Clinical and epidemiological findings of cecal disorders in horses in the state of Paraíba / Achados clínicos e epidemiológicos dos distúrbios cecais em cavalos no estado da Paraíba

This was a retrospective case study of colic syndrome of cecal origin in 159 horses treated at a reference Veterinary Center between June 2015 and July 2021. The data studied were breed, age, sex, clinical examinations of the initial emergency care, treatment protocols (clinical and/or surgical) and resolution (hospital discharge, euthanasia or death). It was observed that 7.55% (n = 12) of the cases corresponded to colic syndrome of cecal origin, where 75% (n = 9) had heart rate within the physiological range for the species, as well as 50% (n = 6) for capillary refill time values, 33.33% (n = 4) for pink mucosa, 41.67% (n = 5) for rectal temperature, and 16.67% (n = 2) on abdominal auscultation. In 58.34% (n = 7) of patients, pain could be controlled with analgesics, with recurrence in 41.67% (n = 5). All treated cases were cecal impaction, where 58.33% (n = 7) ruptured the cecum. In 75% (n = 9) of the cases, surgical treatment was performed. Regarding the general resolution of cases, 41.67% (n = 5) of the animals were discharged. Therefore, it is concluded that despite the increase in the diagnosis of colic of cecal origin, this disease is still rare (7.55%) and has a high potential for death since there are few clinical alterations, making its early diagnosis difficult.(AU)

Este foi um estudo retrospectivo dos casos de síndrome cólica de origem cecal em 159 cavalos atendidos em um Centro Veterinário de referência entre junho de 2015 e julho de 2021. Os dados estudados foram raça, idade, sexo, exames clínicos do atendimento inicial de emergência, protocolos de tratamento (clínico e/ou cirúrgica) e resolução (alta hospitalar, eutanásia ou óbito). Observou-se que 7,55% (n = 12) dos casos correspondiam à síndrome cólica de origem cecal, onde 75% (n = 9) apresentavam frequência cardíaca dentro da faixa fisiológica para a espécie, assim como 50% (n = 6) para valores de tempo de enchimento capilar, 33,33% (n = 4) para mucosa rosada, 41,67% (n = 5) para temperatura retal e 16,67% (n = 2) para ausculta abdominal. Em 58,34% (n = 7) dos pacientes, a dor pôde ser controlada com analgésicos, com recidiva em 41,67% (n = 5). Todos os casos tratados foram de impactação cecal, onde 58,33% (n = 7) romperam o ceco. Em 75% (n = 9) dos casos, o tratamento cirúrgico foi realizado. Em relação à resolução geral dos casos, 41,67% (n = 5) dos animais tiveram alta. Portanto, conclui-se que apesar do aumento do diagnóstico de cólica de origem cecal, esta enfermidade ainda é rara (7,55%) e apresenta um alto potencial de óbito visto que há poucas alterações clínicas dificultando seu diagnóstico precoce.(AU)

Ruptura bilateral do músculo fibular terceiro em bovino / Bilateral rupture of the peroneus tertius muscle in bovine

Background: The peroneus tertius muscle is responsible for tarsal flexion and coordinate extension of the stifle joint. The most common causes of rupture are excessive effort when trying to rise on a slippery surface, mounting, or being mounted. Rupture of the peroneus tertius muscle is characterized by an inability to flex the hock. Most cases are not curable, presenting an unfavorable to poor prognosis, and the animal has to be euthanized. This study aimed to report the clinical picture and treatment of a bilateral rupture of the peroneus tertius muscle in a cow from the municipality of Castanhal, state of Pará (Amazonian biome). Case: We report the clinical picture and treatment of a bilateral rupture of the peroneus tertius muscle in a 4-year-old cow, mixed breed, weighing approximately 400 kg, calved 3 months ago, belonging to a batch of 40 cattle kept on extensive breeding system in a pasture of Urochloa (Brachiaria) brizantha. The clinical signs appeared after the cow was mounted by a 1,100 kg bull and consisted of lameness, falling into sternal decubitus with hind limbs extended backward, hyperextension of the hocks with flexed stifle, with the tibia and metatarsus in a straight line, which lead to a 90-degree position of the femur and knee. Abrasions in the dorsal region of the fetlocks reinforce evidence of dragging hooves. Diagnosis of bilateral rupture of the peroneus tertius muscle was performed by a clinical examination and semiological test. Nonsteroidal anti-inflammatory drugs (flunixin meglumine, 2,2 mg/kg, every 24 h for 4 days) were prescribed for treatment, in addition to resting in a paddock with good availability of pasture, water, and mineral salt. After 3 months, we observed an improvement of the clinical signs, and after 6 months, an almost complete recovery. Only a slight difficulty in flexing the hock when moving remained. Discussion: In the present report, bull mounting was the probable cause of the hyperextension of both hocks and the bilateral rupture of the peroneus tertius muscle. According to the handler, these clinical signs were only evidenced after the animal was mounted. As stated in the literature, accidents such as falls, slips, mounting or being mounted, as well as excessive traction and over-elevation of the limb are considered predisposing factors for the onset of the disease. Rupture of the peroneus tertius muscle is unusual in production animals; therefore, the low occurrence of reports on this kind of rupture in the literature makes this case even more unique. The bilateral injury differs from cases described in the literature, in which the reported injuries were always unilateral. Our findings reinforce the hypothesis that the act of mounting was the triggering factor for the bilateral rupture of the animal peroneus tertius muscle. The breeding system also differs from the cases diagnosed by the same authors, since they describe the disease in bovines kept on intensive or semi-intensive breeding. In the present case, the cattle were kept on an extensive breeding system. The extension and flexion tests used in the clinical examination allowed for the diagnosis of rupture of the peroneus tertius muscle in both limbs, similarly to what has been reported by other authors. Anamnesis, clinical findings, and exclusion of different diagnoses were decisive for establishing the diagnosis. The treatment chosen was efficient, even though the case was severe, as the injury occurred in both hind limbs.

Prepubic tendon rupture in Santa Inês ewe: case report / Desmorrexia pré-púbica em ovelha Santa Inês: relato de caso

Prepubic tendon rupture may lead to the loss of pelvic floor support. A four-year-old Santa Inês ewe had been reported suffering from apathy, progressive weight loss throughout ten days, and prolonged pregnancy. Physical exams showed an excessive pendulous abdomen, a mild ventral edema between the udder and the umbilical scar (xiphoid region). Also, the udder was cranially displaced and with hematomas. Other symptoms noticed were walking reluctance, pelvic asymmetry, tachycardia, and tachypnea. The urinalysis findings indicated the presence of ketone bodies. The ultrasound examination confirmed the presence of fetuses with normal development, and a potential rupture of the abdominal muscles was excluded. Eight days following its hospitalization, labor induction was carried out using dexamethasone (20mg, IM, single application). She went into labor three days after the initial dose of corticosteroid. The ewe had difficulty expelling the lambs, making their traction necessary. Although the animal has recovered from its injuries, the clinical picture shows prepubic tendon rupture, and in order to prevent future complications, the ewe is not going to breed anymore. The report of this case works as an alert to the possibility of the occurrence of this affection in ewes and demonstrates the need of parturition assistance in animals with this condition, which can be diagnosed through clinical evaluation and ultrasound examination.

A ruptura do tendão pré-púbico resulta na perda do suporte do assoalho abdominal do animal. Uma ovelha, prenhe, da raça Santa Inês, de quatro anos, foi atendida com apatia e emagrecimento progressivo há dez dias e prolongamento da gestação. Ao exame clínico, verificou-se abdômen demasiadamente penduloso, discreto edema ventral entre o úbere e a região xifóide, úbere penduloso e com feridas, dificuldade de locomoção, assimetria de pelve, taquicardia e taquipneia. Detectou-se, na urinálise presença de corpos cetônicos. Foi confirmada à ultrassonografia, a viabilidade dos fetos. O parto foi induzido após oito dias de internação. Após três dias da aplicação do corticoide a ovelha entrou em trabalho de parto, sendo necessárias manobras obstétricas para retirada dos fetos, pois a mesma não apresentava contrações abdominais. O paciente se recuperou, mas como o quadro clínico era compatível com ruptura do tendão prépúbico, foi recomendado a retirada do animal da reprodução para evitar problemas futuros à ovelha e aos cordeiros. Conclui-se que o acompanhamento gestacional é indispensável para animais com esta afecção e que mediante avaliação clínica e ultrassonografia, pode-se chegar ao diagnóstico dessa afecção.

Neouretra com enxerto autógeno de segmento intestinal vascularizado em felino / Autogenous vascularized intestinal grafting for urethral reconstruction in feline

Background: Serious urethral damage or recurrent obstructions in felines require a urethrostomy to provide a return to and maintenance of urinary flow. In some cases, urethral reconstruction with complementary tissue is required. Grafting of autogenous vascularized intestinal segments is widely used in human medicine to promote the functional restoration of the urethra, but in veterinary medicine, its use is still incipient. Thus, the aim of this report was to analyze and describe the use of thein functional urethral repair in a feline diagnosed with a severe urethral rupture. Case: A castrated male cat presented with urethral obstruction. Emergency decompression cystocentesis was performed, and fluids and analgesics were administered. Catheterization and urohydropropulsion were attempted to relieve the obstruction, without success. An emergency perineal urethrostomy was indicated. After the procedure, the diagnosis (obstructive lower tract urinary disease) and the infeasibility of restoring urinary flow by conventional urethrostomy techniques were confirmed. We opted for a laparoscopic-assisted prepubic urethrostomy; the pre-prostatic urethra was transected, and its caudais end was brought through an abdominal incision cranially. However, urethral tension was noted after this maneuver was performed. Thus, we decided to use autogenous vascularized intestinal segment grafting for urethral reconstruction. A segment of the ileum was prepared for grafting, with preservation of irrigation and mesenteric innervation. A terminoterminal anastomosis was performed on the stumps of the remaining intestine, and the mesentery was sutured. The ileal graft was isolated and washed to remove...

Epidemiological and pathological aspects of noninfectious diseases of the gastrointestinal tract in 114 horses in Southern Brazil / Aspectos epidemiológicos e patológicos de doenças não infecciosas do trato gastrointestinal de 114 equinos no sul do Brasil

Equine colic is one of the most common cause of death in horses, but few studies have investigated specifically the conditions at the necropsy. This study aimed to describe the epidemiological and pathological features of noninfectious diseases of the gastrointestinal tract in horses. A retrospective study was conducted in search of cases of these diseases affecting horses from 2005 to 2017. During this period, 114 horses died of noninfectious diseases of the gastrointestinal tract, and the main causes were: primary gastric dilation (27/114), volvulus (27/114), enterolithiasis (20/114), rectal (colonic) perforation (15/114), gastric or cecocolonic impaction (10/114), incarcerations (6/114), intussusception (4/114), and others (5/114). Mixed breeds horses (56/114) and males (69/114) were mostly affected. The horses had a median and mean age of 10 and 10.9-years old, respectively. Primary gastric dilation was characterized by distension of the stomach by moderate to large amounts of content, which in 21 cases caused tearing of the stomach wall at the greater curvature (peritonitis), and the main predisposing factor was alimentary overload (17/27). Intestinal volvulus occurred within the small intestine (14 cases) and within the large intestines (13 cases). Grossly, there was intestinal ischemia with reddened to deep-black serosa and diffusely red mucosae. Enterolithiasis caused partial or complete obstruction of the right dorsal colon (9/20), transverse colon (4/20), small colon and right dorsal colon (3/20), rectum and right dorsal colon (2/20), and small colon (2/20). Viscera perforation and peritonitis occurred in 11 cases. Rectal (colonic) perforation involved the rectum (10/15), rectum/small colon (4/15), and the small colon (1/15). It was characterized by a focally extensive transmural tearing, associated with reddened borders, and retroperitoneal to diffuse peritonitis. Palpation related iatrogenic injuries (11/15) were the main cause. Impactions affected the large colon (7/10), the cecum (2/10), and the stomach (1/10). Incarcerations consisted of inguinoscrotal hernias (2/6), small intestine entrapment by a mesenteric failure (2/6), diaphragmatic hernia, and umbilical eventration. Grossly, the organs were constricted by a hernial ring, with intestinal ischemia and reddened to dark-red serosa. Predisposing factors included previous surgeries (2/6) and patent inguinal ring (1/6). Intussusception involved the small intestine (3/4) and ileocecum (1/4). Foals with lack of colostrum intake and concomitant pneumonia was a characteristic presentation (3/4). Grossly, the intussusceptum slipped into intussuscipiens, with diffuse deep black-red discoloration. Other causes included large colon displacement (2/5), extrinsic and intrinsic obstruction of the small intestine (2/5), and an intestinal adenocarcinoma. Noninfectious gastrointestinal diseases are major causes of death in horses. Epidemiological and gross features of the conditions should be accounted to obtain a final diagnosis of the cause of the colic.(AU)

Foi conduzido um estudo retrospectivo em busca de casos dessas doenças envolvendo cavalos de 2005 a 2017. Durante esse período, 114 equinos morreram devido a doenças não infecciosas do trato gastrointestinal, e as principais causas foram: dilatação gástrica (27/114), vólvulos (27/114), enterolitíase (20/114), ruptura retal (colônica) (15/114), compactação gástrica ou cecocolônica (10/114), encarceramentos (6/114), intussuscepções (4/114), e outros (5/114). Animais sem raça definida (56/114) e machos (69/114) foram mais afetados. Os equinos apresentavam uma média e mediana de idade de 10 e 10,9 anos, respectivamente. A dilatação gástrica primária era caracterizada por distensão do estômago por moderada a grande quantidade de conteúdo, que em 21 casos provocava ruptura da parede gástrica na curvatura maior (peritonite), e o principal fator predisponente foi sobrecarga alimentar (17/27). Vólvulo intestinal ocorreu no intestino delgado e no intestino grosso (14 e 13 casos, respectivamente). Macroscopicamente, havia isquemia intestinal com serosa avermelhada a enegrecida e mucosa difusamente avermelhada. A enterolitíase causou obstrução parcial ou completa do cólon dorsal direito (9/20), cólon transverso (4/20), cólon menor e cólon dorsal direito (3/20), cólon menor (2/20), e reto e cólon maior direito (2/20). Perfuração de vísceras e peritonite foram observadas em 11 casos. A ruptura retal (colônica) envolveu o reto (10/15), reto/cólon menor (4/15) e cólon menor (1/15). Essa era caracterizada por ruptura transmural focalmente extensa, com bordos avermelhados e peritonite retroperitoneal a difusa. Traumas relacionados à palpação (11/15) foram a principal causa. Compactações afetaram o cólon maior (7/10), ceco (2/10) e estômago (1/10). Encarceramentos consistiram em hérnias inguinoescrotais (2/6), encarceramento de alças intestinais por falha no mesentério (2/6), hérnia diafragmática e eventração umbilical. Macroscopicamente, os órgãos estavam constritos por um anel hernial, com isquemia intestinal e serosa avermelhada a vermelho-escura. Fatores predisponentes incluíram cirurgias prévias (2/6) e anel inguinal patente (1/6). Intussuscepções envolveram o intestino delgado (3/4) e íleoceco (1/4). A apresentação característica foi em potros com falta de colostro e concomitante pneumonia. Macroscopicamente, o intussuscepto deslizava em direção ao intussuscepiente, exibindo coloração vermelho-enegrecida difusa. Outras causas incluíram deslocamento de cólon maior (2/5), obstrução extrínseca e intrínseca do intestino delgado (2/5), e um caso de adenocarcinoma intestinal. Doenças não infecciosas são importantes causas de morte em equinos. Os aspectos epidemiológicos e macroscópicos das condições devem ser considerados para o que o diagnóstico final da causa da cólica seja obtido.(AU)

Mechanical properties of bean grains (BRSMG Majestic) coated with carnauba wax / Propriedades mecânicas de grãos de feijão cultivar BRSMG Majestoso revestidos com cera de carnaúba

The objective of this research was to determine the mechanical properties of beans (BRSMG Majestuoso) coated with carnauba wax solution. Grains with 0.1481 (d.b.) moisture content was used. Treatments 0, 1 and 2 were respectively defined as the control sample, application of the wax diluted 1/1 (carnauba wax solution/water) and application of carnauba wax without dilution. Uniaxial compression tests were performed in the universal test apparatus, TA HD Texture Analyzer with 500 N load cell. Compression tests were carried out during the storage period of in-nature grains, in those that underwent the hydration process at 40 and 50°C of temperature and in grains during the cooking process. Only the storage time had a significant effect (P<0.05) on the rupture force and the proportional deformity module. Hydration and cooking of the grains provided a reduction in the values of the studied variables.(AU)

Objetivou-se com este trabalho determinar as propriedades mecânicas de grãos de feijão cultivar BRSMG Majestoso revestidos com cera de carnaúba. Foram utilizados grãos com teor de água de aproximadamente 0,1481 decimal b.s. (base seca), tratados com solução de cera de carnaúba. Parte destes destinou-se à amostra testemunha, uma a aplicação de cera diluída na proporção de 1/1 (solução de cera de carnaúba/água) e outra a aplicação apenas de solução de cera de carnaúba, tratamentos 0, 1 e 2, respectivamente. Foram realizados ensaios de compressão uniaxiais no aparelho universal de testes, TA. HD Texture Analyser, com célula de carga de 500 N. Os testes de compressão foram realizados ao longo do período de armazenamento nos grãos in natura, naqueles que passaram pelo processo de hidratação nas temperaturas de 40 e 50°C e em grãos ao longo do processo de cocção. Apenas o tempo de armazenamento teve um efeito significativo (P<0,05) sobre a força de ruptura e o módulo proporcional de deformidade. A hidratação e a cocção dos grãos proporcionaram redução nos valores das variáveis estudadas.(AU)

Idiopathic urinary bladder rupture in two mares / Ruptura idiopática de bexiga urinária em duas éguas

Urinary bladder rupture is rarely reported in adult horses and is usually associated with parturition, history of traumaor urethral obstruction. This paper reports two cases in mares free of these predisposing factors, diagnosed throughclinical manifestations, abdominal ultrasound and abdominocentesis, corrected by cystorrhaphy through laparotomy.While recovery was satisfactory in one case, the other case had complications in celiorraphy such as development ofincisional hernia, small colon eventration and intestinal adherences, opting by the euthanasia of the animal. These reportsare important because of the rarity with which they occur in adult mares. The different prognoses may be related to theseverity of each case, according to the location and extension of the wound, which directly or indirectly influence thetechnique and recovery of the animals.

A ruptura de bexiga urinária é raramente relatada em equinos adultos, sendo normalmente associada ao parto, antecedentesde trauma ou obstrução de uretra. Este trabalho relata dois casos em éguas livres destes fatores predisponentes,diagnosticados através de manifestações clínicas, ultrassonografia abdominal e abdominocentese, corrigidos por cistorrafiaatravés de laparotomia. Em um dos casos a recuperação ocorreu satisfatoriamente, porém no outro houve complicaçõesna celiorrafia como desenvolvimento de hérnia incisional, eventração de cólon menor e posterior desenvolvimento deaderências intestinais, optando-se pela eutanásia do animal. Estes relatos são importantes pela raridade com que ocorremem éguas adultas. Os diferentes prognósticos podem estar relacionados à gravidade de cada caso, de acordo com o locale extensão da ferida, que direta ou indiretamente influenciam na técnica empregada e recuperação dos animais.

Estudo comparativo entre métodos manual e digital no cálculo do ângulo do platô tibial em cães / Comparative study of manual and digital method in the calculation of the tibial plateau angle in dogs

São poucos os dados publicados sobre a aplicabilidade ou a confiabilidade dos métodos digitais para mensuração do ângulo do platô tibial (APT) em comparação à mensuração manual. O objetivo deste estudo foi comparar o APT obtido pelo cálculo manual padrão, em filmes radiográficos, com os valores obtidos por cálculos em imagens digitais, por meio do software do computador. Foram analisadas radiografias digitais do membro pélvico, direito e esquerdo, em perfil verdadeiro, de 20 cães saudáveis, com idade superior a um ano. Três observadores com graus de experiência semelhantes em cálculo do APT realizaram as mensurações em cada radiografia. Primeiramente, foram calculados os ângulos dos platôs tibiais manualmente nas películas radiográficas e, posteriormente, os cálculos foram realizados na imagem digital, por meio do software para medicina veterinária do sistema de raios X digital. Os resultados do presente estudo demonstraram diferenças significativas entre os métodos, com valor das médias do cálculo digital 20,48±3.71 e do cálculo manual 23.90±4.02. Valor de P foi < 0,01 na comparação entre médias dos dois grupos. Na avaliação interobservadores, houve diferença significativa no cálculo manual no perfil direito, o que sugere maior variação no cálculo manual quando comparado ao digital. O cálculo realizado pelo software apresentou menor variação nos valores interobservadores. Acredita-se que a menor variação obtida nos resultados aqui apresentados se dê em razão das facilidades proporcionadas pelo software. Conclui-se que houve diferença entre os valores obtidos por meio dos métodos convencional e digital no cálculo do ângulo do platô tibial, sendo os valores digitais menores entre os observadores, e que o método digital no cálculo do ângulo do platô tibial levou à menor variação quando comparado ao método manual.(AU)

There are few published data on the applicability and reliability of digital methods for measuring the TPA compared with manual measurement. The objective of this study was to compare the TPA obtained by calculating standard manual on conventional radiographs, with the values obtained by calculations in digital images through a computer program. Bilateral digital radiographs of hind limb were analyzed in true profile for 20 healthy dogs older than two years. Three observers with similar levels of experience in calculating the TPA conducted measurements on each radiograph. First we calculated the angle of the tibial plateaus manually in x-ray film and then the calculations were made through the program offered by the computer program in the digital image. The results of this study showed significant differences between the methods, with average value of 20.48±3.71 digital calculating average and 23.90±2.4 in the manual calculation. P value was < 0.01 when comparing averages. No significant difference in manual calculation in right profile were found between interobserver assessments, suggesting greater variation in manual calculation compared to digital. The calculation performed by the software showed less variation in values. The slight variation obtained in our results is believed to be due to the facilities provided by the software. There was a difference between the values obtained by means of conventional and digital methods for calculating the angle of the tibial plateau, and the smaller digital values between the observers and the digital method in the calculation of the tibial plateau angle led to less variation when compared to the manual method.(AU)

Torção testicular em saco escrotal de canino jovem / Testicular torsion in the scrotum of a young canine

Background: Testicular torsion is a rare condition in canines, affecting any animal, regardless of age and racial predisposition. The possible cause, when talking about young dogs, is often unreliable, and can be associated with traumatic processes or excessive physical activity. Dogs with spermatic cord twist usually show signs of acute and sudden pain in one of the testicles that can be propagated to the abdomen; besides edema, heat and scrotal flush. The absence of blood flow toward the affected testicle can be observed, however, the definitive diagnosis can only be confirmed through a surgical procedure or necropsy. This situation is considered a medical emergency that requires surgical intervention for resolution and has treatment of choice bilateral orchiectomy. The objective of this study was to report the case of a testicular torsion inside the scrotal pouch of a young dog.Case: A 6-month-old male Poodle dog, weighing 6.40 kg, was attended at the Metropolitan Veterinary Polyclinic, located in the municipality of Caucaia, Ceará, Brazil. During anamnesis it was reported by the owner of the animal an suddenly increase in volume of the scrotal pouch and right testicle. The physical examination observed normal mucous membranes, lymphadenopathy, capillary refill time of 2 s, temperature of 39.2°C, heart rate of 72 beats per minute and 68 breaths per minute. Hematologic test was requested, creatinine, dosage of ALT and ultrasound as complementary exams. The result of hemogram presented thrombocytopenia (150,000/mm3 ) and the presence of giant platelets. Besides, a biochemical series presented no alterations. On the Doppler ultrasound, the right testicle proved to show loss of normal structure, enlarged scrotum, hyperechoic epididymal region with adjacent liquid and absence of local vascularization.[...]

Técnica de TightRope modificada no tratamento da doença do ligamento cruzado cranial em cães: resultados a longo prazo / Modified TightRope technique for treatment of the cranial cruciate ligament disease in dogs: long term outcomes

O objetivo deste estudo foi descrever os resultados a longo prazo do uso da técnica extracapsular TightRope (TR) modificada no tratamento da doença do ligamento cruzado cranial (LCCr) em oito cães (10 articulações) com peso corporal variando entre 4kg e 28kg. Todos os animais selecionados foram submetidos aos exames ortopédicos específicos, sendo diagnosticada ruptura completa do LCCr pelos testes de gaveta e de compressão tibial. Realizaram-se exames radiográficos convencionais e em posição de estresse das articulações. A técnica TR foi modificada utilizando-se o fio de náilon substituindo o fio de fibra empregado na técnica original, facilitando a disponibilidade de obtenção do material. Houve também modificação na origem da perfuração do túnel tibial, sendo realizada imediatamente cranial ao sulco do tendão extensor digital longo. Todos os cães foram submetidos ao exame radiográfico tanto no pós-operatório imediato como no tardio. Aos 30 dias após a intervenção cirúrgica, os pacientes apresentavam claudicação nos membros pélvicos operados de grau discreto a moderado. Foi observado discreto movimento de gaveta cranial em 60% das articulações acometidas. Aos três meses após o procedimento cirúrgico, os animais apresentaram ausência de dor e discreta redução na amplitude dos movimentos articulares. Em duas articulações (20%) observou-se discreto deslocamento cranial da tíbia no teste de gaveta. Nesta fase, 80% dos membros avaliados apresentavam apoio normal. Um ano após a intervenção cirúrgica, observou-se ao exame radiográfico discreta progressão da doença articular degenerativa em 50% das articulações operadas. Das oito articulações avaliadas a longo prazo, em apenas um membro operado observou-se discreta claudicação com reduzida transferência de peso para o membro contralateral. Os demais membros pélvicos avaliados (87,5%) demonstraram ausência de claudicação e adequada recuperação da função articular. Concluiu-se que a técnica cirúrgica extracapsular TR modificada mostrou-se efetiva como opção de tratamento para doença do LCCr em cães de porte pequeno e médio, não apresentando complicações. As modificações do fio cirúrgico e da perfuração da tíbia na técnica TR parecem ter efeitos positivos na estabilização da articulação do joelho.(AU)

The aim of the study was to describe the long term outcomes of the modified extracapsular TightRope (TR) technique in the treatment of the cranial cruciate ligament (CCL) disease in eight dogs (10 joints) with a body weight ranging from 4kg to 28kg. The animals were submitted to specific orthopedic examinations and were diagnosed with total CCL rupture by drawer and tibial compression tests. Conventional and stress positional radiographic examinations of the affected joints were performed. The TR technique was modified using the nylon suture thread replacing the fiber suture used in the original technique, which facilitated the availability of obtaining the material. There was also modification in the origin of the tibial tunnel perforation that was performed immediately cranial to the groove of the long digital extensor tendon. The dogs underwent radiographic examination in the immediate postoperative and in later periods. At one month after surgical procedure, the animals showed mild or moderate lameness in the affected pelvic limbs. Mild cranial tibial drawer was observed in 60% of the operated joints. At three months after the procedure, the animals have mild decrease in the range of joint motion, but without signs of pain. Two stifle joints (20%) showed a slight cranial displacement of the tibia in the drawer test. In this period, 80% of the affected joints showed normal limb support. At one year after the procedure, radiographic examination showed a discrete progression of the degenerative joint disease in 50% of the operated joints. The long term outcomes were obtained from eight joints and in only one pelvic limb was observed mild lameness with slight weight transfer to the normal contralateral limb. All other evaluated pelvic limbs (87.5%) showed no lameness and proper recovery of joint function. In conclusion, the modified TR extracapsular surgical technique proved to be effective as a treatment option for CCL disease in small and medium dogs, with no complications. Modifications of the surgical suture thread and the tibial site perforation of the TR technique seem to have positive effects on stabilization of the stifle joint.(AU)
