Dear Colleagues,

The workshop session “Animal Models for the Study of Delayed Cerebral Vasospasm and Early Brain Injury after Subarachnoid Hemorrhage” held during Vasospasm 2013 in Lucerne was a great success. The workshop offered the unique opportunity to share experiences and discuss current practices and future prospects of animal models in the field of subarachnoid hemorrhage (SAH) research.

Animal models provide a basis for clarifying the complex pathogenesis after SAH and for the evaluation of potential therapeutic strategies. Despite decades of effort, the translation of basic research into clinically effective treatment has remained poor. Lack of adequate and standardized SAH animal models is one reason for the lack of success.
