Usefulness of transesophageal echocardiography in the diagnosis of aortic intramural hematoma

Aortic intramural hematoma or atypical aortic dissection is an aortic dissection without intimal tear nor flow communication and it may be the first step of a typical dissection. We describe five cases, in which transesophageal echocardiography detected intramural hematoma of the aorta. Transesophageal echocardiography is a safe, accurate and specific method that allows bedside diagnosis as well as follow-up of patients with hematoma of the aorta.
