When hepatic artery chemoembolization is performed for hepatocellular carcinoma, it is necessary to protect liver function. The larger the area of embolization, the more serious the damage to liver function, especially when severe bile stasis hepatitis or even liver failure occurs, which may be life-threatening in serious cases. Therefore, liver function must be rechecked one week after interventional treatment. In addition, liver function of liver cancer with combined cirrhosis is poor, so liver function must be tested when interventional treatment is performed. Hepatitis B-related hepatocellular carcinoma repeatedly treated with hepatic artery chemoembolization requires adjuvant antiviral therapy, so do not wait until the rebound of virus causes liver damage before antiviral therapy, you can first choose entecavir or lamivudine combined with adefovir. Interventional embolization for large hepatocellular carcinoma is prone to secondary infection, and anti-infection treatment is required for high fever and elevated inflammatory indexes after embolization, which has been associated with life-threatening sepsis.
