Open repair of an abdominal aortic aneurysm (AAA) GHPI0205
This leaflet helps you to understand the important things about having treatment of an Abdominal Aortic Aneurysm (AAA).
Overview and symptoms
An abdominal aortic aneurysm (AAA) is a bulge or swelling in the aorta, the main blood vessel that runs from the heart down through the chest and tummy.
About the operation
An open repair of an aortic aneurysm is a major operation which involves replacing the aneurysm with a man-made synthetic graft or tube. This may be carried out through a large incision (cut) in the abdomen.
The type of operation you have will depend on your general health and the size and shape of your aneurysm. This will be discussed with you by your consultant before the surgery.
- Not having surgery is always an option. The risks of having or not having the surgery will be discussed with you at your clinic appointment.
- Endovascular aneurysm repair (EVAR) is minimally invasive surgery performed through small cuts in your groin, the aneurysm is repaired using stent graft that is placed inside the artery to strengthen the aneurysm and prevent it bursting (rupturing).
- Laparoscopic (keyhole) assisted surgery where several small cuts and one slightly larger one are made in the abdomen.
Benefit of having surgery
To prevent the aneurysm from bursting in the future. If the aneurysm is not repaired there is a risk of not surviving if the aneurysm bursts.
Risks and complications
- Heart failure, kidney failure or damage to the bowels
- Chest infection, infection of the graft or wound.
- Blood clots forming in the legs or lungs (Deep Vein Thrombosis, DVT or Pulmonary Embolism, PE).
- Pressure sores. To reduce this risk the nursing staff will help you to move regularly while you are confined to bed. They will also encourage you to get up and move around as quickly as possible.
- Your overall fitness will affect the success of the operation but your consultant will discuss this with you.
- Your sexual activity may be affected after aneurysm surgery. If you have any concerns about this please mention it to your consultant.
- There is a 5% chance that you will not survive the operation.
What to expect
You will be admitted to hospital on the day of or the day before your operation. You will be in hospital for from 3 to 10 days depending on the type of operation you have.
After your operation you will be transferred to the Department of Critical Care (DCC) for careful monitoring.
This is planned and it is important that your relatives and friends are aware that this is normal procedure.
It is possible for you and your family to visit the department the day before your operation. This can help to reduce any concerns about the amount of equipment used in the department. You will remain in the DCC until you are stable enough to be transferred to a surgical ward. However, if a critical care bed is not available on the day of your surgery, it would be unsafe to carry out your operation. This will mean that you will be discharged home and be given another date for your operation.
While you are a patient in the DCC the physiotherapist will visit you to show you how to do breathing and leg exercises. This is to help prevent blood clots forming you will also be given small daily injections of a medication to thin the blood.
You will have some pain and discomfort after your operation and you will be given strong pain relief to help control this. After the operation pain relief is usually given through a continuous drip going into your back, this is called an epidural.
The anaesthetic doctor and a specialist nurse will monitor this closely to make sure that the pain control is working. Your pain relief will be gradually reduced. When the epidural is removed you will be given pain relief tablets or suppositories regularly. Some patients may have a fine tube delivering local anaesthetic directly into the wound to help with pain control.
Diet and fluids
You may not be able to eat for several days after surgery, as sometimes the intestine does not work immediately after the operation.
During this time you will be allowed to drink small amounts of water and will be given fluid through a drip (a tube inserted in to a vein in your arm).
You may also have a tube passed through your nose into your stomach when you are asleep during the operation. This is to drain any fluid from your stomach and prevent vomiting. Once you start passing wind the tube will be removed and you will be able to drink larger amounts of fluid and food will gradually be introduced.
Bowel movements and passing urine
You are unlikely to have your bowels open for the first few days after the operation. Once they begin working again you may experience diarrhoea which will usually settle within 24 hours.
A catheter tube will be passed into your bladder during the operation to drain away the urine. This will be removed when you are mobile and able to walk to the toilet.
Dissolvable stitches or small metal clips will be used to close your wound(s) which will be checked regularly. The clips will be removed 10 days after your operation by the district nurse; the ward staff will arrange this.
You will be able to shower or take a bath before you are discharged home.
You will feel weak after the operation but this is normal. Once you are able to move around the ward on your own and you are eating and drinking normally, arrangements will be made for you to go home. It is important that you have restful periods and gradually build up to your normal activity each day.
Recovery can take several months. You are advised to avoid heavy lifting for 2 months.
You can begin driving again when you can perform an emergency stop comfortably and without hesitation. Most patients take about 4 weeks to reach this level safely. We advise you to inform your car insurance company that you have had an operation.
You will be seen in the outpatient clinic about 2 to 6 weeks after your discharge.
