“…The uterine torsion is an uncommon condition in cats and may be associated with the final third period of gestation (THILAGAR et al, 2011). The clinical presentation occurs with clinical signs of acute abdomen (DE LA PUERTA et al, 2008), as was observed in this case, where the animal came to the veterinary hospital presenting abdominal distension and pain.…”

“…The haematological tests showed severe normocytic and normochromic anemia compatible with blood loss, which may be related to the large volume of blood in the uterus and vascular stasis of uterine vessels due to torsion (RIDYARD et al, 2000;THILAGAR et al, 2011). Furthermore, the blood loss due to the shock syndrome was already established preoperatively.…”

“…The clinical signs and hemodynamic changes of this condition are directly proportional to the torsion degree, which can vary between 180 and 900° both clockwise and counterclockwise, this parameter being considered as an indicator of prognosis (THILAGAR et al, 2011).…”

“…Uterine torsion is defined as rotation of one or two uterine horns, or the entire uterus about its longitudinal axis; and is more commonly observed in multiparous females (THILAGAR et al, 2011). Its etiology is unknown, but may be associated with the broad ligament laxity of the uterus; fetal movements; uterine contractions; presence of flaccid uterine walls or long/sagging mesometrium, or even the small amount of fetal fluids; obstetric maneuvers during dystocia and excessive physical activity during pregnancy (STONE, 2007).…”

SUMMARYUterine torsion is defined as a rotation of more than 45° around the longitudinal axis of one or both uterine horns more commonly observed in multiparous females. Nonspecific clinical signs generally reflect abdominal pain. Diagnosis is confirmed by exploratory celiotomy. Surgical treatment is urgent and should be performed as soon as possible. This assay reports the uterine torsion diagnosed in an 11-year-old mixed breed cat. The patient was referred with severe lethargy, hypothermia, abdominal pain and bloody vaginal discharge. Its mucous membranes were pale and dry, the extremities were cold, estimated dehydration was 10% and peripheral pulse was not palpable. The patient also had bloating and abdominal tenderness. The ultrasound exam revealed the presence of fetuses without heartbeat and a small amount of free liquid in the abdominal cavity. The patient was referred for ovariohysterectomy surgery after emergency treatment. The resection in bloc technique was performed removing both ovaries and uterus. Despite the intensive care, the animal did not recover and died hours later.KEY WORDS: Acute abdomen. Pregnancy. Ovariohysterectomy. Septic shock. RESUMOA torção uterina é definida como a rotação de um ou dois cornos uterinos, ou ainda de todo o útero, sobre seu eixo longitudinal, sendo mais frequente em fêmeas multíparas. Os sinais clínicos são inespecíficos e, em geral, refletem dor abdominal, sendo o diagnóstico definitivo mais frequentemente realizado por meio de celiotomia exploratória. O tratamento dessa afecção é cirúrgico, devendo ser realizado o mais breve possível. O presente relato descreve um caso de torção uterina em um felino doméstico, sem raça definida e 11 anos de idade, que apresentava intensa letargia, hipotermia, extremidades frias, mucosas pálidas e secas, desidratação estimada em 10%, distensão abdominal e algia à palpação, pulso periférico não palpável e secreção vaginal de coloração sanguinolenta. Na ultrassonografia abdominal foi observada presença de fetos, ausência de batimentos cardíacos fetais e pequena quantidade de líquido livre na cavidade. Após estabilização do quadro clínico, a paciente foi encaminhada para cirurgia de ovariosalpingohisterectomia. O procedimento foi realizado sem desfazer a torção uterina, com o útero e ovários sendo removidos em bloco. O animal ficou sob cuidados intensivos, porém foi a óbito quatro horas após a intervenção cirúrgica. PALAVRAS-CHAVE:Abdômen agudo. Endotoxemia. Gestação. Ovariosalpingohisterectomia.

“…Both uterine and ovarian torsions are uncommon in veterinary medicine, particularly in small animals [8,12,14]. Previous reports described ovary torsion in pregnant and non-pregnant female cats [11,12,16,17]. Misumi et al [14], Darvelid and Linde--Forsberg [2] reported higher ovarian torsion incidence in pregnant female dogs than in non-pregnant ones.…”

Background: Ovarian torsion is a condition which the ovary and the ovarian pedicle twist around the ovary suspensory ligament. No report regarding this condition was reported. The aim of the report was to describe a case of unilateral ovarian torsion in a 2-year-old primipara Golden Retriever dog.Case: A 2-year-old female primipara Golden Retriever dog weighting was referred to the Veterinary Hospital, for purulent vaginal discharge evaluation. The dog was presenting anorexia, weight loss, and intermittent diarrhea and vomiting. A cesarean section was performed nine months before her presentation and the oestrus cycle was recorded six months after the cesarean section. Discomfort was observed during the palpation of the abdomen and purulent vaginal was observed. Vaginal swab was performed and followed by cytological examination. The ultrasonographic examination was consistent with pyometra. The ovariohysterectomy was performed and were observed torsion of the left ovary. The histopathological examination of the left ovary and uterus were consistent with ovary necrosis and pyometra. Ten days after surgery the vaginal discharge had resolved and the sutures were removed. Six months postoperatively the dog revealed no further abnormalities. Grossly, the left ovary had firm consistency, dark red surface and 8 cm diameter. The histopathology examination findings were consistent with a diagnosis of diffuse necrosis of left ovary due to ovarian torsion, and uterinesuppurative inflammatory process - pyometra.Discussion: Ovarian torsion is uncommon in small animals, but can be observed high incidence in pregnant female dogs than in non-pregnant ones. The 360º an asynchronous ovarian torsion described in the present case is also an unusual condition in primipara female dogs due to the smaller stretching of the ovary suspensory ligament. The ovarian torsionis considerate an emergency condition due to acute abdominal pain. The mild abdominal discomfort observed during the physical examination was associated to pyometra or to ovarian torsion. The histopathological findings as hemorrhage, edema and necrosis were associated to compromised arterial circulation and ovarian torsion in late stage. The size of the pregnant uterus and/or the pyometra has contributed to ovary torsion. The dog of the present report had pyometra and previouscesarean sections; and these conditions may have contributed to ovarian torsion. The condition was incidentally found during the ovariohysterectomy, and the ovarian torsion diagnosis was determinate through histopathological examination. Computed tomography and magnetic resonance image could be used to diagnose, furthermore, they were not conducted due to the high cost. The leukocytosis and red blood cells Rouleaux was associated with ovarian necrosis and pyometra.Ovariohysterectomy was the treatment of choice to pyometra and ovarian torsion, and the surgery was performed without ovarian torsion reversion to minimize the reperfusion lesions. Ovarian torsion is a rare event in dogs, and it was clinically diagnosed during the surgery. To the best of the authors’ knowledge, this is the first report of ovarian torsion associate withpyometra in primipara female dogs in Brazil.Keywords: dog, obstetric, ovary, pyometra complex, endometrium.
