What are the contraindications of minimally invasive targeted interventional treatment for liver cancer? 9 contraindications of minimally invasive targeted interventional technology for liver cancer

Minimally invasive interventional targeted technology involves catheterization through the femoral artery, selective insertion into the liver cancer blood supply artery, embolization and infusion of chemotherapy drugs, embolization of the main tumor blood vessels to block the tumor blood supply, causing ischemia and necrosis of the tumor, and infusion of chemotherapy drugs to kill tumor cells.

Contraindications of minimally invasive targeted interventional techniques

1. Severe liver damage, total bilirubin> 50Umol/L, ALT> 120U, large amount of ascites or severe liver cirrhosis, liver function is Child C grade;

2. If the portal vein is completely blocked and there are few collateral vessels, embolization should be avoided as much as possible;

3. Prothrombin time is more than 2 times higher than normal. Plasma albumin is less than 25g/L;

4. Patients whose tumor occupies 70% or more of the whole liver (if the liver function is basically normal, a small amount of iodized oil can be used for embolization in several times);

5. Severe portal hypertension, severe varicose veins of the gastric fundus and esophagus, and the risk of rupture and bleeding should be treated with caution during embolization;

6. Severe hepatic artery-portal vein fistula or hepatic artery-hepatic vein fistula, if the fistula cannot be effectively blocked, embolization is not recommended;

7. White blood cell count <3×109/L;

8. Extensive metastasis has occurred throughout the body;

9. Those with general deterioration.
