Upper limb deep vein thrombosis as complication of acromioclavicular joint dislocation.

Around 5%-10% of deep vein thrombosis occurs in the upper limb. Its most frequent cause is usually cancer, central venous catheter, radio-chemotherapy or hormonal treatment. Less commonly, trauma around the shoulder region can also be a cause of deep vein thrombosis. Its diagnosis is probably more complex than in the lower limb due to its low frequency and clinical suspicion, as well as the clinical presentation, 50% of the cases being asymptomatic or presenting only with mild neck pain or omalgia. Because of their infrequency, therapeutic recommendations are based on indirect evidence from studies of deep vein thrombosis of the lower limb, considering oral anticoagulation the best treatment. We report a case of deep vein thrombosis in the upper limb after trauma to the shoulder causing grade III Rockwood acromioclavicular dislocation.
