Analysis of the medium-term curative effect of transjugular intrahepatic portosystemic shunt through jugular vein with covered Viatorr stent

Abstract

Objective: To investigate the medium-term curative effect of transjugular intrahepatic portosystemic shunt (TIPS) through jugular vein with covered Viatorr stent. Methods: Data of 105 consecutive patients with covered Viatorr stent of our hospital was retrospectively analyzed. Follow-up was performed after surgery, and color Doppler was reviewed to evaluate the efficacy of TIPS. Results: Transjugular intrahepatic shunt was successfully established in all patients. The pressure gradients of portal vein before and after operation were 22.33 ± 6.4 mmHg and 9.78 ± 4.9 mmHg, respectively,P< 0.01, and the difference was statistically significant. The follow-up period ranged from 12.7 to 15.6 months, with an average of 13.09 ± 1.4 month. Total bilirubin and coagulation time increased after operation, but there was no significant difference in total bilirubin and coagulation time at 1, 3, 6 and 12 months after operation. The patency rate of shunt was 100%, 99.05%, 99.05% and 99.05% at 1, 3, 6 and 12 months after operation. The incidence of hepatic encephalopathy was 34.2%, 29.5%, 19.1% and 14.3% respectively. The recurrence rate of symptoms was 0%. Conclusion: Patients with cirrhotic portal hypertension who underwent TIPS with covered Viatorr stent had a lower rate of restenosis, improved liver function, and a lower incidence of severe hepatic encephalopathy. However, the long-term efficacy needs further observation.
