CIRSE Standards of Practice on Transjugular Intrahepatic Portosystemic Shunts.

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. 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. 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. 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.

Post-TIPS Right Atrial Pressure and Left Atrial Volume Index Predict Heart Failure and Mortality: Dual Center Experience

Background: Heart failure (HF) after Transjugular Intrahepatic Portosystemic Shunt (TIPS) placement affects up to 20% of patients. Understanding factors associated with post-TIPS HF is critical. Cirrhotic Cardiomyopathy (CCM) is associated with adverse clinical outcomes. Aims: We aim to evaluate whether hemodynamic measurements and echocardiographic markers of CCM pre- and post-TIPS can predict post-TIPS HF and death. Methods: We performed a retrospective study of cirrhotic patients who underwent TIPS between 2010 and 2015 at two centers. Patients with cardiomyopathies other than CCM were excluded. A multivariable-adjusted time-to-event analysis assessed associations of clinical, hemodynamic, and echocardiographic parameters with post-TIPS HF and death during 2 years of follow-up. 180-day landmark analysis was used to assess association of echocardiographic changes with outcomes. Results: 360 patients met study criteria. 32 developed HF post-TIPS (8.8%). Right atrial pressure (RAP) measured intraprocedurally post-TIPS insertion was associated with increased risk for HF (adjusted HR 1.10 [1.04-1.17]), with a cut off of 22mm Hg associated with highest risk (multivariable HR 2.71, [1.22-6.02]. 92 patients died (25.5%). An increase in left atrial volume index (LAVI) within 180 days post-TIPS was associated with increased mortality (HR 1.08 [1.01-1.15]). Other echocardiographic CCM markers were not associated with HF or death. Conclusion: Increases in RAP and LAVI post-TIPS, but not CCM status, predict post-TIPS HF and death, respectively. Surveillance echocardiography may play a role in identifying those at highest risk of decompensation post-TIPS. Further prospective study of CCM and its markers in relation to TIPS outcomes is warranted.

TIPS, a Trick for Transcaval TEVAR Access.

We described an alternative access for thoracic endovascular aortic repair (TEVAR) deployment using a transjugular intrahepatic portosystemic shunt (TIPS) needle for gaining transcaval access to the abdominal aorta. A 63-year-old man presented with a penetrating atherosclerotic ulcer in the descending aorta. Traditional transfemoral and transaxillary access were not possible. A transcaval access was established using a TIPS needle to puncture from the caval vein to the aorta. Next, the access was gradually upsized until a 22 french large-bore transcaval access was achieved. Afterwards the thoracic endograft was positioned and deployed accustomed. The infrarenal aortocaval fistula was closed with a covered stent. When classic TEVAR access is not possible, transcaval access is a valuable and minimally invasive alternative access. We prefer the use of a TIPS needle for gaining access and use a covered stent for closing the aortic access site when possible instead of using electrified wires nor a transseptal occluder device. Preoperative planning remains key. We discribe a transcaval access with a TIPS needle and closing of the aortocaval fistula with a covered stent. We are one of fiew reports of transcaval puncturing instead of using an electrified wire and the first using a TIPS needle for gaining transcaval access. We hope this case and our comments help other surgeons, radiologists and patients when they are in need of a transcaval access and contribute to a successful procedure.

Psoas muscle index in sarcopenia following transjugular intrahepatic portosystemic shunt: A multicenter, retrospective study

AbstractAimsAlthough the skeletal muscle index at the third lumbar vertebra (L3‐SMI) is commonly utilized for the diagnosis of sarcopenia, the psoas muscle index at L3 (L3‐PMI) may serve as a reliable alternative indicator. This study aims to investigate the application of the PMI in patients who have undergone transjugular intrahepatic portosystemic shunt (TIPS).MethodsThis study included a cohort of 406 patients with cirrhosis who underwent TIPS between February 2016 and July 2022 across three medical centers in China. Clinical and imaging data, specifically L3‐SMI and L3‐PMI, were collected for these patients. The prognosis of the patients was assessed through re‐examinations and telephone follow‐ups, which extended up to 5 years. The diagnostic thresholds for sarcopenia, as defined by L3‐PMI and L3‐SMI, were established at 6.36 or 42.00 cm²/m² for males and 3.92 or 38.00 cm²/m² for females, respectively. Cox proportional hazards and Kaplan–Meier (K‐M) analyses were employed to evaluate patient survival.ResultsThe findings indicated that both L3‐PMI and L3‐SMI before TIPS were independent risk factors for mortality. The results of the paired t‐test demonstrated a significant increase in L3‐PMI 1 month post‐TIPS (5.11 ± 1.81 vs. 5.71 ± 1.90 cm²/m², p < 0.001), whereas L3‐SMI did not exhibit a significant increase until 6 months post‐TIPS (45.45 ± 9.41 vs. 48.59 ± 10.38 cm²/m², p < 0.001). Among these patients, 191 (47.0%) and 159 (39.2%) were diagnosed with sarcopenia according to the L3‐PMI and L3‐SMI models, respectively. Patients identified as sarcopenic by both indicators demonstrated a significantly lower survival rate (L3‐SMI model: hazard ratio [HR], 1.913; 95% confidence interval [CI], 1.094–3.410; log‐rank p = 0.020; L3‐PMI model: HR, 1.867; 95% CI, 1.059–3.290; log‐rank p = 0.030). In sarcopenic patients, the reversal of sarcopenia associated with improved survival occurred 1 month after TIPS in the L3‐PMI model (HR, 2.675; 95% CI, 1.245–5.735; log‐rank p = 0.012), while a similar effect was not observed until 6 months post‐TIPS in the L3‐SMI model (HR, 3.342; 95% CI, 1.477–7.560; log‐rank p = 0.004).ConclusionsL3‐PMI and L3‐SMI demonstrate comparable efficacy in diagnosing cirrhosis‐related sarcopenia. Furthermore, L3‐PMI has the capacity to identify improvements in sarcopenia as early as 1 month following TIPS, thereby providing earlier insights into patient survival outcomes.

Recompensation of Liver Cirrhosis by TIPS Reduces Epithelial Cell Death Markers, Translating Into Improved Clinical Outcome.

Portal hypertension is the main pathophysiological driver of decompensation in patients with liver cirrhosis. Epithelial cell death markers, m30 and m65, correlate with hepatic injury and predict outcomes across various stages of liver disease. We aim (i) to evaluate whether portal hypertension itself contributes to liver outcome-relevant epithelial injury, and (ii) to analyse the capacity of m30/m65 to predict outcome in patients receiving a transjugular intrahepatic portosystemic shunt (TIPS) for refractory ascites. Sixty-six patients undergoing TIPS placement for refractory ascites and 20 patients with compensated cirrhosis as controls were prospectively enrolled in this monocentric cohort study. Epithelial cell death markers were analysed pre-TIPS, as well as 1-3 and 6-9 months post-TIPS. The capacity of baseline levels of m30/m65 in predicting six-month transplant-free survival rates was analysed by multivariable Cox proportional hazards regression. Levels of m30 and m65 were higher in patients with decompensated cirrhosis (pre-TIPS) compared with compensated cirrhosis (controls). Following correction of portal hypertension by TIPS and recompensation, both markers decreased over time, reaching levels comparable to patients with compensated cirrhosis. On multivariable analysis, pre-TIPS baseline levels of m30 and m65 were not predictive for six-month survival. Correction of portal hypertension via TIPS reduces levels of epithelial cell death markers, indicating that portal hypertension is a driver of outcome-relevant, hepatic cell death in patients with decompensated cirrhosis. Baseline m30/m65 values do not affect six-month survival rates, which suggests that TIPS placement overcomes the unfavourable spontaneous prognosis otherwise indicated by elevated baseline m30/65 levels.

Optimal threshold of portal pressure gradient for patients with ascites after covered TIPS: a multicentre cohort study.

Transjugular intrahepatic portosystemic shunt (TIPS) is recommended for treating recurrent and refractory ascites. However, determining the target portal pressure gradient (PPG) has been inconclusive. This multicentre cohort study explored the post-TIPS PPG potential range associated with improving survival. The study enrolled 276 patients, all of whom underwent covered TIPS for ascites treatment across four medical centers. The cumulative incidences of clinical outcomes were compared among groups categorized by potential PPG thresholds. During the whole follow-up period with a medium follow-up of 21.6 (7.5, 41.6) months, 122 (44.2%) experienced liver-related death, and 73 (26.4%) patients experienced a recurrence of ascites. Multivariable analysis revealed PPG < 7mmHg (p = 0.007) and the recurrence of ascites (p = 0.033) are independent risk factors for survival, while the PPG ≥ 11mmHg was an independent risk factor for the recurrence of ascites (p = 0.012). Patients with ≥ 7mmHg had a lower rate of liver-related death than patients with post-TIPS PPG < 7mmHg (51.0% vs 66.6%, p = 0.004), while those with post-TIPS PPG ≥ 11mmHg exhibited a higher cumulative incidence of ascites compared to those with post-TIPS PPG < 11mmHg (44.6% vs 33.7%, p = 0.023). The robustness of the results was confirmed. Our study highlighted the existence of an optimal post-TIPS PPG range in patients with recurrent and refractory ascites. Patients may experience improved survival and ascites control with a post-TIPS PPG of 7-11mmHg.

Portal Hypertensive Gastropathy and MELD-Na Score Predict Recurrent Gastrointestinal Bleeding After TIPSS: An ALTA Group Study.

Transjugular intrahepatic portosystemic shunt (TIPSS) is highly effective for treatment of variceal bleeding; however, factors contributing to rebleeding complications remain unclear. In this study, we aim to determine risk factors for recurrent portal hypertensive gastrointestinal bleeding following TIPSS. Utilising the Advancing Liver Therapeutic Approaches multicentre database, we retrospectively identified adult patients who underwent TIPSS for secondary prophylaxis of variceal bleeding and had a gastrointestinal rebleeding event within 1 year. We developed multivariable logistic regression models to identify clinical/procedural characteristics associated with rebleeding. We identified 476 patients, predominately middle-aged (mean age 57), male (62%) and White (65%), with mean MELD-Na 16. 16% (n = 77) had a rebleeding event; these patients were more likely to be male (p = 0.016), with higher serum creatinine (p = 0.005), MELD-Na (p = 0.0002), portal hypertensive gastropathy on pre-TIPSS upper endoscopy (p = 0.000) and with higher incidence of TIPSS revision (p = 0.000). There were no significant differences in type of TIPSS endoprosthesis, concurrent embolotherapy, and post-TIPSS pressure gradients between those who experienced rebleeding and those who did not. After adjusting for TIPSS revision, multivariable analysis revealed MELD-Na and presence of portal hypertensive gastropathy on pre-TIPSS endoscopy were independently associated with rebleeding. In this retrospective analysis of a multicentre, nationally representative database, we found that apart from TIPSS-related factors, high MELD-Na and portal hypertensive gastropathy on pre-TIPSS endoscopy were independent predictors of rebleeding within 1 year following TIPSS. These variables may be used to identify high-risk patients who may require additional monitoring following TIPSS.

Clinical Outcomes of Transjugular Intrahepatic Portosystemic Shunt Among Cirrhosis Patients With Recurrent Esophageal Variceal Bleeding

Clinical Outcomes of Transjugular Intrahepatic Portosystemic Shunt Among Cirrhosis Patients With Recurrent Esophageal Variceal Bleeding

Percutaneous thermal ablation in hepatocellular carcinoma patients with and without TIPS.

Managing hepatocellular carcinoma (HCC) in patients with a transjugular intrahepatic portosystemic shunt (TIPS) is becoming increasingly common. This study aimed to evaluate the safety and efficacy of percutaneous thermal ablation for treating HCC in patients with TIPS. This retrospective longitudinal study was conducted at Nantes University Hospital. The main inclusion criteria were patients undergoing percutaneous thermal ablation for HCC. Patients with a pre-existing TIPS were included in the 'TIPS group'. A 1:1 control group without TIPS, the 'n-TIPS group', was created for this case-control study. The primary endpoints were overall survival and progression-free survival over 12 months. Safety was assessed by comparing complications between the groups. Between 2008 and 2020, 371 patients underwent percutaneous thermal ablation for HCC. The 'TIPS group' included 34 patients (66 nodules), while 34 patients (84 nodules) were randomly assigned to the 'n-TIPS group.' Overall survival rates at 1 year were 97% and 94% respectively (p = 0.52). The progression-free survival rate was 68% and 57% respectively (p = 0.35). No deaths occurred within 30 days post-procedure. There were 3 immediate complications in the TIPS group and 4 in the n-TIPS group (p = 1), none of which were related to the TIPS, including thrombosis. Percutaneous thermal ablation for HCC in patients with TIPS appears to be as safe and effective as in TIPS-naïve patients. These results suggest that the presence of a TIPS should not be considered a contraindication for percutaneous thermal ablation in treating HCC.

Evidence for preventing EVRB in cirrhotic patients: A systematic review.

Systematic strategies for preventing and treating esophagogastric variceal rebleeding (EVRB) are currently inadequate. This systematic review aimed to update this critical gap by searching contemporary studies from major guideline websites, databases, and professional associations focused on EVRB prevention in cirrhosis patients. Key findings highlight evaluation methods, risk management, preventive measures, health education, and follow-up strategies. Notably, a hepatic venous pressure gradient exceeding 18 mmHg is identified as a reliable predictor of gastroesophageal varices (GOV) rebleeding. Effective management of primary diseases is crucial, with methods including antiviral and anti-fibrotic therapies, alcohol avoidance, vaccination, and careful medication management. The combination of nonselective β-blockers (NSBBs) and endoscopic variceal ligation (EVL) is established as the gold standard for secondary EVRB prevention. For patients experiencing recurrent bleeding despite NSBBs and EVL, transjugular intrahepatic portosystemic shunt (TIPS) therapy is recommended. Surgical options, such as surgical shunt and devascularization, are advised for those unsuitable for endoscopic therapy or TIPS, particularly in Child-Pugh A and B patients unresponsive to treatment. Additionally, traditional Chinese medicine options, such as Fufang Biejia Ruangan Tablets, Fuzheng Huayu Capsules, and Anluo Huaxian Pills, have shown promise in improving hepatic fibrosis and GOV in cirrhotic patients. This review offers a comprehensive overview of current prevention and treatment strategies for EVRB, providing valuable insights for clinicians and healthcare professionals.

Creation of 6-10mm Diameter Transjugular Intrahepatic Portosystemic Shunts Using a Novel TIPS Stent Graft in a Swine Model

PurposeTo assess the delivery, function, and patency of a new expanded polytetrafluoroethylene encapsulated TIPS stent- graft ("Liverty") in an animal model. Materials and MethodsTIPS were created in 2 successive groups: 14 single & 10 overlapping devices, in swine weighing 52-64kg. Explants occurred at 30 (n=10) and 60 (n=14) days. These were evaluated by histomorphometry and histopathologic evaluations, and electron microscopy. ResultsSeven 6mm, five 7mm, and twelve 10mm diameter TIPS were created using varied human TIPS access sets without complications; both sheathed and unsheathed advancement and deployment of the devices within liver tracts. One animal was sacrificed at 35d due to encephalopathy; remainder survived to endpoints. 22/24 TIPS were patent at 30 and 60-day endpoints; Mean stenosis at 30 days was 13.3% +/- 10.1%, and for 60 days was 18.44% ± 5.04%. Two shunts were occluded by tissue overgrowth at unstented native hepatic vein end and downgrowth into TIPS. Histology and electron microscopy showed well-apposed, incorporated devices lined with smooth, uniform neointimal tissue averaging 0.48mm (single devices) and 0.74mm thick (overlapped devices) with minimal adventitial inflammation. ConclusionThe new Liverty TIPS stent graft was straightforward to deploy for TIPS creation and resulted in patent 6,7, and 10mm diameter shunts in both single and overlapping configurations. One- and 2-month histology showed desired tissue healing without in-stent stenosis.

Beyond MELD Score: Association of Machine Learning-derived CT Body Composition with 90-Day Mortality Post Transjugular Intrahepatic Portosystemic Shunt Placement.

To determine the association of machine learning-derived CT body composition and 90-day mortality after transjugular intrahepatic portosystemic shunt (TIPS) and to assess its predictive performance as a complement to Model for End-Stage Liver Disease (MELD) score for mortality risk prediction. This retrospective multi-center cohort study included patients who underwent TIPS from 1995 to 2018 and had a contrast-enhanced CT abdomen within 9months prior to TIPS and at least 90 days of post-procedural clinical follow-up. A machine learning algorithm extracted CT body composition metrics at L3 vertebral level including skeletal muscle area (SMA), skeletal muscle index (SMI), skeletal muscle density (SMD), subcutaneous fat area (SFA), subcutaneous fat index (SFI), visceral fat area (VFA), visceral fat index (VFI), and visceral-to-subcutaneous fat ratio (VSR). Independent t-tests, logistic regression models, and ROC curve analysis were utilized to assess the association of those metrics in predicting 90-day mortality. A total of 122 patients (58 ± 11.8, 68% male) were included. Patients who died within 90 days of TIPS had significantly higher MELD (18.9 vs. 11.9, p < 0.001) and lower SMA (123 vs. 144.5, p = 0.002), SMI (43.7 vs. 50.5, p = 0.03), SFA (122.4 vs. 190.8, p = 0.009), SFI (44.2 vs. 66.7, p = 0.04), VFA (105.5 vs. 171.2, p = 0.003), and VFI (35.7 vs. 57.5, p = 0.02) compared to those who survived past 90 days. There were no significant associations between 90-day mortality and BMI (26 vs. 27.1, p = 0.63), SMD (30.1 vs. 31.7, p = 0.44), or VSR (0.97 vs. 1.03, p = 0.66). Multivariable logistic regression showed that SMA (OR = 0.97, p < 0.01), SMI (OR = 0.94, p = 0.03), SFA (OR = 0.99, p = 0.01), and VFA (OR = 0.99, p = 0.02) remained significant predictors of 90-day mortality when adjusted for MELD score. ROC curve analysis demonstrated that including SMA, SFA, and VFA improves the predictive power of MELD score in predicting 90-day mortality after TIPS (AUC, 0.84; 95% CI: 0.77, 0.91; p = 0.02). CT body composition is positively predictive of 90-day mortality after TIPS and improves the predictive performance of MELD score. Level 3, Retrospective multi-center cohort study.

Sleep disturbance in patients with cirrhosis and transjugular intrahepatic portosystemic shunt

BackgroundSleep disturbance (SD) is a common occurrence in individuals with cirrhosis and significantly impacts their quality of life. Datas regarding post transjugular intrahepatic portosystemic shunt (TIPS) SD are scarce. This study aimed to explore the incidence and outcomes of post-TIPS SD.MethodsFrom August 2018 to November 2019, 73 patients who underwent TIPS were prospectively recruited for the study. Sleep quality was evaluated via the Pittsburgh Sleep Quality Index (PSQI), and the presence of hepatic encephalopathy was evaluated according to the West Haven criteria before and after the TIPS procedure.ResultsNineteen patients (26%) experienced new-onset SD after TIPS, with a median latency of 67 (40–98) days from the procedure. The median time from TIPS creation to occurrence was 67 (40–98) days. Minimal hepatic encephalopathy (MHE) post-TIPS emerged as an independent predictor of SD, with an odds ratio of 3 (95% CI: 1.04–8.78, P = 0.046). Notably, five of the six (83%) patients with SD experienced improvement after being administered eszopiclone. Ten of the thirteen (77%) patients with SD improved spontaneously without treatment. Furthermore, the prevalence of MHE was significantly greater among patients with SD than among those without SD (58% vs. 31%, P = 0.04).ConclusionsSD is prevalent in patients who undergo TIPS. MHE is an independent risk factor for the development of SD post-TIPS. Eszopiclone may be a safe and effective treatment option for patients with SD after TIPS. The study was registered with ClinicalTrials.gov under the identifier NCT03685994, with a registration date of September 23, 2018.

Predicting Portal Pressure Gradient in Patients with Decompensated Cirrhosis: A Non-invasive Deep Learning Model.

A high portal pressure gradient (PPG) is associated with an increased risk of failure to control esophagogastric variceal hemorrhage and refractory ascites in patients with decompensated cirrhosis. However, direct measurement of PPG is invasive, limiting its routine use in clinical practice. Consequently, there is an urgent need for non-invasive techniques to assess PPG. To develop and validate a deep learning model that predicts PPG values for patients with decompensated cirrhosis and identifies those with high-risk portal hypertension (HRPH), who may benefit from early transjugular intrahepatic portosystemic shunt (TIPS) intervention. Data of 520 decompensated cirrhosis patients who underwent TIPS between June 2014 and December 2022 were retrospectively analyzed. Laboratory and imaging parameters were used to develop an artificial neural network model for predicting PPG, with feature selection via recursive feature elimination for comparison experiments. The best performing model was tested by external validation. After excluding 92 patients, 428 were included in the final analysis. A series of comparison experiments demonstrated that a three-parameter (3P) model, which includes the international normalized ratio, portal vein diameter, and white blood cell count, achieved the highest accuracy of 87.5%. In two distinct external datasets, the model attained accuracy rates of 85.40% and 90.80%, respectively. It also showed notable ability to distinguish HRPH with an AUROC of 0.842 in external validation. The developed 3P model could predict PPG values for decompensated cirrhosis patients and could effectively distinguish HRPH.

Comparison of outcomes for transjugular intrahepatic portosystemic shunt creation: Viatorr versus Fluency versus a bare stent/Fluency stent combination

PurposeTo compare clinical outcomes of transjugular intrahepatic portosystemic shunt (TIPS) created with the single covered-uncovered stent (Viatorr TIPS Endoprosthesis) versus covered stent (Fluency) versus a combination of covered and uncovered stent.Materials and methodsFrom May 2016 and July 2019, a total of 180 liver cirrhosis patients with recurrent variceal bleeding underwent TIPS creation with single covered-uncovered stent (n = 63) or covered stent (n = 41) or a covered and uncovered stent combination (n = 76). Shunt dysfunction, rebleeding, overt hepatic encephalopathy and mortality was estimated using the Kaplan–Meier method and compared with the log-rank test.ResultsThe difference of baseline characteristics among these three groups were not significant. The included patients had a median age of 51 years (IQR 43–61), and 101 (56.1%) were men. The 1-year and 2-year shunt dysfunction rates were 1.6% and 3.2% in the single covered-uncovered stent group, 7.3% and 7.3% in the covered stent group and 5.3% and 6.6% in the combination group, respectively. There was no significant difference among groups [Hazard Ratio (HR) (95%CI): 1 vs 2.29 (0.38 − 13.72) vs 2.10 (0.41 − 10.83); P = 0.913]. No significant differences in the incidence of all-cause rebleeding were observed between the groups at 1 year (Viatorr vs Fluency vs combination: 11.1% vs 17.1% vs 10.5%) as well as 2 years (15.9% vs 17.1% vs 11.8%), with the HR (95%CI) being 1 vs 1.27 (0.5—3.21) vs 0.74 (0.30–1.82); P = 0.475). The 1-year and 2-year incidence of overt hepatic encephalopathy were 30.2% and 30.2% in the single covered-uncovered stent group, 22.0% and 22.0% in the covered stent group and 25.0% and 25.0% in the combination group, respectively. However, there was no significant difference among these three groups (P = 0.402). In addition, there was no significant difference in the 1-year and 2-year mortality (6.3% and 7.9% vs. 4.9% and 9.8% vs. 6.6% and 9.2%, P = 0.606).ConclusionNo significant difference was observed among different stent groups. Fluency covered stent and the generic bare stent/Fluency covered stent was not an unreasonable alternative to the Viatorr stent for TIPS creation.

Preemptive Transjugular Intrahepatic Portosystemic Shunt in Variceal Bleeding: A Real-World Study in a Tertiary Hospital

Introduction: Several studies have highlighted the potential benefits of early prophylactic transjugular intrahepatic portosystemic shunt (preemptive TIPS) placement in reducing morbidity and mortality following variceal bleeding (VB). Baveno VII recommends its placement less than 72 h after VB (Child-Pugh class C <14 or class B >7 plus active bleeding). This study aimed to evaluate the effectiveness of preemptive TIPS compared to a control group in a referral center. Methods: The control group included cirrhotic patients with VB and Child-Pugh class C or B with active bleeding, retrospectively selected between 2016 and 2022 and divided into 2 subgroups: those that never underwent TIPS placement during the course of their illness (subgroup A) and those submitted to TIPS placement due to rebleeding (subgroup B). Additionally, patients who received preemptive TIPS placement between August 2022 and January 2024 were prospectively included into the preemptive transjugular intrahepatic portosystemic shunt (pTIPS) group. Results: A total of 47 patients were included, 19 (40.4%) in the pTIPS group and 28 (59.6%) in control group (17 in subgroup A). There were no differences in baseline characteristics between the groups, except hepatic encephalopathy that was significantly higher in the control group when compared to the pTIPS group: 19 (67.9%) versus 6 (31.6%), p = 0.014. Early rebleeding rates were significantly lower in the pTIPS group: 1 (5.3%) versus 13 (46.4%) (p = 0.002). There were no significant differences in 6-week survival between the groups: 25 (89.3%) versus 17 (89.5%), p = 0.683. Regarding hepatic encephalopathy, no significant differences were observed between the control and the pTIPS group: 6 (21.4%) versus 4 (21.1%), p = 0.632, even when comparing subgroup A (4, 23.5%) with the pTIPS group (p = 0.432). Conclusion: This real-world study highlights the potential benefits of preemptive TIPS placement in reducing early relapse of VB, thereby lowering morbidity and complications. The findings advocate for the proactive incorporation of preemptive TIPS into clinical practice to optimize patient outcomes following VB.
