MayoClinic.com says coronary artery bypass grafting is a surgical procedure that's performed for people with coronary artery disease. In this surgery, a piece of vein is taken from the leg or artery from the chest or wrist. This is attached to the coronary artery above and below the narrowed area to allow blood to bypass the blockage. Because it's an open heart surgery, there are certain complications involved that are higher if the operation is done as an emergency or if the person has other medical conditions.
Wound Infection and Bleeding
The National Heart, Lung and Blood Institute says wound infection is a complication of coronary artery bypass grafting. In case of an infection, the person may experience tenderness, redness or swelling in the area around the incision. Fever or discharge from the wound may also occur. A swelling or bluish discoloration of the skin around the incision indicates there is bleeding. This is another complication of this surgery.
Inflammation in the Lung and Heart Sac
Another complication of coronary artery bypass grafting is inflammation in the lung and heart sac, the National Heart, Lung and Blood Institute says. In this case, patients may also develop chest pain, irritability and loss of appetite. The reaction is usually mild. However, if the fluid buildup occurs around the heart, it may require treatment.
Arrhythmias
Irregularities in the heart rhythm are called arrhythmias. This is also a complication of coronary artery bypass grafting, MayoClinic.com says. In this condition, the person's heart may beat rapidly or too slowly.
Other Complications
Memory loss is possible, and the person may also have problems in concentrating or thinking clearly. Memory problems or problems with thinking clearly may go away within six to 12 months. If a blood clot breaks loose after the surgery, the person may have a heart attack. Kidney failure is another complication; stroke or even death is another risk. Because the operation is performed under anesthesia, reactions to the anesthetic used may also occur.
