The Follows Of The Covered Stents Implanted By Transjugular Intrahepatic Portosystemic Shunt To Portal Hypertension

Objective:To expore the changes on the extents of portal hypertension before and after transjugular intrahepatic portosystemic shunt(TIPS),and to investigate the improves of the signs and symptoms, and the next complications.Material and Method:A total of 32 patients with portal hypertension from Departments of Gastroenterology Provincial Hospital and Qianfoshan Hospital affiliated to Shandong University were executed TIPS with Covered Stents. Result:In all of the 32 patients except two cases failure of severe portal vein thrombosis, the remaining 30 cases were successfully completed the operation, and the postoperative portal pressure was significantly reduced (the reducation rate> 30%).There was a significant statistical significance. The clinical signs and symptoms were greatly improved.During in the 1-3 years of follow-ups, the 1,2,3 years rebleeding rates are 9.09% 3.33%,20% respectively;stent stenosis rates 1,2,3 years,6.66%,13.63%, 30% respectively, hepatic encephalopathy (or called portal encephalopathy, PSE) in 1, 2,3years,60.0%,90.90%,100.0% respectively, but the PSEII rates occur in 1,2,3years are 3.33%,4.55% 10.0% respectively.Conclusion:the diameter of 8mm covered stents can effectively relieve the portal hypertensionof hepative cirrhosis, and can effectively prevent patients from rebleeding of esophageal gastric varices or refractory ascites.Though the hepatic encephalopathy frequently occured, but most of which were PSEI, so TIPS, conbining with other methods must be the more effective method to the treatment of portal hypertension of liver cirrhosis.
