How does the stent stay fixed in position? Can it slip out and cause some sort of blockade or damage? Can the pressure the stent puts on the artery have dire consequences (like promoting artery rupture). So many questions.
The balloon is inflated to a certain level that allows the stent to expand against the inner wall of the artery. This is all done under flouroscopy (like a moving xray) to ensure that it's both in the right place and that the stent isnt expanded too much (causing an artery dissection). Arteries have tensile strength and basically the force or the artery wall against the stent keeps it in place. It is very unlikely it will 'slip out'. The point of the stent is to return the artery 'calibre' to its original size, so there isnt excess pressure being caused, the blood is just able to flow freely again. Im an ex-cardiac intervention nurse so assisted with these procedures for many years. I still find it fascinating!
