Background Coronary stent avulsion is a rare, infrequently reported complication of percutaneous coronary intervention (PCI) with no consensus on management options. Case summary This case series presents three descriptions of iatrogenic coronary stent avulsions, and three different bailout management strategies. All patients presented with acute coronary syndrome and required PCI. In the first case, a freshly implanted stent was entrapped in a coronary guidewire and avulsed upon withdrawal of the wire into the aortic sinus. In the second case, a staged procedure to implant a new stent was complicated by stent dislodgement and entanglement with a recently implanted stent leading to avulsion of both stents into the aortic sinus and resultant dissection to the coronary arteries. In the third case, following a successful stent implantation, the tip of the coronary guidewire was bound to the proximal edge of the stent resulting in avulsion of the newly implanted stent into the ascending aorta upon retraction of the wire at the end of the procedure. The first two patients were managed percutaneously, and the third surgically. All patients have had acceptable technical and clinical outcomes. Discussion In the absence of a consensus on best bailout management strategy, we discuss the mechanisms of and the potential management options for this rare, but serious, complication.
