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.

The significance of clinically defined subgroups of Alzheimer’s disease [Internet]. Technical Aspects and Clinical Applications, Part 2″. Cerebral amyloid angiopathy CAA is the deposition of amyloid in the wall of intracranial blood vessels, aangiopatia leads to the appearance of hemorrhage, ischemia or leukoencephalopathy.
Reversible leukoencephalopathy associated with cerebral amyloid angiopathy. Strict isolation of features from each lobe is frequently not possible because of extension of hematoma to other lobes, mass effect, and increased intracranial pressure.
The diagnosis of CAA is based on a clinical history compatible, neuroimaging showing hemosiderosis or multiple bleeding, predominantly in posterior fossa, and in some cases histological examination to confirm the presence of amyloid in intracranial microcirculation.
