Growth Rate of Aortic Diameter in Patients With Type B Aortic Dissection During the Chronic Phase

Abstract

In type B aortic dissection, the affected aortas have shown a high incidence of enlargement during the follow-up period, and more careful follow-up study is needed for aortic dissections in the thoracic aorta. The presence of blood flow in the false lumen is the most important risk factor for aortic enlargement.
