈静脉管道（美敦力公司，明尼阿波利斯，明尼苏达州）是一种包含三叶瓣膜的管道，具有现货供应、良好的操作特性和出色的血流动力学性能。然而，已有使用该装置相关并发症的报道，管道故障主要表现为狭窄、管道血栓形成和瓣膜反流。我们报告一例使用14毫米康蒂格拉管道重建右心室流出道时发生的动脉瘤样管道故障病例。
