Management of CT Contrast Extravasation

Initial Assessment and Management

The American College of Radiology recommends documenting the incident thoroughly, including patient information, date and time of extravasation, type and amount of contrast media extravasated, signs and symptoms reported by patient, description of IV access, affected area and approximate volume, and management steps with time and date, according to the Annals of Oncology guidelines 1
Photographic documentation is considered for follow-up purposes, as recommended by the Annals of Oncology 1

The Annals of Oncology recommends providing appropriate analgesia for pain control 1

Regular monitoring of the extravasation site is recommended for the first week, with daily or every 2 days follow-up, as suggested by the Annals of Oncology 1
Weekly follow-up is recommended until complete resolution of symptoms, according to the Annals of Oncology 1
Patients should be instructed about potential signs of complications requiring immediate attention, as recommended by the Annals of Oncology 1

Central line extravasation is rare, occurring in 0.24% of cases, but potentially serious, with contrast accumulating in the mediastinum, pleura, or subcutaneous chest/neck tissue, and acute thoracic pain being the most common symptom, as reported by the Annals of Oncology 1
Management steps for central line extravasation include stopping the infusion immediately, attempting gentle aspiration through the catheter, confirming with thoracic CT scan, and considering surgical drainage in severe cases, as recommended by the Annals of Oncology 1

Assess for signs of tissue damage, pain, swelling, erythema, and potential compartment syndrome, as recommended by Anaesthesia 2
