The Current Role of the Pulmonary Artery Catheter in Critical Care: A Case Report and Review of the Literature:

The clinical use of the pulmonary artery catheter (PAC) has changed the modern practice of intensive care medicine. However, the effect of invasive haemodynamic monitoring on patient outcome remains uncertain. We report an unusual case of malposition of a PAC in the left internal mammary vein and we discuss the role of this monitor in the intensive care setting. Overall, the literature does not suggest a positive effect of PAC use on patient outcome. It has been suggested that PAC insertion may be of little benefit unless linked to specific therapies which may alter outcome. It is essential to understand the capabilities and limitations of the PAC in order to minimise potential complications and maximise benefits.
