Upper-extremity deep venous thrombosis (DVT) is considered an uncommon clinical event with considerable potential for morbidity. This article presents a case of upper-extremity DVT following a clavicular fracture. A 25-year-old man presented with pain and distortion of the left midclavicular area after falling on his left shoulder during martial arts practice. Following physical examination and radiography, he was diagnosed with a simple displaced clavicle fracture at the middle third. The patient had no previous surgery or medical problem, and did not smoke. No family history of blood clotting disorders were present and neurovascular examination appeared normal on the symmetric contralateral side. A figure-of-8 bandage was applied to support the arm and the patient was discharged. One week later, he returned with swelling and severe pain in his left arm. On examination, a DVT was suspected and the figure-of-8 brace was removed. A Doppler ultrasonography was performed and the presence of a thrombus extending from the brachial axillary veins to the distal subclavian vein with no flow in that segment was revealed. The patient was placed in a sling instead of a figure-of-8 bandage to immobilize the arm, while anticoagulation therapy with enoxaparin was started (1 mg/kg every 12 hours, 80 mg subcutaneous daily for 3 months). The swelling was reduced after 5 days. At 2-week follow-up, the patient had no pain and the swelling had completely disappeared.
