Vascular injuries following road traffic collisions in a high-income developing country: a prospective cohort study.
BACKGROUND
The mechanism and pattern of vascular injury vary between different populations. The commonest mechanism of vascular injury in civilian practice is road traffic collisions. We aimed to prospectively study the incidence, detailed mechanism and anatomical distribution of hospitalized vascular trauma patients following road traffic collisions in a high-income developing country.


METHODS
Data were collected prospectively on road traffic collision injuries in the whole city of Al-Ain, United Arab Emirates, from April 2006 to October 2007 with full details of mechanism of injury and its relation to sustained injuries.


RESULTS
Out of 1008 patients in the registry, 13 patients had vascular injury, a calculated incidence of 1.87 cases/100 000 inhabitants per year. There were eight car occupants, four pedestrians, and one motorcyclist. Upper limb vascular injuries were the most common anatomical site (n = 4) followed by thoracic aorta (n = 3). All thoracic aortic injuries were acceleration injuries (pedestrians hit by a moving vehicle). None of the eight car occupants was wearing a seatbelt and the majority sustained a front impact deceleration injuries. The median injury severity score, hospital stay, and ICU stay were significantly higher in the vascular injury group compared with nonvascular group (P < 0.0001). Three patients died (23%); two due to severe liver trauma and one due to rupture thoracic aorta.


CONCLUSIONS
The incidence of hospitalized vascular injury due to road traffic collisions in Al-Ain city is 1.87 cases/100 000 inhabitants. These injuries occurred mainly in the upper part of the body. Seatbelt compliance of car occupants having vascular injuries was very low. Compliance with safety measures needs more enforcement in our community.
