Abstract
Pulmanary artery catheter is a useful monitoring device for the pulmonary artery pressure; pulmonary artery wedge pressure; cardiac output; and mixed venous oxygen saturation in the cardiac surgery or intensive care. However the insertion procedure brings about many complications including arrhythmia; pulmonary artery rupture; thrombosis; knotting; and entrapment. We report here on a case of fixing of the pulmonary artery catheter in the pulmonary artery lumen; which causes failure for obtaining pulmonary artery wedge pressure and misplacement and U-shape looping in the inferior vena cava in the patient underwent mitral valve replacement. The looping was corrected by simple retraction of the catheter without surgical intervention.
Key Words: Complications, Misplacement, Pulmonary artery catheter
