Abdominal Aortic Aneurysm Mouse Model

Abdominal aortic aneurysm (AAA) is a common degenerative disorder associated with sudden death due to aortic rupture. Current therapy is endovascular stents or open surgical repair of the aorta, excluding the aneurysm from the circulation. There are a number of different animal models of abdominal aortic aneurysm. Large animal models are mostly used to develop novel surgical methods to treat abdominal aortic aneurysms. Small animal models developed in rodents, are employed to further understand the mechanisms involved in development of abdominal aortic aneurysm in order to identify potential new medical treatments.
