Ascending Aortic Aneurysm
is an enlargement (dilatation) of the ascending aorta.
"By definition, an aneurysm is a localized or diffuse dilation of an artery with a diameter at least 50% greater than the normal size of the artery."
Aortic aneurysm cause weakness of the aortic wall and increase the risk of rupture - when untreated immediately, results in shock and death.
Conservative therapy of aortic aneurysms is based on strict blood pressure control to prevent further expansion of the aneurysm. The definitive treatment may be endovascular repair or open heart surgery with replacement of the part of aorta with graft.
