Digital erasure of the background and node of the portal vein system is a method of treatment for primary liver cancer when the patient has an indication for major hepatectomy but the remaining liver volume is not enough and there is no liver failure.

Digital erasure of the background and portal vein node is a method of treating primary liver cancer when patients with liver cancer are indicated for major hepatectomy but the remaining liver volume is not enough and there is no liver failure.
This method completely treats the tumor, but about 80% of cases when it is found that it is no longer possible to operate due to many reasons, one of the reasons that cannot be operated is the remaining liver volume after surgery. insufficient. The planned portal vein node surgery causes enlargement of the remaining liver, increasing the possibility of surgical treatment for the patient.

Indications for digital scan to erase background and node of portal vein system when:
Patients with liver cancer are indicated for major liver resection but the remaining liver volume is not enough. No liver failure. Digital imaging is contraindicated to remove the background and nodes of the portal venous system when:
Liver tumor has extensive spread in the liver (lesions in subdivisions I, II, III) Left liver tumor (injury to subsegments VI and VII) Liver tumor with vascular invasion Liver tumor with biliary dilatation, portal hypertension. Patients with heart failure, severe kidney failure Have lymph node metastasis, lung metastasis Coagulation disorders, platelets Pregnant women.

Step 1: Preparation: Digital background eraser, dedicated electric pump, ultrasound machine with curved transducer, sterile nylon bag wrapped with ultrasound probe, image storage system, X-ray shielding; local anesthetics, pre-anesthetics and general anesthetics, anticoagulants, anticoagulants neutralizers, water-soluble iodine contrast agents, skin and mucosal antiseptic solutions. Medical supplies. Materials that cause embolism. Step 2: Ask the patient to fast for 6 hours before the procedure. Step 3: Ultrasound selects the portal vein entry and the portal vein puncture site, then numbs the entry from the subcutaneous layer to the liver capsule and inserts the needle into the vein branch. Step 4: Insert the 0.035” lead into the portal vein body, then place the 5F to 8F catheterizer and take an anatomical examination of the portal vein system through the 5F catheter, the dose of iodinated contrast agent 15ml, pump speed 5ml/s. Step 5: Plug the portal vein branches with embolization material. Step 6: Take a check after occlusion of portal vein branches, then remove the vascular opener, plug the puncture with embolization material.

Intra-abdominal bleeding: Check the bleeding site and perform embolization to stop the bleeding. Wrong displacement of the stopper material: Reposition. After the procedure, there may be subcapsular hematoma, abdominal pain (treated with common analgesics). The danger of liver cancer has shown the importance of screening and early detection of the disease. Therefore, Vinmec International General Hospital has provided customers with a package of screening and early detection of liver cancer to screen for liver cancer pathology for people at high risk of disease such as: alcoholics, cirrhosis, family history of liver cancer, cirrhosis, hepatitis B virus infection, chronic hepatitis C,...
Service selection Package for screening and early detection of liver cancer, patients will be examined, consulted and performed tests, diagnostic imaging to evaluate liver function, liver diseases and liver cancer screening. With a system of modern machinery and a team of highly qualified and experienced doctors, Vinmec is committed to the best protection for the health of patients.
