Injuries to the brachial plexus and subclavian and axillary arteries are uncommon and serious complications of shoulder girdle trauma, due to the close anatomical relationship between them. Neurovascular injuries are most frequent in penetrant lesions, but are are after a closed trauma. When neurological symptoms develop insidiously, some days to weeks after trauma, that should lead to the suspicion of a vascular injury. We report a delayed brachial plexus paralysis in a 39 years old male, who sustained an anterior dislocation of the shoulder ten days before. The DIVAS showed a pseudoaneurysm of the axillary artery and the EMG confirmed the brachial plexus palsy. Treatment consisted in surgical release repair of the vascular defect. One year follow-up show good clinical result.
