Faux anévrisme de l’artère sous-clavière compliquant une fracture de la clavicule

The post-traumatic false anevrisms of the subclavian artery are rare; they exceptionally occur in a context of sports injury. They are, in most cases, the consequence of an artery pinning due to fractured clavicle. Both painful mass and traumatic history make the clinical diagnosis easier. The ischemic signs are rare and neurological ones reflect a brachial plexus injury. Doppler ultrasound and angiography have facilitated the procedures of diagnosis and contribute to the choice of the surgical approach and surgical tactics. Angiography as a diagnosis investigation is almost abandoned, but it triumphed among the ways of management once endovascular treatment is considered. Surgery remains the treatment of choice; it includes the flattening of the false aneurism, a restoration of arterial continuity and stabilization of clavicular fracture in the same operation. We report the case of a 30-year-old young man who, after a sport accident, had a fracture of the right clavicle with a false aneurism of the subclavian artery discovered 3 days after the trauma. He had received a flattening of the false aneurism and internal fixation with a clavicular bone plate with a favorable outcome. In this work, we remind the circumstances of occurrence, diagnostic and management therapeutic features of these rare lesions.
