We report a rare case of iatrogenic arterial cannula transection during a dressing change and migration of the distal fragment within the radial artery. The retained intraarterial fragment was successfully located using ultrasound, enabling swift surgical removal. We discuss the risk factors associated with arterial cannula transection and the efficacy of imaging modalities in locating the intraarterial fragment.
