IV contrast infiltration. Treatment is fasciotomy and clean out if there is evidence of compartment syndrome. Otherwise there does not appear to be a general consensus regarding optimal management. Therapies suggested in the literature include elevation of the affected limb, topical application of heat or cold, local injection of hyaluronidase, and aspiration of fluid from the site of extravasation. Of note, contrast extravasation of low osmolar contrast rarely causes severe injuries and is much better tolerated than extravasation of high osmolar contrast.
