Transcript of Abdominal aortic aneurysm: endovascular surgery animation

Endovascular surgery is a type of keyhole operation

which can be used to repair an abdominal aortic aneurysm.

The surgeon puts an artificial piece of artery called a stent graft

inside the aneurysm.

The stent is made from a fabric tube supported by metal mesh.

Two small cuts are made in the groin.

A catheter is passed through an artery in the leg to the aneurysm.

Guided using X-ray, the compressed stent is fed through the catheter

and expanded to fit across the aneurysm.

Most stents are made with one leg shorter than the other.

For most patients, a second stent is added to lengthen the short side

and complete the procedure.

The stent protects the aorta walls from pressure and keeps the aorta open.
