Acute Pulmonary Embolism due to Paget-Schroetter Syndrome.

A 17-year-old Japanese male athlete presented to the emergency department at our hospital with a chief complaint of exertional dyspnea. Although there were no significant findings in the right and left upper extremities on a physical examination, a chest computed tomography scan showed bilateral multiple thrombosis in the pulmonary arteries, indicating pulmonary thromboembolism, and deep vein thrombosis in the left subclavian vein. Upper limb venography showed interruption of the left subclavian vein (so-called Paget-Schroetter syndrome; PSS). We herein report this rare case of PSS that led to pulmonary thromboembolism in a young, male field athlete.
