Artificial graft replacement for the pulmonary artery aneurysm: three case reports

Abstract Pulmonary artery aneurysm (PAA) is a relatively rare disease. The symptoms are usually non-specific and often identified due to coughing or dyspnea. Pericardial tamponade caused by the PAA dissection or rupture is the most common cause of death, so active surgical treatment is recommended. The surgical reports in the literature are handful. Here we report three cases, all of whom were admitted due to exertional dyspnea. The PAA were observed from the main to the left and/or the right pulmonary artery. All three cases received PAA resection and artificial graft replacement with good outcomes.
