Paget-Schroetter syndrome in a teenager after throwing firecrackers - A case report.

Paget-Schroetter syndrome (PSS), or effort thrombosis, refers to axillary and/or subclavian vein thrombosis associated with repetitive effort of the superior limbs, and is rare in the pediatric population. We report the case of a previously healthy 15-year-old boy who presented with a painful and swollen right arm after throwing firecrackers. Doppler ultrasound showed extensive right subclavian and axillary vein thrombosis. Anticoagulation therapy was started and had favorable evolution. We emphasize that PSS must be included in the differential diagnosis of a swollen arm.
