Atypical Presentation of Intramural Hematoma of the Ascending Aorta Using a Conservative Approach

Aortic intramural hematoma is a severe disease, secondary to vasa vasorum bleeding and/or aortic micro-ulcers without connection with the true lumen of the vessel. Its occasional finding in the absence of symptoms or aortic trauma is quite rare. In this report, an asymptomatic female patient with involvement of the ascending aorta and transverse arch was maintained on clinical treatment, despite the prevailing recommendations for surgical repair in Stanford type A lesions. Relevant aspects of lesion characterization in different imaging tests, identification of high risk anatomical criteria and conduct are discussed. A satisfactory 7-month follow-up was observed.
