hepatocellular carcinoma (HCC) combined with inferior vena cava and right atrial thrombus can lead to serious complications such as acute pulmonary infarction and heart failure. The median survival time for untreated patients is less than 6 months.[1,2]。 For primary resectable HCC, surgery remains an important means to relieve obstruction and prevent sudden death.[3,4]。 At present, the classic surgical method for the treatment of right atrial cancer thrombus is to incision the right atrium under cardiopulmonary bypass to remove the thrombus, but it is traumatic and complicated to operate. In clinical practice, we have explored a technique to remove the right atrial cancer thrombus by pushing and pushing through extrapericardial fingers without opening the atrium, which is reported below.
