Ectopia ureteral unilateral congênita em uma cadela Teckel Dachshund com pelagem arlequim: relato de caso / Single congenital ureteral ectopy in a female dog Teckel Dachshund with merle colour pattern: case report

O presente relato apresenta a primeira descrição de ectopia ureteral congênita na raça Teckel Dachshund, diagnosticada em uma cadela com pelagem arlequim. O animal, aos dois meses de idade, apresentava sinais de incontinência urinária e cistite bacteriana, sendo submetido a um plano diagnóstico para confirmação de ureter ectópico. A urografia excretora revelou hidroureter direito com desembocadura caudal ao trígono da bexiga. O exame físico do animal evidenciou ainda hérnia inguinal bilateral, o que reforçou a caracterização da origem congênita das alterações. Aspectos de bem-estar animal são também discutidos.

The present work reports the first description of congenital ureteral ectopy in the canine breed Teckel Dachshund, diagnosed in a female dog with merle colour pattern. The two month old animal, presented with continuous dribbling of urine and bacterial cystitis, was subjected to a diagnostic plan for ectopic ureter. The excretory urography showed a right hidroureter, which had an orifice located caudally to the trigone of the bladder. The animal also presented a bilateral inguinal hernia, which confirmed the case description as a multiple congenital anomaly condition. Animal welfare aspects are also discussed.

Pós-operatório tardio da substituição do ligamento cruzado cranial no cão / Late postoperative of cranial cruciate ligament replacement in dog

Realizaram-se avaliações radiográfica e clínica pós-cirúrgica tardia da substituição do ligamento cruzado cranial (LCCr) por fáscia lata autógena em casos de ruptura clínica em 14 cães, de ambos os sexos, com massa corporal média de 28,6kg e idade média de 68 meses. As articulações tratadas constituíram o grupo tratado e as contralaterais o grupo-controle, totalizando 28 articulações estudadas. O tempo médio entre o aparecimento dos sintomas e a cirurgia foi de cinco meses e 15 dias e o decorrido entre a cirurgia e a avaliação pós-cirúrgica, 14 meses. Deambulação normal foi vista em 57,1 por cento e claudicação discreta em 32,9 por cento dos casos tratados. Nestes foram observados crepitação, dor, redução da amplitude de movimento articular e do diâmetro da coxa. Ausência de claudicação foi vista em 92,8 por cento dos casos-controle. Doença articular degenerativa foi verificada radiograficamente nos dois grupos. A técnica empregada para substituição do LCCr foi efetiva clinicamente. Os resultados radiográficos, as vezes, mostravam-se diferente dos clínicos. O resultado foi melhor nos pacientes cuja cirurgia foi realizada após curto período do inicio dos sintomas e o intervalo entre a lesão e o tratamento foi o fator que mais influenciou na recuperação pós-operatória

After the replacement of the cranial cruciate ligament (CrCL) with an autogenous fascia lata graft, radiographic and clinic post-surgical evaluation were performed. Fourteen male and female dogs averaging 68 month-old and 28.6kg body weight with unilateral rupture of CrCL were selected. Twenty-eight joints were studied. The treated joints consisted of the treated and non-treated animals. The mean time from the initial onset of the symptoms to the surgery was five months and 15 days and the mean interval between the surgery and the follow-up examination was 14 months. No lameness was observed in 57.1 percent of the treated dogs and mild lameness in 42.9 percent of them. In this group, articular crepitus, pain, reduced articular motion amplitude and muscular atrophy were observed. No lameness was observed in 98.2 percent of the non-treated dogs. These joints showed mild arthrosis. Degenerative joint disease was observed in both groups. The surgical technique was efficient, the dogs showed clinical improvement after surgery, regardless of radiographic signs. The results were better in the dogs submitted to surgery soon after the onset of the symptoms. The interval between the injury and the treatment was the most important factor involved in the recovering after surgery

Avaliação pós-operatória da fixação esquelética externa em 29 cães: estudo retrospectivo / Post surgical evaluation of external skeletal fixation in 29 dogs: a retrospective study

In this retrospective study 29 dogs of both sexes of several breeds, were evaluated. Complications of external skeletal fixation were common. The most frequent post-surgical complications were chronic pin track drainage or pin loosing (11; 37.9 percent), followed by dry crust at the skin-to-pin interface (5; 17.1 percent). In five cases (17.1 percent) occurred the healing of the fracture without complications. In three dogs (10.4 percent) occurred nonunion and it was used another fixation method. It was observed individual cases of poor limb use (3.5 percent) or breakage of the pin (3.5 percent) or of the acrylic column (3.5 percent). Pin track drainage or loosing was related to the owners care. The most did not come back to the hospital as was demanded or did not follow the instructions to inspect the apparatus daily. This behaviour contributed to increase the rate of post-surgical complications. The external fixation has the advantage to be less invasive and can be used to treat closed and open fractures, limb deformities, nonunion and infected fractures.
