I had undergone an angioplasty 6 years ago, how long will my stent last?
Answered by Dr Vijay Surase, renowned cardiologist
Once a stent is delivered or deployed, it cannot and is not removed. Over a period of time this stent becomes a part and parcel of vessel wall. Months later if a small camera (angioscope) is passed through the vessel, the stent cannot be seen as it gets embedded into the vessel wall layer normal cells grow over it covering it completely. This process is called as Endothelization, and it takes a period of 1 month to 1 year depending on the type of stent.
Therefore, it is very important to take dual blood thinners (Aspirin and Clopidogrel) until this time. Once the stent becomes one with the wall of the vessel, the chances of block recurring in the same area are there, but it is equal to the chances of a clot occurring elsewhere in a normal part of the cardiac blood vessels.
