Overview and Facts about Aortic Arch Replacement
Aortic arch replacement is a procedure in which the “arch” of the aorta is surgically removed and replaced with a synthetic graft. The aorta is the body’s main blood-supplying artery, extending from the heart to the abdomen.
The arch is located at the peak between the ascending and descending aorta. The arch extends the vessels that supply blood to the brain, head, neck and arms.
The arch replacement may be necessary in cases of an aneurysm (enlargement of the aorta) or dissection (tear of the inner lining of the aorta) at the arch of the large artery.
Surgical intervention may be necessary in these cases to prevent the risk of decreased blood flow to the organs or the rupture of the aorta. Both are potentially lifethreatening events.
What are the Risks with Aortic Arch Replacement?
Aortic arch replacement is an open -heart surgery performed by a cardiac surgeon with expertise in the procedure. Once you are asleep under general anesthesia, the surgeon will begin by opening your chest with an incision over your breastbone.
Your heart will be stopped and then placed on a cardiopulmonary bypass that keeps oxygenated blood circulating through your body via a heart-lung machine. The aortic arch is removed, and a synthetic graft is stitched into place between the ascending and descending aorta. The blood vessels that extend from the arch are reconnected to the aorta with another, three-branched graft.
You will be closely monitored in the intensive care unit for a day or so following surgery. You can expect to remain in the hospital for about a week while your doctors and medical team monitor your postsurgery progress, including your blood pressure, blood flow and heartbeat.
Once you are determined healthy and strong enough to go home, your care team will go over everything you need to know to continue your recovery and cardiac rehabilitation.
You will receive detailed instructions on cleaning and caring for your incision and what activities should be avoided and for how long.
What are the Side Effects of Aortic Arch Replacement?
Side effects are common to any open heart procedure. These postsurgical after-effects usually begin to subside within four to six weeks and can often be minimized with treatment and support advised by your doctor.
Possible side effects include:
-
Appetite loss
-
Clicking noise or sensation in your chest
-
Difficulty falling or staying asleep
-
Pain or tightness in your back or shoulders
-
Pain, redness or swelling at the site of the incision
