Background: Malignant pleural mesothelioma (MPM) is a neoplasm with low incidence in small animals, and the possible causes are poorly elucidated but may be related to contact with asbestos. In the thoracic cavity, MMP can be localized or generalized to all cavity structures, and its clinical signs depend on this localization. Although some alternative therapies are being discussed, few studies are conclusive, with surgical intervention as the leading therapeutic option. Given this context, this report aimed to describe a case of MMP located in the mediastinum of a bitch treated with radical excision through mediated sternotomy. Case: A 7-year-old bitch of the Shar-pei breed was referred for care due to progressive weight loss and intense dyspnea. During the physical examination, dyspnea and muffled lung sounds were noted. The patient underwent hemodialysis, which showed neutrophilic leukocytosis. An abdominal ultrasound was also performed and revealed mild abdominal effusion, and chest radiography revealed an extensive tumor covering the entire chest cavity. Thoracocentesis was performed, and the material analyzed was a malignant exudate; the patient was referred to median sternotomy for exploratory purposes, and afterward, total macroscopic extirpation of the tumor was performed. A sample was sent for histopathology, and malignant mesothelioma was confirmed. The patient was discharged after 8 days of hospitalization with home treatment and did not return to the hospital. Upon contacting the guardian, we were informed that the animal had died 154 days after the procedure due to unknown causes. Discussion: Malignant pleural mesothelioma affects humans and animals; it is associated with the risk factor of contact with asbestos and the use of flea antiparasitic drugs. In small animals, its incidence is rare, albeit mesotheliomas have been reported in wild and large animals. The clinical signs are related to the location of the neoplasm. When it is located in the thoracic region, dyspnea, muffled lung sounds, cyanosis, and pleural effusion are observed in most cases. Diagnosis is usually late and incidental, although some tests, such as ultrasonography, magnetic resonance imaging, tomography, radiography, and needle biopsy, can help in the diagnosis. Histopathology is the exam of choice for definitive diagnosis, as it helps one observe the proliferation of neoplastic mesothelial cells, atypical mitosis figures, and marked cellular pleomorphism. Many therapeutic options have been discussed, including chemotherapy, immunotherapy, and anti-tumor immunization, although there is little scientific proof of their efficacy in animals. The current treatment of choice is tumor excision by surgical procedure with a palliative objective since the prognosis of the disease is unfavorable. Minimally invasive video surgery has been gaining more and more space in veterinary medicine and has proven successful in numerous cases of thoracic masses. In the present report, we chose to perform median sternotomy for total excision due to the extension of the mass that occupied the thoracic cavity practically in its entirety. Further research should be conducted to help in palliative treatments and increase the survival of patients with mesotheliomas, given that most studies are done in humans and not animals. We conclude that median sternotomy is still the therapeutic option of choice for the palliative treatment of patients with extensive thoracic pleural mesotheliomas.

A six-month-old male Brazilian Terrier with persistent cough and dyspnea was diagnosed with intrathoracic tracheal collapse and pneumonia after chest radiographics. The medical treatment was performed, and an extraluminal nitinol prosthesis was placed through thoracic access. The dog did not presented recurrence of dyspnea or pneumonia for four years after the surgical procedure. Placement of the extraluminal prosthesis with the thoracic approach effectively stabilized intrathoracic tracheal collapse without causing any structural damage in the thoracic region. Therefore, this is the first report of a successful use of this prosthesis with an intercostal approach in dogs for intrathoracic trachea collapse.
Um cão macho, da raça Terrier Brasileiro de seis meses de idade, com dispnéia e tosse persistente foi diagnosticado com colapso traqueal intratorácico e pneumonia após estudo radiográfico de tórax. Foi instituído tratamento médico e realizada toracotomia para a implantação de prótese traqueal extraluminal de nitinol. O animal não manifestou dispneia ou pneumonia durante os quatro anos posteriores ao procedimento. A implantação da prótese extraluminal através da toracotomia foi eficaz para o tratamento do colapso traqueal intratorácico, sem provocar danos estruturais na região torácica. Desta forma, este é primeiro relato da utilização bem-sucedida deste tipo de prótese, a partir da abordagem intercostal, no tratamento de cães com colapso traqueal intratorácico.

Background: Pulmonary bullae are thin-walled cavitary lesions within the subpleural parenchyma. They are a result of thedestruction, dilatation and coalescence of bordering alveoli and their rupture is the most common cause of pneumothoraxin dogs. Radiographic and CT imaging are excellent tools for identifying and quantifying pneumothorax. Surgical treatment is considered standard for treatment of pneumothorax consequential to pulmonary bullae. The aim of this report wasto describe a case of pneumothorax secondary to pulmonary bullae in a dog.Case: A 5-year-old male crossbreed dog, weighing 11.5 kg, was presented to the Uberabas Veterinary Hospital due to becoming easily tired in the previous 3 weeks, and its worsening in the last 2 days by presenting panting. The dogs guardiandid not witness any traumas, but informed that the animal resided with other 14 dogs and also that it frequently collidedthe thorax against the door when it came down from the bed. Physical examination showed diaphragmatic breathing,inspiratory dyspnea and stridor lung sound. Thoracocentesis revealed presence of air in the pleural cavity and pneumothorax. Radiographic images confirmed this condition. The dog stayed in the hospital and chest drains were placed. Sincethe amount of sucked air did not reduce with time and due to the emergence of subcutaneous emphysema, the dog wentthrough exploratory thoracotomy that revealed impairment of the right caudal lung lobe, proceeding to lobectomy. Thedog stayed in the hospital with chest drains until the contents of the suctions reduced significantly. With the removal ofthe drains, the dog was sent home and had a full recovery. Histopathology of the impaired lung revealed pulmonary bullae.Discussion: The dog from this report presented clinical signs consistent with pneumothorax, such as dyspnea, diaphragmaticbreathing and exercise intolerance. Radiography of the chest region revealed...

ABSTRACT Purpose To describe an unpublished experimental model of descending thoracic aortic aneurysm in pigs. Methods Ten Landrace female pigs aged 10 to 12 weeks old and with initial weights from 17 to 25 kg were anesthetized and their descending thoracic aortas exposed by fifth intercostal space left thoracotomy. The thoracic aorta was isolated. A 2-cm wide × 2-cm long patch of ready-made bovine pericardium was sewn onto the left anterolateral side of the aorta. After three weeks' follow-up, a control aortography was taken, and the animals were euthanized. The segment of thoracic aorta containing the aneurysm and the adherent tissues were explanted en bloc. The specimens were stained for histological examination. Results One hundred percent of the animals survived the procedure, and after sacrifice a patent aneurysm was observed in all of them. There were no defects on the suture lines. Weight gain during follow-up was normal. All specimens exhibited intense adventitial reaction with myofibroblasts. There were no complications related to the thoracotomy. Conclusions The descending thoracic aortic aneurysms induced experimentally appear to be stable, were of easy execution, with null mortality and no influence on the animals' normal development. Furthermore, they have similar characteristics to those observed in human degenerative aneurysms.

Dioctophyme renale is a parasite of the nematode class that can infect various species, including humans and dogs. Usually, the parasite migrates to the right kidney of the definitive host. Although, aberrant migrations have been previously reported, they mainly occur without clinical manifestations. No reports of dyspnea secondary to D. renale infestation has been found in the reported literature. The aim of this paper is to report intense respiratory distress caused by the presence of the parasite in the thoracic cavity of a dog. Radiographic images revealed multiple circular structures with a cavity with a radiopaque, thick contour in the thorax, which raised the suspicion of pulmonary bullae. Ultrasound examination revealed nematode infestation in the right kidney, scrotum, and thoracic cavity. Subsequently, right nephrectomy, orchiectomy and trans-sternal thoracotomy were performed to remove the parasites. The patient exhibited recovery after the procedures.(AU)
Dioctophyme renale é um parasita da classe de nematoda que pode infectar diferentes espécies, incluindo humanos e cães. Normalmente, o parasita migra para o rim direito do hospedeiro definitivo. Embora migrações erráticas tenham sido relatadas anteriormente, estas geralmente ocorrem sem manifestações clínicas. Não foram encontrados relatos de dispnéia secundária à infestação de D. renale. O objetivo deste trabalho é relatar a presença do parasita na cavidade torácica de um cão, causando angústia respiratória. As imagens radiográficas revelaram a presença de múltiplas estruturas circulares com aspecto de cavidade e contorno espesso radiopaco no tórax, o que suscitou a suspeita de bullae pulmonar. O exame de ultra-som foi determinante na revelação de infestação múltipla por nematódeos, no rim direito, escroto e cavidade torácica. Posteriormente, como medida terapêutica, foram realizadas os procedimentos de nefrectomia direita, orquiectomia e toracotomia transesternal para remoçãodos parasitas. O paciente evoluiu clinicamente bem após os procedimentos.(AU)

Tracheal foreign bodies are rare emergency events. Several noninvasive methods are described for removal, such as bronchoscopy combined with appropriate grasping equipment or Foley catheter and forceps guided by fluoroscopy. However, complications can occur like pneumothorax, pneumomediastinum and irresponsive dyspnea as well as failure. Thus, pre-sternal tracheotomy combined with endoscopy or thoracotomy are attempted. Female cat, 1 year old, 1.6 kg had diagnosis of foreign body (0.7 x 0.5cm) with morphology of bird cervical vertebra at carina area, presenting one week of dyspnea, worsening with radiographic exam. It was performed emergency thoracotomy at left fifth intercostal space, followed by tracheotomy between the tracheal rings immediately cranial to the carina, allowing forceps removal. No foreign body was observed at radiograph after eight days and the patient was clinically well. Although, less invasive methods are preferable, they are not always available and they are not free from failures, leading to emergency tracheotomy as described in the present case report.

Apresentava há uma semana, dispnéia, piorando durante exame radiográfico. Foi realizado toracotomia de emergência no quinto espaço intercostal esquerdo, seguida de traqueotomia entre os anéis traqueais imediatamente cranial à carina, permitindo remoção por fórceps. Após oito dias, foi realizada radiografia controle e o paciente apresentava-se clinicamente bem. Embora, métodos menos invasivos sejam preferidos, não são isentos de falhas, necessitando toracotomia emergencial como a descrita no presente relato.

Um cão, sem raça definida, de seis anos de idade foi encaminhado após episódio de trauma torácico por mordedura, com posterior aumento de volume em região, para a realização de exame radiográfico torácico, devido à tosse seca após esforço físico ou posicionamento em decúbito dorsal. Foi evidenciada uma protrusão pulmonar através do quinto espaço intercostal esquerdo por meio das radiografias. Foi realizada a toracotomia intercostal com ressecção de porção cranial do lobo pulmonar cranial esquerdo e correção da eventração. As radiografias torácicas pós-operatórias confirmaram expansão normal do lobo cranial esquerdo remanescente. A eventração de lobo pulmonar intercostal deve ser considerada diagnóstico diferencial nos casos de aumento de volume torácico e episódios de trauma.
A mixed breed dog, six years old was referred, after an episode of thoracic trauma bite, with posterior swelling in the thoracic region, to perform chest radiographs due to dry cough after physical exertion or dorsal position. Through radiographs, pulmonary protrusion through the fifth left intercostal space was observed. Thoracotomy and resection of cranial portion of the left cranial pulmonary lobe and eventration repair were performed. Postoperative chest radiographs confirmed the normal expansion of the remaining left cranial lobe. The intercostal eventration should be considered a differential diagnosis in cases of increased thoracic volume and episodes of trauma.

Background: Vascular ring anomaly is considered a hereditary change. It occurs when the fourth right aortic arch persists instead of the fourth left aortic arch, forming a vascular ring that compress the esophagus causing esophageal dilatation cranial to the compression site. Diagnosis is based upon anamnesis, physical examination, clinical signs and complementary exams (radiograph, complete blood count and biochemical tests). The clinical treatment is inadequate, since the dilatation persists and tends to progress causing irreversible tissue injury. Surgical correction is indicated and consists of the arterial ligament resection and correction of the esophageal stenosis. Case: The objective of the current study is to report two case of persistence of right aortic arch in two cats referred to the Veterinary Hospital of the Federal University of Santa Maria. On physical examination the patients were alert, in good nutritional status, adequately hydrated and presented normal colored mucous membranes. Each animal underwent radiography and esophagogram with barium sulphate. The exam demonstrated partial esophageal dilation cranial to the cardiac silhouette, suggestive of vascular ring anomaly. An exploratory thoracotomy was performed in order to achieve the definitive diagnosis. The arterial ligament was resected and esophageal stenosis corrected. Anesthesia, surgery and the [...]

In physical examination expiratory dyspnea, abdominal breathing and muffled lung sounds (mainly in the left lower lung field) was observed. In the chest radiograph a radiopaque structure (9.5 x 7.5 cm) was visualized in the left lower lobe and the trachea was shifted to the right. Front to the findings, the animal was referred for thoracotomy with rib resection to lobectomy of the left lower lobe. In surgery, was performed incision skin/musculocutaneous parallel to the seventh left rib extending from the proximity of the costovertebral articulation to the sternum. After incision and dissection of the muscle layer, the periosteum of the seventh rib was incised on the lateral surface of the middle rib. Then sectioned rib with shear and periosteum together with the parietal pleura with the...

The occurrence of a tracheal foreign body in a three-month-old male Poodle referred to a Teaching Veterinary Hospital due to acute coughing, gagging and nausea is reported. A bronchoscopy under general anesthesia was performed in order to obtain a diagnose. During the bronchoscopy a foreign body (maize popcorn) was observed in the intrathoracic trachea. The surgeon attempted to remove it by endoscopy, but no success was achieved. Therefore, an open procedure was performed and the foreign body removed. The patient progressed satisfactorily after the thoracotomy.(AU)

PURPOSE: To evaluate different approaches performed to obtain a more significant esophageal length. METHODS: An experimental model using 28 cadavers was conceived. Randomized groups: Group A (n=10) underwent laparotomic transhiatal approach; Group B (n=9) which differed from the first in the conduction of a wide phrenotomy and Group C (n=9) esophageal dissection was performed through a left anterolateral thoracotomy. RESULTS: Final length variations for Group A were 2.12cm and 3.29cm and for Group B 3.24 cm and 3.66cm, without and with esophageal traction, respectively. In Group C length gain observed was 3.81 cm. The mediastinal dissections conducted through the hiatus was considered the procedure that produced the better esophageal mobilization, and the association of wide phrenotomy significantly improved the results. CONCLUSION: The mediastinal dissection was the most effective to improving gain in abdominal esophagus. When toracotomy and laparotomy were compared, no significant differences were observed in the outcome.(AU)
OBJETIVO: Avaliar diferentes procedimentos realizados para obtenção de um ganho mais significativo no comprimento esofágico. MÉTODOS: Um estudo experimental utilizando 28 cadáveres foi realizado. Randomização dos grupos: Grupo A (n=10): Submetido à abordagem laparotômica trans-hiatal; Grupo B (n=9): Diferente do primeiro apenas pela realização de uma frenotomia ampla; e Grupo C (n=9): A dissecção esofágica foi realizada por uma toracotomia anterior esquerda. RESULTADOS: A variação final do comprimento para o Grupo A foi 2,2 cm e 3,29 cm e para o Grupo B 3,24cm e 2,66cm, medidas na ausência e presença de tração esofágica, respectivamente. No Grupo C o ganho de comprimento observado foi de 3,81 cm. A dissecção mediastinal conduzida através do hiato foi considerada o procedimento de melhor mobilização esofágica e a associação de uma ampla frenotomia levou a uma significativa melhora nos resultados. CONCLUSÃO: A dissecção mediastinal foi a mais efetiva para promover o aumento do esôfago abdominal. Quando comparadas toracotomia e laparotomia, nenhuma diferença significativa foi observada no desfecho do estudo.(AU)
