VASCULAR INTERVENTIONS

Aortic Aneurysm Resection

Aortic aneurysm resection involves

removing an aneurysmal segment of

the aorta. The surgeon first makes an

incision to expose the aneurysm site.

He then clamps the aorta, resects the

aneurysm, and repairs the damaged

portion of the aorta by sewing a

prosthetic graft into place.

Aortic Endovascular Stent Graft

Endovascular stent grafting is a

minimally invasive procedure used

to repair AAA and other aneurysmal

arteries by reinforcing the vessel

walls. The surgeon uses fluoroscopic

guidance to insert a delivery catheter

with an attached compressed graft

through a small incision into the

iliac or femoral artery. The catheter

is advanced into the aorta and

positioned across the aneurysm below

the renal arteries. The stent graft

prevents blood from entering the

aneurysmal area of the artery but

maintains blood flow distally. This

helps prevent the aneurysm from

enlarging and possibly rupturing.
