Perforation of a pulmonary artery after placement of a Swan-Ganz catheter is a serious complication that requires immediate management. Exact description of size and anatomic localization of a pulmonary pseudoaneurysm is crucial for planning further therapy. This report describes a patient who experienced such a complication, but in whom primary pulmonary angiography failed to demonstrate bleeding. However, multislice computed tomography not only correctly demonstrated the anatomic location of the pseudoaneurysm but was also able to directly visualize the feeder vessel and its connection to the aneurysm. This information was essential for subsequent superselective angiographic visualization of the feeder vessel and for successful embolization as the least invasive method of choice.
放置Swan-Ganz导管后肺动脉穿孔是一种严重并发症，需要立即处理。准确描述肺假性动脉瘤的大小和解剖定位对于规划进一步治疗至关重要。本报告描述了一名发生此类并发症的患者，但初次肺血管造影未能显示出血情况。然而，多层计算机断层扫描不仅正确显示了假性动脉瘤的解剖位置，还能够直接观察到供血血管及其与动脉瘤的连接。这些信息对于随后对供血血管进行超选择性血管造影以及作为首选的微创方法成功进行栓塞至关重要。
