What You Need to Know about Going Home with an Aortic

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.

An aortic dissection is an illness where a
small hole forms and grows in the inner
wall of the aorta. The hole then causes
bleeding into and along the wall of the
aorta. The layers of the aorta split and
make two paths in the artery. In one
path, blood keeps going to the rest of the
body and in the other, the blood stays
still. The still blood can pool blocking
blood flow to the rest of the body. This
causes the aorta walls to weaken and
split more, making the dissection worse.

If a dissection is small, taking medications may help. Pills you will take will lower your blood
pressure and heart rate. This will prevent or slow the dissection from growing. The pressure put
on your blood vessels and heart will be lower.

Your doctor will watch your dissection closely. You will have Computerized Tomography (CT)
scans or Magnetic Resonance Imaging (MRI) scans often to see pictures of it.

Surgery is also an option. During the surgery, the damaged areas of the aorta are removed. A
graft will replace any damaged areas.

Blood Pressure
You will be sent home with your own blood pressure cuff. It is important to keep your blood
pressure under control. This means the top number (systolic blood pressure) is less than 120.
ξ Sitting in a chair next to a table, rest your arm at the same level as your heart. Sit up
straight with your back against the chair. Make sure your legs are uncrossed. Rest your
forearm on the table with the palm of your hand facing up.

ξ Pain can raise your blood pressure. You may also be prescribed pain medication.
Morphine is a common pain medication.

ξ Are obese (a body mass index over 30)
