Abstract
Hepatorenal syndrome has conventionally been regarded as a multisystem syndrome in which pathophysiologic pathways that link cirrhosis with impairment in kidney function are followed by dysfunction of several organs such as the heart. The advances in cardiac studies have helped diagnose more subtle cardiac abnormalities that would have otherwise remained unnoticed in a significant subset of patients with advanced liver disease and cirrhosis. Accumulating data suggests that in many instances, the cardiac dysfunction precedes and predicts development of kidney disease in such patients. These observations point to the heart as a key player in hepatorenal syndrome and challenge the notion that the cardiac abnormalities are either the consequence of aberrancies in hepatorenal interactions or have only minor effects. As such, the disturbances traditionally bundled within hepatorenal syndrome may indeed represent a hepatic form of cardiorenal syndrome whereby the liver affects the kidney in part through cardiorenal pathways (that is, hepato-cardio-renal syndrome).

Abstract
In selected patients with cirrhosis and ascites, transjugular intrahepatic portosystemic shunt (TIPS) placement improves control of ascites and may reduce mortality. In this review, we summarize the current knowledge concerning the use of TIPS for the treatment of ascites in patients with cirrhosis, from pathophysiology of ascites formation to hemodynamic consequences, patient selection, and technical issues of TIPS insertion. The combination of these factors is important to guide clinical decision-making and identify the best strategy for each individual patient. There is still a need to identify the best timing for TIPS placement in the natural history of ascites (recurrent vs. refractory) as well as which type and level of renal dysfunction is acceptable when TIPS is proposed for the treatment of ascites in cirrhosis. Future studies are needed to define the optimal stent diameter according to patient characteristics and individual risk of shunt-related side effects, particularly hepatic encephalopathy and insufficient cardiac response to hemodynamic consequences of TIPS insertion.

Abstract
Background and Aims Transjugular intrahepatic portosystemic shunt (TIPS) allows a high blood volume into systemic circulation abruptly. The primary aim of the study was to investigate the effect of TIPS on systemic, portal hemodynamics, and electric cardiometry (EC) parameters in sedated and spontaneous breathing patients. Secondary aims?? Material and Methods Adult consecutive hepatic patients scheduled for elective TIPS were included. Patients were sedated with bispectral index-guided propofol infusion + fentanyl boluses. EC parameters, i.e., cardiac output (CO) and systemic vascular resistance (SVR) were noted. Noninvasive blood pressure, heart rate, central venous pressure (CVP, cmH2O), and portal venous pressure (PVP, cmH2O) were measured pre- and post-TIPS. Results Thirty-six people were enrolled (n = 25 included) from Aug 2018 to Dec 2019. Data (expressed in median (IQ)) were: age 33 (27-40) years, body mass index 24 (22.0-27) kg/m2, child A 60%, B 36%, and C 4%. Post-TIPS, PVP decreased (from 40 [37-45] to 34 [27-37] mmHg, P < 0.001), whereas CVP increased (from 7 [4-10] to 16 [10.0-19.0] mmHg, P < 0.001). The CO increased (P = 0.03) and SVR reduced (P = 0.012). Conclusion The reduction in PVP following successful TIPS insertion elevated the CVP abruptly. EC was able to monitor an immediate increase in the CO and a reduction in SVR in association with the above PVP and CVP changes. The results of this unique study indicate that EC monitoring is promising; however, further evaluation in a larger population and in correlation with other gold-standard CO monitors is still indicated.

Abstract
Hepatorenal syndrome (HRS) is one of the most severe complications in advanced cirrhosis. Type-1 HRS is relatively uncommon, yet carries considerably higher mortality rate. Effective treatment for HRS, especially therapy towards survival benefits, is still limited. However, the role for dialysis in HRS has been questioned over the years. The initiation of dialysis remains controversial for those who aren't transplant candidates. Meanwhile, there's a growing attention towards the successful use of peritoneal dialysis (PD) in cirrhotic patients. Herein, we report a case of HRS-1 in a 76-year-old male patient with decompensated cirrhosis. Through a series of adjustments of hemodialysis regimens and pharmacological prescriptions, patient stabilized and the opportunity for transjugular intrahepatic portosystemic shunt (TIPS) insertion was gained. PD was initiated after TIPS placement. With a gradual decrease of dialysis dose, patient successfully weaned off PD and achieved both reversal of HRS and kidney recovery. Markedly improved nutritional status and quality of life were reported. The potential role of dialysis and TIPS in HRS may be worth revisiting. Further studies regarding the optimal timing of dialysis initiation, choices of dialysis modality, and efficacy of dialysis therapy in combination with TIPS in HRS patients are warranted.

Abstract
Background: Heart failure (HF) is an uncommon complication after transjugular intrahepatic portosystemic shunt (TIPS) placement; its development represents a poor prognostic factor. Objective: To evaluate the frequency, risk factors, and association with survival of HF developing within 90 days after TIPS placement in patients with cirrhosis. Methods: This retrospective single-center study included patients with cirrhosis who underwent non-emergent covered-stent TIPS placement from June 2003 to December 2018, and who underwent echocardiogram within 2 months before TIPS placement and had at least 90 days of post-TIPS follow-up. Development of HF within 90 days after TIPS was recorded. Frequency of TIPS reduction for post-TIPS HF was determined. Univariable logistic regression analysis and ROC curve analysis were performed to assess potential risk factors for post-TIPS HF. Association of post-TIPS HF and 1-year survival was assessed by log rank test. Results: The study sample included 107 patients (median age, 58 years; 71/107 male, 36/107 female). Post-TIPS HF developed in 11/107 (10%) patients; median time to development of HF was 16 days (range, 2 - 62 days). Of these 11 patients, 3 (27%) required TIPS reduction to achieve resolution of HF symptoms after unsuccessful diuretic therapy. Pre-TIPS right atrium size [odds ratio (OR): 3.26 (95% CI: 1.22 - 10.16), p= .03], left ventricle end-systolic [OR: 5.43 (95% CI: 1.44 - 24.50), p= .02], and end-diastolic dimension [OR: 4.12 (95% CI: 1.51 - 13.47), p= .009], and pulmonary artery systolic pressure [OR: 1.27 (95% CI: 1.12 - 1.50), p= .001] were associated with post-TIPS HF. AUC of right atrium size, left ventricle systolic dimension, left ventricle diastolic dimension, and estimated peak pulmonary artery systolic pressure for development of post-TIPS HF were 0.71, 0.74, 0.72, and 0.83, respectively. At a cutoff of 31 mmHg, pulmonary artery systolic pressure achieved sensitivity of 70% and specificity of 86% for post-TIPS HF. Patients with and without post-TIPS HF had 1-year survival of 46% versus 73% (p= .06). Conclusion: Multiple Pre-TIPS echocardiographic variables predict development of post-TIPS HF in patients with cirrhosis. Clinical Impact: Preprocedural echocardiography may guide risk stratification in patients with cirrhosis being considered for TIPS placement.

Abstract
Transjugular intrahepatic portosystemic shunt (TIPS) is created between a hepatic vein (HV) and the portal vein (PV) to alleviate the symptoms of portal hypertension. Despite high procedural success rates, a myriad of complications may occur at every step of TIPS creation. These complications may be attributable to the procedure itself or the shunt. Portal vein puncture is the most challenging and rate-limiting step, with extrahepatic portal vein puncture being the most devastating tabletop complication. Hepatic encephalopathy is the most common shunt-related complication after TIPS. Unlike bare metallic stents, covered stents have a longer patency rate and lower incidence of TIPS dysfunction. Most of the TIPS dysfunction that occurs with stent-grafts is due to technical errors and mechanical factors. TIPS revision often requires a combination of angioplasty, mechanical thrombectomy, and thrombolytics with a need for additional stenting in some cases. This review article focuses on procedure and shunt-related complications, as well as preventive and management strategies.

Abstract
Ascites occurs in up to 70% of patients during the natural history of cirrhosis. Management of uncomplicated ascites includes sodium restriction and diuretic therapy, whereas that for refractory ascites (RA) is regular large-volume paracentesis with transjugular intrahepatic portosystemic shunt being offered in appropriate patients. Renal impairment occurs in up to 50% of patients with RA with type 1 hepatorenal syndrome (HRS) being most severe. Liver transplant remains the definitive treatment of eligible candidates with HRS, whereas combined liver and kidney transplant should be considered in patients requiring dialysis for more than 4 to 6 weeks or those with underlying chronic kidney disease.

Cost Effectiveness of Early Insertion of Transjugular Intrahepatic Portosystemic Shunts for Recurrent Ascites. Clin Gastroenterol Hepatol 2018; 16:1503-1510.e3.

Abstract
BACKGROUND & AIMS Treatment options for recurrent ascites resulting from decompensated cirrhosis include serial large-volume paracentesis and albumin infusion (LVP+A) or insertion of a transjugular intrahepatic portosystemic shunt (TIPS). Insertion of TIPSs with covered stents during early stages of ascites (early TIPS, defined as 2 LVPs within the past 3 weeks and <6 LVPs in the prior 3 months) significantly improves chances of survival and reduces complications of cirrhosis compared with LVP+A. However, it is not clear if TIPS insertion is cost effective in these patients. METHODS We developed a Markov model using the payer perspective for a hypothetical cohort of patients with cirrhosis with recurrent ascites receiving early TIPSs or LVP+A using data from publications and national databases collected from 2012 to 2018. Projected outcomes included quality-adjusted life-year (QALY), costs (2017 US dollars), and incremental cost-effectiveness ratios (ICERs; $/QALY). Sensitivity analyses (1-way, 2-way, and probabilistic) were conducted. ICERs less than $100,000 per QALY were considered cost effective. RESULTS In base-case analysis, early insertion of TIPS had a higher cost ($22,770) than LVP+A ($19,180), but also increased QALY (0.73 for early TIPSs and 0.65 for LVP+A), resulting in an ICER of $46,310/QALY. Results were sensitive to cost of uncomplicated TIPS insertion and transplant, need for LVP+A, probability of transplant, and decompensated QALY. In probabilistic sensitivity analysis, TIPS insertion was the optimal strategy in 59.1% of simulations. CONCLUSIONS Based on Markov model analysis, early placement of TIPSs appears to be a cost-effective strategy for management of specific patients with cirrhosis and recurrent ascites. TIPS placement should be considered early and as a first-line treatment option for select patients.

Abstract
BACKGROUND Portal hypertension (PHTN) increases the risk of non-hepatic surgery in cirrhotic patients. This first systematic review analyzes the place of transjugular intrahepatic portosystemic shunt (TIPS) in preparation for non-hepatic surgery in such patients. METHODS Medline, EMBASE, and Scopus databases were searched from 1990 to 2017 to identify reports on outcomes of non-hepatic surgery in cirrhotic patients with PHTN prepared by TIPS. Feasibility of TIPS and the planned surgery, and the short- and long-term outcomes of the latter were assessed. RESULTS Nineteen studies (64 patients) were selected. TIPS was indicated for past history of variceal bleeding and/or ascites in 22 (34%) and 33 (52%) patients, respectively. The planned surgery was gastrointestinal tract cancer in 38 (59%) patients, benign digestive or pelvic surgery in 21 (33%) patients and others in 4 (6%) patients. The TIPS procedure was successful in all, with a nil mortality rate. All patients could be operated within a median delay of 30 days from TIPS (mortality rate = 8%; overall morbidity rate = 59.4%). One year overall survival was 80%. CONCLUSIONS TIPS allows non-hepatic surgery in cirrhotic patients deemed non operable due to PHTN. Further evidence in larger cohort of patients is essential for wider applicability.

Abstract
PURPOSE To assess the incidence of symptomatic heart failure (SHF) occurring after transjugular intrahepatic portosystemic shunt (TIPS) placement, identify potential predictors of SHF, and evaluate clinical presentation and outcomes in cases of post-TIPS SHF. MATERIALS AND METHODS A prospectively maintained TIPS database was used to identify patients who underwent new TIPS placements at a large urban tertiary care center between 1995 and 2014. SHF was defined as otherwise unexplained new-onset dyspnea, hypoxemia, radiologic pulmonary edema, an increased need for diuretics, or need for intubation within 7 days after TIPS placement. Cases of deaths occurring within 7 days due to septic shock, continuing gastrointestinal bleed, or multi-organ failure were excluded. A control group consisting of a random sample of 40 patients from the same TIPS database was created. Uni-variable analysis was performed to assess differences between patients with and without post-TIPS SHF. RESULTS Of the 934 TIPS procedures performed during the study period, 883 met the inclusion criteria. Eight (0.9%) patients developed SHF, usually manifested by hypoxemia (50%) or dyspnea (25%) within 48 h. Patients with SHF had higher pre-TIPS right atrial (p = 0.03) and portal vein (p = 0.01) pressures, higher albumin (p = 0.02), and higher prothrombin time (p = 0.02). CONCLUSION Post-TIPS SHF is rare. Higher pre-TIPS right atrial and portal vein pressures are likely to predispose patients to this complication. Close monitoring may be warranted in these patients. In our eight patients, post-TIPS SHF did not result in poor outcomes.

Abstract
In the cirrhotic liver, distortion of the normal liver architecture is caused by structural and vascular changes. Portal hypertension is often associated with a hyperdynamic circulatory syndrome in which cardiac output and heart rate are increased and systemic vascular resistance is decreased. The release of several vasoactive substances is the primary factor involved in the reduction of mesenteric arterial resistance, resulting in sodium and water retention with eventual formation of ascites. Management of these patients with acute cardiac dysfunction often requires invasive hemodynamic monitoring in an intensive care unit setting to tailor decisions regarding use of fluids and vasopressors.

Abstract
BACKGROUND Transjugular intrahepatic portosystemic shunt (TIPSS) cause haemodynamic changes in patients with cirrhosis, yet little is known about long-term cardiopulmonary outcomes. AIM To evaluate the long-term cardiopulmonary outcome after TIPSS. METHODS We evaluated cardiopulmonary parameters including echocardiography during long-term follow-up after TIPSS. Results at 1-5 years after TIPSS were compared to those of cirrhotic controls. Pulmonary hypertension (PH) diagnoses rates were included. Endothelin 1, thromboxane B2 and serotonin were measured. RESULTS We found significant differences 1-5 years after TIPSS compared to pre-implantation values: median left atrial diameter (LAD) increased from 37 mm [interquartile range (IQR): 33-43] to 40 mm (IQR: 37-47, P = 0.001), left ventricular end-diastolic diameter (LV-EDD) increased from 45 mm (range: 41-49) to 48 mm (IQR: 45-52, P < 0.001), pulmonary artery systolic pressure (PASP) increased from 25 mmHg (IQR: 22-33) to 30 mmHg (IQR: 25-36, P = 0.038). Comparing results 1-5 years post-implantation to the comparison cohort revealed significantly higher (P < 0.05) LAD, LV-EDD and PASP values in TIPSS patients. PH prevalence was higher in the shunt group (4.43%) compared to controls (0.91%, P = 0.150). Thromboxane B2 levels correlated with PASP in the TIPSS cohort (P = 0.033). There was no transhepatic gradient observed for the vasoactive substances analysed. CONCLUSIONS TIPSS placement is accompanied by long-term cardiovascular changes, including cardiac volume overload, and is associated with an increased rate of pulmonary hypertension. The need for regular cardiac follow-up after TIPSS requires further evaluation.

[PMID: 27099653 PMCID: PMC4832094 DOI: 10.4254/wjh.v8.i11.520] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2015] [Revised: 01/21/2016] [Accepted: 03/16/2016] [Indexed: 02/06/2023] Open
Abstract
AIM: To investigate if echocardiographic and hemodynamic determinations obtained at the time of transjugular intrahepatic portosystemic shunt (TIPS) can provide prognostic information that will enhance risk stratification of patients.
METHODS: We reviewed medical records of 467 patients who underwent TIPS between July 2003 and December 2011 at our institution. We recorded information regarding patient demographics, underlying liver disease, indication for TIPS, baseline laboratory values, hemodynamic determinations at the time of TIPS, and echocardiographic measurements both before and after TIPS. We recorded patient comorbidities that may affect hemodynamic and echocardiographic determinations. We also calculated Model for End-stage Liver Disease (MELD) score and Child Turcotte Pugh (CTP) class. The following pre- and post-TIPS echocardiographic determinations were recorded: Left ventricular ejection fraction, right ventricular (RV) systolic pressure, subjective RV dilation, and subjective RV function. We recorded the following hemodynamic measurements: Right atrial (RA) pressure before and after TIPS, inferior vena cava pressure before and after TIPS, free hepatic vein pressure, portal vein pressure before and after TIPS, and hepatic venous pressure gradient (HVPG).
RESULTS: We reviewed 418 patients with portal hypertension undergoing TIPS. RA pressure increased by a mean ± SD of 4.8 ± 3.9 mmHg (P < 0.001), HVPG decreased by 6.8 ± 3.5 mmHg (P < 0.001). In multivariate linear regression analysis, a higher MELD score, lower platelet count, splenectomy and a higher portal vein pressure were independent predictors of higher RA pressure (R = 0.55). Three variables predicted 3-mo mortality after TIPS in a multivariate analysis: Age, MELD score, and CTP grade C. Change in the RA pressure after TIPS predicted long-term mortality (per 1 mmHg change, HR = 1.03, 95%CI: 1.01-1.06, P < 0.012).
CONCLUSION: RA pressure increased immediately after TIPS particularly in patients with worse liver function, portal hypertension, emergent TIPS placement and history of splenectomy. The increase in RA pressure after TIPS was associated with increased mortality. Age, splenectomy, MELD score and CTP grade were independent predictors of long-term mortality after TIPS.

Abstract
OBJECTIVES The purpose of this study was to investigate the relationships between the splenorenal shunt (SRS)/portal vein (PV) diameter ratio (SRS/PV ratio) and systemic hemodynamics in patients with liver cirrhosis. PATIENTS AND METHODS Thirty-seven patients with SRS due to liver cirrhosis were included in this study. SRS was evaluated in the retropancreatic space on contrast-enhanced CT and the diameter was measured at the maximum point. Systemic hemodynamics was studied using a thermodilution catheter. RESULTS The SRS/PV ratio showed a significant correlation with the cardiac index (p < 0.01), and showed an inverse correlation with the systemic vascular resistance index and the arteriovenous oxygen content difference [C(a-v)O2] (p < 0.01). The Child-Pugh score showed a correlation with the SRS/PV ratio (p < 0.01). The SRS/PV ratio was 0.89 ± 0.52, 1.02 ± 0.51, and 1.74 ± 0.50 in the Child-Pugh A, B, and C classes, respectively. The SRS/PV ratio in the Child-Pugh C class was significantly higher than those in classes A and B (p < 0.01). The plasma ammonia level was 75.3 ± 23.2 in the group with an SRS/PV ratio <1.0 (n = 19) versus 102.6 ± 34.8 in the group with an SRS/PV ratio ≥1.0 (n = 18), and the ratio of encephalopathy was 5% (1/19) in the group with an SRS/PV ratio <1.0 (n = 19) versus 50% (9/18) in the group with an SRS/PV ratio ≥1.0 (n = 18), respectively. The differences between the two groups were statistically significant (p < 0.01). CONCLUSIONS We conclude that the increase in the SRS/PV ratio is accompanied by deteriorated liver function, hyperdynamic status, and narrowed C(a-v)O2.

Abstract
Cirrhosis results from progressive fibrosis and is the final outcome of all chronic liver disease. It is among the ten leading causes of death in United States. Cirrhosis can result in portal hypertension and/or hepatic dysfunction. Both of these either alone or in combination can lead to many complications, including ascites, varices, hepatic encephalopathy, hepatocellular carcinoma, hepatopulmonary syndrome, and coagulation disorders. Cirrhosis and its complications not only impair quality of life but also decrease survival. Managing patients with cirrhosis can be a challenge and requires an organized and systematic approach. Increasing physicians’ knowledge about prevention and treatment of these potential complications is important to improve patient outcomes. A literature search of the published data was performed to provide a comprehensive review regarding the management of cirrhosis and its complications.

Abstract
In the 25 years since the first TIPS intervention has been performed, technical standards, indications, and contraindications have been set up. The previous considerable problem of shunt failure by thrombosis or intimal proliferation in the stent or in the draining hepatic vein has been reduced considerably by the availability of polytetrafluoroethylene (PTFE)-covered stents resulting in reduced rebleeding and improved survival. Unfortunately, most clinical studies have been performed prior to the release of the covered stent and, therefore, do not represent the present state of the art. In spite of this, TIPS has gained increasing acceptance in the treatment of the various complications of portal hypertension and vascular diseases of the liver.

Abstract
BACKGROUND & AIMS Transjugular intrahepatic stent-shunt (TIPSS) insertion, in patients with uncontrolled gastro-intestinal bleeding, often results in worsening of the systemic hemodynamics which can be associated with intracranial hypertension but the underlying mechanisms are unclear. This study explored the hypothesis that TIPSS insertion results in acute endotoxemia which is associated with increased nitric oxide production resulting in systemic and cerebral vasodilatation. METHODS Twelve patients with cirrhosis who were undergoing TIPSS for uncontrolled variceal bleeding were studied prior to and 1-h after TIPSS insertion. Changes in cardiac output (CO) and cerebral blood flow (CBF) were measured. NO production was measured using stable isotopes using l-[guanidino-(15)N(2)] arginine and l-[ureido-(13)C;5,5-(2)H(2)] citrulline infusion. The effect of pre- and post-TIPSS plasma on nitric oxide synthase (NOS) activity on human endothelial cell-line (HUVEC) was measured. RESULTS TIPSS insertion resulted in a significant increase in CO and CBF. Endotoxin and induced neutrophil oxidative burst increased significantly without any significant changes in cytokines. Whole body NO production increased significantly and this was associated with increased iNOS activity in the HUVEC lines. The change in NO production correlated with the changes in CO and CBF. Brain flux of ammonia increased without significant changes in arterial ammonia. CONCLUSIONS In conclusion, the insertion of TIPSS results in acute endotoxemia which is associated with increased nitric oxide production possibly through an iNOS dependent mechanism which may have important pathophysiological and therapeutic relevance to understanding the basis of circulatory failure in the critically ill cirrhotic patient.

Abstract
Patients suffering from severe chronic liver disease, in particular cirrhosis, are at risk for pulmonary complications. The leading clinical symptom is shortness of breath, which can accompany the actual disease as indirect effect because of anemia, faint muscles or ascites. On the other hand, dyspnea can have multiple additive causes in case of accompanying cardial or pulmonary disease. The hepatopulmonary syndrome (HPS) and the portopulmonary hypertension (PoPH) belong to the most relevant pulmonary complications in liver cirrhosis. HPS appears to be more common than PoPH and the presence of either entity increases morbidity and mortality in patients with liver disease. The two diseases have to be strictly distinguished, as they have opposed histological and pathophysiological origin. While the HPS is a dilatative pulmonary- vascular disease, the PoPH is a constrictive or obliterative pulmonary-vascular disease in the context of a liver disease or a portal hypertension. Therefore, these diseases are separate entities also when it comes to diagnostics and therapy.

Abstract
Ascites, hepatic encephalopathy and variceal hemorrhage are three major complications of portal hypertension. The diagnostic evaluation of ascites involves an assessment of its etiology by determining the serum-ascites albumin gradient and the exclusion of spontaneous bacterial peritonitis. Ascites is primarily related to an inability to excrete an adequate amount of sodium into urine, leading to a positive sodium balance. Sodium restriction and diuretic therapy are keys of ascites control. But, with the case of refractory ascites, large volume paracentesis and transjugular portosystemic shunts are required. In hepatorenal syndrome, splanchnic vasodilatation with reduction in effective arterial volume causes intense renal vasoconstriction. Splanchnic and/or peripheral vasoconstrictors with albumin infusion, and renal replacement therapy are only bridging therapy. Liver transplantation is the only definitive modality of improving the long term prognosis.

Abstract
The purpose of this study was to assess shortterm effects of transjugular intrahepatic shunt (TIPS) on cardiac function with cardiac magnetic resonance imaging (MRI) in patients with liver cirrhosis. Eleven patients (six males and five females) with intractable esophageal varices or refractory ascites were imaged with MRI at 1.5 T prior to, within 24 h after, and 4-6 months after TIPS creation (n = 5). Invasive pressures were registered during TIPS creation. MRI consisted of a stack of contiguous slices as well as phase contrast images at all four valve planes and perpendicular to the portal vein. Imaging data were analyzed through time-volume curves and first derivatives. The portoatrial pressure gradient decreased from 19.8 + or = 2.3 to 6.6 + or = 2.3, accompanied by a nearly two fold increase in central pressures and pulmonary capillary wedge pressure immediately after TIPS creation. Left and right end diastolic volumes and stroke volumes increased by 11, 13, and 24%, respectively (p\0.001), but dropped back to baseline at follow-up. End systolic volumes remained unchanged. E/A ratios remained within normal range. During follow-up the left ventricular mass was larger than baseline values in all patients, with an average increase of 7.9 g (p\0.001). In conclusion, the increased volume load shunted to the heart after TIPS creation transiently exceeded the preload reserve of the right and left ventricle, leading to significantly increased pulmonary wedge pressures and persistent enlargement of the left and right atria. Normalization of cardiac dimensions was observed after months together with mild left ventricular hypertrophy.

Abstract
Increased cardiac output was first described in patients with cirrhosis more than fifty years ago. Later, various observations have indicated the presence of a latent cardiac dysfunction, which includes a combination of reduced cardiac contractility with systolic and diastolic dysfunction and electrophysiological abnormalities. This syndrome is termed cirrhotic cardiomyopathy. Results of experimental studies indicate the involvement of several mechanisms in the pathophysiology, such as reduced beta-adrenergic receptor signal transduction, altered transmembrane currents and electromechanical coupling, nitric oxide overproduction, and cannabinoid receptor activation. Systolic incompetence in patients can be revealed by pharmacological or physical strain and during stressful procedures, such as transjugular intrahepatic portosystemic shunt insertion and liver transplantation. Systolic dysfunction has recently been implicated in development of renal failure in advanced disease. Diastolic dysfunction reflects delayed left ventricular filling and is partly attributed to ventricular hypertrophy, subendocardial oedema, and altered collagen structure. The QT interval is prolonged in about half of the cirrhotic patients and it may be normalised by beta-blockers. No specific therapy for cirrhotic cardiomyopathy can be recommended, but treatment should be supportive and directed against the cardiac dysfunction. Future research should better describe the prevalence, impact on morbidity and survival, and look for potential treatments.

Abstract
Portopulmonary hypertension (PoPH) is an underrecognized complication of portal hypertension, related to cirrhosis and noncirrhotic portal hypertension. PoPH has been found in 5-6% of patients with decompensated liver disease and may adversely affect outcome after liver transplantation. The prevalence of PoPH is unrelated to the severity of liver disease but associated with female sex and underlying autoimmune liver disease. Diagnosis of PoPH is based on screening with Doppler echocardiography and confirmation by right-heart catheterization. Treatment options with proven efficacy in idiopathic pulmonary hypertension include endothelin receptor antagonists, prostanoids, and sildenafil. In PoPH, such targeted treatment was found to be safe in small uncontrolled studies but randomized trials demonstrating its benefit are lacking.

Abstract
OBJECTIVES The clinical significance of diastolic dysfunction in cirrhosis, a feature of cirrhotic cardiomyopathy, is unclear. The aim of this study was to assess the utility of E/A ratio, an indicator of diastolic dysfunction, to predict ascites clearance and mortality after transjugular intrahepatic portosystemic stent shunt (TIPS) insertion. METHODS A total of 101 cirrhotic patients who received TIPS had pre-TIPS assessments of demographics, severity of liver dysfunction (Child-Pugh and Model for End-Stage Liver Disease (MELD) scores), renal function, hemodynamics, and cardiac function (two-dimensional echocardiography). An E/A ratio of < or =1 was used to indicate diastolic dysfunction. Patients were followed-up for a mean period of 24.6+/-2.4 months post TIPS. RESULTS A total of 41 patients with an E/A ratio of < or =1 (group A), and 60 patients with an E/A ratio of >1 (group B) were studied. Group A had significantly higher MELD scores (14.0+/-1.0 vs. 11.4+/-0.8; P=0.03), because of higher serum creatinine levels (107+/-5 vs. 86+/-6 micromol/l; P<0.01). There was no difference in pre-TIPS systemic hemodynamics, systolic function, or portal pressure between the two groups. After TIPS, more patients in group B had ascites clearance (log rank, P=0.038), and the same patients had a higher probability of survival (log rank, P=0.046). There were three post-TIPS cardiac deaths in group A only. A multivariate analysis showed that an E/A of ratio < or =1 was predictive of slow ascites clearance (hazard ratio=7.3, 95% confidence interval=1.3-40.7, P=0.021) and death after TIPS (hazard ratio=4.7, 95% confidence interval=1.1-20.2, P=0.035). CONCLUSIONS Diastolic dysfunction, indicated by reduced E/A ratio, is prevalent in advanced cirrhosis and is associated with reduced ascites clearance and increased mortality post TIPS, possibly related to worsening of hemodynamic dysfunction in the post-TIPS period.

Abstract
BACKGROUND This study was undertaken to prospectively evaluate the impact of partial portal decompression on renal haemodynamics and renal function in patients with cirrhosis and portal hypertension. METHODS Fifteen consecutive patients (median age 49 years) with cirrhosis underwent partial portal decompression through portacaval shunting or transjugular intrahepatic portosystemic shunting (TIPS). Cirrhosis was caused by alcohol in 47%, hepatitis C in 13%, both in 33% and autoimmune factors in 7% of patients. Child class was A in 13%, B in 20% and C in 67% of patients. The median score on the Model for End-stage Liver Disease (MELD) was 14.0 (mean 15.0 +/- 7.7). Serum creatinine (SrCr) and creatinine clearance (CrCl) were determined pre-shunt, 5 days after shunting and 1 year after shunting. Colour-flow Doppler ultrasound of the renal arteries was also undertaken with calculation of the resistive index (RI) and pulsatility index (PI). Changes in the portal vein-inferior vena cava pressure gradient with shunting were determined. RESULTS With shunting, the portal vein-inferior vena cava gradients dropped significantly, with significant increases in PI in the early period after shunting. Creatinine clearance improved in the early post-shunt period. However, SrCr levels did not significantly improve. At 1 year after shunting, both CrCl and SrCr levels tended towards pre-shunt levels and the increase in PI did not persist. DISCUSSION Partial portal decompression improves mild to moderate renal dysfunction in patients with cirrhosis. Early improvements in renal function after shunting begin to disappear by 1 year after shunting.

Abstract
Cardiac failure affects the liver and liver dysfunction affects the heart. Chronic and acute heart failure can lead to cardiac cirrhosis and cardiogenic ischemic hepatitis. These conditions may impair liver function and treatment should be directed towards the primary heart disease and seek to secure perfusion of vital organs. In patients with advanced cirrhosis, physical and/or pharmacological stress may reveal a reduced cardiac performance with systolic and diastolic dysfunction and electrophysical abnormalities, termed cirrhotic cardiomyopathy. Pathophysiological mechanisms include reduced beta-adrenergic receptor signal transduction and defective cardiac electromechanical coupling. However, the QT interval is prolonged in approximately half of patients with cirrhosis and it may be improved by beta-blockers. No specific therapy can be recommended but it should be supportive and directed against the heart failure. Transjugular intrahepatic portosystemic shunt insertion and liver transplantation affect cardiac function in portal hypertensive patients and cause stress to the cirrhotic heart, with a risk of perioperative heart failure. The risk and prevalence of coronary artery disease are increasing in cirrhotic patients and since perioperative mortality is high, careful evaluation of such patients with dobutamine stress echocardiography, coronary angiography and myocardial perfusion imaging is required prior to liver transplantation. Future research should focus on beneficial effects of treatment on cardiac function and mortality.

Transjugular intrahepatic portosystemic shunts in hemodialysis-dependent patients and patients with advanced renal insufficiency: safety, caution, and encephalopathy. J Vasc Interv Radiol 2008; 19:516-20. [PMID: 18375295 DOI: 10.1016/j.jvir.2007.11.011] [Citation(s) in RCA: 15] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2007] [Revised: 11/11/2007] [Accepted: 11/15/2007] [Indexed: 01/31/2023] Open
Abstract
PURPOSE To retrospectively determine the acute safety and chronic outcomes of transjugular intrahepatic portosystemic shunt (TIPS) creation in patients with hemodialysis-dependent end-stage renal disease for control of bleeding and refractory ascites. MATERIALS AND METHODS Four dialysis-dependent patients and one renal transplant recipient (glomerular filtration rate, 27 mL/min) underwent TIPS creation for treatment of refractory ascites (n = 3) and recurrent portal hypertensive bleeding (n = 1). A sixth patient developed unrelated renal failure 3 years after initial TIPS formation and presented with encephalopathy at that time. All had nearly normal liver function test results and no previous baseline encephalopathy. Three dialysis recipients underwent dialysis immediately after the TIPS procedure in an intensive care unit; one did not. RESULTS There were no complications of fluid overload or pulmonary edema after TIPS creation in the patients who immediately underwent dialysis. The one patient in whom dialysis was delayed developed respiratory failure and shock liver (ie, ischemic hepatitis). Ascites resolved in all three patients, and no recurrent variceal bleeding occurred during a mean follow-up of 17 months. Severe, grade 2-4 hepatic encephalopathy developed in all patients; in one patient, its onset was delayed until the onset of renal failure 3 years after the original TIPS procedure. Shunt reduction was required in four cases and competitive variceal embolization was required in one to reduce portosystemic diversion. No less than grade 1 episodic baseline encephalopathy was present in all patients despite continued use of the maximum prescribed medical therapy thereafter. CONCLUSIONS TIPS creation is effective in controlling ascites and bleeding in functionally anephric patients, but at the cost of marked and disproportionate hepatic encephalopathy. Prompt, acute postprocedural dialysis and fluid management is critical for safe creation of a TIPS in dialysis-dependent patients.

Abstract
BACKGROUND & AIMS It has been proposed that activation of the sympathetic nervous system causes a rightward shift in the renal autoregulatory curve such that renal blood flow is critically dependent on renal perfusion pressure and that this contributes to the development of the hepatorenal syndrome. The aims of the study were to determine the relationship of renal blood flow and renal perfusion pressure in patients with liver cirrhosis and the effect on renal hemodynamics following insertion of a transjugular intrahepatic portosystemic shunt (TIPS). METHODS Fifty-six patients were recruited into groups (1) with no ascites, (2) with diuretic-responsive ascites, (3) with intractable ascites, (4) with type II hepatorenal syndrome, and (5) requiring a TIPSs for refractory ascites. We measured cardiac hemodynamics, renal blood flow, renal perfusion pressure, and portal pressure and norepinephrine levels and mathematically modeled the renal autoregulatory curve. RESULTS Renal blood flow correlated with renal perfusion pressure (r(2) = 0.78; P < .001) and inversely with the hepatic venous pressure gradient (r(2) = 0.61; P < .0001) and plasma norepinephrine levels (r(2) = 0.78; P < .0001). Norepinephrine levels increased with increasing disease severity, and this was associated with a rightward and downward shift of the renal blood flow/renal perfusion pressure autoregulatory curve. TIPS insertion reduced portal pressure and plasma norepinephrine levels (P < .001), and the renal blood flow/renal perfusion pressure curve was shifted upward. CONCLUSIONS The relationship between renal blood flow and renal perfusion pressure involves a critical interplay between the sympathetic nervous system and the kidney. TIPS insertion decreases sympathetic activation and improves renal function through positive effects on renal blood flow autoregulation.

Abstract
Transjugular intrahepatic portosystemic shunt (TIPS) is an interventional radiology technique that has shown a 90% success rate to decompress the portal circulation. As a non-surgical intervention, without requirement for anesthesia and very low procedure-related mortality, TIPS is applicable to severe cirrhotic patients, who are otherwise untreatable, for example, nonsurgical candidates. TIPS constitutes the most frequently employed tool to achieve portosystemic shunting. TIPS acts by lowering portal pressure, which is the main underlying pathophysiologic determinant of the major complications of cirrhosis. Regarding esophagogastric variceal bleeding, TIPS has excellent hemostatic effect (95%) with low rebleeding rate (<20%). TIPS is an accepted rescue therapy for first line treatment failures in 2 settings (1) acute variceal bleeding and (2) secondary prophylaxis. In addition, TIPS offers 70% to 90% hemostasis to patients presenting with recurrent active variceal bleeding. TIPS is more effective than standard therapy for patients with hepatic venous pressure gradient >20mm Hg. TIPS is particularly useful to treat bleeding from varices inaccessible to endoscopy. TIPS should not be applied for primary prophylaxis of variceal bleeding. Portosystemic encephalopathy and stent dysfunction are TIPS major drawbacks. The weakness of the TIPS procedure is the frequent need for endovascular reintervention to ensure stent patency. The circulatory effects of TIPS are an attractive approach for the treatment of refractory ascites and hepatorenal syndrome, yet TIPS is not considered first line therapy for refractory ascites owing to unacceptable incidence of portosystemic encephalopathy. Pre-TIPS evaluation taking into account predictors of outcome is mandatory. The improved results achieved with covered-stents might expand the currently accepted recommendations for TIPS use.

Abstract
INTRODUCTION Porto-pulmonary hypertension (PoPH) is the association of pulmonary artery hypertension and portal hypertension. The diagnosis of PoPH is based on pulmonary haemodynamic criteria, obtained via right heart catheterisation, including an increase in mean pulmonary arterial pressure (> 25 mmHg) and in pulmonary vascular resistance (> 240 dyn.s.cm-5). STATE OF THE ART The exact pathophysiological mechanisms of PoPH are unknown. However, since PoPH has been reported in patients with non-hepatic portal hypertension, the factor that determines the development must be portal hypertension rather than liver disease per se. Moreover, no simple relationship has been identified between the degree of hepatic impairment and the severity of PoPH. The clinical presentation is non-specific with haemodynamic failure occurring at the end stage. As a consequence, screening by annual transthoracic echocardiography is highly recommended in potential liver transplant candidates. Therapy with prostacyclin analogues may partially relieve pulmonary arterial hypertension (PAH). Liver transplantation has an uncertain effect in PoPH and because PoPH is associated with a high perioperative mortality, moderate to severe PoPH remains a contraindication for liver transplantation. PERSPECTIVES AND CONCLUSIONS Recent advances in the management of PoPH have improved the prognosis. The safety and efficacy of oral endothelin receptor antagonists and oral phosphodiesterase inhibitors is currently under evaluation. A therapeutic approach utilising combinations of drugs should provide better long-term results.

Abstract
Ascites is the most common complication of liver cirrhosis and when it develops mortality is 50% at 5 years, apart from liver transplantation. Large volume paracentesis has been the only option for ascites refractory to medical treatment. The role of transjugular intrahepatic portosystemic shunt in the management of diuretic-resistant ascites has been evaluated in many cohort studies and five randomized trials up to now, clearly showing improvement in natriuresis and clinical efficacy. It, however, remains unclear how transjugular intrahepatic portosystemic shunt affects survival and quality of life, because hospital admissions owing to worsening encephalopathy may counterbalance the reduced need of paracentesis. What is clear is that the patient selection is critical. About 30% of patients with ascites develop hepatorenal syndrome at 5 years, leading to high mortality in its severe and progressive form. As its main pathogenetic factor is derangement of circulatory function owing to portal hypertension, these patients may benefit from transjugular intrahepatic portosystemic shunt, but this has been shown only in small series, in which mortality remains very high, owing to the underlying poor liver function.

Abstract
Portopulmonary hypertension (PPHT) is defined as precapillary pulmonary hypertension accompanied by hepatic disease or portal hypertension. Pulmonary hypertension results from excessive pulmonary vascular remodeling and vasoconstriction. These histological alterations have been indistinguishable from those of other forms of pulmonary arterial hypertension. Factors involved in the pathogenesis of PPHT include volume overload, hyperdynamic circulation, and circulating vasoactive mediators. The disorder has a substantial impact on survival and requires focused treatment. Liver transplantation in patients with moderate to severe PPHT is associated with a significantly reduced survival rate. The best medical treatment for patients with PPHT is controversial; most authors currently regard continuous intravenous application of prostacyclin as the treatment of choice for patients with severe PPHT. There is only very limited reported experience with inhaled prostacyclin or its analog, iloprost. Increasing evidence of the efficacy of the endothelin-receptor antagonist bosentan and of the phosphodiesterase-5 inhibitor sildenafil is emerging in highly selected patients with PPHT. In the future, a combination therapy of the above-mentioned agents might become a therapeutic option. Other agents such as beta-blockers seem to be harmful to patients with moderate to severe portopulmonary hypertension. Up-to-date, randomized, double-blind, controlled clinical trials are lacking and are needed urgently.

Abstract
Liver cirrhosis is associated with several cardiovascular disturbances. These disturbances include hyperdynamic systemic circulation, manifested by an increased cardiac output and decreased peripheral vascular resistance and arterial pressure. Despite the baseline increase in cardiac output, cardiac function in patients with cirrhosis is abnormal in several respects. Patients show attenuated systolic and diastolic contractile responses to stress stimuli, electrophysiological repolarization changes, including prolonged QT interval, and enlargement or hypertrophy of cardiac chambers. This constellation of cardiac abnormalities is termed cirrhotic cardiomyopathy. It has been suggested that cirrhotic cardiomyopathy has a role in the pathogenesis of cardiac dysfunction and even overt heart failure after transjugular intrahepatic portosystemic shunt placement, major surgery and liver transplantation. Cardiac dysfunction contributes to morbidity and mortality after liver transplantation, even in many patients who have no prior history of cardiac disease. Depressed cardiac contractility contributes to the pathogenesis of hepatorenal syndrome, especially in patients with spontaneous bacterial peritonitis. Pathogenic mechanisms underlying cirrhotic cardiomyopathy include cardiomyocyte-membrane biophysical changes, attenuation of the stimulatory beta-adrenergic system and overactivity of negative inotropic systems mediated via cyclic GMP. The clinical features, general diagnostic criteria, pathogenesis and treatment of cirrhotic cardiomyopathy are discussed in this review.

Abstract
The kidney plays an important role in ammonia metabolism. In this study the hypothesis was tested that the kidney can acutely diminish ammonia release after portacaval shunting. Thirteen patients with cirrhosis (6 female/7 male, age 54.4 +/- 3.3 yr) were studied. Blood was sampled prior to and 1 h after transjugular intrahepatic stent-shunt (TIPSS) insertion from the portal vein, a hepatic vein, the right renal vein, and the femoral vein, and renal and liver plasma flow were measured. Prior to TIPSS, renal ammonia release was significantly higher than ammonia release from the splanchnic region, which was not significantly different from zero. TIPSS insertion did not change arterial ammonia concentration or ammonia release from the splanchnic region but reduced renal ammonia release into the circulation (P < 0.05) to values that were not different from zero. TIPSS resulted in a tendency toward increased venous-arterial ammonia concentration differences across leg muscle. Post-TIPSS ammonia efflux via portasystemic shunts was estimated to be seven times higher than renal efflux. Kidneys have the ability to acutely diminish systemic ammonia release after portacaval shunting. Diminished renal ammonia release and enhanced muscle ammonia uptake are important mechanisms by which the cirrhotic patient maintains ammonia homeostasis after portasystemic shunting.

Abstract
AIM: To assess the impact of transjugular intrahepatic portosystemic shunt (TIPS) on pulmonary gas exchange and to evaluate the use of TIPS for the treatment of hepatopulmonary syndrome ( HPS ).
METHODS: Seven patients, three of them with advanced HPS, in whom detailed pulmonary function tests were performed before and after TIPS placement at the University of Alabama Hospital and at the Hospital Clinic, Barcelona, were considered.
RESULTS: TIPS patency was confirmed by hemodynamic evaluation. No changes in arterial blood gases were observed in the overall subset of patients. Transient arterial oxygenation improvement was observed in only one HPS patient, early after TIPS, but this was not sustained 4 mo later.
CONCLUSION: TIPS neither improved nor worsened pulmonary gas exchange in patients with portal hypertension. This data does not support the use of TIPS as a specific treatment for HPS. However, it does reinforce the view that TIPS can be safely performed for the treatment of other complications of portal hypertension in patients with HPS.

Abstract
During the last 15 years the transjugular intrahepatic portosystemic shunt (TIPS) procedure has become a safe and effective treatment of portal hypertension. Its major obstacle, the high rate of shunt insufficiency, is going to be solved by the availability of covered stents showing a patency rate of up to 90%. The treatment of acute oesophageal and gastric variceal bleeding is an unsolved problem because variceal bleeding remains the major cause of death in patients with cirrhosis. TIPS has become the rescue treatment of choice because it combines high efficacy with low invasiveness. In this context, the timing of the rescue TIPS is of major importance for achieving definitive haemostasis before multi-organ failure develops. In the prevention of re-bleeding, TIPS is accepted as a second-line treatment, required in about 10-20% of patients. TIPS may be indicated when more than two significant re-bleedings occurred within a time frame of 12 months in spite of adequate first-line measures i.e. drugs or ligation. Refractory ascites is the third main indication for TIPS. Five randomized studies comparing TIPS with paracentesis show good response and comparable survival. Interpretations of authors and comments of reviewers are, however, controversial and do not permit a definitive recommendation.

Abstract
Portal hypertension bleeding is a common and serious complication of cirrhosis. All patients with cirrhosis should undergo endoscopy and be evaluated for possible causes of current or future portal hypertensive bleeding. Possible causes of bleeding include esophageal varices, gastric varices, and PHG. Patients with esophageal varices at high risk of bleeding should be treated with nonselective beta-blockers for primary prevention of variceal hemorrhage. HVPG measurements represent the optimal way to monitor the success of pharmacologic therapy. EVL may be used in those with high-risk varices who do not tolerate beta-blockers. When active bleeding develops, simultaneous and coordinated attention must be given to hemodynamic resuscitation, prevention and treatment of complications, and active control of bleeding. In cases of acute esophageal variceal (Fig. 5) and PHG bleeding, terlipressin, somatostatin, or octreotide should be started. Endoscopic treatment is provided for those with bleeding esophageal varices. If first-line therapy fails, TIPS or surgery may need to be performed. Unlike esophageal variceal or PHG bleeding, there is no established optimal treatment for gastric variceal bleeding. Individual and specific treatment modalities for acute gastric variceal bleeding must be calculated carefully after considering side effects.

Abstract
The aim of this study was to evaluate the cardiac effects of transjugular intrahepatic portosystemic shunts (TIPS) in cirrhotic patients with different effective blood volume. Two-dimensional echocardiography was performed before and 7 and 28 days after TIPS insertion in 7 cirrhotic patients with PRA <4 ng/mL/h (group A, normal effective blood volume) and 15 with PRA >4 ng/mL/h (group B, reduced effective blood volume). Before TIPS, most cirrhotic patients showed diastolic dysfunction as indicated by reduced early maximal ventricular filling velocity (E)/late filling velocity (A) ratio. Patients of group B differed from patients of group A because of smaller left ventricular volumes and stroke volume, indicating central underfilling. After TIPS insertion, portal decompression was associated with a significant increase of cardiac output (CO) and a decrease of peripheral resistances. The most important changes were recorded in patients of group B, who showed a significant increase of both the end-diastolic left ventricular volumes and the E/A ratio and a significant decrease of PRA. In conclusion, these results show that the hemodynamic effects of TIPS differ according to the pre-TIPS effective blood volume. Furthermore, TIPS improves the diastolic cardiac function of cirrhotic patients with effective hypovolemia. This result is likely due to a TIPS-related improvement of the fullness of central blood volume.
