DC Bead embolization with chemotherapy for liver tumors is applied to primary liver tumors and secondary liver injuries from colorectal to help preserve healthy liver parenchyma, limit hair loss compared to other types of liver cancer. with the conventional plug-in method.

1. Liver tumors and treatment of liver tumors

There are two types of liver tumors: benign liver tumors and malignant liver tumors. Malignant liver tumors are also known as primary liver cancers. The main cause of liver tumors is congenital, hepatitis B and C virus infections and bad habits such as drinking alcohol, which causes cirrhosis and 80% of the cases lead to liver cancer.
For cases of liver cancer caused by malignant liver tumors, the main treatment method is surgical removal of part of the liver with the goal of prolonging the patient's life. In case the patient's condition cannot be operated on, the doctor will consider appointing some of the following treatment methods:
Chemical embolization, including chemical embolization with DC Bead beads to treat liver tumors Using high-frequency radio waves to burn liver tumors (radiofrequency) Systemic chemotherapy.

2. Embolizes with DC Beads attached with chemicals to treat liver tumors

2.1 Advantages of chemically attached DC Beads for treatment of liver tumors. Some advantages of the method of embolization with DC Beads attached with chemicals to treat liver tumors are:
The drug concentrates at high concentrations on the tumor for a long time and is combined with necrosis to increase the effectiveness of treatment. tumor treatment. Reduces cardiovascular risk, protects healthy liver parenchyma as well as limits hair-shaking compared to conventional embolization because chemicals are only concentrated in a narrow range. Chemical embolization with DC Beads for treatment of liver tumors can be widely applied to both primary liver tumors as well as: Liver damage secondary to colorectal etiology. 2.2 When can a patient be treated for a liver tumor by embolizing with a chemically attached DC Bead 2.2.1 Cases of application Apply to patients with secondary or primary liver tumors but there is no indication for surgical intervention. skin or surgery.
2.2.2 Cases not applicable Imaging and embolization with DC Beads attached with chemotherapy for treatment of liver tumors digitized and erased background are not applied in the following cases:
Tumor has metastasized outside the liver. Invasion of the portal vein. Conducted as portal bridging (TIPS), patients with hepatic encephalopathy or patients with gastrointestinal bleeding. Contraindications related to hepatic embolization: thrombocytopenia, renal failure, infection, coagulopathy. The liver tumor is too large (larger than 50% of the liver volume). Pregnant. 2.3 The procedure of imaging and embolizing with DC Beads attached with chemicals to treat liver tumors digitally erases the background

2.3.1 Preparation The patient with liver tumor before the procedure will be explained by the doctor and medical staff for understanding and coordination. Patients need to fast for 6 hours before performing embolization with DC Bead beads attached to the treatment of liver tumors. In the procedure room, the patient is instructed to lie on his back, the devices to monitor breathing rate, blood pressure, pulse, SpO2, electrocardiogram, are installed. The procedure area is disinfected and covered with a sterile perforated towel. Local anesthesia Pre-anesthetic or anesthetic in case of need. 2.3.2 Insertion of a catheter into the artery A needle aspiration is performed and the embolization lead is inserted into the lumen of the artery (usually the right thigh), the guide wire is then brought to the aorta. The arterial puncture needle is withdrawn, then the catheter is inserted into the lumen by the guide wire. 2.3.3 Angiography The catheter is threaded into the position of the superior mesenteric artery The doctor conducts a portal vein scan to confirm that the patient with liver tumor does not have vena cava thrombosis. The visceral arteries are imaged, then a small catheter is selectively inserted into the smaller branch of the artery that feeds the liver tumors. 2.3.4 Embolization Doxorubicin solution, after being polymerized with DC Bead beads, was added with 2ml of iodinated contrast agent and pumped to the artery feeding the liver tumor.
2.3.5 After the procedure After the procedure, the patient was instructed to lie motionless in bed, at the same time immobilize the leg to conduct femoral artery puncture within 6 hours. The pulse indicators, temperature, blood pressure are monitored. 2.3.6 Periodic monitoring After taking and embolizing with DC Bead beads attached to chemotherapy for liver tumor, the patient should be monitored for 1-3 months, in case the patient's liver tumor continues to proliferate, the doctor Your doctor may consider ordering a second stopper.
