Torção esplênica primária em cão como causa atípica de abdômen agudo / Primary splenic torsion in dog as a cause of atypical acute abdomen

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)

Uso de enxerto autógeno de fáscia lata no tratamento de defeito segmentar crônico do tendão calcâneo comum em felino doméstico / Use of autogenous fascia lata graft in the treatment of chronic segmental defect of the common calcaneus tendon in domestic feline

Background: The common calcaneus tendon is formed by the common tendon of the femoral biceps muscle, tendon of the superficial digital flexor muscle and gastrocnemius muscle tendon, and its rupture is related to acute traumas in small animals. Among some applications described, surgical repair can be adopted in the correction of tendon ruptures and the use of grafts may be indicated in some severe lesions, where it is not possible to perform tenorrhaphy. This study aims to report the case of a feline with rupture of the common calcaneus tendon in which the tenorrafia associated with the autogenous fascia lata graft was performed as adjuvant to the cicatrization of the same.Case: A 24-month-old, undefined male feline with approximately 3 kg was treated at the FCAV Veterinary Hospital, UNESP Jaboticabal, State of São Paulo, Brazil, with a history of falling, for approximately two weeks, and has since plantigrade posture. Upon physical examination, it was possible to identify a discontinuity of the common calcaneus tendon. The radiographs were performed, which did not show any bone changes. A hemogram and biochemical profile were performed, which were within normal limits. The patient underwent surgery, and a complete lesion of the common calcaneus tendon was identified, with a chronic aspect. Approximation of the stumps was impossible, so a flap of fascia lata, about two centimeters long and one centimeter wide, was removed, which was used as a bed and tendon support for tendon growth. After removal all of the present fibrosis, the tendon stumps were approximated by means of modified Kessler suture with mononylon thread, and fascia lata flap of the ipsilateral limb was sutured with separate single points in both tendon ends and in their lateral and medial portion. In the tibiotarsic joint, the external skeletal fixator type II was used for immobilization, during a period of 30 days.[...]
