ABSTRACT
Stent loss is a rare complication that occurs when the stent detaches from the deploying balloon. This event is not necessarily followed by stent loss. The operator still has an opportunity to retrieve the stent from the arterial system of the patient. It is therefore appropriate to define stent separation as the detachment of the stent from the balloon followed by successful stent retrieval, and to define stent loss as the detachment of the stent from the balloon without stent retrieval.
