Stents – Once in a while, the atherosclerotic plaque is rather cumbersome and narrows the artery lumen shortly after the balloon is deflated.

The stent remains during the vessel and is not taken out. https://carotidarterydiseasetreat77531.blogocial.com/rumored-buzz-on-arterial-vein-disease-singapore-69829731
