Torção esplênica primária associado à baço acessório em cão / Primary splenic torsion associated with accessory spleen in a dog

Background: Primary splenic torsion occurs when there is a splenic vascular pedicle rotation without association of otherdiseases, as the Gastric Dilatation Volvulus (GDV). Accessory spleen consists in a splenic tissue fraction independentfrom main organ, caused by a spleen defect in the embryonic development, most remaining asymptomatic and discoveredincidentally. They have their own blood supply, which is usually from a branch of the splenic artery. Present report represents a primary splenic torsion with the accessory spleen finding in a dog.Case: A 7-year-old female mongrel was referred to Veterinary Hospital of Universidade Federal do Rio Grande do Sul,showing pain and firm consistency in the left abdominal region, prostration and inappetence four days before the medicalappointment. At the clinical examination, the patient was alert, 7% dehydration, hypocorous mucous membranes, withoutalteration in lymph nodes, left abdominal pain. Laboratory tests, chest radiographic and abdominal ultrasound was requested.Two images compatible with splenic image were visualized, one with a regular structure without vascularization suggestingsplenic torsion and another with homogeneous parenchyma and echogenicity of the normal spleen, with vascularizationsignal. The animal was referred to the surgical procedure and the anesthetic induction protocol with propofol (6 mg/kg-1)and ketamine hydrochloride (2 mg/kg-1) and maintenance with total intravenous anesthesia with propofol (0.2-0.4 mg/kg-1/min) and lidocaine (2 mg/kg-1), in a semi-closed loop and spontaneous ventilation. The pre-retro-umbilical incision in theventral midline was performed, and the exploratory celiotomy was done. During the cavity exploring, a small amount of freefluid and a structure compatible with the spleen were observed. It was noted that the splenic vascular pedicle was twistedaround its axis and the gastroesplenic and splenocolic ligaments were also involved...(AU)

Leiomioma intestinal em um equino: relato de caso / Intestinal leiomyoma in a horse: case report / Leiomioma intestinal en un caballo: estudio de caso

Elleiomioma es un tumor benigno originado a partir de células de músculo liso. La mayoría de tumores benignos dei intestino delgado no muestran síntomas y suelen ser hallazgos incidentales durante procedimientos como Ia laparotomía exploratoria o necropsia. Sin embargo, dependiendo dei tamaõo dei tudisminución de lumen asa intestinal puede conducir a signos clínicos tales como cólico y compresión. EI pestudio reporta un caso de un caballo pérdida de peso presentando cuatro anos de edad, Ia fatiga después ejercicio y calambres recurrentes. Los ensayos identificados fue una masa dura, redonda en Ia región dei fiizquierdo de aspecto ecográfico heterogéneo. Laparotomía exploratoria se realizó revelando una masa tuque invade ellumen dei yeyuno dei mango y el plexo vascular mesentérica. Esta masa se eliminó a través de enterectomía y se mantuvo citológico e histológico diagnosticar un leiomioma. Oespués de 19 días tue dadoalta el paciente y el propietario informó el aumento de peso y un mejor rendimiento.(AU)

Leiomyoma is a benign tumor originating from smooth muscle cells. Most small intestinetumors don't show clinical signs and usually are incidental findings during procedures like exploratoryor necropsy. However, depending on the size of the tumor, the reduced lumen of intestinal loop mayclinical signs of colic and impactation. This present paper reports a case of a four year old equine thatprogressive weight loss, post exercise fatigue and recurrent colic. Through examination, a rigid roundheterogeneous ultrassonographic appearance mass was found in the left flank. An exploratory celiomperformed revealing a mass tumor located in jejunum invading the lumen and the mesenteric vascularThis mass was removed through enterectomy and held cytological and histopathological exams dignleiomyoma. After 19 days the pacient was discharged and the owner reported weight gain and pertoimprovement.(AU)

Leiomioma é um tumor benigno originário de células do músculo liso. A maioria dos tumores benignos de intestino delgado não demonstram sintomas e geralmente são achados acidentais durante outros procedimentos como celiotomia exploratória ou necrópsia. Porém, dependendo do tamanho do tumor a diminuição do lúmen da alça intestinal pode levar a sinais de abdômen agudo compatíveis com afecções não estranguladas do intestino dos equinos. O presente trabalho relata o caso de um equino de quatro anos de idade que apresentava emagrecimento progressivo, fadiga pós-exercício e cólicas recidivantes. Após palpação retal e exame ultrassonográfico foi identificada uma massa rígida e arredondada em região do flanco esquerdo. Foi realizada celiotomia exploratória revelando uma massa tumoral em jejuno invadindo o lúmen da alça e o plexo vascular mesentérico. Essa massa foi removida através de uma enterectomia e realizou-se exame citológico e histopatológico diagnosticando um leiomioma. Após 19 dias o paciente recebeu alta e proprietário relatou ganho de peso e melhora na performance após a alta médica.(AU)
