[Upper extremity deep vein thrombosis following soft tissue trauma].

A 27-year-old man sustained soft tissue injury to the left shoulder following a fall. Three days later, a diagnosis of left proximal subclavian vein thrombosis was made. The patient was given intravenous urokinase for 24 hours, followed by intravenous unfractionated heparin and oral warfarin. Oral anticoagulant treatment was continued for 12 months. His symptoms completely disappeared after three months of treatment. It is important to be aware of this unusual but potentially serious complication, as early diagnosis and treatment may limit morbidity and mortality.
