title: An epidemiological view of vascular trauma in Western Australia: a 5-year study.
abstract: BACKGROUND
  Although Australia encounters vascular injury less frequently than countries such as the USA, the predominance of blunt trauma with associated complex injuries continues to pose problems for clinicians. The present paper reviews Royal Perth Hospital's experience of vascular trauma epidemiology.
  
  
  METHODS
  All individuals who presented to the Royal Perth Hospital (RPH) with a vascular injury between August 1994 and January 2000 were identified from a prospective trauma database. Injuries were classified using the Abbreviated Injury Score (AIS 90 code). The five major vascular injury groups as defined by AIS 90 (neck, thorax, abdomen, upper limb and lower limb) were analysed in turn to determine which injuries were most frequent, what the common causes were, effects of alcohol and drugs, common associated injuries, investigations performed, mortality, proportion of rural vascular trauma with transfer details and lengths of hospital stay.
  
  
  RESULTS
  During the study period, 153 patients (1% of total trauma workload) sustained 175 vascular injuries. The commonest causes of injury for each group were stabbing (neck and lower limb), motor vehicle accident (thorax and abdomen) and work machinery (upper limb). Mortality was highest for thoracic injury (14/32; 44%) followed by abdominal injury (10/29; 34%). The ratio of blunt to penetrating vascular trauma is high and is increasing, as is the ratio of truncal to extremity vascular trauma. The most common artery-vein combination injury was to the femoral vessels.
  
  
  CONCLUSIONS
  The injury patterns emerging from the present study will hopefully help all medical personnel to recognize the potential for vascular injury in a trauma setting.
