Surgery Overview
Aortobifemoral bypass surgery is used to bypass diseased large
blood vessels in the abdomen and groin.
To bypass the blocked blood vessel, blood is redirected through a
graft made of synthetic material (such as polytetrafluoroethyline [PTFE] or
Dacron). This graft is sewn above and below the diseased artery so that blood
flows through the graft. These man-made grafts are more likely to be used than
transplanted natural grafts for aortobifemoral surgery, because the blood
vessels involved are large.
The artificial blood vessel is formed into a Y shape. The single
end of the Y is sewn on the aorta. The two split ends of the Y are sewn below
the blocked or narrowed areas of the femoral arteries. This allows the blood to
travel around (bypass) the diseased areas. See a picture of
aortobifemoral bypass
.
General anesthesia is used and will cause you to sleep through the
procedure.
What To Expect After Surgery
Because this surgery is done on large, deep blood vessels inside
the abdomen, recovery times are longer than for bypass surgery to treat
diseased blood vessels in the legs.
You will need to spend 24 to 48 hours in bed after the surgery and
will be in the hospital for 4 to 7 days.
Why It Is Done
Aortobifemoral bypass surgery is for people who have blocked blood
vessels (aorta or iliac arteries) in the abdomen and pelvis. The blockage
usually must be causing significant symptoms or be limb-threatening before
bypass surgery is considered.
How Well It Works
Aortobifemoral bypass grafts stay open about 90% of the time for at
least 5 years.1
Risks
Risks for aortobifemoral bypass procedure include:
- Failed or blocked
grafts.
- Bleeding.
- Infection.
- Heart
attack.
- Stroke.
- Sexual dysfunction caused by nerve
damage in the pelvis.
What To Think About
Bypass surgery is preferred for people who have many areas of
blockage or a long, continuous blockage in the arteries of the abdomen and/or
the pelvis.
Angioplasty may be preferred for people who have a
small number of short, narrowed areas in the arteries of the leg or
pelvis.
