Thoracic Aortic Aneurysm (TAA)

Thoracic aortic aneurysm: Overview

A thoracic aortic aneurysm is a bulge in a blood vessel (aorta) in the chest. The bulge occurs in a weak spot in the vessel. A large aneurysm can be very dangerous. If it bursts, it can cause bleeding that leads to death.

A thoracic aortic aneurysm can be caused by an injury to the chest, hardening of the arteries, or an infection. Sometimes aneurysms run in families.

Small aneurysms may not need treatment. But you will need regular checkups to see how fast the aneurysm is growing. An aneurysm may be repaired with a procedure or a surgery if it is large, growing quickly, or causing symptoms.

Clinical Trials for Thoracic Aortic Aneurysm (TAA)

Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials.

Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.
