Coronary stent dislodgement and migration is a rare phenomenon that can potentially result in life-threatening complications. We encountered the unusual case of a coronary artery stent that stripped from its delivery balloon and embolised into the left internal carotid artery during percutaneous coronary intervention. Such an event is a stressful experience for the interventional cardiologist but also an uncommonly encountered situation for a neurointerventionalist whose expertise may be sought to help navigate the situation. Planning the interventional approach and taking into consideration the tools available as well as potential complications is crucial to maximise the chances of best possible outcome for the patient. We were able to retrieve the stent safely and successfully, but, at the same time, we were prepared to manage any adverse events in the best way possible.
