Insights
Coronary stent dislodgement is rare but dangerous. This case report details the successful retrieval of a dislodged coronary artery stent from the carotid artery, highlighting crucial interventional planning.
Area of Science:
- Cardiology
- Neurology
- Interventional Radiology
Background:
- Coronary stent dislodgement and migration are infrequent but serious complications during percutaneous coronary intervention.
- These events can lead to severe neurological or cardiovascular sequelae, necessitating specialized management.
Observation:
- A case is presented where a coronary artery stent dislodged from its delivery balloon during percutaneous coronary intervention.
- The dislodged stent subsequently embolized into the left internal carotid artery, posing a significant neurovascular risk.
Findings:
- The interventional team successfully retrieved the dislodged coronary stent from the left internal carotid artery.
- Meticulous planning, appropriate tool selection, and preparedness for adverse events were critical for a successful outcome.
Implications:
- This case underscores the importance of neurointerventional expertise in managing rare stent migration events.
- Effective management requires a multidisciplinary approach, careful procedural planning, and readiness to address potential complications during complex interventions.
Abstract:
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.
