摘要

對比劑的滲漏為日常放射線學檢查常見問題，組織反應之嚴重程度與滲漏對比劑的量、滲透壓、化學成份有關。在多數情況，對比劑的滲漏是自限性的，滲漏的對比劑會自行吸收而無後遺症。需進一步處理之嚴重合併症，例如皮膚潰爛、壞死、或急性間隔症侯群，雖很罕發生，但須小心觀察情況。對於可能生滲漏之病患，應採用非離子性對比劑，並小心放置塑膠針管。對於已發生滲漏之病患，應仔細觀察情況，並適時採用外科處理。本文回溯文獻報告並討論對比劑的滲漏之危險性及處理方式。

Extravasation of contrast media at injection site is frequently seen in daily radiologic procedures. The severity of tissue reaction to the extravasated contrast media depends on several factors: amount, osmolarity, and chemical components of contrast media. In most cases, self-limited tissue reaction occurs without consequences. Rarely, severe tissue reaction, such as skin ulceration, necrosis or compartment syndrome, may occur which require further treatment. In this article, we reviewed literatures and discussed the risks and management of contrast media extravasation. In conclusion, secure placement of venous catheters for contrast media injection is very important. Using non-ionic contrast media is suggested whenever there is risk of extravastation.
