Interventional treatment for hepatocellular carcinoma Percutaneous puncture hepatic artery cannulation chemotherapeutic perfusion + embolization is the most commonly used interventional treatment for the treatment of primary hepatocellular carcinoma. Even after interventional treatment for patients with middle and late stage hepatocellular carcinoma, most of them can achieve tumor control, especially, it has important clinical significance for improving patients’ quality of life and prolonging survival. Interventional treatment mechanism of liver cancer: It is a new method of directly infusing several chemotherapeutic drugs into local tumor tissues (high concentration, strong lethality and low systemic side effects) after diluting them from arterial catheters placed through percutaneous puncture, and then embolizing tumor vessels with embolic agents (ischemic starvation necrosis of tumor tissue). Advantages of interventional therapy: 1, minimally invasive 2, safety 3, good efficacy 4, less painful 5, fast recovery 6, less complications 7, repeat treatment (can intervene again for new lesions to achieve better clinical efficacy). Precautions for patients after treatment (surgery) 1, strengthen nutrition: eat more high-protein, high vitamin, high-calorie, low-fat diet, quit smoking, alcohol, spicy and other stimulating foods, eat more fruits and vegetables, keep bowel movements smooth. 2, appropriate exercise: the amount of activity does not cause palpitations, heart tiredness, shortness of breath or after the activity of the pulse does not exceed 10% of the pre-activity is appropriate, avoid overexertion. 3, regular life: maintain adequate sleep time, pay attention to climate change, avoid catching cold and flu. 4.Take medication on time: use some immune-enhancing drugs such as spleen tonics, avoid taking anti-tumor drugs, and avoid using or cautiously using drugs that damage the liver. 5.Pleasant mood: for example, listen to music, sing, play games, read newspapers, play chess and other activities. 6.Regular review: review liver CT one month after the first intervention, review liver CT in the third month after the second intervention, review liver CT once every six months after the third liver cancer intervention, generally three times of liver cancer intervention is a treatment stage, if no new tumor lesions are found in liver CT after the third intervention, there is no need for another intervention, and review liver CT once every six months thereafter. If no new tumor lesion is found after the third intervention, no further intervention is needed.
