The use of Swan-Ganz catheters has increased tremendously since
they were first introduced in 1970. Their ability to give vital
hemodynamic measurements in critically ill patients makes their use
invaluable when providing quality medical care. The formation of
pulmonary artery (PA) pseudoaneurysm from a Swan-Ganz catheter-induced
perforation of the PA is a rare but potentially fatal complication of
Swan-Ganz catheter use. Three case presentations and a review of the
literature are presented.
