Most newborns with symptoms will have surgery either right after birth or soon afterward. First they will receive medications to stabilize them.
Children who are diagnosed when they are older will also need surgery. Usually, the symptoms are not as severe, and more time can be taken to plan for surgery.
During surgery, the narrowed part of the aorta will be removed or opened. If the problem area is small, the two free ends of the aorta may be re-connected. This is called an end-to-end anastomosis. If a large part of the aorta is removed, a graft (using either man-made or a cadaveric material) or one of the patient's own arteries may be used to fill the gap. A tube graft connecting two parts of the aorta may also be used.
Sometimes, doctors will try to stretch open the narrowed part of the aorta by using a balloon that is widened inside the blood vessel. This type of procedure is called a balloon angioplasty. It may be done instead of surgery, but it has a higher rate of failure.
Older children usually need medicines to treat high blood pressure after surgery. Some will need lifelong treatment for this problem.
