Experimental Production of Carotid Aneurysms

Abstract

RUPTURE of an intracranial aneurysm is one of the most common causes of sudden death in young adults. The surgical treatment of these "berry" aneurysms has now developed to a stage where knowledge concerning their hemodynamic characteristics is desirable. The present report is concerned with a method of producing "berry" aneurysms of the common carotid arteries of dogs, together with preliminary studies of intra-aneurysmal hemodynamics.The initial attempts at aneurysm production were by injury to the arterial walls. Incision of the adventitia and media did not cause an aneurysm to form. In the words of John Hunter,¹ who tried this . . .
