Abstract
OBJECTIVES The objective of our study was to develop a nomogram to predict post-transjugular intrahepatic portosystemic shunt (TIPS) survival in patients with cirrhosis based on CT images. METHODS This retrospective cohort study included patients who had received TIPS operation at the Wenzhou Medical University First Affiliated Hospital between November 2013 and April 2017. To predict prognosis, a nomogram and Web-based probability were developed to assess the overall survival (OS) rates at 1, 3, and 5 years based on multivariate analyses. With deep learning algorithm, the automated measurement of liver and spleen volumes can be realized. We assessed the predictive accuracy and discriminative ability of the nomogram using the concordance index (C-index), receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis (DCA). RESULTS Age, total bilirubin, and spleen volume-to-platelet ratio (SVPR) were identified as the independent risk factors for OS. The nomogram was constructed based on the above risk factors. The C-index (0.80, 0.74, 0.70), ROC curve (area under curve: 0.828, 0.761, 0.729), calibration curve, and DCA showed that nomogram good at predictive value, stability, and clinical benefit in the prediction of 1-, 3-, 5-year OS in patients with TIPS creation. CONCLUSIONS We constructed a nomogram for predicting prognosis in patients with TIPS creation based on risk factors. The nomogram can help clinicians in identifying patients with poor prognosis, eventually facilitating earlier treatment and selecting suitable patients before TIPS. ADVANCES IN KNOWLEDGE This study developed the first nomogram based on SVPR to predict the prognosis of patients treated with TIPS. The nomogram could help clinician in non-invasive decision-making.

Abstract
PURPOSE We aimed to assess the efficacy of psoas density (PD) for predicting hepatic encephalopathy (HE) after transjugular intrahepatic portosystemic shunt (TIPS) procedures. METHODS Data were collected from patients who underwent TIPS procedures at a single institution between 2013 and 2019. PD was manually measured using software on unenhanced CT scans at the level of third lumbar vertebra. Laboratory and physical examination data were collected within 24 h after admission in order to compare the differences between patients with and without post-TIPS HE. RESULTS A total of 251 patients were included in this study. Among these patients, 77 (30.7%) developed post-TIPS HE within one year after TIPS creation. The threshold of PD for predicting HE was 51.24 Hounsfield unit (HU). PD values less than this threshold were correlated with an increased risk of HE (hazard ratio 0.92; 95% CI 0.89-0.95, P < 0.001). The area under the receiver operating characteristic curve (AUROC) of PD was 0.743 (95% CI 0.685-0.796), which was superior to Model for End-stage Liver Disease (MELD) (0.569, P = 0.007), albumin-bilirubin score (ALBI) (0.641, P = 0.018), and Child-Pugh score (0.583, P = 0.003). CONCLUSION PD measurement showed good HE predictive value in cirrhotic patients who underwent TIPS. This measure also performed better than MELD, ALBI and Child-Pugh.

Abstract
Purpose We aimed to compare treatment efficacy, safety and material cost between tissue gel and coil regarding variceal embolization during transjugular intrahepatic portosystemic shunt (TIPS). Materials & Methods: This retrospective study including cirrhotic patients with variceal bleeding treated with TIPS combined with variceal embolization between January 2016 and August 2017. Patients were divided into three groups according to embolic agents used in variceal embolization: tissue gel group (Group A), combination group (Group B), and coil group (Group C). The primary endpoint was 1-year rebleeding rate after TIPS creation. The secondary endpoints included shunt dysfunction, overt hepatic encephalopathy, liver function, and embolic agents-related expense. Results A total of 60 patients (30, 10, and 20 in Group A, B, and C) were included. Variceal rebleeding occurred in 3 (10%), 0 (0%), and 4 (20%) patients within one year after TIPS creation in Group A, B, and C, respectively. Stent dysfunction occurred in 2 (3.3%) patients and 9 (15.0%) patients experienced overt hepatic encephalopathy. No significant differences were observed between three groups regarding primary and secondary endpoints except embolic agents-related expense, with a significantly lower cost in Group A when compared to the other two groups. Stent dysfunction occurred in two patients, with one patient in Group A developed acute occlusion caused by thrombus and another patient in Group C underwent stent stenosis during follow-up. Conclusions Compares to coil alone or combines with coil, tissue gel has similar treatment efficacy and safety, but with significantly lower cost for variceal bleeding during TIPS.

Abstract
RATIONALE AND OBJECTIVES Transjugular intrahepatic portosystemic shunt (TIPS) placement using the same-diameter covered stents can lead to differed declines of portal venous pressure declines (PVDs). This study aimed to compare the long-term shunt patency and clinical efficacy of TIPS placement that caused low PVDs (≤9 mmHg) and high PVDs (>9 mmHg). MATERIALS AND METHODS A total of 129 patients treated by TIPS placement with 8 mm-diameter polytetrafluoroethylene covered stents were included and analyzed retrospectively. They were stratified into group A with low PVDs (n = 69) and group B with high PVDs (n = 60). RESULTS The 6-year actuarial probabilities of remaining free of shunt dysfunction (47.2% vs 64.6%; p = 0.007) and variceal rebleeding (48.3% vs 63.9%; p = 0.038) were significantly lower in group A than in group B. The 6-year actuarial probability of remaining free of hepatic encephalopathy was significantly higher in group A than in group B (44.5% vs 32.5%; p = 0.010), though the 6-year cumulative survival rate was similar in both groups (A vs B: 65.5% vs 56.0%; p = 0.240). The baseline portal vein thrombosis (hazard ratio [HR]: 6.045, 95% confidence interval [CI]: 2.762-13.233; p = 0.000) and stent type (HR: 4.447, 95%CI: 1.711-11.559, p = 0.002) were associated with shunt dysfunction, whereas only ascites was associated with mortality (HR: 1.373, 95%CI: 1.114-3.215; p = 0.024). CONCLUSION High PVDs (>9 mmHg) were associated with higher shunt patency, lower incidence of variceal rebleeding, but higher frequency of hepatic encephalopathy and similar survival rate than low PVDs (≤9 mmHg) after TIPS placement.

Abstract
RATIONALE AND OBJECTIVES Transjugular intrahepatic portosystemic shunt (TIPS) is an established method for portal hypertension. This study was to investigate the long-term safety, technical success, and patency of TIPS, and to determine the risk factors and clinical impacts of shunt dysfunction. MATERIALS AND METHODS A total of 154 consecutive patients undergoing embolotherapy of gastric coronary vein and/or short gastric vein and TIPS creation were prospectively studied. Follow-up data included technical success, patency and revision of TIPS, and overall survival of patients. RESULTS During the study, the primary and secondary technical success rates were 98.7% and 100%, respectively. Sixty-three patients developed shunt dysfunction, 30 with shunt stenosis and 33 with shunt occlusion. The cumulative 60-month primary, primary assisted, and secondary patency rates were 19.6%, 43.0%, and 93.4%, respectively. The cumulative 60-month overall survival rates were similar between the TIPS dysfunction group and the TIPS non-dysfunction group (68.6% vs. 58.6%, P = .096). Baseline portal vein thrombosis (P < .001), use of bare stents (P = .018), and portal pressure gradient (PPG) (P = .020) were independent predictors for shunt dysfunction, hepatocellular carcinoma (P < .001), and ascites (P = .003) for overall survival. The accuracy of PPG for shunt dysfunction was statistically significant (P < .001), and a cutoff value of 8.5 had 77.8% sensitivity and 64.8% specificity. CONCLUSIONS The long-term safety, technical success, and patency of TIPS were good; baseline portal vein thrombosis, use of bare stents, and PPG were significantly associated with shunt dysfunction; shunt dysfunction has little impact on patients' long-term survival because of high secondary patency rates.

Abstract
AIM To investigate the long-term shunt patency and overall survival of transjugular intrahepatic portosystemic shunt (TIPS) placement using covered stents with or without bare stents over a follow-up period up to 7 years. MATERIALS AND METHODS A total of 154 patients undergoing TIPS placement were enrolled and analysed retrospectively. They were divided into two groups: those undergoing TIPS placement using covered with bare stents (group A, n=42) and those without bare stents (group B, n=112). RESULTS The cumulative 5-year primary patency rate was significantly lower in group A than in group B (group A: 0% versus group B: 66.7%; p<0.001). The cumulative 5-year overall survival rates were comparable between the two groups (group A: 76% versus group B: 58.7%; p=0.214). The baseline portal vein thrombosis (hazard ratio [HR]:4.610; 95% confidence interval [CI]:2.691-7.897; p=0.000), portal pressure decrement (HR: 0.911; 95% CI: 0.845-0.982; p=0.015), and group (HR: 0.419; 95% CI: 0.239-0.736; p=0.002) were independent predictors for shunt dysfunction, while hepatocellular carcinoma (HR: 6.615; 95% CI: 2.863-15.283; p=0.000) and ascites (HR: 2.166; 95% CI: 1.298-3.615; p=0.003) were independent predictors for mortality. CONCLUSIONS Although TIPS placement using covered with bare stents led to lowered long-term shunt patency than using covered stents alone, the overall survival rates were similar.

Eight millimetre covered TIPS does not compromise shunt function but reduces hepatic encephalopathy in preventing variceal rebleeding. J Hepatol 2017; 67:508-516.

Abstract
BACKGROUND & AIMS Currently, there are no recommendations in guidelines concerning the preferred diameter of stents for transjugular intrahepatic portosystemic shunt (TIPS), owing to the lack of adequate evidence. We therefore compared 8mm stents with 10mm stents, to evaluate whether 8mm stents would achieve similar shunt function, with less hepatic encephalopathy (HE) and better liver function. METHODS Cirrhotic patients were randomly assigned to receive TIPS with an 8mm or 10mm covered stent to prevent variceal rebleeding. The primary endpoint was shunt dysfunction. All-cause rebleeding, orthotopic liver transplantation (OLT)-free survival, their composite endpoint, overt HE (overall and spontaneous) and liver function were designated as the secondary endpoints. RESULTS From July 2012 to January 2014, 64 and 63 patients were allocated to the 8mm and 10mm groups, respectively. During a median follow-up of 27months in both arms, dysfunction rates (16% vs. 16% at two years, p=0.62), two-year rebleeding (16% vs. 17%, p=0.65), OLT-free survival (95% vs. 86%, p=0.37), and the composite endpoint (p=0.62) were not statistically different between the groups. Despite a marginal decrease in overall overt HE, there were significantly fewer spontaneous overt HE incidents in the 8mm group within two years (27% vs. 43%, p=0.03), with a risk reduction of 47%. Notably, patients receiving 8mm stents also developed less hepatic impairment. CONCLUSIONS TIPS with 8mm covered stents showed similar shunt function to TIPS with 10mm stents, but halved the risk of spontaneous overt HE and reduced hepatic impairment. Therefore, 8mm TIPS stents should be preferred for the prevention of variceal rebleeding in cirrhotic patients. Lay summary: The optimal diameter for transjugular intrahepatic portosystemic shunt (TIPS) remained uncertain. This study showed that TIPS with 8mm covered stents did not compromise shunt patency, or influence the efficacy of variceal rebleeding prevention compared to TIPS with 10mm stents, but reduced the risk of spontaneous overt hepatic encephalopathy and the incidence of severe encephalopathy. Moreover, liver function reserve was also better in the 8mm stents group, suggesting that 8mm TIPS stents should be preferred for the prevention of variceal rebleeding in cirrhotic patients.
