16884 Complex Aorta Surgery

Overview

Complex aortic surgery is a major operation to repair a seriously damaged or enlarged part of the aorta. The aorta is the body's largest blood vessel — the main pipeline carrying blood from your heart to the rest of your body. 'Complex' means the repair is more than a simple straight patch. It may involve the aortic root (the part right next to the heart), the aortic arch (the curve at the top), or the long stretch that runs down through your chest and belly. During surgery, the damaged section is usually replaced with a strong man-made tube called a graft. Surgeons may also need to reconnect or bypass the smaller arteries that branch off the aorta to supply your brain, arms, kidneys, gut and legs. Some people need this operation as an emergency after a sudden tear in the aorta (an aortic dissection). Others have it as a planned operation to fix an aneurysm — a ballooned, weakened area that could burst if left alone.

Planned complex aortic surgery is uncommon. Aortic aneurysms and other aortic problems are much more common than the surgery itself — many are found early and simply watched. Only a small number of people ever need this kind of operation, and it is carried out in specialist centres.

Symptoms

Common symptoms

• Many people have no symptoms at all before planned surgery — the problem is spotted on a scan done for another reason.
• Chest or upper back pain that may be dull or nagging.
• A hoarse voice or a tickly cough that will not go away, because an enlarged aorta can press on nearby nerves.
• Trouble swallowing, or a feeling of pressure in the throat or neck.
• Breathlessness, or a pounding feeling in the chest.
• Belly or lower back pain if the affected section runs through the abdomen.

Symptoms in children

• Often no symptoms — the problem may be found during checks for a heart or connective tissue condition.
• Tiredness or breathlessness when playing.
• Poor feeding or slow weight gain in babies.
• A heart murmur heard by a doctor.
• Chest pain is uncommon in children, but it should always be checked.

Symptoms in older adults

• Tiredness and breathlessness with everyday activity.
• A hoarse voice or a cough that lingers.
• Back or belly pain that comes and goes.
• Feeling full quickly, or losing weight without trying, if the aorta presses on the gut.
• Symptoms are sometimes put down to 'just getting older', so scans matter.

Causes

Main causes

• Aortic aneurysm — a weakened area of the wall that balloons outwards.
• Aortic dissection — a tear in the inner lining of the aorta.
• Connective tissue conditions such as Marfan syndrome or Ehlers-Danlos syndrome, which make the vessel wall weaker.
• A bicuspid aortic valve or another heart problem present from birth.
• Hardening and narrowing of the arteries (atherosclerosis).
• Infection of the aorta, which is rare.
• Chest injury, or problems following earlier heart or aortic surgery.

Risk factors

• High blood pressure — the single biggest risk.
• Smoking, or having smoked in the past.
• Getting older.
• A family history of aortic aneurysm or dissection.
• High cholesterol, diabetes and being overweight.
• Connective tissue disorders, or a bicuspid aortic valve.
• Inflammatory conditions affecting the blood vessels.
• Use of stimulant drugs such as cocaine.

When to see a doctor

See a doctor urgently if:

• New chest, back or belly pain that worries you.
• A hoarse voice or trouble swallowing that does not settle.
• After surgery: fever, or a wound that is red, hot, swollen or leaking.
• Feeling faint, or much more tired than usual for no clear reason.
• Any new weakness or numbness in your legs.

Book a routine appointment if:

• You have been told you have an aortic aneurysm or a widened aorta and are due a check-up or scan.
• You have a family history of aortic aneurysm, dissection, or a connective tissue condition.
• You have a heart murmur, or were born with a heart valve problem.
• You would like to talk about blood pressure, stopping smoking, or your overall risk.

Diagnosis

Aortic problems are usually found with imaging scans. You may be seen by a cardiologist (heart doctor) or a heart and blood-vessel surgeon, who will look at the size and shape of your aorta, how quickly it is changing, how well your heart valve is working, and your general health. This helps the team decide whether to watch and wait, or to plan surgery.

Tests that may be done

• Echocardiogram — an ultrasound scan of the heart and the first part of the aorta.
• CT scan or MRI scan — detailed pictures of the whole aorta.
• Chest X-ray.
• ECG, a tracing of the heart's electrical activity.
• Blood tests, including kidney function and cholesterol.
• Lung function tests and a general fitness check before surgery.
• Sometimes an angiogram, where dye is used to show blood flow.

What to expect at your appointment

Most tests are quick and painless. A CT or MRI scan means lying still for a short while, and the dye used in an angiogram can make you feel warm for a moment. You may have several appointments before any decision is made. Bring someone with you if you can, and write your questions down — it is easy to forget them on the day.

Treatment

Treatment depends on the size and growth of the aorta, your symptoms and your general health. There are three broad paths: careful monitoring with medicines and regular scans; endovascular repair, where a stent-graft (a fabric tube held open by a metal mesh) is guided through a blood vessel in the groin to line the aorta from the inside; and open surgery, where the damaged section is replaced with a graft. Complex cases may need a hybrid approach that combines both. Your specialist team will explain which option suits you and why.

Self-care at home

• Take your medicines exactly as prescribed, especially blood pressure medicines.
• Check your blood pressure at home if your team asks, and keep a record.
• Stay smokefree, and ask for help if you need it.
• Keep every follow-up scan appointment, even when you feel well.
• Follow your team's advice about lifting, driving and returning to work after surgery.
• Keep surgical wounds clean and dry, and report redness, heat or discharge.
• Build activity back up slowly — short walks first, then a little more each day.

Medical treatments

Before surgery, and sometimes instead of it, treatment focuses on lowering the strain on your aorta. That means bringing blood pressure down to a target your doctor sets, lowering cholesterol, controlling blood sugar if you have diabetes, and treating pain. You may be given medicines that slow the heart rate and reduce the force of each heartbeat. Your doctor will also review other conditions and any medicines that could affect your heart or blood vessels, and will treat infection if there is any. All of this is adjusted over time, and your team will explain any change before it is made.

When is surgery considered?

Surgery is usually considered when an aneurysm reaches a size your team considers risky, if it is growing quickly, if you have symptoms, or if there is a tear, leak or dissection. People with connective tissue conditions or a bicuspid valve may be advised to operate at a smaller size, because their risk of complications is higher. Planned surgery is generally safer than emergency surgery, which is why regular scans matter so much.

Living with this condition

Recovery from complex aortic surgery takes time. Expect some days in intensive care, then a hospital ward, and then weeks at home feeling more tired than usual. Most people need two to three months before they feel close to themselves again, and full recovery can take longer. You will have a scar and possibly some early restrictions. Gentle, steady progress is what counts — try not to compare yourself with anyone else.

Lifestyle tips

• Keep your blood pressure in the target range your team sets.
• Stay smokefree — this is the single biggest thing you can do.
• Be active in a way you enjoy, such as walking, swimming or flat cycling.
• Work towards a healthy weight.
• Keep alcohol within recommended limits.
• Go to every follow-up scan and appointment.
• Tell any new doctor or dentist that you have had aortic surgery.

Diet and exercise

A balanced diet rich in vegetables, fruit, whole grains, beans, fish and lean protein helps your blood pressure — go easy on salt, sugary drinks and heavily processed food. After surgery, start with short walks and build up gradually. Your team will tell you when you can lift heavier things and when you can drive. Avoid heavy straining and sudden hard effort until you are told it is safe, and check with your team before starting anything strenuous, including contact sports or heavy weights.

Mental health and emotional wellbeing

It is very common to feel anxious, low or shaken after major heart surgery, especially if your operation was an emergency. Some people have upsetting dreams, or find themselves checking their chest for pain. This usually eases with time, but help is there if it does not. Talking to your clinical team, a counsellor, or other people who have been through the same operation can make a real difference. If you ever feel unable to cope, or have thoughts of harming yourself, contact your local crisis line or emergency services straight away — you deserve support.

Prevention

Not all aortic problems can be prevented, especially those caused by conditions you are born with. But you can lower your risk, and slow problems down, by keeping blood pressure under control, not smoking, staying active, eating well, and attending any scans you are offered.

Screening programmes

There is no routine test for everyone. Screening may be offered if you have a strong family history of aortic aneurysm or dissection, or a condition such as Marfan syndrome. If a close relative has had an aortic aneurysm, tell your doctor — they can arrange an ultrasound scan, which is quick and painless.

Complications

If left untreated

• An aneurysm can keep growing and, rarely, burst — this is a medical emergency.
• A tear (dissection) can reduce blood flow to the brain, kidneys, gut or legs.
• Damage to the aortic valve, which puts extra strain on the heart.
• Blood clots, or internal bleeding.
• Pressure on nearby nerves and organs, causing voice or swallowing problems.

Long-term outlook

The outlook is often good. Many people who have complex aortic surgery return to a full, active life, and regular follow-up means problems are less likely to be missed. Recovery takes patience, and some people need lifelong checks — but that monitoring is a safety net, not a sign that something is wrong. Your team will explain what to expect in your own situation.
