The uncompensated stage of cirrhosis of Bu-Ga’s syndrome can lead to abdominal fluid, edema, thrombus, etc. The treatment includes thrombolysis, puncture and aspiration, antibiotic and antimicrobial therapy. 1. Cirrhosis decompensation caused by Buerger’s syndrome is mainly due to the blockage of hepatic vein and inferior vena cava, so that the blood can not return to the heart to cause ascites, swelling of the lower limbs, etc. Cirrhosis of the liver for a long time leads to portal hypertension and thrombosis. Therefore, thrombolysis or anticoagulation is needed. 2. If there is too much fluid in the abdominal cavity, puncture and fluid extraction with infusion of clear protein, combined use of spironolactone and furosemide for diuresis, and transjugular intrahepatic portacaval shunt can be carried out. If the peritoneal effusion is complicated by spontaneous bacterial peritonitis, cefoperazone and other drugs can be used for treatment. It is recommended to go to the hospital for timely treatment, use medication as prescribed by the doctor, and undergo surgery if necessary.
