Patients with heart failure usually cannot undergo liver cancer interventional surgery; if the heart failure is corrected, surgery can be performed as appropriate. Liver cancer interventional surgery refers to the embolization of blood vessels supplying blood to the tumor in order to cut off the source of blood, and at the same time, chemotherapy drugs are given as a way to inhibit the growth of the tumor. Patients with very serious heart failure have unstable vital signs and are at risk of surgery, so they cannot undergo liver cancer interventional surgery, but if the heart failure can be corrected after treatment, they can undergo surgery depending on the situation. Before undergoing liver cancer interventional surgery, patients can have electrocardiogram, chest X-ray and heart ultrasound, etc. to determine the heart function, which will be the basis of whether the surgery can be performed or not. Liver cancer patients should be treated according to medical advice to avoid serious consequences.
