Laparoscopia diagnóstica em c?es: análise de 27 casos
SCHOSSLER, Joo Eduardo;
Brazilian Journal of Veterinary Research and Animal Science , 1998, DOI: 10.1590/S1413-95961998000300006
Abstract: laparoscopy was used for the visualization of abdominal viscera of 27 dogs afflicted with different pathologies. in all cases general anesthesia was applied. an incision was made on the ventral midline approximately 1cm caudal to the navel. at this point a trocar was introduced for the production of pneumoperitoneum. after that, the optical probe was introduced for inspection of the abdominal cavity. the different organs were visually identified by their external morphology. moreover, the exam also allowed the identification of different pathologies. in two cases of splenic and pancreatic atrophy, as well as in case of hepatic necrosis the laparoscopic examination was instrumental for the understanding of the disease, leading to a final diagnostic confirmed by histopathological analysis. the presence of hepato-frenic adhesion was immediately identified in one case, helping in the planning of corrective surgery. cases of piometritis in initial stages were identified thanks to the laparoscopic exam, since biochemical and radiological data was highly inconclusive. the laparoscopy determined the impossibility of surgical removal of two hepatic tumors and one case of intestinal neoplasia. the results most likely influenced the request for euthanasia by the owners. the present observations agree with citations in which laparoscopy cannot avoid major surgery, however it gives valuable information regarding the conditions of the tissues and the extension of the lesions.

Abstract: the traumatic coxofemoral luxations are important orthopedics injuries in dogs and cats due to their great frequency. the main causes are the automobilistic accidents and craniodorsal appearance is the most frequent. this injury can affect any breed, sex and age, however, adult animals are most frequently involved. close reduction is the first choice of treatment, but at some circumstances the use of open/surgical methods are necessary. this study aims to evaluate the incidence, predisposition, etiology and results of treatments of traumatic hip luxation at the santa maria federal university veterinary hospital. for this, a retrospective study of surgical service was made between 1997 and 2006 in this hospital. it was observed a high incidence of traumatic luxations (75.8%), and the most frequent cause was hit t by a car trauma (58.6%), followed by falls (17.3%), unknown agents (17.2%) and fights (6.9%). the canine/feline proportion was 58/2, with the males being the most affected in both species: 65.5% at dogs and 100% at cats. the most predicts breed involved was the poodle (44.8%) and the mixed breed dogs (20.7%). the treatments options used were suture of capsule (18.3%), transacetabular pinnig (56.7%) and femoral head and neck excision (25%). the success rate was 71.1% in the first two techniques, proving itself efficient in the traumatic coxofemoral luxation reduction, thus, femoral head and neck excision are recommended in complications and impossibility.

Abstract: in this study we evaluate the contribution of external skeletal fixation devices and intramedullary pins in the functional recovery of healthy dogs. sixteen healthy dogs have been divided into two experimental groups of 8 dogs each. the first group was submitted to external skeletal fixation devices and the second group was submitted to intramedullary pins in the left tibia. the external skeletal fixation was taken out by the thirtieth day of the clinical evaluation. the dogs that were submitted to external fixation devices had functional recovery of the studied limb of 17.3 days (in average), while those submitted to intramedullary pins had the functional recovery of the limb in 4.2 days. we concluded that the intramedullary pins have less interference in the functional recovery of the affected limb when compared to the external skeletal fixation devices.

Abstract: in this study, 10 clinically healthy adult mongrel dogs were submitted to the temporary immobilization of the hock with external skeletal fixation. the aim of this procedure was to evaluate, using a manual goniometer, the flexion, the extension and the range of motion of the tarsocrural joint after immobilization in a functional angle of 135o for 45 days. the animals presented discomfort in relation to the articular manipulation for the goniometric exam on the day of the removal of the apparatus, demonstrating pain in the passive flexion and extension of the limb, and such difficulty disappeared after three days. it was observed that the temporary immobilization of the articulation obtained by the external skeletal fixation promotes statistically significant loss in the degree of flexion, extension and range of motion of the tarsocrural joint immediately after the removal of the apparatus. however, after seven days of this removal, for extension, and fifteen days, for flexion and range of motion of the articulation, this loss is not verified.

Acta Cirurgica Brasileira , 1999,
Abstract: Neste experimento foram utilizados 15 animais, 11 caninos e 4 felinos, portadores de fratura distal de tíbia, tratados pela imobiliza o tíbio-tarsal com um fixador externo. O aparelho na maioria dos casos apresentou uma configura o consistindo de dois pinos na por o proximal da tíbia, um ou dois no calcaneo e um ou dois pinos nos metatarsianos, todos conectados externamente por uma barra de acrílico autopolimerizante. O aparelho foi removido em média aos 45 dias de pós-operatório, quando foi observado radiograficamente o desaparecimento da linha de fratura óssea. Quatorze animais (93,3%) tiveram recupera o funcional total do membro operado, com perfeita deambula o, uma semana após a remo o do fixador. Diante dos resultados obtidos, pode-se afirmar que a técnica é eficaz na corre o de fraturas distais de tíbia, inclusive as expostas.

Abstract: Avalia-se, clínica e comparativamente, o aparelho de fixa o externa e pinos intramedulares, quanto ao tempo de recupera o das fun es normais e deambula o de c es sadios. Foram utilizados 16 c es sadios separados em dois grupos experimentais de oito animais. No primeiro grupo, os c es foram submetidos à aplica o de um aparelho de fixa o externa e, no segundo grupo, submetidos à inser o de dois pinos intramedulares na tíbia esquerda. Os aparelhos de fixa o externa foram retirados após 30 dias de avalia o clínica. Observou-se que os c es com fixadores externos tiveram retorno funcional em média de 17,3 dias, enquanto os submetidos à inser o intramedular tiveram retorno aos 4,2 dias. Com esses resultados, conclui-se que o uso de pinos intramedulares tem menor interferência na deambula o em rela o ao aparelho de fixa o externa.

Abstract: Neste experimento, foram utilizados 10 c es clinicamente sadios, submetidos à imobiliza o temporária das articula es tíbio-tarsal, intertarsal e tarso-metatarsiana direita com fixador esquelético externo, tendo por objetivo avaliar através da mensura o da flex o, da extens o e da amplitude articular os danos provocados por esta imobiliza o. O aparelho de fixa o esquelética externa manteve a articula o em um angulo aproximado de 135masculine e permaneceu por 45 dias. Os animais apresentaram desconforto à manipula o articular para a realiza o do exame goniométrico no dia da retirada do aparelho, demonstrando dor na flex o e na extens o passiva do membro imobilizado, sendo que tal dificuldade desapareceu após três dias. Foi observado que a imobiliza o articular temporária obtida pela fixa o esquelética externa promove perda estatisticamente significativa nos graus de flex o, de extens o e de amplitude articular tíbio-tarsal imediatamente após a remo o do fixador externo. Porém, após sete dias desta remo o para extens o e quinze dias para flex o e amplitude articular, esta perda n o é mais verificada.
