Imagen ecográfica de la obstrucción biliar extrahepática en el perro: descripción de 7 casos

espanolSe realizo un estudio ecografico en siete perros que presentaban un cuadro de ictericia por obstruccion biliar extrahepatica. Esta tecnica permitio llegar al diagnostico en seis de los casos. Se estudio la imagen ecografica de la dilatacion de las vias biliares intra y extrahepaticas, asi como los signos asociados, tales como la presencia de una masa en el area pancreatica, que pudiesen orientar sobre el origen de la obstruccion. * An ultrasonographic examination was carried in out 7 dogs with icterus due to an extrahepatic biliary obstruction. This technique allowed the diagnosis in 6 of the dogs. The sonographic appearance of the dilated intra and extrahepatic biliary tree was assessed, as well as the associated lesions, such as the presence of a mass in the pancreatic area, which could guide towards the origin of the obstruction.
