Surgery of the Aorta
Abdominal and Thoracic Aortic Aneurysm


The Aorta

There are two types of blood vessels in the body – arteries and veins. Arteries carry
blood rich in oxygen from the heart to all the organs of the body. Veins carry blood back
to the heart. The aorta is the largest artery in the body. It is also the most important
blood vessel. If there is a problem with your aorta or arteries, the blood flow to the rest
of your body is decreased.

There are two types of arterial disease: atherosclerosis and aneurysm. With
atherosclerosis, the walls of the arteries are narrowed because of plaque build-up and can
form a blockage. This occurs slowly over time. The plaque is made up of fat, cholesterol
and calcium deposits. It can result in less blood flow to your legs and other organs.

An aortic aneurysm is a weakened part of the artery. It looks like a bulge or balloon in
the wall of the vessel. It can occur in the part of the aorta that is in the chest or in the
abdomen. In the abdomen, it is called an abdominal aortic aneurysm (AAA). If it is in
both the chest and abdomen, it is called a thoraco-abdominal aneurysm (TAA). It also
can occur in the iliac, femoral or popliteal arteries. If the aneurysm bursts or tears, it can
cause life-threatening bleeding.

There can also be a blockage of the aorta further down your body. This can decrease
blood flow to your legs. Surgery can help bypass or remove the blockage. This will
increase the blood flow to your legs.








Blood clots can also form in aneurysms orstick to the wall of the arteries causing
atherosclerosis. These blood clots can break off and lodge in the artery and block blood
flow. This is called an embolus.








Risk Factors for Atherosclerosis
ξ Age
ξ High blood pressure
ξ Diabetes
ξ Smoking
ξ High cholesterol
ξ Obesity
ξ Lack of exercise
ξ Family history

Symptoms of Arterial Disease
ξ Leg pain while walking that goes away with rest
ξ Pain at rest, if blockage is severe
ξ Discolored skin
ξ Legs are cool to touch
ξ Loss of hair on toes, feet and legs
ξ Thick toenails
ξ Numbness and tingling
ξ Ulcers
ξ Male impotence


Symptoms of aneurysm - you may not have any symptoms but these may be
present:
ξ Back pain
ξ Abdominal pain
ξ Chest pain (thoracic aneurysm)
ξ Pulsating feeling in abdomen
ξ Discolored feet


Diagnostic Tests

Routine tests will be done to diagnose your blood vessel disease. They may include:

ξ Computerized Tomography (CT) or Ultrasound: shows that a blood vessel is
narrowed or blocked
ξ Angiogram: an x-ray that can pinpoint a blockage or aneurysm in your arteries.
ξ Magnetic Resonance Angiogram (MRA): an imaging technique that uses a strong
magnet, radio signal, and a computer to produce pictures of the blood flow from
your arteries.
ξ Ankle Brachial Pressure Index (ABI): The ABI test uses sound waves to measure
the blood pressure in your arms and ankles using a small, hand held device called
a Doppler. It is done to check for peripheral arterial disease.

Treatment to fix a blockage depends on the extent of your disease and your health. Mild
disease may improve with:

ξ Exercise
ξ Control of risk factors (see risk factor list above)
ξ Balloon angioplasty or stenting

Operations

Operations to fix an aortic aneurysm or blockage in the aorta or other artery are done
under general anesthesia. This means you will be asleep during surgery. This type of
surgery takes three to six hours. Based on the site of your disease, your surgeon will
make an incision into either your chest or your abdomen. If you are having an
aortobifemoral bypass, you will have an incision in your abdomen and in each side of
your groin.

During the surgery, the surgeon puts clamps above and below the damaged or blocked
part of your aorta. To fix an aneurysm, the surgeon opens the damaged part of your
aorta. Then, the surgeon sews in a fabric graft to make the walls of the aorta stable. To
bypass a blockage, the surgeon sews a fabric graft to the aorta above and below the
blockages. This is called a bypass because the graft will send blood around the
blockages. To remove a blockage, the surgeon cuts the plaque that is causing the
blockage from the blood vessel wall. The incision is then closed with staples or stitches.
A dressing is put over your closed incision.

What to Expect before Surgery

You will not be able to eat or drink anything for at least 6 hours before your surgery. The
day before your surgery you may need to have a bowel prep to clear your bowel out for
surgery. You will be told if you need to do this.

What to Expect during Surgery

Surgical techniques include:

ξ Endarterectomy or removal of the plaque. The plaque is cut from the blood vessel
wall.
ξ Embolectomy or removal of a blood clot.
ξ Placement of an artificial graft.

The incision is then closed with staples or stitches. A dressing is put over your closed
incision.





What to Expect after Surgery

After surgery you may be moved to an intensive care unit (ICU) or to an intermediate
care unit (IMC). We will closely watch your heart rate, blood pressure, and blood
oxygen level. If you are moved to an ICU, you will be moved to a standard hospital
room 1-3 days after surgery.

When you wake up you will have some tubes and lines attached to you. At first, you may
have a breathing tube to help you breathe. It will be taken out when you can breathe on
your own. You will have an intravenous line (IV) in your arm or neck for medicine and
fluids. You will also have an arterial line. This is in the artery in your wrist and is used
to measure your blood pressure and draw blood. You will have a Foley catheter in your
bladder to drain urine. You may have other drains either in your stomach, your incision,
or your spine. You will be given medicine to help manage your pain.

You may have blood tests, x-rays, ultrasounds or other procedures. You may also need to
wear compression stockings. They help prevent blood clots in your legs. You will not be
able to eat or drink for a few days. You will slowly be able to eat more each day. As you
recover, you will work with nurses and physical therapists to get back your strength.

Most patients who have this surgery can go home within 5-7 days.



Wound Care

Your incision is closed with stitches or staples. You may get it wet in the shower. Do
not swim or take tub baths until okayed by your doctor. You may clean the incision
gently with mild soap and water. Remove any dried drainage. Do not scrub the incision.
Rinse it and pat dry. Do not use any lotions, alcohol or powders until told by your
doctor. You will receive instructions before you go home. Most incisions can be left
open to air except for incisions in the groin. These should be covered with a dry gauze
dressing or Mepilex dressing. Be sure your incision is dry before you apply the gauze or
Mepilex dressing.

At your first or second clinic visit after discharge, your staples or stitches may be
removed.


Activity

When you go home you should be able to do most of your basic daily routines. You will
need to give yourself time for rest. You will tire easily. You may feel weaker. This is
normal. Your strength and energy level will increase as your body heals.

Walking is good for you. Start slowly and increase your distance a little bit each day.
This will help you get stronger. Walking also helps prevent constipation and blood clots.

You will have some restrictions. For the first few weeks after surgery:

ξ Do not life more than 10 pounds during the first 6 weeks at home. This includes
groceries, pets and children. One gallon of milk weighs about 8 pounds.
ξ Do not drive until your doctor says it is okay. Do not drive while taking narcotic
pain medicine.
ξ Do not play contact sports or do exercise other than walking until your doctor
approves.
ξ Ask your doctor at your first clinic visit when you may return to work and resume
sexual activity.


Pain

It is normal to have some pain at your incision. You may also have pain in your
abdomen, chest, back or groin. The pain will decrease as the incision heals. You should
take the pain medicine prescribed by your doctor. As time passes, you should need less
pain medicine. You may then wish to use an over-the-counter pain medicine but talk to
your doctor before starting this. It may interfere with other medicines you are taking. Do
not drive while taking narcotic pain medicine.


Narcotic pain medicine can make you constipated. Use over-the-counter stool softeners
as needed. Drink plenty of fluids and eat high fiber foods. Fruits and vegetables (prunes,
raisins, apples, oranges, potatoes, spinach and carrots) and whole grain breads or rice
have fiber. Staying active also helps prevent constipation.

Diet

You may have loss of appetite and even lose weight. You should still try to eat because a
healthy diet helps your body heal. You may want to eat small amounts of food several
times a day instead of eating three large meals.

You should also drink enough fluid to stay hydrated. Dehydration can make you feel
more tired and weak. Drink at least 8 to 10 eight-ounce glasses of fluid each day. Water
and milk are good options. Limit the amount of caffeine drinks (soda, coffee) because
they can dehydrate you.

Eat a heart healthy diet:

ξ Eat less saturated fat. Eat less fatty meats, fried foods, butter and whole milk
dairy products. Eat more fish, chicken, turkey and veal and less beef, lamb and
pork.
ξ Limit eating organ meats (liver, kidneys, etc) to once a month.
ξ Use polyunsaturated oils, such as canola, safflower, soybean, sunflower, sesame
and cottonseed oils.
ξ Drink skim milk instead of whole milk.
ξ Eat sherbet or Italian ice instead of ice cream.
ξ Eat less trans fats. Eat less sweets such as donuts, cookies, and desserts.
ξ Eat less carbohydrates. Eat less sugars and sweetened drinks.
ξ Eat less sodium. Eat less processed foods. Do not add extra salt to your food.
ξ Eat less cholesterol. Eat less egg yolks and shrimp.


Antibiotics

If you have an artificial graft, you may need antibiotics before any future surgery, certain
dental procedures, and other invasive procedures (colonoscopy, etc.). Tell your dentist or
doctor about your artificial graft so antibiotics can be given. This may prevent a graft
infection.

Leg Swelling

As you become more active, your legs may become swollen. If this happens, elevate
your legs when you sit. Your doctor may want you to wear anti-embolism stockings or
ace bandages when you go home. These help reduce swelling and return blood to the
heart. Apply them before walking. If you wear ace bandages, they should be wrapped

snugly from toe to knee. Your nurse will show you how to wrap them. Remove them
when you go to bed.

You may need to wear stockings or ace wraps for the first 2 weeks, or until the swelling
is gone. If swelling persists, keep wearing them for support. Ask your doctor when you
can stop wearing them.

Do not wear clothes that constrict your legs or feet such as tight socks or garters. Buy
shoes that fit well to prevent pressure sores or swelling in your feet. Wear socks with
your shoes to prevent blisters.

Leg and Foot Care

To help prevent foot problems, follow these guidelines:

ξ Look at your legs and feet daily. If you can’t see them, have someone else check
them. Let your doctor know if you see any sores, scratches, cracks, blisters or
reddened areas.
ξ Wash your legs feet daily with mild soap and water. Do not soak your feet. Dry
them well.
ξ Put lotion on dry skin daily. Do not put lotion between your toes.
ξ Avoid soaking your feet for long periods. It dries out your skin. Always check the
temperature of the water with your hand or elbow instead of your foot.
ξ Let a doctor or nurse clip your toenails or show you how to clip them.
ξ Wear shoes that fit well.
ξ Wear white cotton or wool socks.
ξ Check shoes and socks for stones, sharp things, or holes.
ξ Protect your feet from extreme heat and cold.
ξ Avoid walking barefoot.
ξ Do not use heating pads or heat lamps on your feet or legs.
ξ See a podiatrist if you need corns, calluses or ingrown toenails removed.


Smoking

Try to quit smoking. Smoking delays wound healing, and can decrease blood flow, shrink
arteries, and raise your blood pressure. If you’d like help quitting, call the Quit Line:
1-800-QUITNOW (784-8669)

Follow up

You will be seen in the Vascular Surgery Clinic about 2 weeks after you go home. If you
still have staples or stitches, they may be removed at this visit.
