Inferior vena cava stenosis balloon dilatation stenting for Budd-Chiari syndrome (BCS) is a posthepatic portal hypertension caused by obstructive lesions of the hepatic vein and/or the inferior vena cava above its opening, often accompanied by inferior vena cava syndrome, and is also known as hepatic vein-ventricular vein syndrome. Since Buga syndrome is mainly caused by the high degree of narrowing or occlusion of the inferior vena cava and hepatic vein of the hepatic segment of the patient, it can lead to hepatic stagnation, cirrhosis, ascites, and poor venous return to the lower limbs, edema of the lower limbs, and skin ulcers. The patient’s symptoms and signs are similar to those of cirrhosis, making it highly susceptible to misdiagnosis. The main difference between Buerger’s syndrome and cirrhosis is the narrowing or occlusion of the hepatic outflow tract in the former; and the hepatic lesions in the latter. The former mostly have no special medical history, the latter in our country to hepatitis disease, cirrhosis, toxic cirrhosis, followed by schistosomiasis liver fibrosis, alcoholic cirrhosis is also increasing year by year. Chifeng City Hospital Vascular Surgery Department Dang Yongkang Recently our hospital vascular surgery department admitted a typical patient with Buga syndrome, the patient is male, 29 years old, was diagnosed with Buga syndrome in 2008 and underwent inferior vena cava balloon dilatation in 301 hospital. On January 29, 2011, the patient came to our hospital for treatment of right calf vein rupture and bleeding, and the CT review showed severe stenosis of the inferior vena cava in our hospital. The patient underwent inferior vena cava balloon dilatation stenting, and the intraoperative imaging showed that the patient’s inferior vena cava was patent, and the stent position was in good shape. The patient recovered well after the operation and was discharged from the hospital. Membranous obstruction of the inferior vena cava is a common type in patients with Buerger’s syndrome in China. According to the recent statistics of the Affiliated Hospital of Xuzhou Medical College, the incidence of this type of obstruction is 46%, and the diaphragm is located in the inferior vena cava above the opening of the hepatic vein. Domestic and foreign literature have recognized that membranous obstruction of the inferior vena cava is the best indication for interventional therapy. As the number of patients with Bu-Ga syndrome in China is the highest in the world, in recent years, many medical units in China have carried out technical research on the interventional treatment of Bu-Ga syndrome, which has made the success rate of interventional treatment of Bu-Ga syndrome reach 95%, and its technical level has reached the international advanced level.
