CTICasesTraumatic subclavian artery injury and SC joint disruption
Imaging findings
CT scan of a patient following a saw accident shows a clavicle fracture, sternoclavicular (SC) joint subluxation/disruption with a surrounding hematoma, an ossified costal cartilage fracture, a small lung hernia, and a left subclavian artery intramural hematoma.
Key takeaways
High-force chest wall trauma near the thoracic outlet can cause sternoclavicular joint dislocation/disruption. The displacement of bones or costal cartilages can compress or injure the adjacent subclavian vessels, leading to occlusion or intramural hematoma.
