Methods  Retrospectively analyzed the date of the 17 198 patient using contrastenhanced CT scan during January 2014 and December 2015, and to investigate the potential risk factors and related preventing measures. Results There were 18 cases of contrast agent extravasation occurred, accounting for 0.10%. The age (less than 10 yrs or over 60 yrs), tumor, vascular puncture site (forearm venules, hand vein) , the injection velocity (3～4 mL/s) and osmotic pressure (＞500 mOsm/kgH2O)are potential risk factors of contrast agent extravasation. Conclusion The occur of contrast agent extravasation is assoicatewd with varied risk factors. Preventive measures such as medical health education, technique of puncture and puncture, puncture site selection and application of high pressure syringe should be carried out to reduce the risk of contrast agent extravasation.
