Sarcoma of the main pulmonary artery: an unusual etiology for recurrent pulmonary emboli.
We describe a case of primary pulmonary artery (PA) trunk spindle cell sarcoma in an 86 year old female presenting clinically with debilitating signs of recurrent pulmonary embolism. Further extensive work aroused suspicion for pulmonary artery malignancy. Palliative wide surgical resection, pulmonary artery tumor embolectomy and reconstruction of the proximal pulmonary artery and right ventricle outflow tract (RVOT) with bovine pericardial tissue were performed. She survived the procedure with an improved quality of life, but expired due to recurrence at 6 months postoperatively. Albeit uncommon, pulmonary artery sarcoma is nowadays a more frequently preoperatively diagnosed and surgically treated malignancy. With a modern low perioperative mortality, aggressive surgical resection remains as the single most effective modality for its treatment and can result in short term palliation in selected patients.
