The aorta is a large artery that travels through the chest and abdomen to supply the legs with blood and oxygen. If you have an aneurysm it means that somewhere along the wall of the artery, an abnormal bulge has developed. In most cases these bulges occur in the abdomen or chest (thoracic) area. Aneurysms can burst and be life-threatening, so your doctor may suggest surgery to repair the artery. In most cases this means replacing the bulging area with a graft. Learning all you can about your condition and this procedure will help you work with your medical team to avoid complications. However, all types of surgery involve some risks and you should know what they are before you have the procedure.
General Complications
There can be complications with any surgical procedure. This includes a general risk of infection, excessive bleeding, kidney problems, breathing problems or complications from the anesthesia. The risk of complications in part depends on your age and general health before the procedure as well as the extent of the repair that needs to be done.
Other Complications
The Case Western Reserve University Health System states that with an aortic aneurysm repair you may experience swelling or infection near the incision site. Respiratory or urinary infections and problems with the heart, colon or kidneys can also occur. In some cases the graft can become infected. During or after surgery some patients suffer a heart attack or stroke. The National Institutes of Health state that "Death soon after the operation occurs in 5-10 percent of patients."
Rare Complications
According to the Society for Vascular Surgery, "Paralysis in the lower half of the body is very rare following abdominal AAA surgery but can occur more commonly following extensive thoracic aortic aneurysm operations." Another complication for men includes an inability to obtain an erection after surgery. These complications are caused by scar tissue that blocks the surrounding nerves. This inhibits the nerves' ability to transmit signals.
