[Aortic dissection without intimal laceration: a case report and review of the problem].

A 43-year-old hypertensive woman with symptoms of aortic dissection was referred to our hospital 3 days after the initial episode. Transesophageal echocardiography and magnetic resonance showed a large intramural hematoma of the ascending and descending aorta without intimal flap and tears. Aortography confirmed the absence of intimal disruption. Medical therapy with beta and alpha blocking agents was established. After 5 months the patient was asymptomatic. On transesophageal echocardiogram and magnetic resonance, complete reabsorption of the hematoma of descending aorta was evident while a clearly identifiable false lumen and intimal flap (without tear) were present at the aortic arch level. The diagnostic criteria and therapeutic options are discussed and the literature on this topic is reviewed.
