Computed tomography in the diagnosis of iatrogenic false aneurysms of the ascending aorta

Abstract

False aneurysm (contained rupture) of the ascending aorta is a rare complication of aortic valve replacement. The authors have dealt with two such cases that resulted from breakdown of the aortotomy suture line. In both cases, CT scan with intravenous injection of contrast material demonstrated opacification of the lumen of the false aneurysm sac; in neither case was communication with the aorta demonstrable on aortography.
