Hepatic artery chemoembolization (TACE) is the first choice of non-surgical treatment for hepatocellular carcinoma, and also the main method of postoperative consolidation treatment for hepatocellular carcinoma. Through super-selecting the blood vessels supplying the tumor, injecting chemotherapeutic drugs and embolic agents, the tumor is necrosed and reduced in size by blocking the blood supply to the tumor and controlling the fluid growth. For patients who cannot be removed surgically, intervention can be done once in 6-8 weeks according to the imaging and AFP situation until satisfactory results are achieved. Common symptoms after intervention: 1, blood leakage from the puncture site, attention should be paid to the puncture site pressure for 12 hours, and absolute bed rest for 24 hours, and the puncture side of the limb to avoid bending pressure, in order to prevent the puncture port bandage loosening or moving, and cause the puncture site bleeding, edema and other conditions 2, nausea and vomiting, loss of appetite is the toxic side effects of chemotherapy drugs, can be given with acid suppressant drug therapy, at the same time, adjust the patient’s mood, available to distract The incidence and severity of vomiting can be reduced by distracting, chatting and adjusting the environment to control patients’ emotions. 3, epigastric pain After TACE treatment, the liver cells in the chemotherapeutic drugs and local ischemia caused by the transient edema caused by the liver was felt tension, contrast agent, embolic agent direct stimulation, etc. caused by abdominal pain, pain confined to the liver area, with distension, slight burning sensation, can be relieved within 1 week. The patient is advised to rest in bed for 24h, avoid excessive activities, closely observe the site and nature of abdominal pain to exclude the possibility of complications of cholecystitis and pancreatitis, and give analgesic treatment, such as aminophenol dihydrocodeine, if necessary. 4, postoperative fever is one of the common complications of interventional therapy, which is caused by coagulative necrosis of tumor, resulting in absorption of heat, generally 37.5 degrees -38.8 degrees fluctuations, more than 38 degrees Celsius can be given cooling treatment, patients need to pay attention to drink more water to promote the excretion of toxic substances, at the same time, patients with poor resistance, coupled with fever and sweating, very easy to catch a cold, need to be cautious, can not be measured by normal people. 5, upper gastrointestinal bleeding, patients manifest as vomiting blood, mostly due to stress ulcer causing gastrointestinal bleeding, but it can also be caused by portal hypertension caused by iodized oil flowing backwards into portal vein and obstructing portal blood flow (extremely rare), but patients with liver cancer are mostly accompanied by portal hypertension, esophagogastric fundic varices, improper diet is the main cause of upper gastrointestinal bleeding. Patients should not eat hard, spicy and hot food, and chew slowly. 6, ascites. The patient’s postoperative liver function damage, coupled with gastrointestinal reactions, the patient’s diet is poor, the patient’s hypoproteinemia, resulting in ascites, while portal hypertension is also a very important reason for the formation of ascites, in addition to cancerous ascites can not be ruled out (late stage is common). Can be given with a high protein diet, while home diuretic drugs. 7.Infection. After tumor necrosis, the body’s body resistance is poor and cannot be absorbed, combined with bacterial infection, the formation of liver abscess, manifested as persistent high fever, more than 39 ℃, cut the patient’s general condition is poor, the symptoms of infectious shock, treatment: timely consultation, strengthen anti-sensitivity treatment, while performing liver abscess puncture and drainage. (Rare) First of all, avoid, take some drugs that are harmful to the liver. Now some patients will seek medical help after they get sick, this psychology is understandable, but the drugs they seek are often actually unclear about some of the ingredients, which are very damaging to liver function, and in the process of indiscriminate treatment, causing further damage to liver function, preventing you from doing further interventions. As the digestive function of liver cancer patients is poor, these patients should eat less and more meals and avoid greasy food, so that they do not feel poor digestion and always have indigestion. As for some proteins including animal proteins, such as fish and shrimps, they are not related to each other, but we must eat less meals and avoid greasy food. Interventional complications and precautions for hepatocellular carcinoma have been introduced in detail. Interventional treatment is generally a safer treatment option, I hope you can rest assured, and don’t worry too much about common complications. In addition to drug treatment, tumor patients are largely determined by patients’ mentality. We hope that patients can actively cooperate with treatment and keep a good mentality at the same time, and we will meet the requirements of patients and their families to the greatest extent.
