RESUMEN
In traffic accidents, wearing a seatbelt can cause abdominal aortic injury due to an abrupt deceleration. We report a case of abdominal aorta dissection caused by a seat belt in a frontal motor vehicle collision. The initial symptoms and signs were vague or uncertain. However, he complained severe abdominal pain with seat belt sign below the umbilicus. Abdominal computed tomography scans showed an initial flap of the abdominal aorta with hematoma and hazy stranding of the mesentery.

PURPOSE: Due to their vulnerability and relatively high driving speed, motorcycles have been associated with a high risk of sustaining multiple severe injuries after traffic accidents. We sought to investigate sustained injuries and the association of accident mechanisms with injury severity for unhelmeted motorcycle accident victims. METHODS: This study was conducted as an observational retrospective study. Unhelmeted motorcycle accident victims who visited the study hospital from January 2010 to December 2011 were included. Data were obtained from medical records, ambulance run-sheets, and telephone interviews. Accident mechanisms were divided into collision with an obstacle, single vehicle accident, collision with another vehicle, collision by another vehicle, and falling accident from the viewpoint of energy. Glasgow coma scale (GCS), Revised trauma score (RTS), and Injury Severity Score (ISS) were analyzed for comparison of injury severity according to the accident mechanisms. RESULTS: Of 404 patients who visited the study hospital, 165 patients were included; 87.3%(144/165) were male, and 78.8%(130/165) were drivers. The incidence of motor cycle accident showed the highest in the teenager and in time during 18:00~24:00 o'clock. Lower extremity was the most common site of injury, followed by upper extremity, head, and face etc. Injury due to falling was the most severe injury mechanism, followed by collision with another vehicle, collision by another vehicle, and a single vehicle and an obstacle (p=0.013). CONCLUSION: Lower extremity injury was the most common injury site in unhelmeted motorcycle accidents, and motorcycle accidents by fall and collision with another vehicle should be considered as a severe mechanism of injury.

Pneumothorax is one of the most frequent complications of percutaneous central venous catheterization.Most significant pneumothoraces are easily detected on postcatheterization chest radiograph.However, we report a rare case of delayed tension pneumothorax detected 4 days after unsuccessful central venous catheterization via the infraclavicular subclavian vein, although initial postcatheterization and postoperative supine chest radiographs showed no active lesion.
