Glue Embolization of Gastroesophageal Varices during Transjugular Intrahepatic Portosystemic Shunt (TIPS) Improves Survival Compared to Coil-only Embolization-A Single-Center Retrospective Study

Endoscopic clipping combined with cyanoacrylate injection vs. transjugular intrahepatic portosystemic shunt in the treatment of isolated gastric variceal bleeding: Randomized controlled trial

OBJECTIVES

Although the incidence of isolated gastric varices type 1 (IGV1) bleeding is low, the condition is highly dangerous and associated with high mortality, making its treatment challenging. We aimed to compare the safety and efficacy of endoscopic clipping combined with cyanoacrylate injection (EC-CYA) vs. transjugular intrahepatic portosystemic shunt (TIPS) in treating IGV1.

METHODS

In a single-center, randomized controlled trial, patients with IGV1 bleeding were randomly assigned to the EC-CYA group or TIPS group. The primary end-points were gastric variceal rebleeding rates and technical success. Secondary end-points included cumulative nonbleeding rates, mortality, and complications.

RESULTS

A total of 156 patients between January 2019 and April 2023 were selected and randomly assigned to the EC-CYA group (n = 76) and TIPS group (n = 80). The technical success rate was 100% for both groups. The rebleeding rates were 14.5% in the EC-CYA group and 8.8% in the TIPS group, showing no significant difference (P = 0.263). Kaplan-Meier analysis revealed that the cumulative nonbleeding rates at 6, 12, 24, and 36 months for the two groups lacked statistical significance (P = 0.344). Similarly, cumulative survival rates at 12, 24, and 36 months for the two groups were not statistically significant (P = 0.916). The bleeding rates from other causes were 13.2% and 6.3% for the respective groups, showing no significant difference (P = 0.144). No instances of ectopic embolism were observed in either group. The incidence of hepatic encephalopathy (HE) in the TIPS group was statistically higher than that in the EC-CYA group (P = 0.001).

CONCLUSION

Both groups are effective in controlling IGV1 bleeding. Notably, EC-CYA did not result in ectopic embolism, and the incidence of HE was lower than that observed with TIPS.

CIRSE Standards of Practice on Transjugular Intrahepatic Portosystemic Shunts

BACKGROUND

Proposed in the early 1980s as a solution for managing complications of portal hypertension, the percutaneous creation of transjugular intrahepatic portosystemic shunt has consistently gained a central role. Increasingly lower complication rates have been observed thanks to improvements in both technologies and the skills of interventional radiologists.

PURPOSE

This document is aimed at interventional radiologists and provides best practice recommendations for transjugular intrahepatic portosystemic shunt creation, describing patient selection, intraprocedural management and follow-up, in addition to recommendations in paediatric settings.

METHODS

The CIRSE Standards of Practice Committee established a writing group consisting of seven European clinicians with recognised expertise in the creation of transjugular intrahepatic portosystemic shunt. The writing group reviewed the existing literature performing a pragmatic evidence search using PubMed to select relevant publications in the English language and involving human subjects, preferably published from 2009 to 2024. The final recommendations were developed by consensus.

RESULTS

TIPS creation has an established role in the successful management of portal hypertension and its complications. This Standards of Practice document provides up-to-date recommendations for patient selection, materials, its safe performance, and follow-up with complications management.

Efficacy of TIPS plus extrahepatic collateral embolisation in real-world data: a validation study

OBJECTIVES

The efficacy of transjugular intrahepatic portosystemic shunt (TIPS) plus extrahepatic collateral embolisation (TIPS+E) in reducing rebleeding and hepatic encephalopathy (HE) post-TIPS was recently reported in a meta-analysis, but further validation is essential. This study aims to confirm the effectiveness of TIPS+E using real-world data.

METHODS

The multicentre retrospective cohort included 2077 patients with cirrhosis who underwent TIPS±E (TIPS: 631, TIPS+E: 1446) between January 2010 and December 2022. Regression and propensity score matching (PSM) were used to adjust for baseline characteristic differences. After PSM, clinical outcomes, including rebleeding, HE, survival and further decompensation (FDC), were analysed. Baseline data from all patients contributed to the construction of prognostic models.

RESULTS

After PSM, 1136 matched patients (TIPS+E: TIPS=568:568) were included. TIPS+E demonstrated a significant reduction in rebleeding (HR 0.77; 95% CI 0.59 to 0.99; p=0.04), HE (HR 0.82; 95% CI 0.68 to 0.99; p=0.04) and FDC (HR 0.85; 95% CI 0.73 to 0.99; p=0.04), comparing to TIPS. Significantly, TIPS+E also reduced rebleeding, HE and FDC in subgroup of using 8 mm diameter stents and embolising of gastric varices+spontaneous portosystemic shunts (GV+SPSS). However, there were no differences in overall or subgroup survival analysis. Additionally, the random forest models showed higher accuracy and AUROC comparing to other models. Controlling post-TIPS portal pressure gradient (pPPG) within 7 mm Hg

CONCLUSION

Our real-world data validation confirms the high efficacy of TIPS+E in reducing rebleeding and HE, particularly when using 8 mm diameter stents, embolising GV+SPSS and maintaining an optimal pPPG.

To TIPS or Not to TIPS in High Risk of Variceal Rebleeding and Acute-on-Chronic Liver Failure

Variceal bleeding is a consequence of severe portal hypertension in patients with liver cirrhosis. Although the rate of bleeding has decreased over time, variceal bleeding in the presence of acute-on-chronic liver failure (ACLF) carries a high risk of treatment failure and short-term mortality. Treatment and/or removal of precipitating events (mainly bacterial infection and alcoholic hepatitis) and decrease of portal pressure may improve outcome of patients with acute decompensation or ACLF. Transjugular intrahepatic portosystemic shunts (TIPSs), especially in the preemptive situation, have been found to efficiently control bleeding, prevent rebleeding, and reduce short-term mortality. Therefore, TIPS placement should be considered as an option in the management of ACLF patients with variceal bleeding.

Closing spontaneous portosystemic shunts in cirrhosis: Does it make sense? Does it work? What does it take?

Spontaneous portosystemic shunts (SPSS) are an often neglected cause of hepatic encephalopathy associated with cirrhosis. Nowadays, SPSS are considered as radiological biomarkers of clinically significant portal hypertension rather than the previous dogmatic perceived decompressive vessels. SPSS are not rare as they can be diagnosed in over 60% of the patients with cirrhosis by mere contrast-enhanced CT. Moreover, they are clinically relevant since they impact on all portal hypertensive related complications, in particular medically refractory HE, and represent an independent predictor of decompensation and mortality in cirrhosis, irrespective of the type of SPSS. Taken together, these elements warrant strategies to target these shunts directly which is currently is achieved via interventional radiology embolization. In this review, we discuss why it makes sense to tackle SPSS, how to do it and what it takes to do it right based on aggregated literature.

Comparison of Transjugular Intrahepatic Portosystemic Shunt in the Treatment of Cirrhosis With or Without Portal Vein Thrombosis: A Retrospective Study

Aim: The purpose of our study was to conduct a retrospective analysis to compare the effectiveness of transjugular intrahepatic portosystemic shunts (TIPS) in the treatment of patients with cirrhosis with or without portal vein thrombosis (PVT).

Methods: We included a total of 203 cirrhosis patients successfully treated with TIPS between January 2015 and January 2018, including 72 cirrhosis patients with PVT (35.5%) and 131 without PVT (64.5%). Our subjects were followed for at least 1 year after treatment with TIPS. Data were collected to estimate the mortality, shunt dysfunction, and complication rates after TIPS creation.

Results: During the mean follow-up time of 19.5 ± 12.8 months, 21 (10.3%) patients died, 15 (7.4%) developed shunt dysfunction, and 44 (21.6%) experienced overt hepatic encephalopathy (OHE). No significant differences in mortality (P = 0.134), shunt dysfunction (P = 0.214), or OHE (P = 0.632) were noted between the groups. Age, model for end-stage liver disease (MELD) score, and refractory ascites requiring TIPS were risk factors for mortality. A history of diabetes, percutaneous transhepatic variceal embolization (PTVE), 8-mm diameter stent, and platelet (PLT) increased the risk of shunt dysfunction. The prevalence of variceal bleeding and recurrent ascites was comparable between the two groups (16.7 vs. 16.7% P = 0.998 and 2.7 vs. 3.8% P = 0.678, respectively).

Conclusions: Transjugular intrahepatic portosystemic shunts are feasible in the management of cirrhosis with PVT. No significant differences in survival or shunt dysfunction were noted between the PVT and no-PVT groups. The risk of recurrent variceal bleeding, recurrent ascites, and OHE in the PVT group was generally similar to that in the no-PVT group. TIPS represents a potentially feasible treatment option in cirrhosis patients with PVT.
