Uncommon congenital and acquired aortic diseases: role of multidetector CT angiography. Hemiarch replacement is defined as the proximal arch repair beyond the level of the innominate artery without involving the arch vessels, and total arch replacement is the replacement of supra-aortic vessels as an island or individual branched grafts. The diagnosis of an adult-onset aortic aneurysm has traditionally been regarded as a rare condition, but this has increased significantly in recent years. Papadakis MA, et al., eds.
