Abstract
BACKGROUND: Treatments for hepatic sinusoidal obstruction syndrome (HSOS) are limited. AIM: To evaluate transjugular intrahepatic portosystemic shunting (TIPS) as a treatment for pyrrolidine alkaloid-related HSOS (PA-HSOS). METHODS: This retrospective analysis included patients with PA-HSOS admitted to the First Affiliated Hospital of the University of Science and Technology of China (June 2015 to January 2019). Baseline clinical characteristics and follow-up data were extracted from the medical records. All patients included in this study experienced failure of initial therapy. Patients were divided into the TIPS and conservative treatment groups according to the therapy they received. Liver function, maximal ascites depth, imaging characteristics, pathology findings, and survival were compared between groups. RESULTS: < 0.05) but not in the conservative treatment group. Contrast-enhanced computed tomography demonstrated the disappearance of patchy liver enhancement after TIPS. Pathology showed that liver congestion and hepatocyte swelling improved with time after TIPS placement. CONCLUSION: TIPS may achieve better outcomes than conventional symptomatic treatment in patients with PA-HSOS.
