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.
