Lesão na região metacarpiana do membro torácico esquerdo de bezerra Gir decorrente de contenção para pesagem / Injury in the metacarpinal region of the left thoracic limbs resulting from retention for weighing in a Gir calf

Fraturas ósseas e luxações são mais comuns em animais jovens e, na maioria das vezes, essas fraturas ocorrem devido ao manejo incorreto desses animais, podendo levar a uma queda de produção a curto ou longo prazo, gerando perdas econômicas e produtivas de animais de alto padrão genético. Nesse contexto, o objetivo deste trabalho foi relatar a ocorrência de uma fratura na região metacarpiana do membro torácico esquerdo de uma bezerra Gir de 12 dias de idade, causada por uma contenção ineficaz durante a pesagem. O animal proveniente de uma fazenda em Umirim/CE foi encaminhado ao Hospital Veterinário de Grandes Animais do Centro Universitário INTA em Sobral/CE. Ao passar pelo exame radiográfico, foi constatada a fratura na região metacarpiana do membro torácico esquerdo. O animal foi imobilizado de forma manual, seguindo-se métodos semiológicos para minimizar o estresse. Para a imobilização do membro, foi utilizada a muleta de Thomas modificada e bandagens, associadas ao controle da dor com as drogas Flunixin meglumine (1,1mg/kg) e Fenilbutazona (4,4mg/kg). Depois da imobilização, o animal seguiu internado no HOVET-GA e, após 18 dias, foi realizada uma nova radiografia para ver o progresso a partir do tratamento adotado. Constatou-se a formação de um calo ósseo, com a ossificação da fratura, não sendo necessário o encaminhamento cirúrgico do animal. Assim, o tratamento com muleta de Thomas modificada foi efetivo para a recuperação do membro fraturado, além de ser um tratamento de baixo custo e fácil aplicação, tendo o animal apresentado uma boa resposta ao tratamento terapêutico para controle da dor.

Bone fractures and dislocations are more common in young animals and mostly occur due to incorrect handling of these animals, which can lead to a short or long-term drop in production, generating economic and productive losses of animals of high genetic standard. This study aimed to report the occurrence of a fracture in the metacarpal region of the left thoracic limb of a 12-day-old Gir heifer, caused by an ineffective restraint during weighing. The animal from a farm in Umirim/CE was sent to the Veterinary Hospital of Large Animals of the University Center INTA in Sobral/CE. The radiographic examination found a fracture in the metacarpal region of the left thoracic limb. The animal was manually immobilized following semiological methods to minimize stress. For the limb immobilization, a modified Thomas crutch and bandages associated with pain control with the drugs Flunixin meglumine (1.1mg/kg) and Phenylbutazone (4.4mg/kg) were used. After immobilization, the animal remained hospitalized at HOVET-GA and after 18 days a new radiograph was performed to evaluate the progress achieved with the treatment adopted. It was found the formation of a bone callus with the ossification of the fracture, not requiring the surgical referral of the animal. Thus, the treatment with the modified Thomas crutch was effective for the recovery of the fractured limb, in addition to being a low-cost and easy-to-apply treatment. The animal showed a good response to the therapeutic treatment for pain control.

Fraturas apendiculares em cães e gatos: métodos de tratamento e desfechos / Appendicular fractures in dogs and cats: treatment methods and outcome

O objetivo deste estudo retrospectivo foi identificar a ocorrência de fraturas apendiculares em cães e gatos, os métodos de tratamento e os resultados obtidos com os mesmos, no Hospital Veterinário (HV) da Universidade Regional do Noroeste do Estado do Rio Grande do Sul (Unijuí), no município de Ijuí - RS, no período de abril de 2013 a abril de 2022. De um total de 370 procedimentos cirúrgicos para tratamento de fraturas do esqueleto apendicular, 117 foram em fêmur (31,6%), 77 em tíbia e fíbula (20,8%), 62 em rádio e ulna (16,8%), 49 em úmero (13,2%), 45 em pelve (12,2%), 7 em metatarso e metacarpo (1,9%), 7 em tarso e carpo (1,9%), 4 em escápula (1,1%) e 2 em falanges (0,5%). O número de procedimentos foi superior ao número de animais, pois alguns apresentavam mais de uma fratura em diferentes ossos. Entre os 329 animais reportados neste estudo, concluiu-se que a principal causa de fraturas em cães e gatos foi atropelamento, sendo os filhotes os mais acometidos e as fraturas femorais as mais frequentes. Os fixadores esqueléticos externos destacaram-se como o método mais utilizado e o desfecho das osteossínteses foi satisfatório, sendo que a maior casuística correspondeu a fraturas cicatrizadas.

This retrospective study aimed to identify the occurrence of appendicular fractures in dogs and cats, treatment methods, and results obtained with them, at the Veterinary Hospital (VH) of the Regional University of the Northwest of the State of Rio Grande do Sul (Unijuí), in the city of Ijuí/RS, from April 2013 to April 2022. A total of 370 surgical procedures for the treatment of fractures of the appendicular skeleton was performed: 117 were in the fêmur (31,6%), 77 in the tíbia and fíbula (20,8%), 62 in the radius and ulna (16,8%), 49 in the humerus (13,2%), 45 in pélvis (12,2%), 7 in metatarsus and metacarpus (1,9%), 7 in tarsus and carpus (1,9%), 4 in the scapula (1,1%), and 2 in phalanges (0,5%). The number of procedures was higher than the number of animals, as some had more than one fracture in different bones. Among the 329 animals reported in this study, it was concluded that the main cause of fractures in dogs and cats was being run over, puppies were the most affected, and femoral fractures were the most frequent. External skeletal fixators stood out as the most used method and the outcome of osteosynthesis was satisfactory, with the largest number of cases corresponding to healed fractures.

Correção de deformidade flexural da articulação metacarpofalangeana em uma bezerra / Correction of flexural deformity of the metacarpophalangeal joint in a calf

Background: The congenital flexural deformity is common in cattle, often affecting the metacarpophalangeal joint of thethoracic limbs. The deformity may be mild, moderate, or severe, and the therapy depends on the limb’s degree of flexionand the affected joint. In severe deformities, tenotomy of the flexor tendons and desmotomy of the suspensor ligament isrecommended. However, this surgical technique may not be sufficient to promote limb extension, and other interventionsmay be necessary. Thus, the purpose of this report is to describe a technique to correct severe flexural deformities of themetacarpophalangeal joint in calves.Case: A 3-month-old, female, Dutch-bred calf weighing 46 kg was referred for treatment of congenital flexural deformity.On attendance, the patient presented severe deformity in the right thoracic limb and mild in the left thoracic limb both at theheight of the metacarpophalangeal joints. During palpation it was possible to notice that the flexor tendons were contractedin both limbs. Radiographic exams were performed to rule out the presence of other diseases, confirming the diagnosis offlexural deformity. The patient was referred to surgery to correct the anatomical anomaly. The animal was submitted to general anesthesia and placed in right lateral decubitus. In the left thoracic limb, an incision was made in the medial region ofthe metacarpal bone, the tissues were divulsioned until the superficial digital and deep digital flexor tendons were exposed;these structures were sectioned with a scalpel, and the limb was extended, returning to the standard anatomical position. Inthe right thoracic limb, the same procedure was performed, but during the limb extension test, we observed that the limbremained flexed, we then followed with a second incision and section of the deep...

Clinical and arthroscopic presentation of horses with osteochondral fragmentation at metacarpophalangeal and metatarsophalangeal joints: a 10-year study (2010-2019) / Caracterização clínica e artroscópica de equinos com fragmentação osteocondral em articulações metacarpofalangeana e metatarsofalangeana: estudo de 10 anos (2010-2019)

This study aimed to characterize the clinical and arthroscopic presentations of horses with osteochondral fragmentation at the metacarpophalangeal and metatarsophalangeal joints at the Veterinary Hospital of the University of São Paulo in a 10-year period (2010-2019). The hind limbs were affected similarly to the plantar and dorsal fragments from the first phalanx, while the thoracic limbs had a more frequent occurrence on the dorsal aspect of the joint. The Brazilian Sport Horses were the most frequently observed breed. The degree of lameness was variable and might be related to fragment localization, animal age, and physical activity. There was a significant statistical difference between the joint effusion and degree of lameness; therefore, it can be considered that the joint effusion is related to degenerative joint processes and might be triggered by the presence of the osteochondral fragment. Surgical correction, especially when performed in young animals using an arthroscopic procedure is probably the best treatment option for most cases, possibly acting as a minimizer of the occurrence of secondary joint degeneration. Prospective studies of specific breeds with a larger number of animals can expand this clinical characterization and enable a better understanding of the animal's recovery after surgical or conservative management.

O objetivo deste estudo foi caracterizar a apresentação clínica e artroscópica de equinos com fragmentação osteocondral em articulação metacarpo/metatarsofalangeana atendidos no Hospital Veterinário da Universidade de São Paulo, no período de 10 anos (2010-2019). Os membros pélvicos são mais acometidos com fragmentos plantaromediais da primeira falange, enquanto os membros torácicos apresentam uma caracterização de ocorrência de fragmentação dorsal da primeira falange, sendo o Brasileiro de Hipismo a raça de maior ocorrência nesta casuística. O grau de claudicação foi variável e pode relacionar-se com a localização do fragmento, a idade e o nível de atividade atlética desenvolvida. Houve relação estatística significativa entre a presença de efusão articular e o grau de claudicação, por isso suscita-se sobre a efusão relacionar-se com processos degenerativos articulares que podem ser desencadeados pela presença do fragmento osteocondral. A correção cirúrgica por meio de procedimento artroscópico provavelmente consiste na melhor opção de tratamento para a maioria dos casos, principalmente quando realizada em animais jovens, possivelmente atuando como minimizador da ocorrência de degeneração articular secundária. Estudos prospectivos de raças específicas e com um número maior de animais podem ampliar essa caracterização clínica e possibilitar um entendimento sobre a evolução após a opção ou não pelo tratamento cirúrgico.

A ocorrência de fraturas é comum em cães e gatos, principalmente as ocasionadas por atropelamento. Diante disso, um estudo retrospectivo de cães e gatos atendidos entre abril de 2013 e abril de 2020 no Hospital Veterinário da Universidade Regional do Noroeste do Estado do Rio Grande do Sul foi realizado. O estudo teve como objetivo identificar a prevalência das fraturas apendiculares, a etiologia e o tratamento. De um total de 222 animais, 197 (88,7%) eram cães e 25 (11,3%) eram gatos, os quais apresentaram 254 fraturas apendiculares. Quanto às fraturas, os seguintes resultados foram observados: 86 fraturas de fêmur (33,9%), 58 fraturas de tíbia e fíbula (22,8%), 24 fraturas da pelve (9,4%), 39 fraturas do rádio e da ulna (15,4%), 40 fraturas do úmero (15,7%), 3 fraturas de escápula (1,2%), 3 fraturas de metatarso (1,2%) e 1 fratura de metacarpo (0,4%). Os animais mais afetados foram os cães: machos (n=100; 57,8%), com idade de até três anos (n=123; 62,4%), sem raça definida (n=95; 45%), de porte pequeno (n=123; 62,4%). Desta forma, conclui-se que o perfil de animais com fraturas apendiculares da Região Noroeste do Rio Grande do Sul é: cães machos, sem raça definida, jovens, de pequeno porte, sendo que o fêmur foi o osso mais acometido devido a acidentes automobilísticos.

The occurrence of fractures is common in dogs and cats, especially those caused by being run over. Therefore, a retrospective study of dogs and cats attended between April 2013 and April 2020 at the Veterinary Hospital of the Regional University of the Northwest of the State of Rio Grande do Sul was carried out. The study aimed to identify the prevalence of appendicular fractures, the etiology, and the treatment. Among 222 animals, 197 (88.7%) were dogs and 25 (11.3%) were cats, which presented 254 appendicular fractures.

Clinical and radiographic aspects of metacarpal remodeling secondary to a rubber band (latex) compression in a dog

Background: Musculoskeletal disorders are a common complaint in veterinary small animal casuistic. Along with fractures, degenerative and of carcinogenic etiology are the most frequent and radiographic lesion pattern at these diseases isrelative well defined. However, traumatic lesions, considering its innumerous possibilities, may cause unusual clinical andradiographic signs which will delay diagnosis and consequently, adequate treatment. A case of bone osteolysis caused bya compressive trauma by a rubber band is described with its clinical, laboratorial and radiographic aspects.Case: A 2-year-old female dog was attended at the Veterinary Hospital of the Dom Bosco Catholic University (UCDB),with main complaint being an unresponsive to treatment lesion at the left thoracic limb. At physical examination it wasobserved lameness of the left thoracic limb with an ulcerative lesion at the palmar surface. At the center of the ulcer a 0.3cm line shaped yellow object was identified, similar to a rubber band. Traction was made and the object distended 5 cmwithout breaking nor leaving the injury. Showing signs of discomfort, the patient was then sedated for further manipulation. A blood sample for complete blood count and serum biochemistry was collected and radiographic image of the leftcarpometacarpal-phalangeal region was acquired. Blood analysis revealed moderate thrombocytopenia with an unremarkable serum biochemistry profile (alanine aminotransferase, alkaline phosphatase, creatinine and urea). It was observedmetacarpals with increased radiopacity in bone tissue in the mid-diaphysis topography of the II, III, IV and V metacarpalbones, presence of bone remodeling with radiolucent area and slight bone loss (osteolysis) in the mid-diaphysis associatedwith discrete sclerosis of the medullary cavity of the II, III and V metacarpals.

Manejo da deformidade flexural congênita em bezerro - aspectos cirúrgicos e patológicos / Management of a congenital flexural deformity in a calf - surgical and pathological aspects

Background: Flexural deformities are anatomical deviations, in varying degrees, of one or more joints, and may have a congenital or acquired origin. Congenital contracture of the deep digital flexor tendon (DDFT) affects newborn calves and results in hyperflexion of the metacarpal-phalangeal joint, which in severe cases means that the animal must support its own weight on its fetlock joints. The aim of this study is to report the rapid and successful result of applying bilateral total tenotomy technique on a newborn bovine that had been diagnosed with severe bilateral DDFT contracture in the thoracic limbs. Case: A 3-week-old male bovine with a history of difficulty in maintaining a quadrupedal position was attended at the Veterinary Hospital of the Federal University of Tocantins. The animal had severe bilateral locomotor alterations in the thoracic members to the point that he walked on his fetlock joints. The physical examination revealed clinical parameters within the normal range. However, the locomotor system examination showed severe flexor deformity in the bilateral metacarpal-phalangeal joints, and the limbs were being supported on the dorsal face of the fetlock joints, which presented ulcerations, and was suggestive of a shortening of the DDFT. Based on the patient’s history and clinical examination, as well as the severity of the tendon contractures, surgical treatment using the DDFT bilateral total tenotomy technique was decided upon. Postoperative treatment consisted of 2.5 mg/kg of enrofloxacin intramuscularly (IM), SID, for 5 days and 0.5 mg/kg meloxicam via IM, SID, for 3 days; as well as a dressing (cotton, medical bandage and a PVC mold) on the thoracic limbs to provide support and allow the animal to..

Intra-articular concentration of gentamicin administered by intravenous regional limb perfusion in healthy horses / Concentração intra-articular de gentamicina administrada por perfusão regional intravenosa em membros de equinos sadios

Intravenous regional limb perfusion (IRLP) is an efficient method to treat horses with synovial infections. However, information on the dose, volume, and intervals of administration is lacking. The aim of this study was to evaluate the intra-articular concentration of gentamicin administered by IRLP in horses over 24 h post-administration and evaluate the influence of the total perfused volume. Twenty horses were assigned to two treatment groups. Gentamicin 60 group (G60, n=10) and Gentamicin 250 group (G250, n=10) received IRLP of 6.6 mg/kg of gentamicin diluted in Ringers lactate for a total volume of 60 ml (G60) and 250 ml (G250), respectively. Synovial fluid harvests were performed in the metacarpophalangeal joint before (0) and 4, 8, 12, 16, 20, and 24 hours after IRLP. Agar diffusion was the assay for measuring gentamicin concentrations. Four hours after IRLP, the intra-articular concentration of gentamicin was 47.58±49.21 g/ml in G60 and 10.92±6.11 g/ml in G250. During the 24 h of harvest, the intra-articular concentration of gentamicin remained above the minimum inhibitory concentration for horses (MIC; 2 g/ml) in both experimental groups. In G60, the concentration of gentamicin in synovial fluid reached the maximal concentration and remained 8 to 10-fold higher than the MIC (Cmax: 16 to 20 g/ml) during 12 h after IRLP. These findings support that IRLP with 6.6 mg/kg of gentamicin diluted to a volume of 60 ml promotes intra-articular concentrations higher than 250 ml, remaining above the MIC for 24 h and at the maximum concentration for 12 h.(AU)

A perfusão regional intravenosa (PRI) em membros de equinos é um método comprovadamente eficiente para o tratamento de infecções sinoviais, porém ainda existem lacunas quanto à dose, volume e intervalos de administração a serem utilizados. Neste estudo, objetivou-se avaliar a concentração intra-articular da gentamicina administrada por PRI em equinos, ao longo de 24 horas pós-administração, bem como avaliar a influência do volume total perfundido. Vinte equinos foram distribuídos em dois grupos experimentais, Grupo Gentamicina 60 (G60) e Grupo Gentamicina 250 (G250), representados por 10 equinos em cada grupo que receberam, por PRI, 6,6 mg/kg de gentamicina diluída em Ringer lactato para um total de 60 ml (G60) ou 250 ml (G250). As colheitas de líquido sinovial foram realizadas, na articulação metacarpo-falangeana, antes do início do experimento e após 4, 8, 12, 16, 20, e 24 horas. Difusão em ágar foi o método para doseamento das concentrações de gentamicina. Quatro horas após a PRI, a concentração intra-articular da gentamicina era de 47,58±49,21 µg/ml no G60 e 10,92±6,11 µg/ml no G250. Durante as 24 horas de colheita, a concentração intra-articular de gentamicina permaneceu acima da concentração inibitória mínima (CIM) (2 g/ml) em ambos os grupos experimentais. No G60, as concentrações de gentamicina no líquido sinovial atingiram a concentração máxima e mantiveram-se 8 a 10 vezes mais elevadas que a CIM (Cmáx: 16 a 20 g/ml) durante 12 horas após a PRI. Conclui-se que a PRI em membros, com 6,6 mg/kg de gentamicina diluída para o volume de 60 ml, promove concentrações intra-articulares mais elevadas que o volume de 250 ml, permanecendo acima da CIM durante 24 horas e em concentração máxima durante 12 horas.(AU)

Pulmonary carcinoma metastasis in a feline digit

Background: Primary pulmonary neoplasia is rare in domestic cats, with fewer than 1% of all tumors diagnosed in thisspecies. Primary lung tumors have a high percentage of metastases, observed in up to 75% of cases in cats. The lung-digitsyndrome is characterized by primary pulmonary neoplasms with metastases to the extremities of the limbs, mainly distalphalanges, possibly involving several digits and more than one limb. This report describes a case of pulmonary carcinomametastasis in a cat digit.Case: A 16-year-old neutered female cat was showing increased volume of the fourth digit was examined at the Universityof Caxias do Sul veterinary clinic. The animal also showed signs of progressive weight loss, apathy and limping on theright thoracic limb. After clinical evaluation, the animal was sent for radiographic examination of the right metacarpal/phalangeal region and the thorax. A radiopaque structure was observed with discreet central regions of radiolucency,measuring approximately 3 cm in height, 3.4 cm in length and 2.4 cm in depth in the left caudal lung, suggesting neoplasiaor pulmonary abscess. Digit image revealed osteolysis of the right and middle distal phalanx measuring 2 cm in height, 3cm in breadth and 1 cm in length. In view of these radiographic changes, we performed fine needle aspiration cytology ofthe digit and a nodule in the region of the skeletal musculature of the right thoracic limb. Cytological evaluation revealedcells had cilia on their surface (compatible with respiratory epithelium). The cytologic findings of the fine-needle biopsywere suggestive of carcinoma. After stabilization, the digit was amputated. The material was sent to the laboratory of theFederal University of Pelotas for histopathological examination...

Sites of anesthetic block of the lateral and medial palmar metacarpal nerves in equines of indeterminate breed

Background: Local anesthesia blockage at equines claudication diagnosis besides favoring the beginning of the therapyand relieving patients pain, it allows the identification of the specific affected region and its origin, however, if it isdone incorrectly (by improper volume of anesthetics application and/or mistakenly nerve identification due to the lack ofanatomic referential) it may cause inflammation, infection or even tissue necrosis. The aim was describing anatomicallylateral and medial palmar metacarpal nerves in equines to improve diagnostic anesthetic block techniques on four metacarpophalangeal articulation joints of the specie.Materials, Methods & Results: A number of 20 thoracic limbs from 10 equines of indeterminate breed were used to befixated in 10% phormaldehyde and with a marked arterial system by water solution of red dyed latex. The structures wereidentified by dissection, and their denomination bases on Nomina Anatomica Veterinaria (N.A.V.) by the InternationalCommittee on Veterinary Gross Anatomical Nomenclature. The study had been approved by the Board of Ethics in AnimalUse of the University Center of Patos de Minas (UNIPAM), protocol n° 18/17. The lateral and medial palmar metacarpalnerves have been observed in all of the specimens originated from the deep branch of lateral palmar nerve, immediatelydistal to the intercarpal articulation. After its origin, the first nerve stretched ipsilaterally from the common trunk, whilstthe second nerve positioned counter-lateral manner after superficially crossing the interosseus muscle. Both penetrated atthe level of the mid third of the referred muscle and the metacarpal bone III and, assumed respectively a parallel medialposition to the metacarpal bone IV and lateral to the metacarpal II, being intimately associated to the palmar face of themetacarpal bone III.

Background: Local anesthesia blockage at equines claudication diagnosis besides favoring the beginning of the therapyand relieving patient’s pain, it allows the identification of the specific affected region and its origin, however, if it isdone incorrectly (by improper volume of anesthetics application and/or mistakenly nerve identification due to the lack ofanatomic referential) it may cause inflammation, infection or even tissue necrosis. The aim was describing anatomicallylateral and medial palmar metacarpal nerves in equines to improve diagnostic anesthetic block techniques on four metacarpophalangeal articulation joints of the specie.Materials, Methods & Results: A number of 20 thoracic limbs from 10 equines of indeterminate breed were used to befixated in 10% phormaldehyde and with a marked arterial system by water solution of red dyed latex. The structures wereidentified by dissection, and their denomination bases on Nomina Anatomica Veterinaria (N.A.V.) by the InternationalCommittee on Veterinary Gross Anatomical Nomenclature. The study had been approved by the Board of Ethics in AnimalUse of the University Center of Patos de Minas (UNIPAM), protocol n° 18/17. The lateral and medial palmar metacarpalnerves have been observed in all of the specimens originated from the deep branch of lateral palmar nerve, immediatelydistal to the intercarpal articulation. After its origin, the first nerve stretched ipsilaterally from the common trunk, whilstthe second nerve positioned counter-lateral manner after superficially crossing the interosseus muscle. Both penetrated atthe level of the mid third of the referred muscle and the metacarpal bone III and, assumed respectively a parallel medialposition to the metacarpal bone IV and lateral to the metacarpal II, being intimately associated to the palmar face of themetacarpal bone III. Distally, those nerves emerged from a palmar position to a lateral and medial to...

DIGITAL CONTRAST VENOGRAPHY IN VIVO OF THE FORELIMB AND HINDLIMB IN HEALTHY SHEEP AND GOAT

Abstract The venographic examination allows diagnosing and treating foot diseases. It can be the basis of studies about the administration of medication in the hoof region. The aim of the study was to describe the venographic pattern in the distal region of the forelimb and hindlimbs of healthy sheep and goats, as well as to compare vascularization between them. Ten clinically healthy sheep and goats, five male and five female of different breeds, aged 2 to 4 years and weighing 45 to 63 kg were used. The forelimbs and hindlimbs were subjected to contrast venography of the distal region. The venograms were taken in a digital X -ray machine and analyzed in the EcoView® software. The veins of the metacarpus and metatarsus; and the proximal, middle and distal phalanges of the forelimbs and hindlimbs of sheep and goats were identified 25-30 seconds after contrast injection. The technique error observed during the venography was the contrast perivascular extravasation. The venograms showed the vascularization in the distal region of forelimbs and hindlimbs and the communication of vessels between them. The better radiographic view to evaluate the vessels was the lateral projection. The normal venous pattern of the distal region of forelimbs and hindlimbs of sheep and goats could be observed by venography.

Resumo O exame venográfico permite diagnosticar e tratar afecções da região podal. Pode ser base de estudos sobre a administração de medicação na região do casco. O objetivo do estudo foi descrever o padrão venográfico na região distal dos membros torácicos e pélvicos de ovinos e caprinos saudáveis, bem como comparar a vascularização entre eles. Foram utilizados 10 ovinos e caprinos clinicamente saudáveis, cinco machos e cinco fêmeas de raças diferentes, com idade entre 2 a 4 anos e pesando 45 a 63 kg. Os membros torácicos e pélvicos foram submetidos à venografia contrastada da região distal. Os venogramas foram coletados por um aparelho radiográfico digital e analisados no software EcoView®. As veias da região do metacarpo e metatarso; as falanges proximal, medial e distal dos membros torácicos e pélvicos dos ovinos e caprinos foram identificadas 25-30 segundos após a injeção do contraste. O erro de técnica observado durante a venografia foi o extravasamento perivascular do contraste. Os venogramas revelaram a vascularização na região distal dos membros torácicos e pélvicos e a comunicação dos vasos entre eles. A projeção lateral foi a melhor projeção radiográfica para avaliar os vasos no venograma. O padrão venoso normal da região distal dos membros torácicos e pélvicos de ovinos e caprinos pode ser observado pela venografia.
