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.

1. What is a digital background eraser and portal vein node?

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.

2. Indications and contraindications for digital background erasure and portal venous nodes

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.

3. Steps to take digital scan to remove background and node of portal venous system

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.

4. Complications and how to handle after implementing the method

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).
