Abstract:
Cerebral amyloid angiopathy (CAA) is a cerebral small vascular disease caused by pathological deposition of β-amyloid protein in cortical and pial arteries and capillaries. It is the main cause of non-traumatic cerebral lobular hemorrhage and has a high risk of recurrent hemorrhage. Studies have shown that specific imaging markers, such as cerebral microbleeds, cortical superficial siderosis, convexal subarachnoid hemorrhage, centrum semiovale-perivascular spaces and the overall burden of cerebral small vascular disease, may be more effective in predicting the risk of bleeding recurrence in patients with CAA. This article reviews the imaging markers used to predict the risk of recurrent bleeding in patients with CAA, in order to provide a new direction for the establishment of a risk assessment system for recurrent bleeding.
