A ventilation-perfusion (V/Q) lung scan in a postoperative patient with a Swan-Ganz catheter showed an area of mismatch suggesting pulmonary embolism. Radiographs, as well as failure to get a venous return from the catheter suggested wedging. A pulmonary angiogram, performed after the Swan-Ganz catheter was pulled back, was essentially normal. An autopsy performed within 24 hours of the lung scan did not reveal pulmonary emboli. Wedged Swan-Ganz catheter was probably responsible for the V/Q mismatch.
一名术后留置 Swan-Ganz 导管的患者进行通气-灌注（V/Q）肺扫描，结果显示存在不匹配区域，提示肺栓塞。X 光片以及导管无法获得静脉回血提示导管楔入。在 Swan-Ganz 导管回撤后进行的肺动脉造影基本正常。在肺扫描后 24 小时内进行的尸检未发现肺栓塞。楔入的 Swan-Ganz 导管可能是导致 V/Q 不匹配的原因。
