Angioplasty for the late stent thrombosis, the new technical challenge: a single centre experience
Insights
Late stent thrombosis (>2 years) after drug-eluting stent implantation is a recognized complication. Percutaneous intervention for these challenging cases requires specific technical considerations.
Area of Science:
- Cardiology
- Interventional Cardiology
- Biomedical Engineering
Background:
- Late Angiographic Stent Thrombosis (LAST) is a recognized complication of drug-eluting stents (DES).
- LAST often occurs after premature withdrawal of antiplatelet therapy.
- Percutaneous intervention for LAST presents unique technical challenges compared to native vessel occlusions.
Discussion:
- This study reports on five cases of LAST occurring more than two years post-DES implantation.
- Percutaneous intervention strategies for these late stent occlusions were explored.
- The technical difficulties and potential solutions for managing LAST were discussed.
Key Insights:
- Drug-eluting stent thrombosis can occur significantly late, beyond two years.
- Percutaneous treatment of LAST is feasible but technically demanding.
- Experience with managing these rare events is crucial for interventional cardiologists.
Outlook:
- Further research is needed to optimize percutaneous strategies for LAST.
- Long-term outcomes following intervention for LAST require investigation.
- Developing standardized protocols for managing LAST is essential.
Abstract:
Late Angiographic Stent Thrombosis (LAST) following drug-eluting stent is quite a well recognised entity today with most reported cases having occurred following antiplatelet therapy withdrawal late after stent implantation. Angioplasty of these late thrombotic stent occlusions poses a new technical challenge quite different from usual native vessel thrombotic occlusions, an issue that has not been addressed at length primarily due to the limited numbers and stray nature of the reports. We herein report our experience with percutaneous intervention in five such cases of late stent thrombosis >2 years following drug-eluting stent implantation from a single centre.
