Diagnosis: Contrast extravasation
While the risk of extravasation itself is not increased with the use of power injectors, there are certain conditions that do increase a patient’s risk for extravasation.
Most extravasations are limited to the adjacent soft tissues and self limited.
Optimal management for contrast extravasation varies depending on the amount of contrast extravasated and patient’s symptoms.
In this case, the patient presented with compartment syndrome which would require a surgical consultation.
Compartment syndrome from contrast extravasation is a result of having increased volume introduced into a closed space.
