Tips surgery is called transvenous intrahepatic portal-body vein stent shunt in Chinese, and the legs will still be swollen after the surgery mainly because of the obstruction of blood return. For tips surgery, the operation requires local infiltration anesthesia in the neck under interventional guidance, and then puncture the veins in the side of the neck, using catheters, guide wires and puncture needles to open up the channels between the hepatic vein and the portal vein. The surgery is quite traumatic to the body, so it is easy to cause obstruction of blood return, so that a large amount of blood is stagnated in the lower limbs, and thus swelling of the legs will occur. In addition, the surgery may also cause hepatic encephalopathy, which may seriously affect the patient’s life, so it is necessary to follow the doctor’s prescription and take medication on time to prevent it, as well as to go to the hospital for regular checkups. It is recommended to go to the hospital for a clear diagnosis and standardized treatment if the above symptoms occur.
