Aortic Dissection

Alternate Names : Aortic Dissecting Intramural Hematoma, Dissection of the Aorta, Dissecting Aortic Aneurysm

How is the condition diagnosed?

The history and physical exam may make a healthcare provider suspect aortic dissection. An ECG, or electrocardiogram, may reveal a pattern associated with high blood pressure. A chest X-ray may show an abnormally shaped aorta. The X-ray may also show fluid in the lungs, known as pulmonary edema, or around the heart, known as pericardial effusion.

Special X-ray tests are used to confirm the diagnosis. A cardiac catheterization involves the insertion of a tube through the skin and into an artery. This tube can be threaded up into the aorta and injected with contrast agent. As the contrast agent moves through the aorta, pictures can be taken. If a dissection is present, it can be seen. Other types of special X-rays can also be used to make the diagnosis.
