Aural hematomas in small ruminants - clinical features, surgical treatment and outcome

Background: Aural or auricular hematoma is an important and prevalent surgical condition in small animals practice, and commonly reported in companion pets. The condition is characterized by blood accumulation between the pinnae's dermal surface and the underlying perichondrium. In farm animals, most cases present surgical treatment with drainage of serosanguineous fluid from acute cases with clinical evolution ranging from 1 to 5 days. Therefore, the present work reports the clinical features, surgical treatment and outcome of aural hematomas in 3 small ruminants with a chronic evolution (7 to 20 days), detailing the post-surgical complications, such as wound infection and recurrence, and final cosmetic appearance of the pinnae. Cases: Upon physical examination, all animals were alert and presenting a good body condition score. Clinical alteration was restricted to a bilateral (Case 1) or unilateral (Cases 2 & 3) painless, and fluid-filled swelling, presenting doughy consistency masses within the fluid during pinna manipulation. The fluid-filled swellings were located on the concave (Case 1 - left ear & Case 2) and convex (Case 1 - right ear & Case 3) surface of the pinna. No primary pruritic disorders of the pinna were detected, and a diagnosis of traumatic aural hematoma was proposed. Due to the chronicity of the cases, surgical approach was advisable. The small ruminants underwent general anesthesia, and a linear incision over the skin overlying the hematoma was performed (Cases 1 & 2). After removal of blood and fibrin clots, the cavity was flushed and captonated size 0 nylon mattress sutures were performed on either side of the incision, in order to obliterate the dead space. Due to recurrence after 14 days, Case 2 was submitted to a modified surgical approach using a S-shaped incision combined to multiple drainage holes (MDH) using a disposable 6 mm biopsy punch. The same approach has performed in Case 3. Then, size 0 nylon mattress sutures followed by a tight protective pressure and absorbent bandage combined with an Elizabethan collar was applied. Postoperatively, Case 1 presented surgical site infection and the antibiotic was changed after bacterial culture and antibiogram results. Hospital discharge varied from 14 to 19 days' post-surgery. All animals presented some degree of ear retraction and a linear or S-shaped scar on the affected ear, but final cosmetic appearance was satisfactory to all owners. Discussion: Aural or auricular hematomas are a frequent disorder in dogs and cats clinical practice. In sheep, the few reported cases have been associated with pruritic disorders of the pinna, such as ticks infestation and sarcoptic mange. Whilst in goats, traumatic injuries, such as ear tagging and trauma from others goats, are considered the main cause, especially in breeds with pendulous ear. In our cases with chronic evolution (> 7 days), the most important clinical feature was the presence of doughy consistency masses within the fluid, suggesting matured blood and fibrin clots. A linear incision with captonated size 0 nylon mattress sutures was associated to post-surgical complications, such as wound infection and aural hematoma recurrence. Therefore, a S-shaped incision associated to creation of MDH, in order to achieve better drainage, was the chosen approach in the second surgery (Case 2) and on the subsequent patient (Case 3). To the best of our knowledge, this is the first report using the MDH approach in farm animals, that appears to be an effective treatment for chronic aural hematomas in small ruminants.

Chronic expanding hematoma secondary to excision of recurrent myxomas in a bitch

Background: Expanding chronic hematoma is a relatively common postoperative complication in humans, not in dogs, nevertheless, is important understand this condition because it may affect the animal's health. A hematoma could be formed within hours and usually stabilizes spontaneously with the reabsorption of its content. However, occasionally the hematoma slowly expands, becomes encapsulated and forms a mass, causing a chronic expanding hematoma. Possibly skin and adipose tissue are displaced secondary to trauma, causing the formation of blood-filled cysts surrounded by a fibrous capsule. The aim of this document is to present the first report of a postsurgical chronic expanding hematoma in dog. Case: A case of chronic expanding hematoma secondary to excision of recurrent myxoma in a bitch was described. Physical examination showed a hard, firm, non-mobile mass enclosed within the deep muscular layers. This mass was between the sternum and the cranial abdomen, similar to previous lesions excised by another veterinarian. Fine needle aspiration indicated the presence of blood. Radiology demonstrated that the bone-cartilage tissue was not involved. Due to the size of the mass, a skin stretching pre-suturing technique using self-adhesive tape was applied around the mass 48 h before surgery. The mass was removed with wide excision margins and portions of the affected muscles, but a large wound with great tension was created; consequently, a parallel to the wound incision and the thoraco-lumbar vertebrae was made. Six months after surgery, the animal presented recurrence of the same lesion, which was also removed. The bleeding times were within the normal range, but the animal was diagnosed with hyperadrenocorticism. After both surgeries histopathological exam revealed a hematoma, that had thrombosis and granulation tissue with fibrosis and severe panniculitis, in addition of multifocal, chronic, moderate lymphohistiocytic myositis; all these changes were compatible with a chronic expanding hematoma. Discussion: Chronic expanding hematoma is a mass that grows slowly secondary to hemorrhage and does not exhibit elements of malignancy. However, it can occasionally be confused for a soft-tissue neoplasm. It has been reported frequently in humans but not in small animals. The first case was reported in 2002: 5 puppies with a cervical hematoma classified as a chronic expanding hematoma was described. In addition, 3 cases were reported: 1 cat with perirenal chronic expanding hematoma; 1 bitch with intra-abdominal presentation, and 1 cat with this pathology on the right pelvic limb after an intramuscular injection. The etiology of chronic expansive hematoma is unidentified in dogs, nevertheless, it is stipulated that is not an inflammatory process as previously assumed, but rather a neoplastic process. As in other cases, it was difficult to determine the origin of the chronic expanding hematoma. The coagulation times and platelets count were within ranges. Similarly, it is very complicated to relate hyperadrenocorticism with chronic expanding hematoma because dogs with Cushing's disease generally present hypercoagulopathies. Myxomas are associated with endocrinopathies in humans and dogs, therefore, hyperadrenocorticism is possibly related with this neoplasia. Myxomas have an expansive growth pattern, contrasting with myxosarcomas, which are infiltrating; Although in the present case the skin mass appeared to be invasive, both macroscopical and histopathological appearance of it corresponded to a well-shaped capsule compatible with chronic expanding hematoma. In summary, to the best of our knowledge, this is the first report of a post-surgical chronic expanding hematoma in a dog.

Corticoterapia intralesional no tratamento de otohematoma em cães / Treating otohematomas in dogs with intra-lesional corticotherapy

Background: Otohematoma is common in dogs and is characterized by blood accumulation between the skin and cartilageof the outer ear. While the etiology is related to trauma, most cases have a predisposing condition. Treatment must drainthe hematoma and maintain appropriate skin apposition to the ear cartilage. Treatment can be surgical, but there are alsoconservative options such as puncture drainage, followed by intralesional injection of glucocorticoids. This alternativemethod is less invasive than surgery, with an equivalent success rate. This study aimed to describe intralesional injectionof corticosteroids for the treatment of dogs with otohematoma at a veterinary clinic.Materials, Methods & Results: Otohematoma was diagnosed and treated in 23 dogs (14 males and 9 females, weighing9.6 ± 2.7 kg) at a reference private veterinary clinic. The dogs were chemically restrained, and their ears were cleanedwith chlorhexidine. The lower face of each ear with otohematoma was then punctured with a needle coupled to a syringeto drain the liquid. Following drainage, the equipment was removed and the collected liquid volume was measured. A0.5 mg/kg dose of methylprednisolone acetate was prepared and diluted in saline (0.9% NaCl) to a volume equivalent to1/10 of the previously drained content volume from the otohematoma. The prepared solution was then injected into thedrained ear. Additionally, each patient was treated for the original cause of the otohematoma, according to conventionalprotocols. Eight animals (34.78%) had bilateral otohematoma and 15 (65.22%) presented with unilateral lesions. Leukocytosis was observed in most patients. Other laboratory alterations present in the studied dogs were thrombocytopenia,leukopenia, and anemia. Twenty (86.96%) patients presented with otitis externa. All patients were reassessed one weekafter the initial treatment, and 19 (82.60%) fully recovered. The remaining...(AU)

Aural Hematoma Secondary to Hemangiosarcoma in a Domestic Cat-Case Report.

A 7-year-old, white, domestic short hair, female cat was presented with an aural hematoma of the right pinna, which had been partially resected a year previously. A 3 × 4 cm mass, macroscopically similar to an auricular hematoma, was visible on the convex surface and a smaller vascular lesion was present on the ear margin. Cytological examination of the smaller mass was suggestive of hemangiosarcoma, and a diagnosis confirmed by histopathologic and immunohistochemical tests. Complete pinnectomy with a wide margin was performed and during the 3-year follow-up, the cat had no local recurrence or metastasis. We conclude that hemangiosarcoma should be considered as a potential differential diagnosis in white-coated cats with an unusual clinical presentation of aural hematoma.

Economic losses due to hematoma in bovine carcasses from the north central mesoregion of Paraná / Perdas econômicas decorrentes de hematoma em carcaças bovinas provenientes da mesorregião norte central do Paraná

Food security is important, and is being increasingly focused on during animal production. In bovine carcasses, we can find hematomas that are the consequences of traumas caused by several factors. These cause the extravasation of blood from vessels, causing the blood to accumulate in muscular tissues, which can then serve as a substrate for bacterial proliferation. The objective of this study was to quantify the occurrence of hematomas in bovine carcasses and to determine their degree of severity, to measure the economic impact these hematomas can cause. The slaughter of 385 animals was monitored, and 56.88% showed some type of hematoma. In injured animals, there were a total of 427 lesions, with an average of 1.94 of injuries per animal. There was a total loss of 65.7 kg of meat, with following proportional distribution: 12.32% in the front room (8.1 kg), 33.18% near the ribs and the lumbar region (21.8 kg), and 54.49% (35.8 kg) in the hindquarter. The resulting economic loss was calculated to be a total of US$ 206.66 (R$ 817.93). We conclude that the occurrence of hematoma lesions in bovine carcasses from the north central mesoregion of Paraná is responsible for economic losses.

Primary paranasal maxillary hematoma: clinical characteristics, diagnosis and surgical treatment

Background: The equine paranasal sinus have a complex anatomy and large compartiments. For this reason, deseasesthat affect these structures may develop for long periods before the animal show any clinical signs, making it difficult tostablish a definitive diagnosis and institute an adequate treatment. Usually, maxillary hematomas reports come from progression of ethmoidal hematomas, and the descriptions of primary maxillary hematomas are rare. This study aims to reportthe clinical features, diagnosis and treatment of a case of a maxillary hematoma not associated with ethmoidal turbinates.Case: An 8-year-old male horse, Mangalarga Paulista, was referred to the Centro de Apoio ao Ensino e Pesquisa FMVZUSP with history of nasal bleeding for over a year. The animal presented deformity on the right side of the face, with significant volume increase on the maxillary bone region and dull sound at percussion, in addition to great painfull sensibilitywhen palpated. The right nare had no airflow, suggesting complete obstruction of the right nasal cavity. In order to betterevaluate, endoscopic and radiographic exams were performed. At the radiographic exam, in ventrodorsal projection, itwas observed an increase of volume and radiopacity, occupying the right antimer of the nasal cavity, with left nasal septum deviation.

Avaliação Do Manejo Pré-Abate Na Ocorrência De Contusões Em Carcaças Bovinas / Evaluation Of Pre-Slaughter Management In The Occurrence Of Bruising In Bovine Carcasses / Evaluación Del Manejo Pre-Sacrificio En La Ocurrencia De Contusiones En Carcazas Bovinas

O período pré-abate tem início na propriedade no momento anterior ao embarque e segue até o momento da sangria do animal no frigorífico. Trata-se do período em que o animal é submetido a mais intensas condições de estresse físico, tais como: fome, sede, fadiga, alterações de temperatura e estresse psicológico devido sobretudo às novas condições e locais, as quais o animal não está adaptado. O manejo incorreto durante esse processo gera consequências diretas no produto final, como carne com características indesejadas, com aumento principalmente da incidência de hematomas nas carcaças. Durante a toalete da carcaça os hematomas provenientes tanto do manejo diário da fazenda, quanto os provenientes do manejo pré-abate são retirados, gerando assim um prejuízo financeiro para o proprietário. Esses hematomas são avaliados de diversas formas, mas principalmente através do tamanho, profundidade e cor, essas características podem indicar a causa e quando esse hematoma foi causado. A fim de melhorar o bem-estar dos animais e consequentemente melhorar a produção foram estipuladas as “Cinco liberdades”, que consistem em condições mínimas que os animais precisam ter acesso durante a sua criação. Em todas as etapas da criação preconiza-se o manejo adequado e calmo evitando maiores problemas na propriedade e principalmente mantendo um produto final de qualidade.

The pre-slaughter period starts in the property in the time prior to loadinguntilstunning at theslaughterhouse. It’s the moment which the animal is subjected to greater physical stress conditions as: hunger, thirst, fatigue, temperature changes, and psychological stressdue to the new conditions in which the animal is being placed. The bad handling present during this process generates direct consequences on the final product, like meat with unwanted features, and principally increase the incidence of bruising in carcasses. During the housing toilet bruising from both the daily management of the farm, as those from the pre-slaughter management are removed, thus generating a financial loss for the owner. These bruises are evaluated in several ways, but primarily by the size, depth and color, these characteristics may indicate the cause bruising and when this was caused. In order to improve animal welfare and consequently improve production were set the "Five Freedoms", which consist of minimum conditions that the animals need for their creation.

Epidemiology and anesthetic risk in dogs with aural hematoma / Epidemiologia e risco anestésico de cães portadores de otohematoma

Background: Otohematoma or aural hematoma in dogs is blood pooling within the ear cartilage plate, and stems from several causes (ear infections, ectoparasites and others). The formation of hematoma is by vascular injury, causing bleeding, generated by self-injury. This disease occurs especially in dogs of pendulous ears, and the concave surface of the ear is considered as the most frequent. The therapy to correct the lesion can be a clinical procedure; however, surgical drainage is the treatment of choice. This work aims to record the epidemiological aspects related to aural hematoma in dogs, as well as classify such patients as to the physical condition and anesthetic risk. Materials, Methods & Results: Twenty five dogs with aural hematoma submitted to surgical procedure were followed. During the data collection period (seven months), surgery to correct aural hematoma represented 19% of surgeries performed in dogs (total of surgeries: 474). The percentage of canine breeds affected was: mixed breed (64%; 16/25), german shepherd (24%; 6/25), labrador (4%; 1/25), waimaraner (4%; 1/25) and daschund (4%; 1/25). Most occurrences were observed in females aged 3-12 years. Most of the animals showed only one pina affected (96%; 24/25), and 52% (13/25) had hematoma in the right and 44% (11/25) in the left ear. Some of the patients had no hematologic abnormalities (48%; 12/25) [...]

Quantity, location, and description of bruises in beef cattle slaughtered under sanitary inspection

Background: The distance traveled by trucks carrying cattle from farm to slaughterhouse can affect the resultant qualityof beef due to the occurrence of injuries en route. The types of injuries that can occur vary according to the depth, size,location, and quantity of the injuries. Staining can be used to determine the age of the lesions and estimate the time whenthe injury occurred, thereby providing information that can be used to make changes in the trucking of cattle in order todecrease or eliminate the injuries. The effects associated with three transportation distances when hauling 20 cows perlivestock truck were investigated. The collected data focused on the age, depth, size, quantity, and location of bruises foundon beef carcasses slaughtered in the mesoregion of Triângulo Mineiro and Alto Paranaíba, Brazil, in January of 2012.Materials, Methods & Results: A total of 320 cows were randomly divided into three groups according to the distancetraveled via livestock truck from the farm to the slaughterhouse. Each truck carried 20 cows. In groups A (n = 140), B (n= 40), and C (n = 140), the cattle traveled 50 to 60 km, 90 to 110 km, and 140 to 166 km, respectively. Any extant contusions were visually observed on the production line after skinning, and relevant data were recorded using the respectiveanimal’s identifi cation tag as the identifi er and analyzed. Of the 320 animals analyzed, 285 (89.06%) had one or morelesions (i.e., a total of 682 bruises in the entire sample), which is consistent with the results of similar studies found inthe literature. Distances did not statistically infl uence the amount of bruising. For all distance conditions, the anatomicalsite on the cow with the highest incidence of injuries was the hindquarter (71.41%), and the lowest incidence was the loin(4.55%). No association between distance and location of bruises was observed. For all groups, a majority (48.09%) of...

Otohematoma consiste no acúmulo de sangue entre a cartilagem e a pele do pavilhão auricular, decorrente de fraturas na cartilagem auricular e ruptura de vasos sanguíneos causando incomodo e dor. Ocorre com frequência em cães, porém é incomum em gatos. Normalmente, OH estão associadas aos processos traumáticos, infecções bacterianas, parasitárias ou fúngicas do ouvido, entretanto sua etiologia não está totalmente esclarecida, uma vez que nem todos os animais apresentam OH na presença de otite, mesmo em situações de prurido intenso.

Aural hematoma is a blood accumulation between the ear cartilage and skin, as the result of auricular cartilage fractures and ruptured blood vessels causing discomfort and pain. It commonly occurs in dogs but rarein cats. Typically, OH are associated with traumatic, parasitic bacterial infections, fungal ear process, however, its etiology is not entirely clear, since not all animals have OH in the presence of otitis media, even under heavy itching. In this paper a review about the disease and is an unusual case of aural hematoma occurs in a cat.

Oto-hematoma (OH) es la acumulación de sangre entre el cartílago y la piel de la oreja, como el resultado de las fracturas del cartílago auricular y ruptura de vasos sanguíneos causando malestar y el dolor. Se produce con frecuencia en los perros, pero es poco común en gatos. Típicamente, OH están asociados con proceso traumático, bacterianas parasitarias infecciones, hongos en el oído, sin embargo, su etiología no está totalmente claro, ya que no todos los animales tienen OH en presencia de otitis media, incluso bajo fuerte picor. En este trabajo se hace una revisión acerca de la enfermedad y se presenta un caso inusual de hematoma aural en un gato.

Quantity, location, and description of bruises in beef cattle slaughtered under sanitary inspection

Background: The distance traveled by trucks carrying cattle from farm to slaughterhouse can affect the resultant qualityof beef due to the occurrence of injuries en route. The types of injuries that can occur vary according to the depth, size,location, and quantity of the injuries. Staining can be used to determine the age of the lesions and estimate the time whenthe injury occurred, thereby providing information that can be used to make changes in the trucking of cattle in order todecrease or eliminate the injuries. The effects associated with three transportation distances when hauling 20 cows perlivestock truck were investigated. The collected data focused on the age, depth, size, quantity, and location of bruises foundon beef carcasses slaughtered in the mesoregion of Triângulo Mineiro and Alto Paranaíba, Brazil, in January of 2012.Materials, Methods & Results: A total of 320 cows were randomly divided into three groups according to the distancetraveled via livestock truck from the farm to the slaughterhouse. Each truck carried 20 cows. In groups A (n = 140), B (n= 40), and C (n = 140), the cattle traveled 50 to 60 km, 90 to 110 km, and 140 to 166 km, respectively. Any extant contusions were visually observed on the production line after skinning, and relevant data were recorded using the respectiveanimals identifi cation tag as the identifi er and analyzed. Of the 320 animals analyzed, 285 (89.06%) had one or morelesions (i.e., a total of 682 bruises in the entire sample), which is consistent with the results of similar studies found inthe literature. Distances did not statistically infl uence the amount of bruising. For all distance conditions, the anatomicalsite on the cow with the highest incidence of injuries was the hindquarter (71.41%), and the lowest incidence was the loin(4.55%). No association between distance and location of bruises was observed. For all groups, a majority (48.09%) of...(AU)

Occurrence of carcasses bruises of beef cattle transported by two distances / Ocorrência de hematomas em carcaças de bovinos transportados por duas distâncias

This study aimed to determine the occurrence of beef cattle carcasses bruises on transported by two distances and slaughtered in northern Mato Grosso State. In total, 624 male animals were evaluated 30 to 36 months come from varying distances to slaughterhouse, with 352 animals originating from within 200km and 272 animals above 200km. To review the injuries on carcasses, followed the criteria described by AUS -MEAT (2005), the lesions were classified according to their location in the carcass (forequarter, spare ribs and hindquarter). The relationship of lesions per group increased with greater distance of transport, being 43.75% and 95.58% of animals with carcass bruised, respectively, to less and more than 200km of trip. When analyzed the region of the hematoma, observed 7.6 e 17.6 carcass bruises in the forequarter regions (P = 0.035) and 30,6 e 101,0 in the hindquarter regions (P = 0.009) to near and longer distance, respectively. It is concluded that the transport distance to slaughter increases the number of carcass bruises, mainly, in the hindquarter.

O objetivo foi determinar a ocorrência de hematomas em carcaças de bovinos transportados por duas distâncias e abatidos no norte do estado do Mato Grosso. Foram avaliados 624 bovinos machos de 30 a 36 meses oriundos de distâncias variadas até o frigorífico, sendo 352 animais oriundos de distâncias menores que 200km e 272 animais transportados por mais de 200km. Para avaliação dos hematomas nas carcaças, seguiu-se o critério descrito pela AUS-MEAT (2005), sendo as lesões classificadas de acordo com a sua localização na carcaça (traseiro, dianteiro ou costado). A relação de hematomas por grupo aumentou com a maior distância de transporte, sendo 43,75% e 95.58% de animais com hematomas para distâncias menores e maiores que 200 km, respectivamente. Quando analisada a região do hematoma, verificou-se 7,6 e 17,6 observações na região do dianteiro (P= 0,035) e 30,6 e 101,0 observações na região do traseiro (P=0,009) para distâncias menores e maiores que 200km, respectivamente. Portanto, a distância do transporte de bovinos até o abate teve influência sobre a quantidade de hematomas apresentados, principalmente na região do traseiro.

Estudo retrospectivo do otohematoma em cães atendidos em um hospital veterinário universitário / Retrospective aural hematoma in dogs presented to a University Veterinary Hospital

O otohematoma canino é um caso clínico comum na rotina da clínica médica de pequenos animais. Os principais fatores predisponentes correspondem a raça, sexo, idade, anatomia do pavilhão auricular e presença de outras afecções concomitantes. O presente trabalho objetivou a caracterização epidemiológica do hematoma auricular na espécie canina. Realizou-se um estudo retrospectivo utilizando os dados recolhidos das fichas clínicas de 55 cães com otohematoma, atendidos no Hospital Veterinário da Universidade Federal do Piauí, no período compreendido entre janeiro de 2007 a dezembro de 2008. O sexo masculino foi o mais acometido, com 62% dos casos. A faixa etária de maior representação variou de 7 a 8 anos de idade (29%). Os animais Sem Raça Definida possuíram destaque em relação à frequência de otoematoma (41%), seguindo-se dos indivíduos da raça Pastor Alemão (34%) e Fila Brasileiro (5%). A maioria dos pacientes apresentou um peso corporal superior a 20 Kg (71%). Os resultados obtidos sugeriram que o hematoma auricular canino apresentou alguns fatores de risco, como a idade adulta e o porte elevado do animal.

The otohematoma canine is a common clinical case in routine clinical care of small animals. The main predisposing factors correspond to race, sex, age, anatomy of the ear and the presence of other concomitant conditions. This study aimed to characterize the epidemiological auricular hematoma in dogs. We conducted a retrospective study using data collected from the medical records of 55 dogs with otohematoma treated at the Veterinary Hospital of the Federal University of Piauí, in the period from January 2007 to December 2008. The male was the most affected, with 62% of cases. The age group most represented ranged from 7 to 8 years of age (29%). The animals possessed undefined breed featured in the frequency of otohematoma (41%), followed by the German Shepherd individuals (34%) and Fila (5%). Most patients showed a body weight above 20 kg (71%). The results suggest that the canine auricular hematoma presented some risk factors, such as age and size large adult animal.
