Transcatheter coil embolization of large pulmonary artery pseudoaneurysms in a child

The authors report a case of a 5-year-old boy who initially presented with mastoiditis, underwent successful surgical treatment, and during the immediate postoperative period developed multiple, bilateral pulmonary artery pseudoaneurysms. The large size and multiplicity of the pseudoaneurysms precluded the patient from undergoing thoracic surgery. Successful endovascular coil and wire embolization was performed in a staged set of procedures with use of more than 30 m of wire and coils.
