Patients with advanced hepatocellular carcinoma who have swollen feet usually need specific analysis of the problem, such as having lower limb thrombosis, lower limb vena cava thrombosis, or vena cava compression, then interventional treatment can be done, and the edema will improve after the blood vessels are usually. If it is caused by low albumin, human albumin can be supplemented. If it is caused by cardiac function, cardiac function can be improved, such as cardiotonic diuretic, and finally the edema problem can be solved. In the case of lower limb edema, try to elevate the lower limbs at home or outside, which can reduce edema.
