[Aortic dissection: false negative results of aortography and thoracic CAT, report of a case]. / Disección de aorta: falsos negativos de aortografía y TAC torácico, a propósito de un caso.

Acute dissection of the aorta is a relatively frequent clinical entity, with a poor prognosis and a global mortality of 40% during the first 48 hours. A correct diagnosis and an early surgical treatment may modify the natural course of the dissection of aorta. We present a case of a patient with high clinical suspicion in the aortography, thoraci CAT and transthoracic echocardiogram (TTE). However, it was not possible to establish the diagnosis. The transesophagic echocardiogram (TEE), on the contrary, suggested the presence of dissection of aorta, as was later verified in the necropsis methods, seems to support the TEE as the first election method in the dissection of aorta.
