A large forearm subcutaneous hematoma after contrast extravasation requires surgical managements: A case report.

ABSTRACT

RATIONALE Large extremity hematoma can rarely happen after contrast extravasation during a contrast-enhanced computed tomography scan. Some hematomas need prompt surgical managements. PATIENT CONCERNS A 77-year-old man had acute ischemic stroke and received the thrombolytic and antiplatelet therapies. He had a contrast extravasation during the computed tomography scan and developed a large hematoma in the right forearm, despite without evidence of compartment syndrome. DIAGNOSIS Right forearm hematoma, status post contrast extravasation. INTERVENTIONS: The patient responded poorly to the routine care with arm elevation, cold pack, and wet dressing, and was finally treated by the surgical debridement, vacuum sealing drainage, fascioplasty, and skin flap repair. OUTCOMES: Right forearm wound healed with a scar. LESSONS Large extremity hematoma can happen after contrast extravasation during computed tomography scan, which may require surgical treatments. Careful preparation, close monitor, and prompt managements should be applied in high-risk patients.
