An endovascular stent is a tube-like device placed inside a blood vessel to help keep it open.
Doctors may recommend this when a blood vessel is narrowed, blocked, damaged, or at risk of collapsing, causing poor blood flow, pain, swelling, or organ problems.
Imaging helps guide the stent into the right position and later helps check whether the vessel remains open and the blood flow has improved.
Imaging guides placement and helps monitor whether the vessel remains open afterward.
It may be used in narrowed or damaged arteries and veins, with follow-up depending on the vessel and condition treated.
This entry explains the procedure. Before you go, read the longer prep guide or find a centre that performs it.
