Abstract Background The prognosis of hepatocellular carcinoma (HCC) with vascular invasion is extremely poor, especially in patients with tumor thrombus (TT) of the inferior vena cava (IVC), which is an oncological emergency with a high risk of sudden death due to TT extension or migration. Herein, we describe a case of HCC with TT of the IVC that rapidly extended into the right atrium (RA), in which right hepatectomy was performed under cardiopulmonary bypass. Case presentation A 64-year-old man was diagnosed with HCC with IVC TT, and right hepatic lobectomy was scheduled. While awaiting surgery, he complained of respiratory distress and rushed to the emergency room. The TT had reached the RA, and the patient was in a state of oncologic emergency. We requested the cooperation of the cardiovascular surgery department, and under artificial cardiopulmonary support, the right atrium was incised, and a part of the TT was removed. The IVC was clamped to prevent tumor dispersal, and right hepatic lobectomy was performed. The remaining thrombus was excised along with the right lobe of the liver by incising the IVC. There were no serious postoperative complications, and the patient is alive 1 year and 5 months postoperatively. Conclusion Hepatic resection with cardiopulmonary bypass could be an option for HCC with TT reaching the RA.
