Before proceeding for surgery, it is important to keep the ductus arteriosus open as it allows some blood to reach the different part of the body. Ductus arteriosus is a blood vessel that connects the pulmonary artery to descending aorta in prenatal stage but closes a few days after birth. Once the diagnosis is confirmed, the doctor will prepare for the treatment.įirst, the child’s ductus arteriosus will be observed. If the symptoms of interrupted aortic arch are observed in new-born babies, the doctor will perform a diagnosis with the help of tests like chest x-ray, electrocardiogram and echocardiogram.The condition may also be detected before birth, but it only happens in rare cases. How is Interrupted Aortic Arch treated?Ĭorrective surgery is the only method of treatment for children diagnosed with this condition. Interrupted aortic arch is almost always accompanied by some other heart defect like ventricular septal defect or truncus arteriosus. So surgery will have to be performed within a week after detecting the condition, otherwise lack of blood in the child’s body can prove to be fatal. This condition completely blocks the flow of blood in aorta and prevents oxygenated blood from reaching parts of the body. These symptoms are often detected within a few days of birth. Children affected by this condition may have one or more of the following symptoms such as: As such, there aren’t any preventive measures for this disease either. There are no known causes for this disease, other than genetics.Though it is rare, it can affect any new-born baby. Type C: When the aortic arch is interrupted at the brachiocephalic trunk (rightmost branch on top of aortic arch).Type B: When the aortic arch is interrupted at the left common carotid artery (middle branch on top of aortic arch).Type A: When the aortic arch is blocked at the left subclavian artery (leftmost branch on top of aortic arch).Depending on the site where the interruption or blockage is present, this condition can be categorised as: The ascending and descending aorta are completely separated at the aortic arch in infants suffering from this defect. The curved section is called aortic arch and the part of aorta that heads downwards is called descending aorta. The initial part of aorta that arises from the heart is called ascending aorta. It arises upwards from the left side of the heart, then curves downwards and leads to blood vessels distributed throughout the lower body. The aorta is the largest blood vessel in humans which delivers oxygen rich blood from the heart to the rest of the body. Treatment requires immediate surgery, and delay in treatment may cause the infant to go into shock and may even lead to death. It is detected within a few days of birth, and in some cases, even before birth. In this condition, children are born with an incompletely developed aorta, due to which oxygenated blood cannot be transported to different parts of the body. It is a rare congenital heart condition, that is said to affect about 3 cases per million live births. Interrupted Aortic Arch (IAA) is heart defect that affects children at birth.
