폐동맥 카테터가 하대정맥에서 U자 고리를 형성한 증례 1례

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.
