Show Summary Details



The occurrence of pulmonary artery aneurysm (PAA) is extremely rare in the clinical setting. Careful treatment should be considered because of the possibility of fatal complications including rupture, dissection, pulmonary embolism and heart failure. Our goal is to contribute a better understanding of this disease and its treatment.


Information on patients diagnosed with PAA was retrieved from the institute's database. The detailed data including aetiology, clinical presentation, diagnostic methods, operation methods and long-term outcomes of the surgical cases were outlined and analysed.


In total, 21 patients were diagnosed with PAA in Peking Union Medical College Hospital from 1980 to 2015, among whom 5 patients received surgical treatment, including 2 patients with giant PAAs. The complete remission rate of surgical cases was 80%, and the average postoperative hospital stay was 8.5 ± 1.29 days. One postoperative death occurred due to distributive shock.


PAAs must be seriously classified by aetiology to be treated appropriately. Patients with giant-size PAAs, and those with pulmonary hypertension, anatomical anomalies, and rapid growth and compression of neighbouring critical structures, are proper candidates for surgery. Surgical options include aneurysm repair and replacement with allogeneic/synthetic grafts, depending on the situation. Additionally, the correction of associated abnormalities should be performed simultaneously during surgery. Surgical outcomes are effective, and long-term prognoses are satisfactory.
