Avaliação Ultrassonográfica em Cachorros-do-Mato (Cerdocyon thous, Linnaeus, 1766)

Abstract

Ultrasonography is an widely used imaging diagnostic technique in veterinary medicine, gaining ground in wild animal medicine. This study describes the ultrasound anatomy of crabeating-foxes. The animals were sedated with meperidine, acepromazine and propofol. The lumen of the gallbladder presented anechoic and homogeneous, and the mean of the measurement of its wall was 0.17 cm. The prostate was identified caudal to the gallbladder, with average values of 1.61 cm and 1.21 cm for length and height, respectively. The splenic parenchyma was characterized by a homogeneous and hyperechoic appearance, with a mean of 1.21 cm. The average size obtained for the left and right kidney was 4.09 and 4.16 cm and the width of 2.12 and 2.24 cm, respectively. Only the left ovary of one of the females was identified, located caudally to the kidney. The liver showed smooth contours, with intermediate echogenicity in relation to the spleen and renal cortex, and uniform ecotexture. To its right, the gallbladder was identified as an anechoic structure, with a mean of 0.11 cm. The stomach and intestine walls measured 0.24 cm and 0.37 cm, respectively. The testicles had an oval contour with their major axis located dorsocaudally, measuring the right 1.83 and 0.94 cm and the left 1.77 and 0.82 cm. The ultrasonography was effective in getting information about the anatomy from the studied species, and it has assisted in the generation of parameters.
