Duplex-Doppler ultrasonography for morfologycal and hemodynamic evaluation of aorta and cranial mesenteric arteries in dogs

Abstract

The knowledge of the normal Doppler signs of each blood vessel is important in their identification. There are few reports in veterinary literature that describe the normal aspect of abdominal blood vessels in dogs. The aim of this paper was verify technical viability of US Doppler use to assessment of the abdominal aorta and cranial mesenteric arteries; twenty clinically normal unsedated dogs were examinated. It was described and assessed characteristic duplex color Doppler spectrum of each blood vessel and the results were compared with that found in literature. Although some technical limitations were found, US Doppler could be successfully used as a noninvasive method to detect mesenteric blood flow changes in dogs without chemical contention.
