Peripheral Parking: A Bailout Strategy for Managing Dislodged Coronary Stents.

Coronary stent dislodgement is a rare but potentially life-threatening complication during percutaneous coronary intervention (PCI). It may occur due to complex anatomy, heavy calcification, tortuous vessels, or equipment malfunction, leading to embolization, vessel injury, or myocardial infarction if not promptly addressed. We present a case of stent dislodgement during transradial PCI, wherein a dislodged undeployed coronary stent migrated to the peripheral arterial system (left common iliac artery) seen on non-contrast computed tomography (NCCT). On subsequent fluoroscopy, the stent was seen aligned with the vessel contour and with good flow across it, so parked permanently without compromising distal flow or limb perfusion. The patient remained hemodynamically stable, and no short-term vascular complications were observed. This case highlights the peripheral parking technique as a practical bailout strategy in scenarios where retrieval is not feasible and the stent is inaccessible or poses a risk of further embolization.
