Hemangiosarcoma is characterized by being a malignant neoplasm originating from the mesenchymal tissue of endothelial cells, being an important measurement in dogs, as it manifests itself in several organs, including the heart, in a primary or secondary way (through metastasis). In the heart, this disease can be observed in the walls of the right atrium, and, eventually, in the right ventricle. Cardiac hemangiosarcoma may have clinical signs, mainly cardiac tamponade, right heart failure, pericardial effusion and cardiac arrhythmia, however, such signs may vary according to the size of the tumor. In relation to etiopathogenesis and oncogenesis, they have not yet been well clarified, where their origin indicates that they are from bone marrow precursor endothelial cells, and it is also worth highlighting the association with hereditary predisposition. Furthermore, its diagnosis is difficult to conclude, as the changes are not well visualized in exams, such as radiography, laboratory and cytological analyzes of the pericardial fluid, due to the difficult cell differentiation in the effusion. Therefore, definitive diagnosis includes thoracotomy or thoracoscopy, together with biopsy. Regarding treatment, surgical or chemotherapy methods can be taken, such as performing exploratory thoracotomy to resect the tumor mass, respecting safety margins. While chemotherapy includes the interaction of vincristine, doxorubicin and cyclophosphamide, it is more advisable to administer it immediately after the surgical procedure. Therefore, the aim of this work was to highlight and analyze clinical and pathological aspects of this disease, taking into account literary data related to cardiac hemangiosarcoma in dogs.
Encarceramento nefroesplênico de cólon ascendente esquerdo em equinos : revisão de literatura

Colic syndrome in horses is characterized as pain of acute abdominal origin, which can originate from various diseases in abdominal organs, however, in the vast majority of cases, the origin of the pain is disorders in the gastrointestinal tract (GIT). Among these diseases of the GIT is the displacement of the left ascending colon and its incarceration over the nephrosplenic ligament. This displacement is characterized by the entrapment of the pelvic flexure in the nephrosplenic ligament, and the main predisposing factor for this to occur are the muscles themselves. anatomical characteristics of the region. This condition can lead to mild, moderate or severe pain, causing physical changes, mainly in heart rate, respiratory rate and intestinal motility pattern. Diagnostic methods for nephrosplenic incarceration include the association of findings on physical examination, transrectal palpation and transabdominal ultrasound examination. However, it is worth highlighting that, in certain cases, only the surgical procedure confirms the diagnosis. In the case of an established clinical diagnosis, the main drug therapy applied to these cases is the administration of epinephrine in the form of an infusion, in an attempt for this alpha-2 adrenergic agent to lead to splenic contraction, and the ascending colon to return to its normal anatomical position. . In some cases, this attempt at splenic contraction does not produce positive results, leaving the surgical procedure as the only treatment. The objective of this work is to address, through a literature review, the main aspects of the nephrosplenic entrapment in horses, through a clinical and surgical approach taking into account tells current literary data.
Megaesôfago secundário a persistência do quarto arco aórtico direito em felino: Relato de caso

Persistence of the fourth right aortic arch is characterized by being a congenital vascular ring anomaly most commonly observed in dogs, considered rare in cats, comprising 95% of all vascular ring anomalies found in small animals. This condition results from malformations arising from changes in the embryogenesis of the aortic arches, where the right aortic arch persists in relation to the left aortic arch, leading to esophageal stenosis and, consequently, megaesophagus. The most evident clinical signs are regurgitation, weight loss, excessive appetite, apathy and discomfort after meals, in addition to dehydration and weakness, especially in puppies, in which dry food has recently been introduced. Respiratory signs may be associated with secondary aspiration pneumonia, due to megaesophagus. The diagnosis can be obtained through the analysis of clinical signs together with imaging tests, such as computed tomography, magnetic resonance imaging and simple or contrast radiography of the cervicothoracic region, where esophageal dilatation is visualized mainly with the contrast medium. Treatment is performed through a surgical procedure together with adjustment of dietary management, with a reserved prognosis, according to the clinical picture of each individual. Thus, the present study aims to describe the case report of persistent fourth aortic arch with secondary megaesophagus in a feline, in which the surgical procedure was performed as a treatment method.
Retículo esplenite traumática associada á peritonite em bovino: Relato de caso

The ingestion of foreign bodies by ruminants is the result of non-selective feeding, the anatomy of the fore-stomachs and the presence of sharp objects in pastures. Traumatic reticulo-splenitis is a disease with low frequency in ruminant clinical practice. It occurs due to the ingestion of sharp foreign bodies, which causes perforation of several organs in the abdominal cavity. The proximity of the reticulo-splenitis to several organs, associated with the presence of sharp objects in pastures and feeders are important factors to be analyzed, which cause several pathological processes, including traumatic reticulo-pericarditis, traumatic reticulo-peritonitis, traumatic reticulo-hepatitis and traumatic reticulo-splenitis. There are no characteristic clinical signs of traumatic reticulo-splenitis, nor specific diagnostic methods, where the spleen of cattle, for example, cannot be examined through transrectal palpation. When ingested by the animal, the sharp object follows the flow of the food bolus and remains trapped in the reticulum, where, through physiological contraction, it can perforate the organs adjacent to it. After this, the object can perforate other organs, carrying microorganisms to the site of the injury, causing an infection and malfunction of the organ. Therefore, the present study aims to report a case of traumatic reticulum splenitis in a bovine.
