[Repair of aortic arch aneurysm protruding to the retrobronchial space--a case report].

Abstract

A case of pseudoaneurysm of the aortic arch which protruded to the retrobronchial space is reported. A 73-year-old female complaining of severe chest pain was transferred to our hospital, CT showed an abnormal mass which occupied the retrobronchial space and displaced the esophagus toward righ, associated with left pleural effusion. A pseudoaneurysm of the aortic arch was suspected. Angiography revealed an aortic arch aneurysm protruding to the retrobronchial space. Emergent total arch replacement was performed. We diagnosed it as an impending rupture of the aortic arch aneurysm with a specific shape.
