- Abstract
With the use of a fotonic sensor oscillographic tracings of vibrations were recorded from the adventitial surface of experimentally induced aortocaval and carotid-jugular arteriovenous fistulas in rabbits and compared with those obtained from surgically created lateral aneurysms of the rabbit aorta and common carotid arteries and berry aneurysms of the aortic bifurcation. The displacement/time tracings of the arteriovenous fistulas exhibited considerable vibrational activity over a wide range of frequencies especially in the range of 10 to 35 cps. the random nature of the recordings being characteristic of turbulent flow. Unlike the fistulas, the aneurysms exhibited no thrill nor did the recordings exhibit the random appearance of turbulence, There was variation in the vibrational activity of the aneurysms and in several an accentuation of the incisura and dicrotic wave.
