Intestinal vena cava shunt

One of the other shunts is to make the superior mesenteric vein and the inferior vena cava anastomosed to reduce portal hypertension, commonly used in the intestinal cavity H-type bridge, lateral side anastomosis. H-type bridging system uses autologous jugular vein or artificial blood vessel to make the superior mesenteric vein and inferior vena cava anastomosis. Because the pressure difference between the two ends of the bridge is large, the anastomosis can be smooth and not easy to embolize, and the decompression effect is better. Can maintain part of the portal vein into the liver blood flow, the effect is satisfactory. However, hemorrhagic encephalopathy is easy to occur after operation. There are two anastomotic ports in the operation. The operation is complicated, so it is gradually replaced by lateral side anastomosis. This operation does not require bridging, simplifying operation, moderate flow rate, and less postoperative brain disease. . The anastomotic diameter is best with a diameter of 12 mm. Treatment of diseases: portal hypertension Indication Adapted to portal hypertension, variceal bleeding, splenectomy symptoms.
