R₂eD AVM Hemorrhage Risk
Estimate risk of hemorrhage in patients with cerebral arteriovenous malformations
The management of unruptured brain arteriovenous malformations (AVMs) remains unclear and there may be benefit in developing a predictive tool that could guide hemorrhage risk stratification. The variables used to estimate the risk of presentation with hemorrhage can be summarized by the acronym ReD AVM.
- Exclusive deep location
- AVM size
- Venous drainage (exclusive deep vs other)
- Monoarterial feeding
This tool is meant to supplement clinical decision-making in the treatment of unruptured AVMs. It is best used in conjunction with risk estimates of surgical risk such as the Spetzler-Martin grade.
