Iodine contrast extravasation
Extract:
“A man in his 80s with a history of hypertension was admitted to our center for an acute ischemic stroke. An intra- and extracranial computed tomography (CT) angiography was requested in the diagnostic workup. Nonionic iodinated contrast was administered through an intravenous (IV) line inserted in the dorsal venous network in the left hand. After some minutes, painful lesions appeared around the IV line. Physical examination revealed multiple tense bullae over a violaceous base, which soon progressed to the dorsum of the hand and wrist with erosions and ecchymoses (Figure). There were no signs of altered tissue perfusion, and patient sensation was preserved. The patient was diagnosed with iodine extravasation. Supportive measures, stringent dressings, and a combination of topical antibiotics and corticosteroids were prescribed and had excellent clinical outcomes; complete healing was experienced after 3 weeks.”
