Nonsurgical extraction of intracardiac double-knotted pulmonary artery catheter

A 75-year-old patient was admitted to the operating room for an emergency laparotomy for leaking abdominal aortic aneurysm. A pulmonary artery catheter (PAC) was inserted through the right internal jugular vein but it was impossible to advance the catheter lip into the pulmonary artery. We tried to withdraw the catheter but this was also impossible. A postoperative chest radiograph revealed a catheter knot in the right atrium. We succeeded in removing the PAC through a 14-French sheath introducer placed in the femoral vein via fluoroscopy.
