Diagnóstico tomográfico de desvio portossistêmico extra-hepático congênito do tipo porto-gastroesplênico em cão : relato de caso

Abstract

This final paper contains a case report of a congenital extrahepatic portosystemic shunt in an eight-month-old Pug dog. Portosystemic shunts can be classified as congenital or acquired, and extrahepatic or intrahepatic. It is among the most common liver anomalies in dogs. Literature describes the anomaly as causing changes in portal circulation, diverting blood flow before reaching the liver, and consequently leaving the circulatory system susceptible to toxins. Image exams are crucial for diagnosing this anomaly. Treatment can be medication-based and/or surgical, with the former being palliative only, while surgical treatment is sanative with a good prognosis. The goal of this paper is to show the importance of computed tomography for the diagnosis of portosystemic shunts.
