[A case of iatrogenic pseudoaneurysm of the pulmonary artery induced by a Swan-Ganz catheter].
We report a case of iatrogenic pseudoaneurysm of the right pulmonary artery induced by a Swan-Ganz (SG) catheter. An SG catheter was inserted to the pulmonary artery before the esophageal surgery. Chest radiograph after the surgery showed a nodule in the right lower lung field. Based on the retrospective review of serial chest radiographies after SG catheter placement, we suspected iatrogenic pseudoaneurysm of the pulmonary artery caused by over-insertion of the catheter tip. Contrast-enhanced CT showed the nodular shadow with eccentric and marked enhancement continuing right A4b. We diagnosed a pseudoaneurysm of the pulmonary artery. The nodular shadow resolved spontaneously over a 2-month period.
