title: Acute type A aortic dissection following intramural hematoma of the aorta. A case report.
abstract: A seventy-three-year-old woman had symptoms of aortic dissection. Initial computed tomographic (CT) scan and angiography showed an extensive intramural hematoma (IMH) of the aortic segment from the ascending aorta to the bulk of the descending aorta without intimal tear or false lumen. Two weeks later the patient's symptoms recurred. A repeat CT demonstrated a classic type A aortic dissection with a false lumen and an intimal defect. The patient underwent a successful hemiarch repair with use of selective cerebral perfusion under profound hypothermic circulatory arrest. This case suggests extensive IMH as an important underlying pathology of the aortic dissection.
