Background

  • Complication of contrast-enhanced CT scanning
    • May also occur from MRI, but rare given low volume used
  • Ultrasound-guided IVs are at higher risk[1]

Epidemiology

  • ~0.5% (range 0.13-0.68%) of cases

Clinical Features

  • Swelling and/or blistering at injection site

Differential Diagnosis

Contrast induced complications

Evaluation

  • Clinical (if no complication)

Management

  • Stop infusion immediately
  • Remove IV canula
  • Ice pack to affected area
  • Elevate
  • Consider hyaluronidase for iodinated contrast through the original IV to be given subcutaneously[2]

Complications

  • 97% have minimal or no injury
    • 79% have localized swelling after extravasation
    • 24% had pain
  • Large volumes (> 50 mL) of high-osmolar contrast media = highest risk

Disposition

  • May discharge after 2 hours with precautions, if no signs of complications.
