BACKGROUND Recent small studies on hepatorenal syndrome (HRS) indicate some clinical benefit after transjugular intrahepatic portosystemic stent-shunt (TIPS) but sufficient long term data are lacking.

AIM We studied prospectively feasibility, safety, and long term survival after TIPS in 41 non-transplantable cirrhotics with HRS (phase II study).

PATIENTS AND METHODS HRS was diagnosed using current criteria (severe (type I) HRS, n=21; moderate (type II) HRS, n=20). Thirty one patients (14 type I, 17 type II) received TIPS (8–10 mm) while advanced liver failure excluded shunting in 10. During follow up (median 24 months) we analysed renal function and survival (Kaplan-Meier).

RESULTS TIPS markedly reduced the portal pressure gradient (21 (5) to 13 (4) mm Hg (mean (SD)); p<0.001) with one procedure related death (3.2%). Renal function deteriorated without TIPS but improved (p<0.001) within two weeks after TIPS (creatinine clearance 18 (15) to 48 (42) ml/min; sodium excretion 9 (16) to 77 (78) mmol/24 hours) and stabilised thereafter. Following TIPS, three, six, 12, and 18 month survival rates were 81%, 71%, 48%, and 35%, respectively. As only 10% of non-shunted patients survived three months, total survival rates were 63%, 56%, 39%, and 29%, respectively. Multivariate Cox regression analysis revealed bilirubin (p<0.001) and HRS type (p<0.05) as independent survival predictors after TIPS.

CONCLUSIONS TIPS provides long term renal function and probably survival benefits in the majority of non-transplantable cirrhotics with HRS. These data warrant controlled trials evaluating TIPS in the management of HRS.

Statistics from

Hepatorenal syndrome (HRS) is a common and severe complication of advanced liver cirrhosis. After the onset of HRS, patients have only a minimal chance of renal functional recovery and a poor prognosis under medical therapy. Nine out of 10 patients with advanced HRS die within 10 weeks, most within the first month after diagnosis.1 To date, the only established therapy that guarantees long term improvement in renal function and prolongation of survival is timely liver transplantation.2 3 However, most of these patients are non-transplant candidates at the time of HRS diagnosis but require intensive medical management which may include haemodialysis in some patients.4 Furthermore, transplant organ shortage limits urgent transplant even for transplantable patients.

Patients with refractory ascites who are at high risk of HRS can be effectively treated by insertion of a transjugular intrahepatic portosystemic stent-shunt (TIPS). However, data on recovery of renal function after TIPS in these patients are controversial. One study reported an increase in glomerular filtration rates (GFR) in six month survivors.5 In another small randomised trial comparing TIPS with large volume paracentesis for refractory ascites, GFR improved only marginally after TIPS while natriuresis increased significantly.6 As refractory ascites and HRS share a similar pathophysiology,2 TIPS has been tried as a rescue measure in patients with advanced HRS. So far, preliminary short term data are favourable. However, these series are small (1–7 severe HRS patients) and often lack follow up data beyond three months.7-14 Furthermore, HRS was often defined differently and included patients who were candidates for transplant rescue.7 8 10 12 This hampers outcome analysis, especially for those high risk cirrhotic patients who are actually not transplant candidates at the time of HRS diagnosis.

The present phase II study provides prospective long term data on HRS outcome following TIPS as rescue treatment in a large cohort of cirrhotics in whom liver transplantation was contraindicated at the time of HRS diagnosis.

Patients and methods


Between January 1995 and November 1998 we evaluated 45 consecutive patients with advanced cirrhosis of the liver, refractory ascites, and recently detected renal insufficiency. Forty one of these patients (25 males, 16 females) were excluded from liver transplantation as a therapeutic option and were enrolled in the present study of non-surgical management (table 1). The cause of liver cirrhosis was alcoholism in 31 patients and chronic viral hepatitis in eight. Two patients had cryptogenic cirrhosis. Within two months prior to detection of renal insufficiency, 22 patients (54%) had suffered clinical complications related to portal hypertension, such as upper gastrointestinal haemorrhage (12 patients) and spontaneous bacterial peritonitis (10 patients). These complications had been effectively treated and none of these patients had a relapse within at least two weeks prior to diagnosis of renal failure. At presentation, 26 alcoholics were still active drinkers and nine of these had suffered recent severe alcohol abuse and clinically suspected concomitant acute alcoholic hepatitis (liver biopsy was performed in two and confirmed the clinical diagnosis). Thirty one patients were considered eligible for TIPS as an ultimate rescue treatment whereas 10 (25%) were excluded from TIPS because of one or more persistent contraindications (bilirubin levels ⩾15 mg/dl (five), Child-Pugh points >12 (four), or spontaneous severe encephalopathy (three)).

Clinical baseline characteristics of non-transplant cirrhotics with hepatorenal syndrome (HRS) (n=41)

All patients were studied after a minimum of five days without diuretics on a 50 mmol/day sodium diet as part of their oral nutrition. Oliguric patients had a bladder catheter inserted during diagnostic work up. Assessment of renal function was based on at least 2–3 samples of daily urine volume and serum parameters obtained prior to individual treatment assignment. All patients fulfilled recent consensus criteria for HRS,2 which are, in brief: proven liver cirrhosis with severe ascites; no recent nephrotoxic medication or severe fluid losses; no renal abnormalities on ultrasound; no nephritic sediment; proteinuria less than 500 mg/day; no signs of active infection or other reasons for renal impairment; and finally no improvement in renal function after withdrawal of diuretics and appropriate volume expansion (200 ml of 20% albumin and/or 1–2 litres of isotonic saline). HRS was graded as HRS type I (severe and rapidly progressive: serum creatinine >2.5 mg/dl or creatinine clearance <20 ml/min; >50% loss in clearance within two weeks) or HRS type II (moderate and stable or slowly progressive: serum creatinine >1.5 mg/dl or creatinine clearance <40 ml/min). Overall, we diagnosed 21 patients with type I and 20 with type II HRS. Fourteen patients with type I HRS (seven of whom required haemodialysis due to persistent oligoanuria with life threatening pulmonary oedema and hyperkalaemia) and 17 with type II HRS received TIPS treatment. The median interval from the first detection of renal insufficiency to TIPS insertion was shorter in type I HRS (2.2 weeks; range 0.3–6) than in type II HRS (4.0 weeks; range 1.5–5) but mean values were not significantly different (3.0 (1.6) v 4.3 (0.3) weeks). Among the 10 non-stented patients, seven had type I and three had type II HRS. Preliminary short term data on changes in renal function up to six months after TIPS treatment in 16 of our patients (six with type I and 10 with type II HRS) have been reported previously.13

All patients were considered ineligible for liver transplantation for the following reasons (table 1): active alcoholism (n=26), ineligibility for major surgery (age over 65 years or advanced cachexia) (n=14), and recent oropharyngeal cancer (n=1). Six active alcoholics and four patients considered poor candidates for major surgery were excluded from TIPS and received the best medical support, including adequate volume/electrolyte management, paracentesis and albumin substitution, and vasoconstrictive drugs, as indicated.2 Patients gave written informed consent for TIPS as a salvage procedure as well as for portal and systemic blood sampling according to the study protocol which was approved by the local ethics committee.


The day before the scheduled TIPS insertion all patients received a therapeutic paracentesis followed by intravenous administration of albumin (8 g/l ascites volume). After an overnight fast and bed rest, patients were taken to the radiology department for the TIPS procedure. We punctured the portal system under ultrasound guidance using a 9 French liver biopsy needle (Cook, Germany) and established small diameter (8–10 mm) stent-shunts either with Palmaz stents or Wallstents, as described in other TIPS reports.15-17 Our target was a reduction in portal pressure gradient (portal minus vena cava superior pressure) of 30–50%. In patients with no or only mild ascites after paracentesis this gradient differs only minimally from the more commonly assessed gradient of portal minus vena cava inferior pressure.18 For technical reasons, to minimise the amount of contrast media as well as the duration of the procedure, we used the modified gradient to assess the relative pressure changes induced by TIPS. The initial technical success rate was 100% without apparent adverse effects during the TIPS procedure. Patients received a single dose of antibiotic prophylaxis of cefuroxime (1.5 g), and midazolam (5–15 mg) with pethidine (75–150 mg) for anaesthesia. Intravenous heparin was given for prevention of shunt thrombosis (bolus dose of 2500–5000 U followed by constant infusion for 1–2 weeks, targeted at an activated partial thromboplastin time of 60–80 seconds). TIPS patency was monitored by repeated Doppler ultrasound (twice weekly within the first two weeks) and routine radiography 10–17 days after TIPS in all but two patients. Thereafter, Doppler ultrasound was performed every 2–3 months or whenever clinically indicated. Additional radiography was performed only for suspected TIPS dysfunction. TIPS patency was maintained during the study period in all patients. Following a minimum of one week after TIPS, diuretics were gradually reintroduced (spironolactone 50–200 mg/day and frusemide 20–80 mg/day) if daily spontaneous excretion had doubled and/or exceeded 10 mmol/day. Vasoactive drugs were not administered.


Renal function parameters (serum creatinine, serum urea, creatinine clearance, urine volume, sodium excretion/UNaV) were assessed before and at 1, 2, 4, 8, 12–13, and 24–26 weeks, and then every 2–3 months after the TIPS procedure. Overall mean follow up time was 116 weeks (median 104; range 8–212). TIPS patients were followed for at least five months or until death and their mean follow up period was 128 weeks (median 126; range 22–212).


We collected plasma (EDTA) from the last 20 consecutive TIPS patients (11 type I and nine type II HRS) from the portal vein (prior to stenting) and from the systemic circulation to determine endothelin-1 (ET-1, ELISA assay, reference values 0.73 (0.03) pmol/l) levels and activation of the renin-angiotensin system. The latter was estimated by measuring plasma renin activity (PRA) in 12 (RIA assay, reference values: baseline <5 ng/ml/3 hours, stimulated <10 ng/ml/3 hours) or by active renin (AR; RIA assay, reference values: baseline <25 ng/l, stimulated <50 ng/l) in the last eight patients. A second pair of portal and systemic plasma samples were obtained during the first invasive TIPS evaluation after 12–15 days.


Follow up parameters were compared with baseline values using two sided Student's t tests or by Mann-Whitney U test, as appropriate, for patients at risk at a given time interval after confirmation of changes over time by MANOVA. Categorical data were analysed with Fisher's exact test. All values are given as mean (SD). Differences at p<0.05 were considered significant. Estimation of survival was based on the Kaplan-Meier method and on the log rank test for group comparisons. Cox regression models were used for multivariate analysis of outcome predictors. SPSS-PC+ software was used on an IBM computer.



Baseline clinical characteristics in the total study population (table 1) were similar for type I and type II HRS patients with respect to age and aetiology of liver cirrhosis, but type I HRS patients showed a more advanced degree of liver dysfunction, as assessed by routine parameters. Interestingly, despite significantly different glomerular filtration rate parameters, there was a similar reduction in serum sodium and sodium excretion in type I and type II patients.


Thirty one patients received TIPS (table 1) on average 3.4 (1.3) weeks after detection of renal insufficiency, which reduced the portal pressure gradient from 21 (4) to 13 (5) mm Hg (p<0.001). Within the first month after TIPS, we observed marked improvements in all renal function parameters (MANOVA, p<0.01) whereas parameters of liver function showed a transient deterioration (table 2). Thereafter, renal function showed sustained stabilisation (fig 1) under careful reintroduction of diuretics (100–200 mg of spironolactone and 40–80 mg of frusemide per day). There was a marked and significant spontaneous increase in urinary sodium excretion by one week after TIPS insertion when patients were not receiving diuretics (fig 1, table 2). Interestingly, it was possible to withdraw haemodialysis in four of seven patients (days 12, 14, 18, and 22). These patients survived at least 10 months with compensated renal function (serum creatinine 2.1, 1.9, 1.8, and 1.6 mg/dl). Parallel with increased sodium excretion (>50 mmol/24 hours), ascites improved in 14 patients and completely resolved in 10. However, seven of 31 patients (23%) did not respond and still had refractory ascites needing paracentesis after one month. All but one died within three months after TIPS.

Note that all values prior to and up to one week after TIPS were determined without diuretics. Thereafter, moderate diuretic medication with furosemide (40–80 mg/day) and spironolactone (100–200 mg/day) was reintroduced and adapted to the patients’ needs.

With respect to non-TIPS patients, renal function worsened progressively in all but one patient. One young man with histological signs of acute alcohol hepatitis and chronic liver cirrhosis experienced gradual recovery from type I to type II HRS. He was the only non-TIPS patient who survived more than three months after HRS onset.


During the first year of follow up we observed major shunt stenosis in six patients and complete shunt occlusion in one man. TIPS function was successfully re-established by balloon dilatation (three) or by stent prolongation (three) in six patients, while in one patient lethal sepsis excluded reintervention at the time of diagnosis of TIPS dysfunction.

Within four weeks after TIPS, patients experienced on average a mild transient deterioration in some liver function parameters (table 2). During the first three months after TIPS we observed de novo severe encephalopathy in three patients or deterioration in pre-existing mild to moderate encephalopathy in eight patients. Six of these patients had limited short term episodes managed by lactulose but five experienced progressive liver failure. Of note, six of these 11 patients had continued alcohol abuse after TIPS and hospital release.


Mean baseline systemic ET-1 was elevated 2–3-fold above the upper normal limit and remained unchanged after TIPS. Baseline portal ET-1 was higher than ET-1 in the peripheral systemic circulation and decreased significantly after TIPS (table 2). In contrast, portal and systemic activation of the renin-angiotensin system (estimated by PRA and AR) were similar and both decreased from an eightfold elevation above normal to a 2–3-fold elevation two weeks after TIPS, despite reintroducing diuretic therapy (table 2).


Survival rates (Kaplan-Meier) of the total cohort were 63%, 56%, 39%, and 29% after three, six, 12, and 18 months, respectively, with a mean survival of 75 (14) weeks (95% CI 48–102, median 34). TIPS patients showed significantly better survival than non-TIPS patients with more advanced liver dysfunction at baseline (log rank 18.3; p<0.001) (fig 2A, 2D). After TIPS, three, six, 12, and 18 month survival rates were 81%, 71%, 48%, and 35% (mean survival 92 (16) weeks; 95% CI 60–123; median 49) compared with non-TIPS patients (three month survival of 10% and a mean survival of 12 (8.5) weeks (95% CI 0.01–28; median 2.0)). Type II HRS patients had a better chance of survival than type I patients (log rank 5.04; p=0.025) (fig2B). TIPS patients whose ascites were mobilised within one month (clinical responder) survived longer than patients who did not respond (log rank 46.6; p<0.001) (fig 2C). Interestingly, even type I patients treated with TIPS (n=14) achieved three, six, and 12 month survival rates of 64%, 50%, and 20%, which were significantly better than the survival rates of type I patients who did not undergo TIPS (n=7; p<0.01) with similar renal dysfunction at baseline (fig 2D; direct Kaplan-Meier comparison not plotted). Combined survival analysis of all 21 type I HRS patients showed three, six, and 12 month survival rates of 48%, 38%, and 16% (Kaplan-Meier plot not shown).

For the TIPS patients, multivariate Cox regression analysis, including baseline factors that were univariately related to death (bilirubin, prothrombin time, Child-Pugh, type of HRS), revealed only bilirubin (p<0.001) and type of HRS (p<0.05) as independent survival predictors. Most deaths after TIPS (83%) were related to progressive liver failure. One patient suffered a procedure related fatal liver haemorrhage and two TIPS patients died from non-liver related events (week 22, cancer progress; week 45, sepsis caused by colon perforation as diagnosed at autopsy). Subgroup survival analysis in TIPS patients showed that three month survivors had better baseline liver function (bilirubin 1.7 (1) v 8.7 (5.3) mg/dl, p<0.001; Child-Pugh score 9.2 (1.3)v 10.8 (1), p=0.08) but similar renal dysfunction (creatinine clearance 20 (12) v18 (15) ml/min, NS) compared with non-survivors.


Transplant re-evaluation in three month survivors revealed that 10 of 16 initially active alcoholics still abused alcohol after successful TIPS treatment. Six of these 10 persistent alcoholics died within one year after TIPS. In the remaining six, three month survivors (five after TIPS, one without TIPS) who had stopped drinking, liver function improved gradually after 2–3 months so that transplantation was not necessary within the first six months of our study period. Two of these patients who abstained were successfully transplanted seven months and two years after TIPS with stable renal function (serum creatinine 1.0 and 1.8 mg/dl, no ascites).


In this phase II study, we have reported on a larger cohort of non-transplantable cirrhotics with HRS diagnosed according to recent consensus criteria. The median follow up of two years after HRS diagnosis provides the longest HRS outcome analysis apart from post-transplant series.2 3 The majority of our cohort experienced sustained improvement in kidney function together with a remarkably high overall one year survival rate of almost 40%. We attribute this benefit to the fact that we considered about 75% of our patients eligible for TIPS as rescue treatment, of whom 77% (24/31) (that is, 59% of the total cohort) exhibited rapid and sustained improvement in GFR and sodium excretion. This response allowed reintroduction of mild diuretic therapy and even withdrawal from haemodialysis in four of seven patients. However, 25% of our high risk patients were excluded from undergoing TIPS because of poor liver function, and almost 25% of TIPS patients did not respond. Both of the latter groups showed a poor prognosis (fig 2C, 2D) similar to previous reports,1 with a median survival of approximately 2 weeks. As our total cohort was comparable with earlier large HRS series1 3 4 with respect to renal and liver function, it is unlikely that the more favourable outcome resulted primarily from patient selection. In addition, even overall survival in the subgroup of our 21 type I HRS patients (14 treated by TIPS) was remarkably high, with three and six month survival rates of 48% and 38% compared with the largest series of HRS patients1 (in which probably most but not all had type I HRS) which showed a three month survival rate of 9% under medical treatment (long term survival rates were not given; median survival 1.7 weeks). Thus it is likely that former HRS series probably included a high proportion of patients who today might benefit from TIPS as a salvage measure.

Although liver transplantation is the treatment of choice for cirrhotic patients with HRS, less invasive approaches have been evaluated because many of these patients are non-transplant candidates (for example due to advanced age, cachexia, and/or active alcoholism). Alternative non-surgical medical approaches using prostaglandins, vasopressin analogues, dopamine, octreotide, orN-acetylcysteine are based mainly on short term applications in small series.2 19-26 Data on vasoactive drugs used as a bridge to transplantation are promising but still unclear.27 28 Long term administration of vasopressin analogues appears to be effective but is often contraindicated or limited by severe vasoconstrictive side effects.20-23

TIPS is a more recent option for the treatment of HRS by semi-invasive portal decompression. Compared with other series, our study provides long term data based on the largest cohort of cirrhotics with HRS diagnosed as type I or type II according to current consensus criteria.2 Of note is the fact that outcome was not influenced by timely transplant rescue within the first critical months after HRS diagnosis, as at baseline all patients were non-transplant candidates. It is well known that portal decompressive surgery (that is, a portacaval end-to-side anastomosis or a side-to-side shunt) not only prevents recurrent bleeding but also prevents the formation of ascites in a larger number of patients than therapies that do not lower portal hypertension.29 As HRS is the extreme form of refractory ascites, it is sensible to treat HRS with TIPS, especially as this procedure does not carry the risk of open surgery.

Timely TIPS insertion is probably crucial for successful HRS management. Based on our data, recovery was still possible 4–6 weeks even after type I HRS onset in anuric patients who were bridged to TIPS by haemodialysis. However, a clear time limit for TIPS has yet to be defined. As all HRS patients have severe ascites and suffer spontaneously reduced food consumption, chronic fatigue with prolonged bed rest, and progressive muscle atrophy, serum creatinine and urea levels are low in relation to endogenous creatinine clearance data (tables 1, 2). This discrepancy may lead to diagnostic overestimation of GFR with delayed HRS diagnosis.

The pathogenesis of HRS is still incompletely understood.2 27 28 30-35 Cirrhotic patients with HRS suffer from peripheral and splanchnic vasodilatation combined with severe renal vasoconstriction mediated by several vasoconstrictive factors such as renin, catecholamines, endothelins, and prostaglandin derivatives.35-39 In this situation TIPS insertion not only leads to portal decompression but also to better refilling of the central venous system, although the peripheral hyperdynamic status persists.39-41 Improved refilling can decrease several vasoconstrictors and thus contribute to better renal perfusion leading to an increase in GFR and sodium excretion.39 These considerations are supported by the observed lesser activation of the renin-angiotensin system after TIPS insertion in our patients despite reintroduction of diuretics, which probably blunts further renin decline to a certain degree. Beneficial short term effects of TIPS on renin activity have been reported in patients with refractory ascites39-41 and with HRS.14 Interestingly, we detected a significant reduction in portal ET-1 levels, while elevated systemic ET-1 levels remained unchanged after TIPS. Similar differences in ET-1 levels between the portal and renal compartment have been described in cirrhotics with ascites after TIPS.42 Both observations indicate that local or paracrine ET-1 may be more relevant for kidney dysfunction in HRS than circulating ET-1.14 23 42-45 Furthermore, a decrease in sinusoidal pressure after TIPS may reduce renal sodium retention of the proximal tubule mediated by a sympathetic nervous pathway. Indeed, animal experiments suggest such a hepatorenal reflex, as an acute rise in sinusoidal pressure caused immediate sodium retention.37 46 Also, in humans, an increase in short term portal pressure induced an immediate reduction in renal perfusion.47

Despite potential benefits in renal function, TIPS affects portal venous liver perfusion and thereby carries the risk of progressive liver failure. Therefore, we restricted its placement to patients whose livers were considered to have enough residual capacity to counterbalance reduced perfusion. We excluded patients with Child-Pugh scores >12, bilirubin levels ⩾15 mg/dl, or those with severe spontaneous encephalopathy. We are aware that these criteria have been arbitrarily set and that the bilirubin limit in particular was quite generous but reasonable for the given desperate therapeutic situation. Regarding the Child-Pugh score criteria, another report applied similar restrictions.14 However, we need more controlled data to improve selection regarding the degree of liver dysfunction. In our series early mortality in patients with high baseline bilirubin levels was still substantial after TIPS. This result is similar to outcome data in other reports on shunting or endoscopic treatments for portal hypertension.15-17 48 Thus prior to TIPS treatment, bilirubin should preferably be stable below 5 mg/dl. We are aware that this criterion probably excludes many cirrhotic patients with HRS and concomitant acute alcoholic hepatitis from early TIPS. However, these patients may become TIPS candidates when HRS persists even after recovery of liver function under strict alcohol abstinence. Such a consideration encourages the option of transient dialysis treatment, at least in some patients. In the majority of our stented patients with stable bilirubin levels prior to TIPS we observed only mild and transient deteriorations in liver function applying small diameter shunts with limited initial portal decompression (35–45%, measured for technical reasons as reduction in portal vein to vena cava superior pressure gradient). Compared with initial mean portal pressure gradient reductions of approximately 50–60% reported in other TIPS series5-11 14 15 39-41 our more cautious portal decompression together with our selection criteria for TIPS treatment may have contributed to the rather favourable long term outcome of our total HRS cohort.

In conclusion, limited portal decompression by TIPS represents a promising new option for treating selected HRS patients with sustained efficacy, even without liver transplantation, and warrants further prospective controlled trials in non-transplant and even in transplant candidates. We believe that our long term data provide an adequate basis to plan such controlled trials on the role of TIPS in the management of HRS.
