This anomaly results from regression of the right arch (between the right common carotid and right subclavian arteries) including the right ductus arteriosus (Fig 6). [10] Innervated by barometric nerve terminals, the aortic arch is responsible for sensing changes in the dilation of the vascular walls, inducing changes in heart rate to compensate for changes in blood pressure. Since so much blood flows through the aorta, it is an extremely sensitive blood vessel during trauma or certain types of medical conditions. However, medications may be used to treat high blood pressure, high cholesterol and other conditions linked to aneurysm. In fact, for many people, the diagnosis of a TAA comes as a result of an imaging study, such as a CT scan, MRI, or echocardiogram, during evaluation for something else.
