Occult thoraco-abdominal injuries from an airbag and seatbelt

Abstract

A combination of a seatbelt and airbags decreases the risk of injury for most body regions in motor vehicle crashes. Although the severity of injuries decreases, injuries still occur. We report a case of occult thoraco-abdominal trauma in a patient who was wearing a three-point seatbelt and had airbag protection. A 59-year-old man presented to the emergency department in shock after a motor vehicle accident. He was protected by a three-point seatbelt and airbag. Chest radiographs and focused assessment with sonography for trauma showed no abnormalities. However, computed tomography revealed multiple injuries in the chest and abdomen. This case report highlights occult thoraco-abdominal trauma in a victim protected by a seatbelt and airbag, which may be a pitfall for emergency physicians. Emergency physicians should understand the limitations of chest radiographs in trauma evaluation and carry out a complete evaluation of patients.
