[Intramural aortic hematoma and anticoagulation].

Intramural aortic hematoma is one of a group of conditions covered by the term acute aortic syndrome. Many aspects of its natural history remain poorly understood, and the best treatment is not known. The aim of this study was to describe the clinical and radiological characteristics and follow-up of a group of patients with intramural aortic hematoma who received anticoagulant therapy during hospitalization. We selected a prospective cohort of patients with a diagnosis of intramural aortic hematoma and carried out an analysis of those who received anticoagulation treatment during the acute phase of the illness. Patients received anticoagulation for a range of different reasons. In all patients, the intramural aortic hematoma was observed to undergo gradual regression despite anticoagulation therapy.
