Cisto ósseo aneurismático em tecido mole em um cão: relato de caso

ABSTRACT This paper describes the diagnosis and treatment of a dog with a rare aneurysmal bone cyst in soft tissue. The patient was attended in the Veterinary Clinic Hospital at the Fedral University of Rio Grande do Sul due to limited mobility, weakness in hind limbs, and dyschezia for 15 days. It was already receiving medical treatment without success. Upon clinical examination a solid increase volume in the right perineal region was detected, and complementary imaging tests were requested. Radiography of the region suggested right perineal hernia or neoplasia. The dog was submitted to surgery, and a rounded and ossified tumoral structure was removed. The histopathological exam diagnosed the structure as an aneurysmal bone cyst in soft tissue, and the patient recovered fully after surgical excision.

Implante de Port-o-Cath para quimioterapia antineoplásica em um canino: relato de caso

The Port-a-Cath is a totally implantable central venous catheter that allows the infusion of chemotherapeutic agents, blood products, parenteral nutrition, and blood sample collection. This work reports the case of a dog with a tumor in the pelvic limb that was treated surgically and received the catheter for cancer chemotherapy. The patient was diagnosed with synovial sarcoma, an uncommon tumor in dogs that usually affects the joints and requires multimodal therapy. The treatment was done in two steps, in the first the limb was amputated and in the second the Port-a-Cath implantation and the excision of the metastatic nodule were performed. The dog responded well to surgery and chemotherapy sessions held with proper functioning of the catheter, and died from other causes 90 days after the procedure. The implantation of Port-a-Cath for chemotherapy is a great ally of multimodal therapy recommended for cancer, so this catheter may be considered for patients requiring chemotherapy medication for a long period.

Agenesia renal unilateral e criptorquidismo ipsilateral em um felino: relato de caso

A agenesia renal e uma afeccao congenita rara na especie felina, frequentemente associada a uma malformacao reprodutiva. O presente trabalho relata o caso de um felino com agenesia renal unilateral associada a criptorquidismo ipsilateral, com enfase no diagnostico, tratamento e acompanhamento. O paciente foi conduzido ao Hospital de Clinicas Veterinarias da Universidade Federal do Rio Grande do Sul para avaliacao de criptorquidismo. A agenesia renal foi um achado durante a ecografia abdominal do felino. Durante a laparotomia, foi confirmada a ausencia do rim e ureter direito, hipertrofia do rim esquerdo e presenca de um testiculo ectopico. O paciente teve alta apos a recuperacao anestesica e se mantem clinicamente estavel, transcorridos seis meses da cirurgia. A agenesia renal unilateral e uma condicao compativel com a vida, contanto que o rim existente apresente funcionamento aceitavel. Assim, sugere-se que a possibilidade de rim unico em felinos criptorquidas deve ser investigada sempre que possivel, tendo em vista a alta correlacao entre essas malformacoes, e objetivando um acompanhamento da funcao renal do paciente ao longo da vida.
