Injury to the upper extremity caused by extravasation of contrast medium: a true emergency.

This retrospective clinical study, over a period of four years, includes 16 patients who had extravasation of iopromidum 623 mg (Ultravist 300) in the upper extremity during computed tomography (CT). Although conservative management is sufficient in most cases, seven patients were operated on. The mean time between extravasation and operation was 155 minutes.
