Contrast Media Extravasation Injury

SUMMARY

Extravasation of contrast medium during injection, especially when doing contrast-enhanced CT, is now a common problem. The risk factors include patient factors, the class of contrast medium used, and the injection technique. The mechanisms discussed are effects of osmolality, cytotoxicity, volume, and compression. The clinical picture varies from no subjective complaints to pain, ulcers, and compartment syndrome. However, nearly all cases can be effectively handled by simple conservative treatment with a cold pack and elevation of the arm. The treatment and follow-up of the patient must be documented.
