Right Pulmonary Artery Bypass After Prior Left Pneumonectomy for Pulmonary Artery Sarcoma

Primary pulmonary artery sarcoma is a rare and aggressive malignant neoplasm with poor prognosis and frequent local recurrence. Complete resection remains the treatment of choice, but repeated surgery is rarely described, especially after a pneumonectomy. Repeated radical resection of recurrent pulmonary artery sarcoma with prosthetic reconstruction is feasible and can be performed without additional lung loss. Three-dimensional modeling is a valuable adjunct for preoperative planning in complex pulmonary vascular surgery and may help preserve pulmonary function in selected patients.
