[Pulmonary artery pseudoaneurysm caused by a Swan-Ganz catheter and treated by embolization]. / Pseudoanévrisme artériel pulmonaire post-cathéter de Swan-Ganz traité par embolisation.

ABSTRACT

The frequency of life-threatening complications induced by Swan-Ganz catheter is estimated at 2% to 17%. Pseudoaneurysm formation secondary to traumatic injury of the pulmonary artery is rare (0.66% to 2%), but carries a high risk of hemorrhagie. Recognition of possible lesions should be based on clinical data and predisposing factors. Diagnostic and therapeutic investigations should be rapidly performed. Embolization is the best treatment giving very good results. Should acute hemorrhage occur in the operating room, emergency vascular occlusion can be carried out by the use of the Swan-Ganz catheter.
