This case report discusses the successful surgical resection of cardiac hemangiosarcoma in a dog using an articulated surgical stapler. Cardiac tumors, particularly hemangiosarcomas, have a poor prognosis. Recommended treatment involves surgical removal of the primary tumor, along with chemotherapy. However, the use of staples for cardiac tumor resection has not yet been extensively documented in the veterinary literature. A 10-year-old dachshund with pericardial effusion underwent surgery to remove a right atrial mass. An articulated linear cutting stapler was used for tumor resection. The patient experienced chylothorax as a complication but recovered well. However, the patient later developed respiratory symptoms and died, most likely due to aspiration pneumonia. The surgical stapler provided stability, convenience, and a shorter surgical time during tumor resection. Surgical resection combined with chemotherapy improves the survival of dogs with cardiac hemangiosarcoma. The stability and adjustability of the stapling device make it advantageous for cardiac tumor resection. Although complications, such as chylothorax, can arise, appropriate management can lead to positive outcomes. This case report demonstrates the feasibility and safety of using an articulated surgical stapler for cardiac tumor resection in dogs. Insights from this case can guide future research and clinical practice.

원발성 심장종양은 드물며 원발성 악성 심장종양은 더 드물지만 이중 맥관육종은 다른 종양보다는 흔한 편이다. 하지만 수술적 절제가 어려운 것으로 알려져 있는데 이는 환자의 증세가 비특이적이며 진단시 이미 종양의 침범이 진전된 상태가 대부분이기 때문이다. 보고자는 15세 남자에서 수술중 시행한 조직학 검사에서 원발성 심장 맥관육종을 확진하고 우심방을 거의 막고 있는 종양을 제거하였다. 환자는 수술후 15일후에 특별한 문제없이 퇴원하였다.

We detected two cases of right atrial angiosarcoma that had a similar appearance on imaging studies. Although the surgical findings were similar for the two patients, one had a clear resection margin, while the other had tumor cells in the resection margin on frozen biopsy. We suggest that preoperative data on magnetic resonance imaging and computed tomography in patients with angiosarcomas may not predict the exact extent of surgical resection or prognostic outcomes.

An adult male dog was presented for hemorrhagic pericardial effusion. Echocardiography and computed tomography revealed nodule-like lesions on the pericardium. Cytology of pericardial effusion and excisional pericardial lesions indicated neoplastic effusion. Histopathology indicated an inflamed neoplasm with a primary differential diagnosis of hemangiosarcoma and malignant mesothelioma (MM). Immunohistochemistry showed that atypical cells were positive for cytokeratin and vimentin, but negative for CD31, strongly favoring pericardial MM. Postoperative NT-proBNP level remained increased, which led to the administration of epirubicin to minimize potential cardiotoxicity. During the 4 cycles of epirubicin treatment, a total cumulative dose of 108 mg/m² was administrated and no effusion recurrence was observed. After a month post-completion of chemotherapy, however, pleural effusion was detected with cardiac masses. The owner requested no further diagnostic investigations and chemotherapy. Due to deteriorating conditions, the dog died 132 days after the first presentation. Our case is the first notable attempt to treat canine malignant mesothelioma with epirubicin, providing the clinicopathologic, diagnostic routine, and clinical course of the affected dog.
