Three cases are presented dealing with rare lethal complications during the insertion of pulmonary artery catheters (PAC). Complications resulting from catheter insertion have been reported on numerous occasions; we report further examples of inadequate insertion techniques. ⋯ Based on our observations, we believe the low complication rate associated with PAC insertion has led to deviations from the normal guidelines by some physicians. Despite adequate precautions and insertion technique, iatrogenic lesions cannot be avoided in all cases because of pre-existing risk factors. For the evaluation of catheter-induced complications and the development of a risk profile, more autopsies as well as more detailed clinical documentation would be necessary.
