A separate heart-lung machine circuit can be setup, which allows blood to flow to the brain whilst the circulation in the rest of the body is stopped (referred to as “selective antegrade cerebral perfusion”). The patient is cooled to between 18-28 ☌, which reduces the activity of cells in the brain and body to a level low enough that prevents injury from occurring for a short time. Since the circulation is stopped during the repair a number of precautions are taken to prevent brain injury. The circulation through the aortic arch must then be stopped so that the diseased segment can be removed, and a synthetic replacement graft inserted. Then the patient is put on the heart-lung machine and the heart is stopped beating. About the surgeryįirst the heart and aorta is accessed by dividing the sternum (breast bone). The conditions that can lead to this include atherosclerosis (fat and calcium buildup in the arteries), hypertension (high blood pressure), genetic conditions (such as Marfan Syndrome), connective tissue disorders (such as Ehler-Danlos disorder, scleroderma) and direct trauma. These are often life-threatening and require emergency surgery to repair them. Many conditions can cause the aorta to dilate (widen), dissect (tear), or rupture. The branches of the arch supply blood to the brain, head and arms. It first travels upwards, before bending backwards (the arch) and downwards to supply the lower parts of the body. The aorta is the large artery that leaves the heart and provides oxygen-rich blood throughout the body.
