This slowly changed over the years with the use of multi-slice CT scanners. According to our new protocol we are performing only CT- arteriography if this is indicated by the clinical presentation. Patients with “soft” signs of vascular injury underwent CT- arteriography with a 64 or 128 detector row CT scanner if hemodynamically stable. CT- arteriography was also performed on physiologically stable patients if there was uncertainty regarding the site of injury, e.g., multiple gunshot wounds or shotgun wounds. If the patient C59 chemical structure requiring arteriography was physiologically too unstable to be transferred to the CT scanner (approximately 50 meters from our trauma resuscitation area), then arteriography was carried out in the trauma resuscitation area with the use of the Lodox – Scanner (Figure 1) or preoperatively in theatre with a C- Arm.

All patients were given a dose of Cefazolin 1 g. intravenously perioperatively, and the dose was administered every 12 hours for a total of 48 hours. In patients with associated abdominal injury the antibiotic regime consisted of Amoxicillin-Clavulanic acid 1,2 g. intravenously.
