Chemodectoma located in left atrium in dog – 11-month survival with the use of palliative therapy
The aim of this study was to present a clinical case of chemodectoma located in the left atrium in a dog. Chemodectoma is a heart base tumor, neoplasms that occur in the proximity of major blood vessels. A presumptive diagnosis is made based on location and appearance of the tumor in echocardiography examination. In advanced diagnostics computed tomography (CT) and magnetic resonance imagining (MRI) are used. Final diagnosis is made mainly during autopsy based on histopatological examination or less commonly in veterinary medicine on a histopathological examination of the tissue taken during a biopsy or of the entire removed tumor. In literature few methods of treatment are presented, including surgery, chemotherapy and radiotherapy. In an 8-year-old male French bulldog a tumor in the left atrium was detected. The tumor filled almost the entire left atrium, additionally pericardial effusion and ascites were observed. For treatment, tarantula cubensis extract (Theranecron) was used. After the introduction of Theranecron the patient felt significantly better. Theranecron may be one of the possibilities of palliative therapy in the case of diagnosing inoperable chemodectoma.
