What is the role of peritoneal venous shunt?

The abdominal main vein is the inferior vena cava, and there are two branches directly injected into the inferior vena cava: mural branch and visceral branch. The unpaired visceral branches first flow into the hepatic portal vein and then return to the inferior vena cava through the hepatic vein. So what is the effect of peritoneal venous shunt? Let's have a look.

1. What is the role of peritoneal venous shunt?

Abdominal shunt is a surgical method for the treatment of portal hypertension due to liver cirrhosis. Its main purpose is to reduce the portal vein pressure, thus reducing the possibility of upper gastrointestinal bleeding. If the operation is successful, there will be no excessive abnormal drainage after the operation, and the patient can resume eating quickly after the operation because there is no excessive interference to the gastrointestinal tract. But for the choice of diet, we should pay attention to choosing soft food, because varicose veins can't disappear completely in a short time, and once there is a big rupture and bleeding, it will still endanger the life of patients.

Second, how to care for ventriculoperitoneal shunt?

Nursing care after ventriculoperitoneal shunt is very important. Generally speaking, wounds should be kept clean and dry to avoid infection. At the same time, always press the pressure valve of the shunt pipe to keep it unobstructed and prevent the pipeline from blocking. Ventricular shunt is not difficult, but complications, including infection and catheter blockage, are easy to occur after operation. The purpose of ventriculoperitoneal shunt is to drain excess water from the brain into the stomach. As long as the drainage tube is unobstructed, the purpose of drainage can be achieved by adjusting the pressure. The adjustment pressure can also be adjusted repeatedly, provided that the drainage tube is unobstructed. Therefore, it is very important to keep the drainage tube unobstructed after ventriculoperitoneal shunt, and it is absolutely necessary to prevent retrograde infection.

2. In addition, pay attention to supine position after operation. The head can be tilted to one side, but it must not be lifted to prevent the intracranial pressure from changing. At the same time, we must prevent the head from violent movement and overstretching. Note the color of cerebrospinal fluid after drainage. Normal cerebrospinal fluid should be white and clear. If there is abnormal color, it means that the brain is infected, and anti-infective drugs should be used as soon as possible for treatment.
