Study Objectives:
To determine the outcome of patients with pulmonary catheter-induced pulmonary artery pseudoansurysms (PSAs) treated with embolization.
Design:
Retrospective outcomes review.
Setting:
Large urban tertiary-care hospital.
Patients:
All patients who presented to diagnostic angiography for ruptured pulmonary artery PSA caused by pulmonary artery catheters (PACs) from November 1990 to September 1995. A total of six patients were examined.
Interventions:
Transcatheter embolotherapy with coils, absorbable gelatin sponges (Gelfoam), and suture material.
Results:
These procedures were technically successful in all patients, and none had recurrent hemoptysis. Four of the six patients were discharged from the hospital.
Conclusion:
Embolotherapy is a useful alternative to surgery for some patients with PAC-induced pulmonary PSA.
