Thoracic aortic dissection (AD) is one of the most common aortic emergencies. It 
can be fatal if not promptly diagnosed and treated. Intramural hematoma (IMH) of 
the aorta is recognized as distinct from classic (double-barreled) AD. IMH also 
frequently leads to aortic emergency, which can be fatal unless rapidly 
diagnosed and treated. Recently, thoracic endovascular aortic repair (TEVAR) has 
been used for the treatment of complications caused by AD. TEVAR is also a 
viable option for the treatment of complicated IHM. In this article, we review 
the details of TEVAR as treatment options for AD and IMH, including the 
indications for TEVAR, imaging, and follow-up.
