A Rodent Model for Chronic Brain Hypoperfusion Related Diseases: Permanent Bilateral Occlusion of the Common Carotid Arteries (2VO) in Rats.

Permanent occlusion of bilateral common carotid arteries (2VO) in rat is considered as a suitable animal model to mimic chronic brain hypoperfusion status, which is proved to be a risk factor to precede the Alzheimer's disease or/and vascular dementia. In this protocol, we describe how to successfully ligate the bilateral common carotid arteries covered by anterior cervical muscle group, and provide the details for understanding the surgical procedures of 2VO.
