Why can’t we just bore/remove the clogging material in arteries than just putting in a stent in Angioplasty?
In: Biology
1. The plaques are pretty tightly bound to the walls of the arteries. Think plaque on your teeth.
2. If a piece of even moderate size breaks free, it could cause a stroke in a few seconds.
So, stents are the invasive option that gives the most benefit for the lowest risk. Although for most patients, the long-term outcome of a stent is not statistically better than using medication instead.
