What are the predictors of symptomatic ICH recurrence in CAA
The number of microbleeds and the presence of superficial siderosis on brain MRI predict recurrence risk of intracerebral hemorrhage (ICH) in patients with Cerebral Amyloid Angiopathy (CAA).
Micro- or Macro-Bleeds on Gradient Echo (GRE)
| Number of Micro- or Macro-Bleeds | 3-Year Cumulative Risk of Recurrent Symptomatic ICH (%) |
|---|---|
| 1 | 14 |
| 2 | 17 |
| 3-5 | 38 |
| >6 | 51 |
ICH , Intracranial hemorrhage
Cortical Superficial Siderosis on Gradient Echo (GRE)
| Cortical superficial siderosis | No | Focal | Disseminated |
| 4-year cumulative risk of recurrent symptomatic ICH | 25% | 28.9% | 74% |
ICH , Intracranial hemorrhage
