Abstract
Hepatic encephalopathy (HE) is a clinically severe and devastating complication of decompensated liver disease affecting mortality, quality of life for patients and families, hospital admission rates, and overall health-care costs globally. Depending on the cause of HE, several medical treatment options have been developed and become available. In some refractory HE, such as spontaneous portosystemic shunt-related HE (SPSS-HE) or posttransjugular intrahepatic portosystemic shunt HE (post-TIPS HE), advanced interventional radiology (IR) procedures have been used, and shown to be effective in these conditions. This review presents 2 effective IR procedures for managing SPSS-HE and post-TIPS HE.

Abstract
Hepatic encephalopathy is described by a broad spectrum of neurological and psychiatric aberrations resulting due to advanced liver dysfunction. It is a neurological disorder due to hepatic insufficiency and/or portosystemic shunts. Its clinical presentation includes neuropsychiatric dysfunction ranging from subclinical changes to comatose state. It is a sign of poor prognosis in cirrhotics with a high 1-year mortality. Each episode of hepatic encephalopathy leads to high hospitalization rate, poor prognosis and raised burden of healthcare. Primary prophylaxis is prevention of initial occurrence and secondary prophylaxis is prevention of reappearance of hepatic encephalopathy in subjects who had prior history. Early detection and management of triggers is very important in the treatment of hepatic encephalopathy. The initial choice of treatment is still lactulose, as it is effective in minimal, overt, and recurrent hepatic encephalopathy. Rifaximin is equally effective as lactulose in managing hepatic encephalopathy and is better tolerated. Branch chain amino acids are beneficial in subjects who are protein intolerant. L-ornithine L-aspartate and probiotics are also useful in the management of hepatic encephalopathy. Rifaximin along with lactulose is effective in managing overt and recurrent hepatic encephalopathy. Large portosystemic shunts embolization and liver transplant is efficacious in certain group of patients. Nutritional therapy and fecal microbiota transplantation are newer therapies for hepatic encephalopathy but the evidences are limited, more research is required to prove their efficacy. Involvement of hospital pharmacists, telemedicine, and providing education are also beneficial in managing hepatic encephalopathy.

Int J Surg 2024; 110:1149-1158. [PMID: 37924494 PMCID: PMC10871647 DOI: 10.1097/js9.0000000000000865] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2023] [Accepted: 10/22/2023] [Indexed: 11/06/2023]
Abstract
BACKGROUND Cirrhosis is a chronic disease characterized by chronic liver inflammation and diffuse fibrosis. A combination of vasoactive drugs, preventive antibiotics, and endoscopy is the recommended standard treatment for patients with acute variceal bleeding; however, this has been challenged. We compared the effects of early transjugular intrahepatic portosystemic shunt (TIPS), non-early TIPS, and standard treatment in patients with cirrhosis and acute variceal bleeding. MATERIALS AND METHODS The present network meta-analysis was conducted in accordance with the criteria outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Assessing the methodological quality of systematic reviews guidelines. The review has been registered with the International Prospective Register of Systematic Reviews. The PubMed, Embase, Cochrane Library, ClinicalTrials.gov, and World Health Organization-approved trial registry databases were searched for randomized controlled trials (RCTs) evaluating early TIPS, non-early TIPS, and standard treatment in patients with cirrhosis and acute variceal bleeding. RESULTS Twenty-four RCTs (1894 patients) were included in the review. Compared with standard treatment, early TIPS [odds ratio (OR), 0.53; 95% credible interval (Cr), 0.30-0.94; surface under the cumulative ranking curve (SUCRA), 98.3] had a lower risk of all-cause mortality (moderate-to-high-quality evidence), and early TIPS (OR, 0.19; 95% CrI, 0.11-0.28; SUCRA, 98.2) and non-early TIPS (OR, 0.30; 95% CrI, 0.23-0.42; SUCRA, 1.8) were associated with a lower risk of rebleeding (moderate-to-high-quality evidence). Early TIPS was not associated with a reduced risk of hepatic encephalopathy, and non-early TIPS (OR, 2.78; 95% CrI, 1.89-4.23, SUCRA, 0) was associated with an increased incidence of hepatic encephalopathy (moderate-to-high-quality evidence). There was no difference in the incidence of new or worsening ascites (moderate-to-high-quality evidence) among the three interventions. CONCLUSION Based on the moderate-to-high quality evidence presented in this study, early TIPS placement was associated with reduced all-cause mortality [with a median follow-up of 1.9 years (25th-75th percentile range 1.9-2.3 years)] and rebleeding compared to standard treatment and non-early TIPS. Although early TIPS and standard treatment had a comparable incidence of hepatic encephalopathy, early TIPS showed superiority over non-early TIPS in this aspect. Recent studies have also shown promising results in controlling TIPS-related hepatic encephalopathy. However, it is important to consider individual patient characteristics and weigh the potential benefits against the risks associated with early TIPS. Therefore, we recommend that clinicians carefully evaluate the patient's condition, considering factors such as severity of variceal bleeding, underlying liver disease, and overall clinical status, before making a treatment decision. Further well-designed RCTs comparing early TIPS with non-early TIPS are needed to validate these findings and provide more definitive guidance.

Abstract
INTRODUCTION The purpose of this study was to determine the effect of proximal splenic artery embolization (SAE) in cirrhotic patients with splenomegaly who underwent surgical laparotomy. MATERIAL AND METHODS This retrospective observational study included 8 cirrhotic patients with splenomegaly. They underwent proximal SAE before- (n = 6) or after (n = 2) laparotomy. Vascular plugs or coils were placed in the proximal splenic artery. The diameter of the portal vein and the splenic volume were recorded. Clinical outcome assessments included platelet counts, the model for end-stage liver disease (MELD) score, and complications. RESULTS After embolization, the portal venous diameter was significantly smaller (pre: 13.6 ± 2.7 mm, post: 12.5 ± 2.3 mm, p = 0.023), the splenic volume was significantly decreased (pre: 463.2 ± 145.7 ml, post: 373.3 ± 108.5 ml, p = 0.008) and the platelet count was significantly higher (pre: 69.6 ± 30.8 × 103/μl, post: 86.8 ± 27.7 × 103/μl, p = 0.035). Before embolization, the median MELD score was 12; after embolization, it was 11 (p = 0.026). No patient developed post-treatment complications after embolization. CONCLUSIONS The reduction of hypersplenism by perioperative proximal SAE may be safe and reduce the surgical risk in cirrhotic patients with splenomegaly.

Life-threatening variceal bleeding after liver transplantation and extensive portal vein thrombosis: Desperate times call for desperate measures. Pediatr Transplant 2023; 27:e14555. [PMID: 37291909 DOI: 10.1111/petr.14555] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2023] [Revised: 05/08/2023] [Accepted: 05/22/2023] [Indexed: 06/10/2023]
Abstract
BACKGROUND The management of complex, intra- and extrahepatic portal vein thrombosis (PVT) after liver transplantation (LT) is challenging. Although most of the patients remain asymptomatic or oligosymptomatic in the chronic setting, some of them may develop severe portal hypertension and related complications, notably gastrointestinal (GI) bleeding. In the emergency scenario, clinical and endoscopic treatments as well as intensive support constitute the bases of conservative management, while more definitive treatment options such as surgical shunting and retransplantation are related to high morbidity rates. Transjugular intrahepatic portosystemic shunt (TIPS) was largely considered of limited role due to technical difficulties arising from extensive PVT. Recently, however, new minimally invasive image-guided techniques emerged, allowing portal vein recanalization and TIPS creation simultaneously (TIPS-PVR), even in complex PVT pretransplant patients. METHODS Herein, we describe a novel indication for TIPS-PVR in a post-LT adolescent presenting with life-threatening, refractory GI bleeding. RESULTS The patient presented with complete resolution of the hemorrhagic condition after the procedure, with no deterioration of hepatic function or hepatic encephalopathy. Follow-up Doppler ultrasound after TIPS-PVR showed normal hepatopetal venous flow within the stents, and no evidence of complications, including intraperitoneal or peri splenic bleeding. CONCLUSIONS This report describes the feasibility of TIPS-PVR in the post-LT scenario complicated by extensive PVT. In this case, a complete resolution of the life-threatening GI bleeding was achieved, with no major complications. Other patients with complex chronic PVT might benefit from the use of the described technique, but further studies are required to determine the correct timing and indications of the procedure, eventually before the occurrence of life-threatening complications.

Abstract
Hepatic encephalophaty (HE) is a neuropsychiatric syndrome with a prevalence in the cirrhotic population ranging from 20 to 80%. HE is a cause of inappropriate hospitalization, caregiver burdening and increased social costs. There is need to create dedicated care pathways to better manage patients and support family caregivers. The data used for the preparation of this diagnostic therapeutic assistance path (DTAP) are based on a detailed analysis of the scientific literature published before June 30, 2022 (PubMed, Web of Science, Scopus, Google Scholar). Furthermore, in the process of developing this work, we consulted in particular the guidelines/ position papers of International Society for Hepatic Encephalopathy and Nitrogen Metabolism (ISHEN), Italian Association for the Study of the Liver (AISF), European Association for the Study of the Liver (EASL), American Association for the Study of Liver Diseases (AASLD), Italian Society on Alcohol (Società Italiana di Alcologia [SIA]) and other relevant papers. DTAP was created based on the most recent recommendations of the international scientific literature. The present DTAP highlight the need for a multidisciplinary activity integrated with territorial medicine in close connection with caregivers. This guarantees improved therapeutic adherence, hospital readmission reduction, improved quality of life for patients and caregivers and a significant reduction in costs.

Abstract
Congenital portosystemic shunts (CPSS) may produce a variety of severe, clinically detrimental presentations. When indicated, closure is recommended; however, if the intrahepatic portal venous system (IPVS) is underdeveloped complete closure may not be possible and may result in severe acute portal hypertension. Staged restriction of CPSS flow by both surgical and complex transcatheter interventions has been successful in augmenting development of the IPVS such that complete occlusion of the CPSS can be performed. We report use of a modified microvascular plug to restrict CPSS flow with subsequent IPVS development and safe complete occlusion of CPSS.

Abstract
We report the case of a 27-year-old female patient with a history of cryptogenic cirrhosis who was admitted to the hospital due to multiple episodes of hematemesis secondary to bleeding esophageal varices. The varices were persistent and refractory to endoscopic intervention, so an emergent transjugular intrahepatic portosystemic shunt (TIPS) was performed by interventional radiology (IR). Months later, the patient returned to the hospital unresponsive with acute intermittent hepatic encephalopathy which required a TIPS reduction by IR. Once the TIPS reduction was performed, the patient’s hepatic encephalopathy declined, and her symptoms improved. Here, we present a unique method of TIPS reduction utilizing a single Viabahn VBX balloon-expandable stent (W. L. Gore & Associates, Inc; Flagstaff, AZ) to constrain the existing TIPS stent.

Abstract
The high technical success rate of transjugular intrahepatic portosystemic shunt (TIPS) placement makes the procedure a popular treatment option for symptomatic portal hypertension. Among the major drawbacks of the procedure - hepatic encephalopathy, acute hepatic failure, hemorrhage, biliary injury - TIPS dysfunction is one of the most prevalent, often requiring endovascular reintervention. Conventional techniques for shunt revision rely on transjugular access to the stent; but in technically difficult cases of abnormal angulation or severe stenosis, transhepatic access may also be required. The pull-through method utilizes both transjugular and transhepatic access to achieve stable through-and-through access in order to advance a sheath into the stent and recannulate the shunt. In the case of TIPS foreshortening, however, the distal end of the stent may abut the wall of the hepatic vein, jailing it off and obviating the advancement of a wire out of that end. We present here a case of a modified pull-through method for TIPS revision whereby a transhepatic wire is passed through the interstices of the stent at the distal end to enter into the hepatic vein and IVC. Subsequent snaring of the wire at the transjugular end establishes through-and-through access, and balloon dilation through the interstices allows for insertion of a transjugular sheath into the TIPS stent for recanalization. Our case highlights how the modified pull-through method, using trans-stent access, can be safely performed in patients with a foreshortened TIPS that abuts against the hepatic and portal vessel walls.

Abstract
AbstractTransjugular intrahepatic portosystemic shunt (TIPS) and spontaneous portosystemic shunts (SPSS) may lead to new or worsening hepatic encephalopathy (HE), especially in patients with chronic liver disease. Patients with medically refractory HE (rHE) may benefit from endovascular interventions. In this review, we briefly describe the post-TIPS and SPSS vascular anatomy, pathophysiology, classification, factors associated with HE, and the medical management of HE. In addition, we will discuss current endovascular techniques for HE management, their advantages, disadvantages, and review of the current literature.

Abstract
INTRODUCTION Balloon-occluded retrograde transvenous obliteration (BRTO) and transjugular intrahepatic portosystemic shunt (TIPS) are well-validated techniques in the management of portal hypertensive gastric variceal bleeding when medical management alone is not sufficient. However, despite their effectiveness, the adverse effects from both procedures make each technique more suitable to different cohorts of patient's depending on presence or lack of certain comorbidities. This study aims to compare clinical outcomes of patients who have undergone both procedures for portal hypertensive gastric variceal bleeding. MATERIALS AND METHODS We conducted a search of electronic databases from their establishment to April 2019. The goal was to compare the efficacy of BRTO and TIPS in preventing variceal rebleeding and the risk of adverse events such as ascites and hepatic encephalopathy. Predictors of overall survival and rebleeding were also analyzed. Meta-analysis was performed with STATA 15.1. RESULTS Five randomized controlled trials and retrospective cohort studies were included in our meta-analysis. The number of patients who underwent BRTO and TIPS were 308 and 127, respectively. BRTO and TIPS have similar technical success rates (91.4% vs. 89.7%, P=0.995) and immediate bleeding control rates (97.7% vs. 95.9%, P=0.836). However, compared with TIPS, BRTO has lower likelihood of future cumulative rebleeding (10.6% vs. 18.7%, P=0.027) and hepatic encephalopathy (0.00% vs. 23.1%, P<0.001) but is more likely to aggravate ascites (22.4% vs. 4.3%, P=0.009). Serum albumin level and presence of hepatocellular carcinoma are both independent predictors of increased likelihood of rebleeding and overall survival (P<0.001). CONCLUSIONS Both BRTO and TIPS are safe and effective interventions in the management algorithm of portal hypertensive gastric variceal bleeding. Although BRTO may be more effective at the prevention of future variceal rebleeding, the choice of BRTO versus TIPS should be tailored according to patient's comorbidities.

Abstract
Background and Aims Transjugular intrahepatic portosystemic shunt (TIPS) is used for decompressing clinically significant portal hypertension. The aims of this study were to evaluate clinical outcomes and adverse events associated with this procedure. Methods Retrospective single-center study including 78 patients submitted to TIPS placement between January 2015 and November 2018. Follow-up data were missing in 27 patients, and finally 51 patients were included in the study sample. Data collected from individual registries included demographics, comorbidities, laboratory results, complications, and clinical results according to the indication. Results Average pre-TIPS portosystemic pressure gradient decreased from 18.1 ± 5 to 6 ± 3 mm Hg after TIPS placement. Indications for TIPS were refractory ascites (63%, n = 49), recurrent or uncontrolled variceal bleeding (36%, n = 28), and Budd-Chiari syndrome (1.3%, n = 1). TIPS-related adverse events occurred in 29/51 (56.8%) patients, with hepatic encephalopathy (HE) in 21 (41%) patients, sepsis in 3, liver failure in 2, hemolytic anemia in 1, acute pulmonary edema in 1, and capsular perforation in 1 patient. Mean follow-up was 15.7 ± 15 months. First-month mortality was 11.7% (n = 6) (sepsis, n = 3; acute liver failure, n = 2; and recurrence of variceal bleeding, n = 1) and was significantly higher for patients with Child-Pugh >9 points (p = 0.01), model of end-stage liver disease (MELD) scores >19 (p = 0.02), and for patients with a history of HE before the procedure (p = 0.001). Older age (p = 0.006) and higher levels of creatinine (p = 0.008) were significantly higher in patients developing HE after TIPS. Ascites persisted in 21.2% (7/33 patients) and was more frequent in patients with lower baseline albumin levels (p = 0.003). Recurrent variceal bleeding occurred in 22% (n = 4/18 patients) and was more frequent in patients with lower baseline hemoglobin levels (p = 0.03). Conclusion TIPS is effective in up to 80% of patients presenting with variceal bleeding or refractory ascites. Careful patient selection based on age and HE history may reduce adverse events after TIPS.

Abstract
Hemorrhage, resulting from gastric varies, can be challenging to treat, given the various precipitating etiologies. A wide variety of treatment options exist for managing the diverse range of the underlying disease processes. While cirrhosis is the most common cause for gastric variceal bleeding, occlusion of the portal or splenic vein in noncirrhotic states results in a markedly different treatment paradigm. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Abstract
PURPOSE To report the results of transjugular intrahepatic portosystemic shunt (TIPS) reductions for hepatic encephalopathy (HE), acute liver failure (ALF), and pulmonary hypertension (PH). MATERIALS AND METHODS A single-institution retrospective review analysis was performed between 2007 and 2017 on patients undergoing TIPS reduction at single tertiary liver transplant center. A total of 27 patients (14 males and 13 females) underwent TIPS reduction for refractory HE (n = 18), ALF (n = 7), and PH (n = 2). The average age at time of reduction was 59 years (range, 23-73; standard deviation [SD], 8). Mean prereduction Model of End-State Liver Disease-Na and portosystemic pressure gradient were 19 (range, 11-29; SD, 6) and 9.4 mm Hg (range, -2 to 19; SD, 4.8), respectively. Comparison between responders and nonresponders was performed for multiple variables using a 2-tailed t test. Methods of reduction were compared in cases of HE. RESULTS Technical success, defined as a decrease of at least 50% of the caliber of the shunt, was 100%. Clinical success rates in improving HE, ALF, and PH were calculated at 89%, 71%, and 100%, respectively. Eight patients had major and 10 had minor complications after the reductions. There were 3 shunt thrombosis. Pre- and postreduction Model of End-State Liver Disease-Na, portosystemic pressure gradient change, duration of indwelling TIPS, and reduction method were not significantly different between responders and nonresponders. Six-month survival rates were 80%, 20%, and 100% for HE, ALF, and PH, respectively. CONCLUSIONS TIPS reduction is effective in reversing refractory HE, ALF, and PH after TIPS creation. TIPS reduction is associated with a high rate of complications and should be reserved for severe refractory overshunting complications.

Abstract
Within the broad spectrum of pediatric hepatobiliary disorders, hepatic vascular malformations, portal hypertension, and hepatic transplant interventions pose numerous challenges. The role of interventional radiology within each of these conditions is discussed herein, beginning with endovascular management of high flow hepatic vascular malformations. Next, while becoming less common in adult populations, surgical portoportal and portosystemic shunts remain prevalent in many pediatric centers. Shunt anatomy is reviewed along with endovascular management techniques for shunt dysfunction. Next, the growing experience with pediatric transjugular intrahepatic portosystemic shunt placement is reviewed along with tips for success in pediatric patients. Finally, pediatric hepatic transplant interventions are discussed with technical notes pertinent to split liver anatomy.

Abstract
Hepatic Encephalopathy (HE) is a neuropsychiatric syndrome that occurs in up to 30% of patients with cirrhosis. HE may be a consequence of pure liver failure, as in patients with fulminant hepatitis, or of the combination of liver failure and portal-systemic shunting, as in patients with liver cirrhosis. Several clinical and pathophysiologic observations suggest the importance of portal-systemic shunts in the development of HE. Episodes of HE are usually related to precipitating events, such as infections or gastrointestinal bleeding; a minority of cirrhotic patients experienced a chronic HE, refractory to standard medical treatment. This latter type of HE should be related to spontaneous or radiological (such as Transjugular Intrahepatic Portosystemic Shunt (TIPS)) portal systemic shunts, that could be restricted or occluded in patients with chronic HE. Both TIPS reduction and shunt occlusion are radiological procedures, safe and effective to ameliorate neurological symptoms in patients with refractory HE.

Abstract
A transjugular intrahepatic portosystemic shunt is the standard of care for complications of portal hypertension, such as variceal bleeding, refractory ascites, and hepatic hydrothorax. Hepatic encephalopathy, hepatic insufficiency, and right heart failure are the major complications after shunt creation. If medical management is unsuccessful, the interventionalist is consulted to close/revise the shunt. Closure of the shunt results in a dangerously abrupt increase in portal pressure, increasing risk for life-threatening variceal bleeding. Methods for revising these shunts are reported, which result in coarse adjustments in shunt diameter, causing rapid changes in portosystemic gradients. Our method for shunt revision utilizes carefully sized covered stents deployed in a controlled “onion skin” fashion to produce a narrowing within the hepatic venous limb of the shunt to precisely calibrate the desired portosystemic gradient.

Abstract
Recently, new techniques and devices in transjugular intrahepatic portosystemic shunt (TIPS) placement have emerged that can improve upon the standard procedure. Ultrasound guidance during TIPS with intracardiac echocardiography (ICE), placement of controlled expansion (CX) stents, and portal vein recanalization (PVR) via transsplenic access are three techniques with new data supporting their implementation. ICE guidance can improve the technical success of difficult cases, decrease procedure time, and decrease complications such as capsular puncture, hemobilia, and hepatic artery injury. CX stents offer the operator better control over the final portosystemic gradient, which is particularly useful in patients with a high risk of post-TIPS hepatic encephalopathy. Finally, transsplenic access provides a stable, antegrade route for PVR, which can be used to optimize transplant candidacy as well as treat the sequelae of portal hypertension in patients with portal vein thrombosis. This article will describe the benefits, technical parameters, and patient selection criteria for each of these new techniques.

Abstract
OBJECTIVES the aim of the study was to describe our 20-year experience with transjugular intrahepatic portosystemic shunt (TIPSS) procedures for children with resistant portal hypertension (PHTN). METHODS Retrospective review of all children that had a TIPSS performed at Birmingham Children's Hospital from January 1, 1995 to January 1, 2015. RESULTS Forty children underwent 42 attempted TIPSS for resistant PHTN with recurrent variceal bleeding (n = 35), refractory ascites (n = 4), and hypersplenism (n = 1). Median age at operation was 12 years (range 7 months-17 years). Thirty-four procedures were elective and 8 were emergency cases. TIPSS was established in 33 cases (79%). Median portal venous pressure reduction was 10 mmHg. Variceal bleeding ceased in 27 (96%) and ascites improved in all. Clinical improvement following TIPSS enabled 7 children to be bridged to transplantation and 7 others to become suitable for transplantation. The 1-year and 5-year survival with TIPSS was 57% and 35%, respectively. Child-Pugh score C was an independent risk factor for adverse outcome (Likelihood ratio (LR) = 8.0; 95% confidence interval (CI) 2.7 to 23.5; P = 0.001). There were 6 major complications: hepatic artery thrombosis and infarction (n = 1), hepatic artery pseudoaneurysm (n = 1), bile leak (n = 1), and hepatic encephalopathy (n = 3). Encephalopathy was resistant to medical treatment in 2 cases, necessitating staged closure in 1. Ten patients (30%) required intervention to maintain TIPSS patency. The 1-year and 5-year freedom from reintervention was 71% and 55%, respectively. CONCLUSIONS A TIPSS is highly successful in controlling symptoms in children with resistant PHTN and facilitating liver transplantation. It is technically demanding and not without risk. Patients must be appropriately selected and counselled.

Abstract
OBJECTIVE To report an initial experience using a primary constrained transjugular intrahepatic portosystemic shunt (TIPS) technique for treating cirrhotic patients with refractory ascites or variceal bleeding. METHODS All patients undergoing primary constrained (n = 9) and conventional (n = 18) TIPS between July 2014 and June 2016 were retrospectively reviewed. Preprocedure demographics, Child-Pugh, model for end-stage liver disease and technical variables were recorded. Outcomes measured included technical and clinical success, complications, 30-day mortality, as well as necessity for TIPS revision. Average (SD) and median follow-up was 237 (190) and 226 days. RESULTS All constrained and conventional TIPS were technically successful (100%). Clinical success as defined as a reduction or improvement in presenting symptoms was 88.9% (8/9) and 100% (18/18) in the constrained and conventional groups, respectively (p = 1). The average reduction in portosystemic gradient was lower in the constrained group, 6.1 mmHg compared with 10.6 mmHg in the conventional group (p = 0.73). The rate of hepatic encephalopathy following TIPS placement was higher in the conventional group [16.7% (3/18)] compared with 0% in the constrained group (p = 0.52). The percentage of patients requiring TIPS revision was lower in the constrained group, although the results were not significant (11.1 vs 22.2%, p = 0.63). CONCLUSION Primary constrained TIPS is a feasible modification to conventional TIPS with similar technical and clinical success rates. A trend towards a smaller reduction in the portosystemic gradient and need for revision was observed in the constrained group. Advances in knowledge: Primary constrained TIPS allows for greater stepwise control over shunt diameter and may represent an improved technique for patients at risk for hepatic encephalopathy.

Abstract
Bleeding from gastroesophageal varices is a serious complication in patients with liver cirrhosis and portal hypertension. Although there has been significance improvement in the prognosis of variceal bleeding with advancement in diagnostic and therapeutic modalities for its management, mortality rate still remains high. Therefore, appropriate prevention and rapid, effective management of bleeding from gastroesophageal varices is very important. Recently, various studies about management of gastoesophageal varices, including prevention of development and aggravation of varices, prevention of first variceal bleeding, management of acute variceal bleeding, and prevention of variceal rebleeding, have been published. The present article reviews published articles and practice guidelines to present the most optimal management of patients with gastroesophageal varices.

Abstract
Background To identify risk factors of stent graft thrombosis after transjugular intrahepatic portosystemic shunt (TIPS) creation. Methods Patients who underwent TIPS creation between June 2003 and January 2016 and with follow-up assessing stent graft patency were included (n=174). Baseline comorbidities, liver function, procedural details and follow-up liver function tests were analyzed in association with hazards of thrombosis on follow-up. Competing risk cox regression models were used considering liver transplant after TIPS creation as the competing risk variable. Results One-, 2- and 5-year primary patency rates were 94.1%, 91.7% and 78.2%, respectively. Patient age [sub-hazard ratio (sHR): 1.13; P=0.001], body mass index (BMI) <30 (sHR: 33.08; P=0.008) and a higher post-TIPS portosystemic pressure gradient (sHR: 1.14; P=0.023) were significantly associated with TIPS thrombosis in multivariate analysis. A higher rate of TIPS thrombosis was observed in those for whom the procedure was clinically unsuccessful (P=0.014). A significant increase in incidence of thrombosis was noted with increasing tertiles of post-TIPS portosystemic gradients (P value for trend=0.017). Conclusions Older age, lower BMI and higher post-TIPS portosystemic gradients were associated with higher hazards of shunt thrombosis after TIPS creation using stent grafts. Higher rates of shunt thrombosis were seen in patients for whom TIPS creation was clinically unsuccessful. The association between TIPS thrombosis and higher post-TIPS portosystemic gradients may indicate impaired flow through the shunt, a finding which may be technical or anatomic in nature and should be assessed before procedure completion.

Abstract
AIM To assess for passive expansion of sub-maximally dilated transjugular intrahepatic portosystemic shunts (TIPS) and compare outcomes with maximally dilated TIPS.
METHODS Polytetrafluoroethylene covered TIPS (Viatorr) from July 2002 to December 2013 were retrospectively reviewed at two hospitals in a single institution. Two hundred and thirty patients had TIPS maximally dilated to 10 mm (mTIPS), while 43 patients who were at increased risk for hepatic encephalopathy (HE), based on clinical evaluation or low pre-TIPS portosystemic gradient (PSG), had 10 mm TIPS sub-maximally dilated to 8 mm (smTIPS). Group characteristics (age, gender, Model for End-Stage Liver Disease score, post-TIPS PSG and clinical outcomes were compared between groups, including clinical success (ascites or varices), primary patency, primary assisted patency, and severe post-TIPS HE. A subset of fourteen patients with smTIPS underwent follow-up computed tomography imaging after TIPS creation, and were grouped based on time of imaging (< 6 mo and > 6 mo). Change in diameter and cross-sectional area were measured with 3D imaging software to evaluate for passive expansion.
RESULTS Patient characteristics were similar between the smTIPS and mTIPS groups, except for pre-TIPS portosystemic gradient, which was lower in the smTIPS group (19.4 mmHg ± 6.8 vs 22.4 mmHg ± 7.1, P = 0.01). Primary patency and primary assisted patency between smTIPS and mTIPS was not significantly different (P = 0.64 and 0.55, respectively). Four of the 55 patients (7%) with smTIPS required TIPS reduction for severe refractory HE, while this occurred in 6 of the 218 patients (3%) with mTIPS (P = 0.12). For the 14 patients with follow-up computed tomography (CT) imaging, the median imaging follow-up was 373 d. There was an increase in median TIPS diameter, median percent diameter change, median area, and median percent area change in patients with CT follow-up greater than 6 mo after TIPS placement compared to follow-up within 6 mo (8.45 mm, 5.58%, 56.04 mm2, and 11.48%, respectively, P = 0.01).
CONCLUSION Passive expansion of smTIPS does occur but clinical outcomes of smTIPS and mTIPS were similar. Sub-maximal dilation can prevent complications related to over-shunting in select patients.

Abstract
Extrahepatic portal vein obstruction (EHPVO) is a primary vascular condition characterized by chronic long standing blockage and cavernous transformation of portal vein with or without additional involvement of intrahepatic branches, splenic or superior mesenteric vein. Patients generally present in childhood with multiple episodes of variceal bleed and EHPVO is the predominant cause of paediatric portal hypertension (PHT) in developing countries. It is a pre-hepatic type of PHT in which liver functions and morphology are preserved till late. Characteristic imaging findings include multiple parabiliary venous collaterals which form to bypass the obstructed portal vein with resultant changes in biliary tree termed portal biliopathy or portal cavernoma cholangiopathy. Ultrasound with Doppler, computed tomography, magnetic resonance cholangiography and magnetic resonance portovenography are non-invasive techniques which can provide a comprehensive analysis of degree and extent of EHPVO, collaterals and bile duct abnormalities. These can also be used to assess in surgical planning as well screening for shunt patency in post-operative patients. The multitude of changes and complications seen in EHPVO can be addressed by various radiological interventional procedures. The myriad of symptoms arising secondary to vascular, biliary, visceral and neurocognitive changes in EHPVO can be managed by various radiological interventions like transjugular intra-hepatic portosystemic shunt, percutaneous transhepatic biliary drainage, partial splenic embolization, balloon occluded retrograde obliteration of portosystemic shunt (PSS) and revision of PSS.

Abstract
PURPOSE The goal of this study was to identify clinical and imaging variables that are associated with an unfavorable outcome during the 30 days following transjugular intrahepatic portosystemic shunt (TIPS) placement. MATERIAL AND METHODS Fifty-four consecutive patients with liver cirrhosis (Child-Pugh 6-13, Model for End-stage Liver Disease 7-26) underwent TIPS placement for refractory ascites (n=25), recurrent or uncontrolled variceal bleeding (n=23) or both (n=6). Clinical, biological and imaging variables including type of stent (covered n=40; bare-stent n=14), presence of spontaneous portosystemic shunt (n=31), and variations in portosystemic pressure gradient were recorded. Early severe complication was defined as the occurrence of overt hepatic encephalopathy or death within the 30days following TIPS placement. RESULTS Sixteen patients (30%) presented with early severe complication after TIPS placement. Child-Pugh score was independently associated with complication (HR=1.52, P<0.001). Among the imaging variables, opacification of spontaneous portosystemic shunt during TIPS placement but before its creation was associated with an increased risk of early complication (P=0.04). The other imaging variables were not associated with occurrence of complication. CONCLUSION Identification of spontaneous portosystemic shunt during TIPS placement reflects the presence of varices and is associated with an increased risk of early severe complication.

Abstract
Cirrhotic patients often develop severe complications requiring ICU admission. Grade III-IV hepatic encephalopathy, septic shock, acute-on-chronic liver failure and variceal bleeding are clinical decompensations that need a specific therapeutic approach in cirrhosis. The increased effectiveness of the treatments currently used in this setting and the spread of liver transplantation programs have substantially improved the prognosis of critically ill cirrhotic patients, which has facilitated their admission to critical care units. However, gastroenterologists and intensivists have limited knowledge of the pathogenesis, diagnosis and treatment of these complications and of the prognostic evaluation of critically ill cirrhotic patients. Cirrhotic patients present alterations in systemic and splanchnic hemodynamics, coagulation and immune dysfunction what further increase the complexity of the treatment, the risk of developing new complications and mortality in comparison with the general population. These differential characteristics have important diagnostic and therapeutic implications that must be known by general intensivists. In this context, the Catalan Society of Gastroenterology and Hepatology requested a group of experts to draft a position paper on the assessment and treatment of critically ill cirrhotic patients. This article describes the recommendations agreed upon at the consensus meetings and their main conclusions.

Abstract
Transjugular intrahepatic portosystemic shunt has evolved into an important option for management of complications of portal hypertension. The use of polytetrafluoroethylene covered stents enhances shunt patency. Hepatic encephalopathy (HE) remains a significant problem after TIPS placement. The approach to management of patients with refractory hepatic encephalopathy typically requires collaboration between different specialties. Patient selection for TIPS requires careful evaluation of risk factors for HE. TIPS procedure-related technical factors like stent size, attention to portosystemic pressure gradient reduction and use of adjunctive variceal embolization maybe important. Conservative medical therapy in combination with endovascular therapies often results in resolution or substantial reduction of symptoms. Liver transplantation is, however, the ultimate treatment.

Abstract
Hepatic encephalopathy (HE) is a neuropsychiatric syndrome which develops in patients with severe liver diseases and/or portal-systemic shunting. Minimal HE, the earliest manifestation of HE, has drawn increasing attention in the last decade. Minimal HE is associated with a series of brain functional changes, such as attention, working memory, and so on. Blood oxygen level dependent (BOLD) functional MRI (fMRI), especially resting-state fMRI has been used to explore the brain functional changes of HE, yielding important insights for understanding pathophysiological mechanisms and functional reorganization of HE. This paper briefly reviews the principles of BOLD fMRI, potential applications of resting-state fMRI with advanced post-processing algorithms such as regional homogeneity, amplitude of low frequency fluctuation, functional connectivity and future research perspective in this field.

Abstract
BACKGROUND AND AIM Transjugular intrahepatic portosystemic shunt (TIPS) is the mainstay treatment option for the complications of portal hypertension. Whether or not variceal embolization should be performed during TIPS procedures remains controversial. A meta-analysis to compare the incidence of shunt dysfunction, variceal rebleeding, encephalopathy, and death between patients treated with TIPS alone and those treated with TIPS combined with variceal embolization was conducted. METHODS All relevant studies were searched via PubMed, EMBASE, and Cochrane Library databases. Odds ratios (ORs) with 95% confidence intervals (CIs) were pooled. Heterogeneity among studies and publication bias were assessed. RESULTS Six articles were included in our study. Type of stents was covered (n = 2), bare (n = 2), mixed (n = 1), and unknown (n = 1). Varices were angiographically embolized by coils in six studies. Additional liquids agents were employed in three studies. Compared with TIPS alone group, TIPS combined with variceal embolization group had a significantly lower incidence of variceal rebleeding (OR 2.02, 95% CI 1.29-3.17, P = 0.002), but a similar incidence of shunt dysfunction (OR 1.26, 95% CI 0.76-2.08, P = 0.38), encephalopathy (OR 0.81, 95% CI 0.46-1.43, P = 0.47), and death (OR 0.90, 95% CI 0.55-1.47, P = 0.68). Neither any significant heterogeneity nor proof of publication bias among studies was found in all meta-analyses. CONCLUSIONS Adjunctive variceal embolization during TIPS procedures might be beneficial in the prevention of variceal rebleeding. However, given the heterogeneity of type of stents, embolic agents, type of varices, and indications of variceal embolization among studies, additional well-designed randomized, controlled trials with larger sample size and use of covered stents should be warranted to confirm these findings.

Abstract
Since Richter's description in the literature in 1989 of the first procedure on human patients, transjugular intrahepatic portosystemic shunt (TIPS) has been worldwide considered as a noninvasive technique to manage portal hypertension complications. TIPS succeeds in lowering the hepatic sinusoidal pressure and in increasing the circulatory flow, thus reducing sodium retention, ascites recurrence, and variceal bleeding. Required several revisions of the shunt TIPS can be performed in case of different conditions such as hepatorenal syndrome, hepatichydrothorax, portal vein thrombosis, and Budd-Chiari syndrome. Most of the previous studies on TIPS procedure were based on the use of bare stents and most patients chose TIPS 2-3 years after traditional treatment, thus making TIPS appear to be not superior to endoscopy in survival rates. Bare stents were associated with higher incidence of shunt failure and consequently patients required several revisions during the follow-up. With the introduction of a dedicated e-PTFE covered stent-graft, these problems were completely solved, No more reinterventions are required with a tremendous improvement of patient's quality of life. One of the main drawbacks of the use of e-PTFE covered stent-graft is higher incidence of hepatic encephalopathy. In those cases refractory to the conventional medical therapy, a shunt reduction must be performed.

Abstract
Computed tomography (CT) evaluation of the acute polytrauma patient has become well established as a mainstay of ER triage in hemodynamically stable patients. The radiologist plays a pivotal role in directing management by identifying and appropriately categorizing the severity of a patient's injuries. High-grade liver injuries have undergone an increasing trend of nonoperative management over the last several decades, with concurrent decrease in mortality. However, we present a case of a patient with a grade V liver laceration, in whom a rare portacaval shunt was also present. In the setting of this rare injury, the radiologist will likely be the first person to recognize and categorize a severe complication, which may indicate the need for a fundamental change in patient management.

Abstract
Hepatic encephalopathy (HE) is a broad spectrum of neuropsychiatric manifestations usually affecting individuals with end-stage liver disease. The presence of HE is a poor prognostic sign, with 1-year mortality rates of almost 60%. There is much debate about the underlying mechanisms that result in this syndrome; however, elevated plasma and central nervous system ammonia levels are considered key factors in its pathogenesis. Initial evaluation of the patient presenting with overt HE should include a careful search for predisposing factors, including underlying infection, gastrointestinal (GI) bleeding, electrolyte disturbances, hepatocellular carcinoma, dehydration, hypotension, and excessive use of benzodiazepines, psychoactive drugs, or alcohol. The mainstay of treatment for many years has been nonabsorbable disaccharides, particularly lactulose. Alternative treatments, which usually are second line in patients who do not respond to lactulose, include zinc, antibiotics (neomycin, metronidazole, and rifaximin), ornithine aspartate, sodium benzoate, probiotics, and surgical intervention. Accepted treatments for HE are associated with significant unpleasant side effects, including diarrhea, renal failure, neuropathy, and other GI disturbance. Newer therapies are still in development, and most are awaiting human trials in order to confirm their benefit. These include manganese chelators, L-carnitine, N-methyl-d-aspartate receptor antagonists, blood purification dialysis system, and an intravenous combination of sodium benzoate and phenylacetate.

Abstract
Patients with autogenous native vessel portosystemic shunts, whether surgical or congenital, may experience complications of excess shunt flow, including hepatopulmonary syndrome (HPS), hepatic encephalopathy (HE), and hepatic insufficiency. The authors explored endovascular reduction or occlusion of autogenous portosystemic shunts using methods commonly employed in transjugular intrahepatic portosystemic shunt (TIPS) reduction in four pediatric patients. Before treatment, the patients had hypoplastic, atrophic, or thrombosed portal veins. Following intervention, symptoms of overshunting resolved or improved in all patients without major complications. The innate plasticity of the pediatric portal venous system allowed for hypertrophy or development and maturation of cavernous transformations to accommodate increased hepatopetal blood flow and pressure.

Abstract
Despite the clinical complexity of patients with severe liver disease and the technical demands associated with the creation of a transjugular intrahepatic portosystemic shunt (TIPS), the major complication rate of this procedure is less than 5%. Delayed recognition and treatment of complications related to TIPS can have life-threatening consequences. This article provides an overview of the spectrum of periprocedural and delayed complications related to the performance of TIPS and offers the reader pearls for both avoiding and managing those complications.

Abstract
Insertion of a transjugular intrahepatic portosystemic shunt (TIPS) is an increasingly used treatment in the management of the complications of portal hypertension. However, one of the complications of this technique is refractory or recurrent hepatic encephalopathy, which poses a difficult clinical problem. We report the case of a patient who underwent TIPS insertion to control bleeding due to esophageal varices. The patient subsequently developed refractory hepatic encephalopathy, requiring reduction of the caliber of the shunt.

Abstract
Patients with end-stage liver disease awaiting liver transplantation frequently require intensive care admission and management due to either complications of liver failure or to intercurrent illness, particularly infection. Mortality in such patients is high and the development of an illness necessitating intensive care unit management can influence transplant candidacy. Specialized support frequently requires hemodynamic support, mechanical ventilation, and renal support. In this review, areas of management of particular importance to patients with end-stage liver disease in the intensive care unit are discussed. These areas are hepatic encephalopathy, infectious diseases, cardiovascular support, mechanical ventilation, renal support and combined transplantation, and decisions regarding delisting. Current knowledge specific to these patients, when available, is discussed, current practice is described, and areas of uncertainty in the evidence are discussed.

Management of refractory hepatic encephalopathy after insertion of TIPS: long-term results of shunt reduction with hourglass-shaped balloon-expandable stent-graft.

Abstract
OBJECTIVE The purpose of this study was to review the use of an hourglass-shaped expanded polytetrafluoroethylene (ePTFE) stent-graft to reduce transjugular intrahepatic portosystemic shunts in patients with hepatic encephalopathy refractory to conventional medical therapy. MATERIALS AND METHODS From January 2000 through December 2008, 189 transjugular intrahepatic portosystemic shunt procedures were performed with self-expanding stent-grafts. After a mean period of 43.4 +/- 57 weeks, hepatic encephalopathy developed in 12 patients and did not respond to conventional medical therapy with lactulose, nonabsorbable antibiotics, and a protein-restricted diet. In all cases, shunt reduction was performed with an hourglass-shaped balloon-expandable ePTFE stent-graft inserted into the original shunt. RESULTS Technically successful shunt reduction with an immediate increase in portosystemic gradient was achieved in all patients. Symptoms of hepatic encephalopathy disappeared a mean of 22.3 hours (range, 18-26 hours) after the procedure. After a mean follow-up period of 73.9 +/- 61.88 weeks, no recurrence of hepatic encephalopathy was found. One patient (8.3%) needed dilation of the hourglass-shaped stent-graft after 37 weeks because of recurrence of ascites. At the end of the study, five patients (41.6%) were alive in good clinical condition. Four patients (33.3%) died of cardiovascular failure 1, 2, 24, and 96 weeks after the corrective procedure. Eight months after the reduction procedure, one patient (8.3%) underwent orthotopic liver transplantation, which resulted in clinical improvement. Two patients (16.6%) were lost to follow-up 15.6 and 46.8 weeks after the procedure. CONCLUSION Shunt reduction with an hourglass-shaped ePTFE balloon-expandable stent-graft seems effective in reducing shunt flow and rapidly improving the patient's clinical condition. With this technique, shunt diameter can be modified on the basis of the patient's clinical condition.

Abstract
Significantly improved long-term patency can be achieved with transjugular intrahepatic portosystemic shunt (TIPS) endografts compared to conventional bare stents. In the USA, approximately 80% of TIPS procedures are performed using these devices. The phenomenon of early shunt thrombosis with TIPS created with bare stent TIPS, attributed to biliary fistulae, is seldom observed in patients with TIPS endografts. Intrashunt stenoses within the polytetrafluoroethylene-lined conduit are also rare. However, as with shunts created with bare stents, distinct patterns of dysfunction can occur with TIPS endografts. Some of these are inherent to the learning curve of placing these devices and others are secondary to device design. The interventional radiologist needs to be aware of these patterns of shunt dysfunction and have a systematic approach to their management.

Abstract
The creation of an intrahepatic portosystemic shunt via a transjugular approach (TIPS) is an interventional radiological procedure used to treat the complications of portal hypertension. TIPS insertion is principally indicated to prevent or arrest variceal bleeding when medical or endoscopic treatments fail, and in the management refractory ascites. This review discusses the development and execution of the technique, with focus on its clinical efficacy. Patient selection, imaging surveillance, revision techniques, and complications are also discussed.
