The rabbit aneurysm model is a commonly used animal model for studying cerebral aneurysms, particularly in the context of evaluating the efficacy of endovascular treatments such as coils and flow diverters. In this model, an aneurysm is surgically created on the common carotid artery of a rabbit, typically using a combination of an elastase injection and a jugular vein ligation. The resulting aneurysm can then be used to study the aneurysm natural history and aneurysm pathophysiology, as well as to test the effectiveness of various treatment modalities.
