Mural repair following obliteration of aneurysms: production of experimental aneurysms.

One hundred thirty-two experimental rat carotid artery aneurysms were produced using a variety of methods, in order to determine which of these approaches should be employed in the development of a satisfactory laboratory model. The gross appearance and pathomorphology of aneurysms created by vein pouch and partial arteriotomy methods most closely resembled those features reported in clinical intracranial aneurysms.
