RESUMO
Two dogs with anorexia and rapid weight loss were referred to our hospital due to a right renal mass and several pulmonary nodules. Both dogs underwent needle core biopsy of the mass, followed by transarterial chemoembolisation of the renal mass. A catheter was inserted from the femoral artery and advanced into the right renal artery. A suspension of carboplatin (100 mg/m2 ) and equivalent lipiodol was administered via the inserted multipurpose catheter. Immediately after, under fluoroscopic guidance, pulse injections of small amounts of gelatin particles (diameter 1 mm) dissolved in iohexol were administered until complete embolisation of the renal artery. Histopathologic diagnosis was renal cell carcinoma in both dogs. Clinical signs improved for 134 and 358 days after transarterial chemoembolisation. In addition, postoperative radiographs demonstrated a decrease in the tumour size. The dogs died 215 and 525 days after the initial evaluation, respectively. As a palliative treatment, transarterial chemoembolisation might help reduce the tumour volume and improve the quality of life in dogs with renal cell carcinoma and distant metastases.

A 9-year-old spayed female crossbreed cat with chief complaints of anorexia and hypersalivation had high serum concentrations of ammonia and fasting and postprandial total bile acid. Therefore, she was referred to our hospital. On the first evaluation, haematology, serum chemistry, radiography and ultrasonography findings suggested that she had a congenital portosystemic shunt. CT revealed a shunt vessel from the left gastric vein to the left pulmonary vein. During median celiotomy and sternotomy, gross findings and mesenteric portography revealed abnormal vessel shunting from the left gastric vein to the left pulmonary vein. Complete ligation of the shunt vessel was achieved. She recovered without any complications. Postoperative serum chemistry revealed that ammonia and total bile acid levels decreased to within the reference intervals. This report is the first to describe the clinical features and surgical outcome of a cat with a congenital portopulmonary shunt.
