Dislodged Deployed DES (Drug-eluting Stent) Dismantles a Doyen—Case report

Abstract

Background: Left main stenting with significant stenosis in symptomatic patients is an alternative strategy of revascularization in cases of low syntax scores with high surgical risk. Stent dislodgement is a rare complication, even rarer when it is already deployed. Percutaneous retrieval of a stent when it is fully deployed, is usually not recommended as it predisposes to a higher rate of dreaded vascular complications. Case presentation: A case of dislodgment of a fully deployed stent in the left main is reported here, which was successfully deployed in another vascular bed without requiring invasive surgical retrieval. Conclusions: Meticulous efforts for stent sizing, landing zone, and balloon expansion are of utmost importance, especially in cases of left main stenting where the risk of systemic embolization is higher. Monitoring stent position during balloon deflation, withdrawal, or manipulation of guide catheters is critical for promptly detecting stent dislodgement. Deploying a fully dilated dislodged stent in a favorable vascular bed is an important bail-out strategy.
