Coarctation of the aorta

A stenosis can be located anywhere in the thoracic and abdominal aorta. However, it is encountered most often at the opening of the ductus arteriosus or ligamentum arteriosum.

If the narrowing is proximal to the origin of the ductus arteriosus, this is called preductal coarctation of the aorta or aortic coarctation of the infantile type. If the lower part of the body is supplied with non-oxygenated blood through a patent ductus, cyanosis of the lower half of the body is apparent.

In postductal coarctation of the aorta or aortic coarctation of the adult type, the narrowing is distal to the ligamentum arteriosum. The lower half of the body is supplied through collaterals.

Coarctation of the aorta can usually be operated without using extracorporeal circulation. Access is through a left lateral thoracotomy.
