Research Abstract

The purpose of this study is to establish cerebral aneurysm model in dogs for the study of initiation and development of cerebral aneurysm. Cerebral aneurysms were induced by the treatment of ligation of the common carotid and renal artery, experimental hypertension and β-aminopropionitrile feeding using eleven dogs. Cerebral angiography was performed every three months till 15 months. One animal in the treated group show saccular cerebral aneurysm visualized by cerebral angiography at basilar bifurcation at three months and gradually developed. Histologically, the aneurysm wall was very thin deposited with fibrinoid, internal elastic lamina became thinner and had splits, and number of smooth muscle cells decreased with disturbed arrangement. Thus, this cerebral aneurysm model is similar to that of human. We would like to continue this work for efficiently producing cerebral aneurysm model in large animal.
