Aortic disease and dissection

Aortic disease can affect the size, shape, or wall of the aorta.

The aorta is the body’s largest artery. Thoracic aortic disease includes several conditions affecting the part of the aorta in the chest. An aneurysm is an abnormal enlargement of the vessel.

A complication clinicians are concerned about is aortic dissection. A dissection occurs when a tear allows blood to separate layers of the aortic wall. It is a medical emergency.

Seeing the aorta

CT and MRI help clinicians evaluate anatomy.

Computed tomography

CT can provide detailed images of the aorta and help clinicians assess its size, shape, and location.

Magnetic resonance imaging

MRI can also show the aorta’s size, shape, and location without using ionizing radiation.

Why blood flow matters

Hemodynamics describes how blood moves.

No single measurement tells the whole story. Clinicians consider aortic size and growth together with symptoms, family history, genetic findings, valve anatomy, and other factors.

Researchers study whether blood speed and forces on the aortic wall can add context to what clinicians see on anatomical images.

Third Coast Dynamics is developing technology to help clinicians build a more individualized picture of aortic disease by bringing blood-flow information together with anatomy.
