Beating heart partial ventriculectomy in dogs

After valve endocardiosis, dilated cardiomyopathy is the most diagnosed cardiac affection in dogs. Sometimes this disease is unresponsible to medical therapy, in this way surgery becomes necessary to its correction. Unfortunately, dogs do not support cardiopulmonary bypass because its tendency in microtrombus formation in the capillary vessels of the lung circulation. Due to this condition, another surgical alternatives were developed, in order to correct the increase in ventricle size, as the ventricle plication or partial ventriculectomy with the inflow occlusion. However, this kind of technique has its complications, as well the ventricle plication. In plication, a part of necrotic heart tissue still remains, and if the necrosis does not happen, that portion of myocardium keeps its oxygen consumption, leading to heart failure. The partial ventriculectomy with the inflow occlusion is time dependent. For its execution it means that the surgeon gets only four minutes to perform the resection of the dilated ventricle and then suture the remaining defect after the inflow occlusion. The aim of this study is to develop a new technique of heart size reduction, called by the authors Beating Heart Partial Ventriculectomy

Condrossarcoma mixóide em um coelho

Tumores ósseos primários em animais, com exceção dos osteossarcomas, são raros. O condrossarcoma é uma neoplasia maligna, de crescimento lento, proveniente de tecido cartilaginoso. É um tumor localmente invasivo, tendo grande propensão a recidivas, mas baixa incidência de formação de metástases. O diagnóstico definitivo é dado pelo exame histopatológico. A remoção cirúrgica, com obediência aos preceitos da cirurgia oncológica é o tratamento indicado. Foi atendido, no Hospital de Clínicas Veterinárias da Universidade Federal do Rio Grande do Sul, um coelho, sem raça definida (SRD), macho, não castrado, com aproximadamente três anos de idade e 4,3kg de peso, apresentando claudicação e aumento de volume na região distal do membro pélvico direito. O exame histopatológico revelou diagnóstico de condrossarcoma mixóide de grau II. Realizou-se a amputação do membro afetado. O paciente demonstrou uma boa recuperação dos movimentos nos primeiros dias após a cirurgia, retornando às funções que realizava anteriormente, como caminhar, correr e saltar

Tibiotarsus osteosynthesis' in blue-yellow-macaw (Ara ararauna) using titanium miniplate

Among the surgical problems of birds, fractures are the most prevalent, and the long bones of the wings and pelvic limbs are the most frequently affected. The success of orthopedic surgery in birds is directly related to the techniques used to undo the mechanical forces of a fracture. At the veterinary teaching hospital a psitacid from the Ara ararauna (blue-and-yellow-macaw) species with a clinical history of trauma in the cage was treated. Craniocaudal and lateral radiographs of the left limb demonstrated a mid-diaphyseal fracture of the tibiotarsus. The bird was sent to surgery. The patient was anesthetized with isufluorane and for the pre-anesthesic medicacion methadone was administrated. A medial surgical approach to the tibiotarsus was made and fracture reduction was performed. The fracture was stabilized through a titanium miniplate (system 2mm) fixed medially on the tibiotarsus with 6 cortical miniscrews, being 3 proximal and 3 distal to the fracture site. In this case, there was no complication in placing the miniplate and miniscrews, resulting in a satisfactory alignment of the fragments and causing an efficient reduction of the diaphyseal fracture of tibiotarsus with functional return of the limb and bone consolidation

Prolapso uretral em um bulldogue inglês

O prolapso uretral é incomum em cães, e se caracteriza pela protusão da mucosa uretral além da extremidade do pênis. O presente relato descreve o caso de um cão, Bulldogue Inglês, 6 meses de idade, atendido no Hospital de Clínicas Veterinárias da Universidade Federal do Rio Grande do Sul (HCV-UFRGS) com histórico de sangramento prepucial. Ao exame físico, o animal apresentou aumento de volume da glande do pênis, de coloração avermelhada e presença de hemorragia local. Descartadas quaisquer outras patologias, confirmou-se o prolapso uretral. Encaminhado para cirurgia, realizou-se ressecção da porção uretral prolapsada e posterior sutura da mucosa uretral no epitélio peniano. Passados 15 dias do procedimento cirúrgico, o animal retornou para revisão onde foi evidenciada completa cicatrização uretral.Urethral prolapse is uncommon in dogs and it is characterized by the prolapse of the urethral mucosa farther penile border. The present story describes a case of a dog, English Bulldog, 6 month old, taken care in HCV-UFRGS with history of preputial hemorrhage. At physical examination, the animal presented with enlarging of penile acorn, red coloured and local hemorrhagy. Dismissed others pathologies, prolapse urethral was confirmed. Leading for surgery, the resection of everted urethra was realized, with posterior syntesis of urethral mucosa at penile ephithelium. After 15 days of surgery, revision was done where complete utrethral healing was evident
