![]() (Aortic Arch Syndrome, NLM, Medical Subject Headings)Ī congenital vascular abnormality that affects the great vessels and/or aortic arch. Such occlusion may be caused by atherosclerosis, arterial embolism, syphilitic or tuberculous arteritis, etc. Signs and symptoms include weakness, dizziness, arm numbness, blurred vision and transient ischemic attacks.Īny of a group of disorders leading to occlusion of the arteries arising from the aortic arch. It functions as a peripheral chemoreceptor and is composed of glomus cells.Īn artery originating from the aortic arch.Ī syndrome resulting from structural defects of the arteries that arise from the aortic arch. The portion of the aorta following the aortic arch passing into the chest and abdomen creating the thoracic and abdominal segments.Īn artery arising from the aortic arch that supplies the left arm.Ī small mass that is located in the inferior surface of the aortic arch. (Congential Hypoplasia Aortic Arch, NCI Thesaurus) (Left Common Carotid Artery, NCI Thesaurus)Īn artery arising from the aortic arch that divides into the right common carotid and right subclavian arteries.Īn underdeveloped aortic arch that is present at birth. Angioplasty, bypass, and stenting are also used to widen narrowed arteries.An artery arising from the aortic arch that supplies the head and neck. An endarterectomy is the most common procedure for removing plaque and damaged tissue from the inner lining of the arteries. When aortic arch conditions become so advanced that arteries become blocked, surgery to widen or repair narrowed arteries may be necessary. Corticosteroids and immunosuppressant medications, which control the autoimmune response that occurs in Takayasu's arteritis.Blood pressure medications, such as diuretics, beta-blockers, and angiotensin converting enzyme (ACE) inhibitors.Medications prescribed for aortic arch conditions include: Eating a diet low in saturated fat and cholesterol.People who experience blood vessel inflammation and narrowing may slow or prevent the progression of the disease by: Lifestyle modifications and medications are the first line of treatment for aortic arch conditions. Arteriography (also called angiography involves injecting a contrast dye into the arteries and then taking x rays).Other tests that a physician may order include: During this examination, the physician will measure blood pressure and will listen through a stethoscope for abnormal whooshing sounds made by blood rushing through the blood vessel. To rule out any other diseases with similar symptoms, a physician will review a patient's complete medical history and then perform a thorough physical exam. It is difficult to diagnose aortic arch conditions early because symptoms typically emerge only once an artery has narrowed. The cause of aortic arch conditions is unclear. People at increased risk include women and people of Asian descent. In the United States, the estimated incidence of the condition is 2.6 cases per 1 million Americans. They include hypertension, renal (kidney) failure, angina (chest pain), congestive heart failure, transient ischemic attack (TIA, or mini-stroke), and stroke. Serious conditions can occur because of the occlusive phase of the disease. A difference in blood pressure between the arms and the legs.Tenderness above the affected arteries.ĭuring the occlusive phase, symptoms include:.In the first phase, about half of all patients develop one or more of the following symptoms: Later, during the occlusive phase, blood vessels narrow. In the first phase, the blood vessels become inflamed. Symptoms depend on the phase of the disease. Atherosclerosis, or hardening of the arteries, is the most common cause of aortic arch disease. Aneurysms are a life-threatening condition because they can rupture. ![]() Narrowing can reduce blood flow, and weakening can lead to the formation of an aneurysm, or abnormal bulge, in the artery wall. Takayasu's mostly affects Asian females between the ages of 10 and 30.Īortic arch conditions eventually block the blood vessels that branch off the aorta, leading to decreased blood flow to areas of the body. These abnormalities can reduce blood flow to vital organs.Īortic arch disease can result from blood pressure changes, clots, trauma, a congenital disorder (one that is present from birth), or Takayasu's arteritis, an autoimmune disorder that inflames the aorta and the pulmonary artery (the main artery of the lung). Aortic arch conditions are abnormalities in the structure of the arteries that branch off the top of the aorta. It runs from the heart, through the chest, and down into the abdomen.
