Reconstruction of a Giant Main Pulmonary Artery Aneurysm Using a Porcine Root in an Adult Patient

Pulmonary artery aneurysm (PAA) is a rare disorder with a difficult diagnosis and debated management in literature due to the limited number of cases. Even if the definitive treatment of PAA is surgery, consistent guidelines still need to be developed to help surgeons determine when intervention is appropriate. We report a case of a 77-year-old female diagnosed with central PAA measuring 61 mm at contrast-enhanced computerized tomography scan which was treated surgically. The patient underwent a successful elective complete pulmonary root replacement with a Medtronic Freestyle (Medtronic Inc, Minneapolis, MN) porcine root. Postprocedural recovery and follow-up at 12 months were uneventful.
