Complications Of Takayasu's Arteritis To Watch Out For

Aortic Aneurysm

An aortic aneurysm occurs when the wall of the aorta has an abnormal bulge. Aneurysms can occur anywhere along the aorta and take a variety of shapes. Some are round, while others are tube-shaped. An abdominal aneurysm occurs at the portion of the aorta passing through the abdomen. A thoracic aneurysm occurs at the portion of the aorta in the chest cavity. This type of aneurysm significantly raises a patient's chances of an aortic dissection. Though an aneurysm is not generally harmful on its own, an aortic dissection is much more serious. A dissection refers to the tearing of the inner layer of the aorta. Not only does this cause heart damage, but most patients die from an aortic dissection if the blood ruptures through every layer of the aorta. An aneurysm can be caused by Takayasu's arteritis because the repeated periods of inflammation cause the blood vessel walls to stretch and weaken.
