ABSTRACT
Background:
The first report of ultrasound evaluation in pacas was for gestational diagnosis and monitoring. However,there are no reports of the use of this technique for the evaluation of abdominal structure in pacas. Elucidating the biologyof wild species is important for preservation and potential use as experimental models for human and animal research. Assuch, this study aimed to describe an ultrasonographic view of major abdominal organs and determine the vascular indicesof abdominal aorta and renal arteries in pacas (Cuniculus paca) by Doppler mode.Materials, Methods &Results:
Fifteen adult females with a mean weight of nine kilograms were positioned into dorsal orlateral recumbency. A specific gel was applied, and transabdominal ultrasound examination was performed by a single experienced evaluator using MyLab 30 VET ultrasound equipment (ESAOTE, Italy) with 7.5 and 10.0 MHz linear transducers.Anatomy, biometry and ultrasonographic findings, such as ecogenicity, echotexture and wall thickness of main abdominalorgans (bladder, kidneys, adrenals, spleen, liver, digestive system and ovaries), were assessed during the ultrasound scan.Doppler ultrasound was used to determine the peak systolic velocity (PSV), end-diastolic velocity (EDV), resistance index (RI = [PSV - EDV]/PSV) and pulsatility index (PI = [PSV - EDV]/mean velocity) of the abdominal aorta and renalarteries. The animals were healthy based on physical examination, hemogram and biochemical profile. Furthermore, wedetermined that the ultrasound technique for abdominal evaluation of these animals was feasible. Major abdominal organswere accessed using conventional ultrasonography biometric values and sonographic characteristics. Doppler examinationwas used to determine mean vascular indices of the abdominal aorta and the left and right renal arteries...Palavras-chave
