Computerised Tomographic Angiography (CTA) is less invasive than conventional angiography. It is our perception that CTAs are being requested and performed too frequently at our institution without correct indications. We assessed the number of CTAs that were done, the percentage of vascular injuries sustained and whether correct indications were followed when requesting CTAs. A review of records of the radiology department to determine the number of CTAs done for suspected extremity vascular injuries from January to December 2012. Inclusion criteria were CTAs performed during this period for suspected vascular injuries in fractures and dislocations and extremity gunshot wounds. A retrospective chart review was performed to determine the mechanism of injury, clinical picture (pulses, temperature, capillary refill and neurology), indications for and results of the CTA.Purpose of study
