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

Abstract

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. The most complicated postoperative course occurred when the operation was delayed 300 minutes after extravasation. When patients were treated early, there was no permanent postoperative impairment. Extravasation of contrast is an increasing cause of potential complications in the forearm as a result of the use of power injectors in CT. Immediate assessment by an experienced plastic surgeon followed by either conservative treatment or quick intervention if necessary may avoid serious damage.
