Purpose:
We sought to define the sensitivity and specificity of computed tomographic angiography (CTA) in pediatric vascular injuries.
Methods:
All neck and extremity CTAs performed in pediatric patients at a level 1 trauma center were reviewed from 2001 to 2007.
Results:
Overall, 78 patients were identified with an average age of 15.0 +/- 4.0 (0-18 years). Males outnumbered females 3.6:1. CTA was performed for 41 penetrating and 37 blunt traumas. Most penetrating injuries were due to missile wounds (71%) or stab wounds (17%). Eleven major vascular injuries resulted from penetrating trauma. For penetrating trauma, CTA was 100% sensitive and 93% specific. CTA for penetrating trauma had a positive predictive value (PPV) of 85% and negative predictive value (NPV) of 100%. Most blunt injuries were due to motor vehicle accidents (57%), followed by pedestrian hit by car (27%). Eight major vascular injuries resulted from blunt trauma. For blunt trauma, CTA was 88% sensitive and 100% specific. CTA for blunt trauma had a PPV of 100% and an NPV of 97%. The accuracy for penetrating and blunt trauma was 95% and 97%, respectively.
Conclusions:
CTA is highly sensitive, specific, and accurate for pediatric neck and extremity vascular trauma.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
