Caracterización de imágenes ecográficas, mediante el uso de exploración abdominal rápida (AFAST) en atélidos en cautiverio

Abstract

Ultrasound images were characterized in 15 Atélids of the genera Lagothrix lagotricha and Ateles belzebuth using (AFAST) in captivity from Rescue centers and Zoos in the province of Pastaza: Tarqui Zoo, Yanacocha and Merazonia Ecological Reserve, the primates were sedated with tiletamine / zolacepam (8 mg / kg) intramuscularly, an a6v® ultrasound machine with a microconvex transducer was used with frequencies between 4 and 12 Mhz, echographic quadrants corresponding to the species were determined for the AFAST examination: diaphragmatic-hepatic incidence (DH) located in the midline of the retroxiphoid region, splenic-renal incidence (SR) located in the left hypochondrium, cystocolic incidence (CC) located in the prepubic region located in the hypogastrium just in the caudal midline and the hepatic-renal incidence (HR) located in the right hypochondrium; The comparative analysis of images between the two genera showed ultrasound patterns of abdominal organs (liver, spleen, kidneys and bladder) and similar characteristics of shape, topography and ecotexture between the two species; In addition, the topographic anatomy and the normal anatomy of the main abdominal organs were determined: Liver, located in the xiphoid region of regular contour with uniform compact tissue; spleen, located between the umbilical region and the left flank in the mesogastrium with a thin hyperechoic capsule with a normal fusiform shape; Kidneys, located in the right and left hypochondrium correspondingly in the epigastrium, have defined margins with a continuous hyperechogenic capsule of a normal elongated oval shape and a urinary bladder located in the prepubic region, with an echogenic thin wall of smooth contour with a normal ovoid shape; When performing the comparative analysis between the two genders under study, there was similarity in echogenicity and topographic anatomy; In addition, the AFAST protocol allowed a digitalization for anatomical orientation of the structures observed in the images obtained, becoming an important reference guide for doctors and students of Veterinary Medicine.
