Key result
Surgical resection of a pulmonary artery sarcoma in the right ventricular outflow tract improved hemodynamics, though local recurrence was detected approximately two months after surgery.
Why the study?
PAS is a sporadic malignant tumor that can involve the RVOT and lead to obstruction, syncope, or sudden death, where early diagnosis and surgical resection are essential.

Surgery may yield short-term hemodynamic gains in pulmonary artery sarcoma; leaves open durable control strategies amid early recurrence.
Pulmonary artery sarcoma (PAS) is a sporadic malignant tumor that mainly originates from the pulmonary arteries. However, PAS may also involve the right ventricular outflow tract (RVOT) and lead to obstruction, syncope, or sudden death. Early diagnosis and complete surgical resection are essential to prolong survival and improve the quality of life of patients with PAS. Herein, we report a case of a young female patient admitted for pulmonary malignancy and acute pulmonary embolism. The patient had a mass in the RVOT, which was detected by transthoracic echocardiography. Computed tomography and magnetic resonance imaging revealed the invasion depth and extent of the lesions. Surgical resection improved hemodynamics, while pathological and immunohistochemical tests confirmed the diagnosis of a pulmonary artery sarcoma. Local recurrence was detected in the adjacent tissues about two months after the surgery. Given the potential risk of reoperation, the patient was suggested to undergo conservative treatment.
