We performed preoperative hemodilutional autologous blood collection and transfusion in 42 dogs and cats undergoing standby surgery with a high risk of intraoperative bleeding. The protocol was developed based on the Japanese Society for Autologous Blood Transfusion guidelines. There were no serious adverse events associated with hemodilutional autologous blood collection and transfusion, and the procedure was safe. In addition, hemodilutional autologous blood Donation/transfusion was considered helpful because some patients were able to avoid the use of allogeneic blood transfusion.

A 9-year-old castrated male domestic cat with sudden onset of extarahepatic biliary obstruction underwent cholecystoduodenostomy. A simultaneous liver biopsy with immunohistochemistry led to a diagnosis of large granular lymphocytic (LGL) lymphoma with hepatocytotropism, which was considered as primary hepatic disease from the subsequent clinical course. Hyperbilirubinemia temporarily improved after surgery but relapsed over the next month. Treatment with L-asparaginase or ACNU resulted in clinical improvement twice, but the cat died of relapse on Day 299 (postoperative day 294). This is the first report of a treated case of feline LGL lymphoma with hepatocytotropism.

An 8-year-old, castrated male, domestic cat presented with acute dyspnea due to a tracheal mass caudal to the larynx. Debulking surgery via a tracheotomy immediately improved her respiratory status, and the cat was discharged on the same day. The resected mass was diagnosed as a diffuse large B-cell lymphoma by histopathology, immunostaining and clonality analysis. Based on cytology, COP therapy (16 times, 5 cycles) was initiated on the day of surgery, followed by doxorubicin treatment (4 times). The cat is still alive without recurrence 958 days postoperatively.
