Background: A primary splenic torsion occurs when the organ rotates around its vascular pedicle in the absence of any other concomitant disease. The occurrence of primary splenic torsion is rare, with a prevalence lower than 1%. Splenic torsion is more often related to dilated gastric volvulus syndrome, and it has no clear etiology despite reports that associate it with congenital abnormalities or traumatic ruptures of the gastrosplenic or splenocolic ligaments. This study reports a case of splenic torsion in an American Pit Bull terrier dog, its related symptomatology, and the treatment adopted.Case: A 3-year-old male American Pit Bull terrier dog weighing 32 kg was admitted to the hospital with symptoms of acute abdomen, lethargy, increased abdominal volume, discomfort, restlessness, and with a history of collapse three days prior to admission. Clinical examination revealed lethargy, pale mucous membranes, reduced capillary refill time, moderate dehydration, and hyperthermia. Abdominal palpation revealed increased abdominal volume in the epigastric and mesogastric areas. CBC and serum biochemistry profile revealed hypochromic normocytic anemia, leukocytosis with absolute neutrophilia and eosinopenia, mild hypoalbuminemia, and thrombocytopenia. PCR for detection of Babesia sp. and Ehrlichia sp., which returned negative results, and measurement of clotting time, which was prolonged, were performed to exclude immune-mediated hemolytic anemia. Radiographic and ultrasonographic images showed a normal stomach, but revealed presence of splenomegaly. An exploratory laparotomy allowed direct observation of the spleen, which exhibited an increased volume, a blackened, cold, hyperemic appearance, and a complete torsion of the splenic vascular pedicle; the surgical team opted to perform total splenectomy rather than undoing the pedicle twist. The animal returned to the hospital after 10 days exhibiting an excellent clinical condition.[...](AU)
