Massive thrombosis associated with use of the Swan-Ganz catheter.

A patient with severe respiratory failure due to overwhelming pneumonia was monitored with a Swan-Ganz catheter. Postmortem examination revealed massive antemortem thrombosis surrounding the Swan-Ganz catheter tip. The presence of the thrombus about the catheter tip was not suspected before death, but retrospective analysis of a variety of parameters suggested massive pulmonary vascular obstruction.
