Background: Malnutrition is common in patients with cirrhosis, eventually leading to sarcopenia and loss of bone mass., Aims: The aims of this study was the assessment of body composition (BC) and bone mineral density (BMD) in patients with decompensated cirrhosis and the prognostic impact on survival after transjugular intrahepatic portosystemic shunt (TIPS) implantation., Methods: BMD and BC of 107 patients with cirrhosis undergoing TIPS implantation were prospectively analyzed by dual-energy X-ray absorptiometry. The prevalence and predisposing risk factors for reduced BMD and sarcopenia were assessed. Impact on 12-month survival after TIPS implantation was evaluated., Results: Sarcopenia was diagnosed in 48.6 % of the patients with a predominance of male patients (58.7% vs. 25.0 %, p = 0.001). 67.2 % had reduced BMD. Low BMI was independently associated with sarcopenia (OR 0.751 (95 % CI: 0.662;0.852), p < 0.001) and reduced BMD (OR 0.851 (0.773;0.937), p = 0.001). Patients with reduced BMD, but not sarcopenia, had impaired 12-month survival after TIPS-implantation (61.2% vs. 82.9 %, p = 0.030). Subgroup analysis showed that this was especially valid for female patients., Conclusions: Sarcopenia and reduced BMD are frequently observed in patients with decompensated cirrhosis. Reduced BMD negatively affects post-TIPS survival. Since malnutrition is a leading cause, assessment of nutritional status and specific treatment should be included in clinical practice., Competing Interests: Conflicts of Interest DB: lecture fees from W.

Introduction: The recently developed Freiburg Index of Post-TIPS Survival (FIPS) allows improved risk classification of patients with decompensated cirrhosis allocated to transjugular intrahepatic portosystemic shunt (TIPS) implantation. This study investigated the prognostic value of the FIPS in patients hospitalized with acute decompensation of cirrhosis (AD), outside the setting of TIPS implantation., Methods: A total of 1133 patients with AD were included in a retrospective, multi-centre study. Ninety-day, 180-day and 1-year mortality were recorded and the FIPS' performance in predicting mortality at these time points was analysed using ROC analyses., Results: Ninety-day, 180-day and 1-year mortality were 17.7%, 24.4% and 30.8%. Uni- and multivariable Cox regression models showed that the FIPS independently predicted 1-year mortality in the study cohort (HR 1.806, 95% CI 1.632-1.998, p < .0001). In ROC analyses, the FIPS offered consistently high performance in the prediction of mortality within 1 year after AD (area under the receiver operator characteristic [AUROC]: 1-year mortality .712 [.679-.746], 180-day mortality .740 [.705-.775] and 90-day mortality .761 [.721-.801]). In fact, in the subgroup of patients presenting with variceal bleeding, the FIPS even showed significantly improved discriminatory performance in the prediction of long-term mortality (AUROC 1-year mortality: .782 [.724-.839]) in comparison with established prognostic scores, such as the CLIF-C AD score (.724 [.660-.788], p = .0071) or MELD 3.0 (.726 [.662-.790], p = .0042)., Conclusions: The FIPS accurately predicts mortality in patients with AD and seems to offer superior prognostication of long-term mortality in patients with variceal bleeding., (© 2024 The Author(s).

Background and Aims: About 20% of patients develop cardiac decompensation within the first year after transjugular intrahepatic portosystemic shunt (TIPS) insertion. However, risk factors for cardiac decompensation remain poorly defined. We aimed to evaluate predictors of cardiac decompensation after TIPS insertion in a large, well-defined cohort of patients with liver cirrhosis., Methods: 234 cirrhotic patients who received a TIPS at Hannover Medical School were retrospectively followed up for one year to assess the incidence of cardiac decompensation. Echocardiographic parameters and established diagnostic criteria for cardiac impairment (e.g. by the American Society of Echocardiography/ European Association of Cardiovascular Imaging (ASE/EACVI)) were investigated for an association with cardiac decompensation in a competing risk analysis. Survival was analyzed using a multivariable cox regression analysis adjusting for Freiburg index of post-TIPS survival., Results: Predominant TIPS indication was ascites (83%). Median age was 59 years, median MELD-score 12% and 58% were male. Overall, 41 patients (18%) developed cardiac decompensation within one year after TIPS insertion. Diastolic dysfunction according to the ASE/EACVI was diagnosed in 26% of patients at baseline and was linked to a significantly higher risk for cardiac decompensation (p = 0.025) after TIPS. When investigating individual echocardiographic baseline parameters, only pathological E/A (<0.8 or >2) was identified as a risk factor for cardiac decompensation (p = 0.015). Mortality and liver transplantation (n = 50) were significantly higher among patients who developed cardiac decompensation (HR = 5.29, p < 0.001) as well as in patients with a pathological E/A (HR = 2.34, p = 0.006). Cardiac high-risk status (44% of patients) was strongly linked to cardiac decompensation (HR = 2.93, p = 0.002) and mortality (HR = 2.24, p = 0.012)., Conclusion: Cardiac decompensation after TIPS is a frequent and important complication and is associated with reduced survival. American Society of Echocardiography/EACVI criteria and E/A seem to be the best parameters to predict the cardiac risk in cirrhotic patients undergoing TIPS insertion., (© 2023 The Authors.

Background and Aims: Transjugular intrahepatic portosystemic shunt (TIPS) implantation is an established procedure to treat portal hypertension. Impact of administration of aspirin on transplant-free survival after TIPS remains unknown., Methods: A multicenter retrospective analysis including patients with TIPS implantation between 2011 and 2018 at three tertiary German Liver Centers was performed. N = 583 patients were included. Survival analysis was performed in a matched cohort after propensity score matching. Patients were grouped according to whether aspirin was (PSM-aspirin-cohort) or was not (PSM-no-aspirin-cohort) administered after TIPS. Primary endpoint of the study was transplant-free survival at 12 months after TIPS., Results: Aspirin improved transplant-free survival 12 months after TIPS with 90.7% transplant-free survival compared to 80.0% (p = 0.001) after PSM. Separated by TIPS indication, aspirin did improve transplant-free survival in patients with refractory ascites significantly (89.6% vs. 70.6% transplant-free survival, p < 0.001), while no significant effect was observed in patients with refractory variceal bleeding (91.1% vs. 92.2% transplant-free survival, p = 0.797)., Conclusion: This retrospective multicenter study provides first data indicating a beneficial effect of aspirin on transplant-free survival after TIPS implantation in patients with refractory ascites., (© 2022.

Purpose of Review: This review summarizes indications and contraindications for implantation of transjugular intrahepatic portosystemic shunt (TIPS). Further, patient selection strategies are discussed., Recent Findings: TIPS implantation is a highly effective treatment for portal hypertension. Main indications are ascites and variceal bleeding in patients with liver cirrhosis. There is growing evidence that early TIPS implantation after variceal bleeding is associated with an improved survival (preemptive TIPS).Preliminary data also suggest that an analogous concept of early TIPS implantation may be beneficial for patients with ascites. Further, well-selected patients with acute or chronic nonmalignant portal vein thrombosis can be effectively treated with TIPS implantation. In contrast, there is generally no recommendation for TIPS implantation in patients with hepatic veno-occlusive disease, noncirrhotic portal hypertension or prior before surgery to avoid complications of portal hypertension. Apart from evidence-based patient selection, the newly developed FIPS score can be an objective component in decision-making., Summary: Consideration of well-established indications and contraindications for TIPS implantation as well as concise patient selection criteria are essential for an optimal outcome after TIPS implantation., (Copyright © 2022 Wolters Kluwer Health, Inc.

Purpose: This study compares the safety and efficacy of the ePTFE-covered self-expansible nitinol stent (VIATORR® Controlled Expansion, Gore, Flagstaff, USA) with the ePTFE-covered, balloon-expandable, metallic stent (BeGraft peripheral, Bentley, Hechingen, Germany) for the creation of the transjugular intrahepatic portosystemic shunt (TIPS)., Material and Methods: From September 2016 to December 2020, 72 consecutive patients receiving TIPS for acute variceal bleeding (rescue and early TIPS, n = 15) or for prophylaxis of variceal rebleeding (n = 57) were enrolled. The main contraindications were patients with vascular liver disease (portal vein thrombosis and Budd-Chiari syndrome). Forty patients (55.6%) received a Viatorr CX stent and 32 patients (44.4%) a BeGraft peripheral stent. Safety endpoints were technical and clinical adverse events and early deaths within 30 days after TIPS implantation. Efficacy endpoints were rebleeding rates, recurrence of large varices requiring endoscopic band ligation, or TIPS revision., Results: Groups receiving the Viatorr CX or BeGraft peripheral stent were comparable in all respects except the TIPS indication for acute variceal bleeding (5% vs. 25%, p = 0.015). All patients had a successful intervention, and the physical variables of stent implantation (intervention and fluoroscopy time, reduction of the portosystemic pressure gradient) as well as adjunctive embolization of varices were similar in both groups. Severe clinical complications (Viatorr CX: 5% vs. BeGraft peripheral: 3.1%, p = 0.692), post-TIPS hepatic encephalopathy (12.5% vs. 18.8%, p = 0.743) and death (5% vs. 0%, p = 0.793) were not different between Viatorr CX and BeGraft peripheral groups. With respect to efficacy, freedom from rebleeding and from variceal band ligation during follow-up (100% vs. 100%, p = 1.0), as well as the need for shunt revision (10.5% vs. 18.8%, p = 0.327), was comparable., Conclusion: Compared to the present gold standard, the Viatorr CX stent, the balloon-expandable BeGraft peripheral stent, showed similar results with respect to safety and efficacy., (© 2021.

Background & Aims: Transjugular intrahepatic portosystemic shunt (TIPS) implantation is an effective and safe treatment for complications of portal hypertension. Survival prediction is important in these patients as they constitute a high-risk population. Therefore, the aim of our study was to develop an alternative prognostic model for accurate survival prediction after planned TIPS implantation., Methods: A total of 1,871 patients with de novo TIPS implantation for ascites or secondary prophylaxis of variceal bleeding were recruited retrospectively. The study cohort was divided into a training set (80% of study patients; n = 1,496) and a validation set (20% of study patients; n = 375). Further, patients with early (preemptive) TIPS implantation due to variceal bleeding were included as another validation cohort (n = 290). Medical data and overall survival (OS) were assessed. A Cox regression model was used to create an alternative prediction model, which includes significant prognostic factors., Results: Age, bilirubin, albumin and creatinine were the most important prognostic factors. These parameters were included in a new score named the Freiburg index of post-TIPS survival (FIPS). The FIPS score was able to identify high-risk patients with a significantly reduced median survival of 5.0 (3.1-6.9) months after TIPS implantation in the training set. These results were confirmed in the validation set (median survival of 3.1 [0.9-5.3] months). The FIPS score showed better prognostic discrimination compared to the Child-Pugh, MELD, MELD-Na score and the bilirubin-platelet model. However, the FIPS score showed insufficient prognostic discrimination in patients with early TIPS implantation., Conclusions: The FIPS score is superior to established scoring systems for the identification of high-risk patients with a worse prognosis following elective TIPS implantation., Lay Summary: Implantation of a transjugular intrahepatic portosystemic shunt (TIPS) is a safe and effective treatment for patients with cirrhosis and clinically significant portal hypertension. However, risk stratification is a major challenge in these patients as currently available scoring systems have major drawbacks. Age, bilirubin, albumin and creatinine were included in a new risk score which was named the Freiburg index of post-TIPS survival (FIPS). The FIPS score can identify patients at high risk and may guide clinical decision making., Competing Interests: Conflict of interest JT: Grants: Gore, Consultant: Martins Pharma, Ironwood, Gore, Alexion, BMS, Grifols, Sequana Medicals, Versantis, Sponsored lectures (National or International): Gilead, Gore, Alexion, BMS, Grifols, Sequana Medicals, Norgine, Intercept.

Prognostic assessment of patients with liver cirrhosis allocated for implantation of a transjugular intrahepatic portosystemic shunt (TIPS) is a challenging task in clinical practice. The aim of our study was to assess the prognostic value of the CLIF-C AD (Acute Decompensation) score in patients with TIPS implantation. Transplant-free survival (TFS) and 3-month mortality were reviewed in 880 patients who received de novo TIPS implantation for the treatment of cirrhotic portal hypertension. The prognostic value of the CLIF-C AD score was compared with the Model for End-Stage Liver Disease (MELD) score, Child-Pugh score, and albumin-bilirubin (ALBI) score using Harrell's C concordance index. The median TFS after TIPS implantation was 40.0 (34.6-45.4) months. The CLIF-C AD score (c = 0.635 [0.609-0.661]) was superior in the prediction of TFS in comparison to MELD score (c = 0.597 [0.570-0.623], P  = 0.006), Child-Pugh score (c = 0.579 [0.552-0.606], P  < 0.001), and ALBI score (c = 0.573 [0.545-0.600], P  < 0.001). However, the CLIF-C AD score did not perform significantly better than the MELD-Na score (c = 0.626 [0.599-0.653], P  = 0.442). There were no profound differences in the scores' ranking with respect to indication for TIPS implantation, stent type, or underlying liver disease. Subgroup analyses revealed that a CLIF-C AD score >45 was a predictor of 3-month mortality in the supposed low-risk group of patients with a MELD score ≤12 (14.7% vs. 5.1%, P  < 0.001). Conclusion: The CLIF-C AD score is suitable for prognostic assessment of patients with cirrhotic portal hypertension receiving TIPS implantation. In the prediction of TFS, the CLIF-C AD score is superior to MELD score, Child-Pugh score, and ALBI score but not the MELD-Na score., (© 2021 The Authors.

For 30 years the transjugular intrahepatic portosystemic shunt (TIPS) is successfully used for the treatment of portal hypertension. Indication for TIPS in relation to variceal bleeding and refractory ascites is scientifically documented and defined by national and international guidelines. For rare indications such as hepatorenal syndrome, portal vein thrombosis or the neodjuvant TIPS larger evidence-based studies are missing. An important contraindication and the leading clinical complication after TIPS is the development of hepatic encephalopathy (HE). Reduction of post-TIPS HE is therefore aimed through development of further technical enhancements of the TIPS-stents., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (© Georg Thieme Verlag KG Stuttgart · New York.)

Background: To evaluate medical versus interventional treatment (transjugular thrombus fragmentation, local thrombolysis with or without stent implantation) in patients with acute non-cirrhotic, non-malignant portal vein thrombosis (PVT)., Methods: This prospective, observational study enrolled 65 patients with acute (<28 days since begin of symptoms, no cavernoma) PVT in nine centres. Thirty patients received medical treatment and 35 patients received interventional treatment. PVT was graded into grade 1: short thrombosis and incomplete occlusion of the vessel lumen and grade 2: extended thrombosis or complete occlusion. Treatment response was classified as partial or complete, if thrombosis was reduced by one grade or to <25% of the vessel diameter respectively., Results: Partial and complete response rates were 7% and 30% in the medical compared to 17% and 54% (P < 0.001) in the interventional treatment group. In the multivariate analysis, interventional treatment showed a strong positive (OR 4.32, P < 0.016) and a myeloproliferative aetiology a negative (OR 0.09, P = 0.006) prediction of complete response. Complications were rare in the medical group and consisted of septicaemia and upper gastrointestinal bleeding of unknown origin in one patient each. Interventional treatment was accompanied by mild and self-limiting bleeding complications in nine patients, moderate intra-abdominal bleeding requiring transfusions (2 units) in one patient and peritoneal bleeding requiring surgical rescue in one patient. Four patients in each group developed intestinal gangrene requiring surgery. One patient died 52 days after unsuccessful interventional treatment., Conclusions: Compared to medical treatment alone, interventional treatment doubled response rates at the cost of increased bleeding complications., (© 2020 The Authors.

Adjuvant embolization of varices may reduce rebleeding in patients with a transjugular intrahepatic portosystemic shunt (TIPS). The aim of this study was to investigate the efficacy and the risks of adjuvant variceal embolization at TIPS implantation using bucrylate., Patients and Methods: The retrospective study evaluated 104 of 237 cirrhotic patients with TIPS for variceal bleeding who received adjuvant bucrylate embolization. For TIPS creation, bare stents were used in 35 patients (33.7%) and covered stents in 69 patients (66.3%) patients. Isolated gastric varices were seen in 10 patients (9.6%)., Results: Six patients (5.8%) rebled during a median follow-up time of 26 months (1-57 months). Rebleeding occurred in 14% (5/35) of patients with a bare stent but only in 1.4% (1/69) of patients with a covered stent. The 1- and 2-year rebleeding rates of all patients were 0.9 and 2.9% and of patients receiving a bare stent were 2.9 and 8.6%, respectively. Bucrylate migration was seen in 13 patients (12.5%). In 9 of these patients (8.7%), asymptomatic lung embolization occurred. This was rare in patients with esophageal varices (3.1%) but frequent (60%) in patients with isolated gastric varices and a spontaneous splenorenal shunt., Conclusions: Our results suggest that adjuvant embolization using bucrylate is effective and delays variceal rebleeding. The general use of covered stents, however, alleviates the utility of adjuvant bucrylate embolization which may be restricted to patients with a high risk of rebleeding indicated by large varices, active, acute or recent variceal bleeding and advanced cirrhosis. Bucrylate should not be used in isolated gastric varices because it bears a high risk of migration into the lungs.

Purpose: This study investigates the behaviour of self-expanding nitinol stents at the time of TIPS-implantation and thereafter., Methods: Hundred consecutive patients with cirrhosis receiving a TIPS revision were included. The smallest stent diameter was measured radiologically immediately after implantation and before shunt revision. Accuracy of the measurement was assessed by comparing the nominal stent diameter with the largest stent diameter measured at the time of revision., Results: Pearson correlation between largest measured and nominal diameters was excellent (r=0.952, p<0.001) showing that measurements are accurate. At TIPS implantation all stents were markedly underdilated reaching only 76-92% of their nominal diameter. Smallest measured diameters were similar (8mm) irrespective of the nominal diameter (8, 9, 10mm) of the stent. In addition, smallest diameters of 10mm stents were similar irrespective whether 8, 9 or 10mm balloons were used. During a mean follow-up of 12.7±17.8months (median 3 months, range 1-81) stents expanded by 0.5-1.6mm dependent on the nominal stent size (8, 9, 10mm) and the grade of primary underdilation. No significant difference was found between Viatorr and bare stents., Conclusions: At TIPS-implantation, the compliance of the surrounding tissue predominantly determines the stent diameter. The nominal size of the stent or the dilatation balloon has little influence. Accurate adjustment of a desired pressure gradient is, therefore, not possible. During follow-up, stents expand towards their nominal diameter questioning the usefulness of underdilation., (Copyright © 2017 Elsevier B.V. All rights reserved.)
