This procedure is done to replace a segment of the aorta or iliac arteries, which are the large arteries in the abdomen feeding the lower body with blood. Surgery is necessary to treat aneurysm in which the blood vessel is swollen and weakened and prone to rupture, or for blockage because of arteriosclerosis.

In either procedure, the affected artery is replaced with a synthetic graft by making an incision in the abdomen and usually in the groins. This is a major operation with a significant amount of discomfort in the first few days, especially due to the necessity of a nasal tube to keep the stomach decompressed until the intestinal activity has resumed. Once this has occurred, then a light diet is ordered and if that is tolerated, then the patient can be discharged to continue rehabilitation at home.

Once home, a walking regimen and low-fat diet should be followed. Walking is the most important thing you can do after this procedure, along with your deep breathing exercises.

A low fat means keeping the fat calories as low as possible, but no more than 30% of your overall calorie intake. For example if you eat 1,500 calories per day, eat no more than 50 fat grams per day. A well-balanced meal includes protein, carbohydrates, vegetables, fruit and an adequate fluid intake. More information on a well-balanced diet can be found in the books you receive from the cardiac rehabilitation nurse.

Since prescribed pain medication may cause constipation, an over-the- counter laxative such as milk of magnesia can be helpful, but don't overuse it.
