Angiopatía amiloide en el contexto de hemodiálisis: un terreno desconocido It is known that cerebral amyloid angiopathy (CAA) is due to amyloid beta peptide. Cerebral amyloid angiopathy (CAA), also known as congophilic angiopathy, is a form of angiopathy in which amyloid deposits form in the walls of the blood. Cerebral amyloid angiopathy (CAA) refers to the deposition of β-amyloid in the media and adventitia of small and mid-sized arteries (and, less.
