Hemostasis technique using an adjustable nylon tie in dog with splenic hematoma and lymphoid hyperplasia

Background: Splenic hematoma is an encapsulated blood accumulation, which is macroscopically indistinguishable from malignant spleen. The treatment of choice and final diagnosis were by splenectomy and exploratory laparotomy followed by biopsy and histopathological examination, respectively. Nylon tie bands are devices made of polyamide 6.6, same material of surgical nylon wires, and has been used in different surgical procedures in animals. The present report case aimed to describe the use of nylon tie bands polyamide 6.6 in a 2.3-year-old Golden retriever dog diagnosed with splenic hematoma and lymphoid hyperplasia; and the clinical presentation, diagnostic evaluation, histological diagnosis of splenic hematoma and lymphoid hyperplasia. Case: A 2.3-year-old intact male Golden retriever dog was presented with history of anorexia, apathy, regurgitation and weight loss. During the physical examination was identified a mass in the left side of abdomen. The complete blood count (CBC), serum biochemistry, urinalysis, and thoracic radiographs were no alteration. Abdominal ultrasound revealed splenomegaly and heterogeneous hypoechoic structure. Splenectomy using an adjustable nylon ties polyamide 6.6 for hemostasis technique was performed during an exploratory laparotomy. The spleen presented hematoma and lymphoid hyperplasia at the histopathological examination, as well as the presence of siderocalcinotic plate in the trabecular spleen. The dog presented with no regurgitation, apathy or anorexia after 10 days of surgery. CBC, serum biochemistry analysis, thoracic radiographs and abdominal ultrasound revealed no abnormalities. Video laparoscopy did not showed any sign of adherence on the local where used the nylon tie bands. One year and three months after the surgery, the owner was contacted by telephone, since he had changed to other city, and he reported that the dog was healthy without any clinical signs...

Adenoma papilar cístico de tireoide em cão (Canis familiaris) / Thyroid papillary cist adenoma in dog (Canis familiaris)

Os adenomas da tireoide não são comuns em cães, sendo na maioria das vezes identificados na necropsia como um achado acidental. São neoplasias que acometem animais com idade entre 11 e 13 anos. O trabalho teve como objetivo relatar o tratamento cirúrgico, sem associação a nenhum tratamento adjuvante, de adenoma papilar cístico não funcional de tireoide, de 8 cm de comprimento e 6 cm de largura, em um cão da raça Labrador, com quatro anos de idade, atendido no Hospital Veterinário Escola, Moçambique. Os exames complementares de imagem (radiografia e ultrassonografia), hemograma, bioquímica sérica, dosagem hormonal e aspiração com agulha fina (CAAF), não foram conclusivos para o diagnóstico definitivo. Contudo, o exame histopatológico foi determinante para o diagnóstico definitivo, sendo que o tratamento por excisão cirúrgica completa, sem associação a quimioterapia, foi eficaz no presente caso.(AU)

The thyroid adenomas are not common in dogs, and the majority of cases are identified at necropsy as an accidental finding. These neoplasias affect dogs with age between 11 and 13 years old. The aim of this work was to report the surgical treatment, with no association to any adjuvant treatment, of non functional thyroid papillary cist adenoma with 8 cm in length and 6 cm in width, in a dog, Labrador breed, with four years old, attended at the Veterinary Hospital School, Mozambique. The complementary exams as image (X-ray and ultrasound), complete blood count, serum biochemistry, hormonal dosage and fine-needle aspiration (FNA), were not conclusive for the diagnosis. However, the histopathology exam was crucial for the definitive diagnosis, and the treatment by complete surgical resection, without association with chemotherapy, was effective in this case.(AU)

Linfoma digestivo em gato doméstico (Felis catus): relato de caso / Digestive lymphoma in domestic cat (Felis catus): Case report

This study aimed to describe a digestive lymphoma in a female cat with twelve years old, cross breed and negative for feline leukemia (FeLV) and feline immunodeficiency virus (FIV). During physical examination was observed a moderate dehydration and abdominal pain. During transabdominal ultrasound was observed a spleen size increase with anecogenic areas with moderate vascularization, suggestive for tumor. Histopathologic examination of tumor was spleen lymphoma - lymphoblastic lymphoma. Immunohistochemical examination classification was B lymphocytes cells tumor. Chemotherapy with vincristine sulphate and prednisone, followed by total splenectomy was performed. Animal demonstrated improvements after treatment and three months after was diagnosed a liver lymphoma and the owner asks for euthanasia. The present case report shows tnecessity of chemotherapy to control this type of tumor, to increase the quality and patient survival. Digestive lymphoma with high rate of mitosis can be observed in cat with over 10 years old without being associated with infection by FIV or FeLV.(AU)

O objetivo do trabalho foi descrever um caso de linfoma digestivo em uma gata de 12 anos de idade, sem raça definida, com sorologia negativa para leucemia felina (FeLV) e imunodeficiência felina (FIV). Durante o exame físico foi observado desidratação moderada e dor abdominal. No exame transabdominal ultrassonográfico foi observado esplenomegalia e áreas anecogênicas dispersas na região do corpo e cabeça esplênica, moderada vascularização, sendo sugestivo a neoplasia. A neoplasia foi classificada como linfoma esplênico, do tipo linfoma linfoblástico. O exame imunofenotípico, classificou o linfoma como linfoma das células B. A neoplasia foi tratada com quimioterapia combinada de sulfato de vincristina e prednisolona, seguida de esplenectomia total. O animal demonstrou melhorias após o tratamento, e três meses após foi diagnosticado linfoma hepático, e o proprietário optou pela eutanásia. Existe a necessidade da terapia antineoplásica no controle do linfoma digestivo, com o objetivo de aumentar a qualidade de vida e sobrevida do paciente. Foi possível observar o linfoma digestivo de grau alto e com alto índice de mitose, em uma gata com idade acima a 10 anos e sem associação à infecção por FIV ou FeLV.(AU)

Prolapso da glândula da terceira pálpebra em cão: relato de caso / Third eyelid gland prolapsed in dog: case report

Fazem-se necessárias atualizações na literatura a respeito do prolapso da glândula da terceira pálpebra, no que diz respeito ao seu tratamento, devido à existência de diferentes técnicas cirúrgicas para sua resolução, com vantagens e desvantagens. O trabalho relata o tratamento cirúrgico, utilizando a técnica de Moore, do prolapso da glândula da terceira pálpebra bilateral, em uma cadela com entrópio bilateral, seis meses de idade e da raça Shar-Pei, atendida no Hospital Veterinário Escola, Moçambique. A técnica de Moore apresentou um bom resultado, e em casos de presença de entrópio bilateral podem ser realizadas ambas as cirurgias no mesmo dia, desde que o entrópio não seja do tipo espástico. O procedimento cirúrgico usando a técnica de Moore continua sendo a técnica cirúrgica de fácil aprendizado, mais simples de se realizar e não afetou a mobilidade da terceira pálpebra.

The updating of the of the prolapse of the third eyelid gland treatment in the literature is pertinent, due to the different surgical techniques for his resolution, with advantages and disadvantages. The work aimed to report the Moore technique in surgical treatment of the bilateral prolapse of the third eye lidgland in a female dog with bilateral entropion, six months, Shar-Peibreed, attended in the Veterinary Hospital School, Mozambique. The Moore technique showed good results andif the bilateral entropionwas not a spastic type, wasable to do the both surgeries in same day. The surgery using the Moore technique continues easy to learn, more simple to do and does not affect the third eyelid mobility.
