hepatic artery ligation

Hepatic artery ligation is a procedure in which liver arteries are ligated to block the arteries of the disease, block blood flow and nutrient supply, and prevent bleeding. Treatment of diseases: cirrhosis, ascites, biliary tract bleeding Indication 1. When biliary bleeding cannot be removed. 2. In the late stage of portal hypertension, the ascites can not be treated by internal medicine. The general condition of the patient is poor, and the patient cannot undergo large surgery, but the curative effect is not clear enough. Preoperative preparation Antibiotics are routinely used before surgery. Surgical procedure 1. Position: supine position. 2. Incision: right upper transabdominal rectus incision. 3. Exploration: After entering the abdominal cavity, carefully explore the liver, gallbladder, duodenum, stomach, spleen and so on. Then, use the left hand to extend into the retina hole, and touch the common bile duct and hepatic artery with the index finger and thumb. 4. Reveal the proper hepatic artery: The normal hepatic artery is located on the left side of the common bile duct. The liver and duodenum were retracted with a hook, and the hepatoduoduus ligament was longitudinally cut along the common bile duct to find the proper hepatic artery. Carefully bluntly separate the proper hepatic artery from the left side of the common bile duct. Be careful not to damage the common bile duct and portal vein. 5. Ligation of the proper hepatic artery: Two medium-sized silk threads were introduced from the posterior aspect of the hepatic artery, and the hepatic artery was double-ligated. The hepatoduodenal ligament was sutured intermittently with a thin wire. 6. Separate the layers of the abdominal wall layer by layer.
