Aortic Stenting What Is Aortic Aneurysm?
Aortic aneurysm is a bulge in the aorta which is the main artery leading away from the heart. An aneurysm is most likely a result of an accumulation of fatty deposits on the vessel wall.
What Is Aortic Stenting?
An aortic stenting involves two steps :
Insertion of a delivery catheter (small tube) into your artery.
Releasing of the stent graft inside the aneurysm.
1. Catheter insertion
The staff will clean your skin area where the doctor will insert the catheter with an antiseptic solution. This is usually at the top of the leg (groin). You will then be covered with a sterile drape. Next, the doctor will use a small needle to inject some local anesthesia to numb your skin area where the catheter will be inserted. The nurse will give you medication to relieve pain and allow you to relax. You may feel pressure or brief discomfort as the catheter is inserted. The doctor will guide the catheter through the vessel that is to be studied by watching it on a TV-like monitor. You will not feel the catheter moving through your blood vessels.
2. Stent Deployment
When the delivery catheter is positioned inside the aneurysm, the stent is released into the blood vessel. On coming in contact with blood, the stent will expand to a preset size, on occasion ballooning may be require to expand the stent.
