Does CT scan with intravenous contrast improve the diagnosis of iatrogenic false aneurysms of the ascending aorta compared to aortography?
Does CT scan with intravenous contrast improve the diagnosis of iatrogenic false aneurysms of the ascending aorta compared to aortography?
CT scanning with intravenous contrast may be superior to aortography for diagnosing iatrogenic false aneurysms of the ascending aorta.
May support CT over aortography for iatrogenic ascending aortic false aneurysms; hypothesis-generating and should not change practice yet.
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.
