The transjugular intrahepatic portosystemic shunt in the treatment of portal hypertension: current status

Purastat as an Adjunct Treatment Option in Acute Esophageal Varices Bleeding: A Case Report

Esophageal varices are dilated submucosal esophageal veins that connect the portal and systemic circulations. Bleeding esophageal varices is a well-recognized complication of liver cirrhosis.It is known that in active variceal bleeding, treatment needs to be started promptly. Treatments comprise band ligation, sclerotherapy, removable stent placement, balloon tamponade, and transjugular intrahepatic portosystemic shunt (TIPS).We report a case in which hemodynamic stability can be maintained with the use of Purastat to control bleeding.

Enzymatic liver function measured by LiMAx is superior to current standard methods in predicting transplant-free survival after TIPS implantation

Transjugular intrahepatic portosystemic shunt (TIPS) is one of the main treatment options in patients with decompensated liver cirrhosis but is still associated with partly severe complications. For adequate patient selection, prognostic parameters are of crucial importance. The liver maximum capacity (LiMAx) breath test measures enzymatic liver function and could potentially represent an efficient prognostic marker. We therefore aimed to assess the role of LiMAx in predicting survival of TIPS patients in a prospective analysis. LiMAx was performed for patients who underwent TIPS implantation between October 2016 and February 2018. Associations with transplant-free survival after 24 weeks were assessed by logistic regression. A total number of 30 patients were included, of whom seven received liver transplantation (N = 2) or died (N = 5) during follow-up. LiMAx values after (P = 0.01, OR = 1.24, 95% CI = 1.04-1.47) and before (P = 0.03, OR 1.21, 95% CI = 1.02-1.43) TIPS implantation and MELD score (P = 0.03, OR = 0.79, 95% CI = 0.63-0.98) were significantly associated with transplant-free survival according to univariate logistic regression. In AUROC analysis, LiMAx at day one after TIPS (sensitivity 85.7%, specificity 78.3%, AUROC 0.85, cut-off ≤ 165 µg/kg/h), LiMAx value at the day before TIPS (sensitivity 100%, specificity 73.9%, AUROC 0.82, cut-off ≤ 205 µg/kg/h) and MELD score (sensitivity 71.4%, specificity 73.9%, AUROC 0.82, cut-off ≥ 15) had the highest prognostic accuracy. LiMAx values prior and after TIPS procedure seem to be good prognostic parameters regarding prediction of transplant-free survival of patients undergoing TIPS implantation.

Outcomes of transjugular intrahepatic portosystemic shunt procedures: a 10-year experience

INTRODUCTION

Transjugular intrahepatic portosystemic shunt (TIPSS) is an effective modality in reducing portal pressure, and its current main indications are for the management of recurrent ascites and variceal bleeding. The demand and indications for TIPSS are growing. However, it is a complicated and technically demanding procedure with poorer outcomes associated with low volume centres. The aim of this study was, therefore, to review the outcomes of TIPSS at a 'low volume' single centre. Outcomes assessed included indications, safety, efficacy and survival.

METHODS

A retrospective study was undertaken of all patients who underwent a TIPSS procedure over 10 years at tertiary referral centre for complex liver disease and transplantation. Kaplan-Meier method was used to calculate actuarial survival and log-rank analysis was used to determine significant differences in survival.

RESULTS

Thirty-eight patients underwent the TIPSS procedure between January 2008 and December 2018. Technical, haemodynamic and clinical success were 95%, 92% and 92% respectively. Cumulative survival at one month, one year and five years were 86.8%, 72% and 44.7% respectively. Results achieved standards published in practice parameters to evaluate TIPSS safety and efficacy.

CONCLUSION

At a low volume centre, TIPSS usage was associated with high rates of technical, haemodynamic (HPVG reduction) and clinical success. Low volume should not be a contraindication to providing a TIPSS service; however, auditing outcomes and understanding specific institutional factors that influence quality are important requirements for low volume centres.

The place of endoscopy in the tactics of restoring the viability of patients with gastroesophageal bleeding in portal hypertension (literature review)

Portal hypertension is a symptom complex that develops as a result of impaired blood flow in the portal system, the leading symptom of which is an increase in pressure in the portal vein over 12 mm Hg. Art. According to statistics in developed countries, 90% of cases of portal hypertension are associated with liver cirrhosis. The most formidable and fatal complication of portal hypertension is bleeding from varicose veins of the esophagus and stomach. The risk of bleeding is 4–5% per year, and in the presence of varicose veins of the esophagus from 15 to 30% or more, the mortality rate is 50%, with a recurrence rate of 50 to 90%. And the fact that today there is no unified approach to solving this problem in the world prompted us to take a short literary review on this topic.

Transjugular intrahepatic portosystemic shunt (TIPS) in Spain. Clinical-epidemiological considerations in relation to a multicenter registry

OBJECTIVE

this study aimed to determine the epidemiological, technical and clinical data of transjugular intrahepatic portosystemic shunt (TIPS) performed by Interventional Radiology departments in Spain. Furthermore, the total number of TIPS carried out in Spain was determined and compared with other countries.

MATERIAL AND METHODS

a retrospective study was performed with the approval of the Ethical Committee of the Spanish Society of Interventional Radiology (SERVEI). A survey was performed with 31 items (demographic, technical and clinical data) for data acquisition on the current status of TIPS in Spain. The survey was sent to the 49 hospitals that SERVEI included in a previous registry with data of TIPS performed in Spain in 2016.

RESULTS

of the 49 centers surveyed, 33 (67.35 %) replied to the survey. These centers had completed 265 of the 415 TIPS that year in Spain. The most frequent indication was upper GI bleeding from gastroesophageal varices, which accounted for 144 (54.33 %); 62.26 % of the TIPS were performed urgently and 37.7 % on a scheduled basis. The technical success was 89.16 ± 20.9 %, with a rebleeding rate of 17.9 %. Sixty-nine patients (26.03 %) presented complications, 19.62 % of them minor and 6.41 % major. The 30-day mortality related to the disease was 14.33 %, while mortality at one year was 18.49 %.

CONCLUSION

notably in our study, the complications of TIPS did not show a clear relationship with the number of procedures performed. With regard to other countries like the United States and France, the number of TIPS in Spain per million inhabitants is currently substantially lower. There were no significant changes compared to the number completed in 2013.

ePTFE-TIPS vs repetitive LVP plus albumin for the treatment of refractory ascites in patients with cirrhosis

BACKGROUND & AIMS

Reduction in portal pressure by self-expandable polytetrafluoroethylene (ePTFE)-covered transjugular intrahepatic portosystemic shunts (TIPS) is a treatment option for refractory ascites. Data on clinical outcomes after ePTFE-TIPS vs repetitive large-volume paracentesis (LVP) plus albumin (A) administration for the treatment of patients with refractory ascites are limited.

METHODS

Retrospective comparison of ePTFE-TIPS vs LVP+A in terms of (i) control of ascites, (ii) occurrence of overt hepatic encephalopathy (HE) and (iii) transplant-free survival in cirrhotic patients with refractory ascites.

RESULTS

Among n = 221 patients with cirrhosis and refractory ascites, n = 140 received ePTFE-TIPS and were compared to n = 71 patients undergoing repetitive LVP+A. After ePTFE-TIPS, ascites was controlled without any further need for paracentesis in n = 76 (54%; n = 7 without and n = 69 with diuretics). The need for frequent large-volume paracentesis was significantly higher in the LVP+A group than with ePTFE-TIPS (median 0.67 (IQR: 0.23-2.63) months vs 49.5 (IQR: 5.07-102.60) months until paracentesis, log-rank P < .001). De-novo incidence of HE was similar in ePTFE-TIPS and LVP+A patients (log-rank P = .361). Implantation of ePTFE-TIPS was associated with improved 1-year survival as compared to LVP+A (65.6% vs 48.4%, log-rank P = .033). Age (odds ratio (OR):1.05; 95% confidence interval (95% CI):1.03-1.07; P < .001), serum albumin (OR: 0.95; 95% CI: 0.92-0.99; P = .013) and hepatocellular carcinoma (OR: 1.66; 95% CI: 1.06-2.58; P = .026) emerged as independent predictors of survival.

CONCLUSIONS

ePTFE-TIPS results in superior control of ascites without increasing the risk for overt HE as compared to LVP+A. Although ePTFE-TIPS improved 1-year survival in cirrhotic patients with refractory ascites, its use was not independently associated with transplant-free survival.

Incidence of hepatic encephalopathy after transjugular intrahepatic portosystemic shunt (TIPS) according to its severity and temporal grading classification

OBJECTIVES

To evaluate hepatic encephalopathy (HE) incidence after transjugular intrahepatic portosystemic shunt (TIPS) and classify by gravity and frequency.

METHODS

This is a retrospective study of 75 patients with no previous episodes of HE who underwent TIPS between 2008 and 2014 with clinical follow-up after 6 and 12 months. Patient risk factors evaluated include age, INR (international normalized ratio), creatinine, bilirubin, and MELD score (Model for End-of-stage Liver Disease). HE was reported using two classifications: (1) gravity divided in moderate (West-Haven grades I-II) and severe (III-IV); (2) frequency divided in episodic and recurrent/persistent.

RESULTS

Overall HE incidence was 36% at 6 months, with 12 month incidence significantly decreased to 27% (p = 0.02). 13/75 (17%) patients had one episode of moderate HE, while 3/75 (4%) patients had severe recurrent/persistent HE. Age was the only pre-TIPS risk predictor. Post-TIPS bilirubin and INR showed variations from basal values only in the presence of diagnosed HE. Bilirubin significantly increased (p = 0.03) in correlation to HE severity, whereas INR changes correlated with temporal frequency (p = 0.04). HE distribution classified for severity is similar at 6 and 12 months, whereas when classified for frequency shows significant differences (p = 0.04).

CONCLUSIONS

A classification by gravity and frequency attests post-TIPS HE as a manageable risk. Monitoring of bilirubin and INR may help on clinical management risk stratification.

Isolated Gastric Varices Refractory to Balloon-occluded Retrograde Transvenous Obliteration (BRTO) Successfully Treated by Shunt-occluded Endoscopic Injection Sclerotherapy (SO-EIS): A Case Report and Review of the Literature

Balloon-occluded retrograde transvenous obliteration (BRTO) is widely used to treat isolated gastric varices (IGVs) in Japan. However, BRTO is difficult to perform for IGVs with many small collateral veins, and no secondary treatment has been established. We herein report a rare case of IGVs refractory to BRTO successfully treated by shunt-occluded endoscopic injection sclerotherapy (SO-EIS), which is a combination therapy of major shunt occlusion by a balloon catheter and endoscopic injection sclerotherapy. Since SO-EIS can be performed regardless of the IGVs' anatomical configuration, it may be a promising alternative treatment for IGVs refractory to BRTO.

Transjugular intrahepatic portosystemic shunt in refractory hydrothorax - a contribution to an unexplored indication

BACKGROUND AND AIMS

Hepatic hydrothorax is a rare complication of portal hypertension, but may be potentially severe. Although conservative therapy may be effective, it is not without risk and refractory cases are not rare. The portal decompression achieved by transjugular intrahepatic portosystemic shunts (TIPS) has shown positive results in the treatment of refractory ascites, and in that sense, the analysis of their value in other complications of portal hypertension becomes relevant. The aim of this study was to evaluate the efficacy and safety of TIPS in patients with refractory hydrothorax.

METHODS

This was a retrospective study including patients with refractory hydrothorax undergoing TIPS in a tertiary hospital in the period between 2000 and 2014, and evaluated the following: demographic characteristics, liver disease, and outcomes (efficacy and safety, including complications after TIPS, liver transplantation, 30-day, and 1-year mortality).

RESULTS

Nineteen patients with hydrothorax underwent TIPS; most had previously undergone multiple thoracocentesis and all had hypoalbuminemia. In all, 57.9% of the patients were men, with a mean age 63±9 years, and 84.2% had cirrhosis of alcoholic etiology and a mean Model for End-Stage Liver Disease-16, Child-Pugh B in 42.1%/Child-Pugh C in 47.4%. TIPS was effective in 73.3% of the cases. Portosystemic encephalopathy was recorded in 66.6% of the cases. Mortality was 25% at 30 days and 42.8% at 1 year with septic complications or progression of liver disease. Two patients underwent liver transplantation. The mean follow-up duration was 704 days (3-3485 days).

CONCLUSION

TIPS appears to be a relatively efficient method to control hydrothorax, making it a valid option in refractory cases despite the high risk of portosystemic encephalopathy and mortality.

Transjugular Intrahepatic Portosystemic Shunt Combined with Haemoperfusion in an End-stage Renal Disease Patient with Liver Cirrhosis-related Refractory Portal Hypertensive Variceal Bleeding: A Case Report

Transjugular intrahepatic portosystemic shunt (TIPS) is recommended as the second-line option for variceal bleeding in liver cirrhosis patients when the bleeding is not well controlled by medical and/or endoscopic therapy. However, due to a high incidence of post-TIPS hepatic encephalopathy, particularly in patients with end-stage renal disease (ESRD), TIPS is rarely used in such cases. We report a case involving the successful and safe use of TIPS combined with haemoperfusion to treat an ESRD patient with liver cirrhosis-related refractory portal hypertensive variceal bleeding. Our case suggests the possibility of inserting TIPS to stop recurrent variceal bleeding in ESRD patients with liver cirrhosis. Haemoperfusion may be used to reduce the risk of post-TIPS hepatic encephalopathy.

Transjugular intrahepatic portosystemic shunt for acute variceal gastrointestinal bleeding: Indications, techniques and outcomes

Acute variceal bleeding is a life-threatening condition that requires a multidisciplinary approach for effective therapy. The transjugular intrahepatic portosystemic shunt (TIPS) procedure is a minimally invasive image-guided intervention used for secondary prevention of bleeding and as salvage therapy in acute bleeding. Emergency TIPS should be considered early in patients with refractory variceal bleeding once medical treatment and endoscopic sclerotherapy fail, before the clinical condition worsens. Furthermore, admission to specialized centers is mandatory in such a setting and regional protocols are essential to be organized effectively. This procedure involves establishment of a direct pathway between the hepatic veins and the portal veins to decompress the portal venous hypertension that is the source of the patient's bleeding. The procedure is technically challenging, especially in critically ill patients, and has a mortality of 30%-50% in the emergency setting, but has an effectiveness greater than 90% in controlling bleeding from gastro-esophageal varices. This review focuses on the role of TIPS in the setting of variceal bleeding, with emphasis on current indications and techniques for TIPS creation, TIPS clinical outcomes, and the role of adjuvant embolization of varices.

Advances in the management of childhood portal hypertension

Portal hypertension is one of the most serious complications of childhood liver disease, and variceal bleeding is the most feared complication. Most portal hypertension results from cirrhosis but extra hepatic portal vein obstruction is the single commonest cause. Upper gastrointestinal endoscopy endoscopy remains necessary to diagnose gastro-esophageal varices. Families of children with portal hypertension should be provided with written instructions in case of gastrointestinal bleeding. Children with large varices should be considered for primary prophylaxis on a case-by-case basis. The preferred method is variceal band ligation. Children with acute bleeding should be admitted to hospital and treated with antibiotics and pharmacotherapy before urgent therapeutic endoscopy. All children who have bled should then receive secondary prophylaxis. The preferred method is variceal band ligation and as yet there is little evidence to support the use of β-blockers. Children with extrahepatic portal vein obstruction should be assessed for suitability of mesoportal bypass.

Comparative study of endoscopy vs. transjugular intrahepatic portosystemic shunt in the management of gastric variceal bleeding

Background and Aim: Gastric varices are associated with high mortality. There have been conflicting reports on whether endoscopic treatment with cyanoacrylate or the placement of a transjugular intrahepatic portosystemic shunt (TIPS) is more effective in the treatment of gastric varices. We compared the outcomes of patients treated with cyanoacrylate glue or TIPS for the management of acute gastric variceal bleeding.

Methods: The study was designed as a retrospective cohort analysis of patients undergoing either TIPS or endoscopic treatment with cyanoacrylate for acute gastric variceal bleeding at our institution from 2001 to 2011. Primary compared to studied between the two treatment modalities were the short-term treatment outcomes, including re-bleeding within 30 days, length of hospital stay and in-hospital mortality. Kaplan-Meier survival analysis was performed to assess factors associated with in-hospital mortality.

Results: A total of 169 patients were included in the analysis. The TIPS arm contained 140 patients and the cyanoacrylate arm contained 29 patients. There was no evidence to suggest any significant differences in demographics or disease severity. There were no differences between the TIPS arm and the cyanoacrylate armtwo groups in treatment outcomes including re-bleeding within 30 days (17.4% vs. 17.2%; P = 0.98), median length of stay in the hospital (4.5 days vs. 6.0 days; P = 0.35) or in-hospital mortality (9.0% vs. 11.1%; P = 0.74). In-hospital mortality was evaluated for 149 patients and lower albumin (P = 0.015), higher MELD score (P < 0.001), higher CTP score (P = 0.005) and bleeding (P = 0.008) were all significantly associated with in-hospital death.

Conclusion: These findings suggest that both treatments are equally effective. Cyanoacrylate offers a safe, effective alternative to TIPS for gastric varices, and physician may choose the best therapy for each patient, factoring in the availability of TIPS or cyanoacrylate, the individual patient’s presentation, and cost.

The Evolution of Transjugular Intrahepatic Portosystemic Shunt: Tips

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.

TIPS: 25 years later

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.

Portacaval shunt established in six dogs using magnetic compression technique

BACKGROUND AND AIMS

Installing the transjugular intrahepatic portosystemic shunt for portal hypertension is relatively safe, but complications are still high. To explore a new method of portacaval shunt, the magnetic compression technique was introduced into the shunting procedure.

METHODS

A portal-inferior vena cava shunt was performed on 6 male mongrel dogs by two hemocompatible Nd-Fe-B permanent magnets, parent and daughter. The parent magnet was applied to the inferior vena cava guided by a catheter through the femoral vein. The daughter magnet was moved to the anastomosis position on the portal vein with a balloon catheter through the splenic vein. After the daughter magnet reached the target position, the two magnets acted to compress the vessel wall and hold it in place. Five to 7 days later, under X-ray guidance, the magnets were detached from the vessel wall with a rosch-uchida transjugular liver access set. One month later, histological analysis and portal venography were performed.

RESULTS

5-7 days after the first surgery, a mild intimal hyperplasia in the portal vein and the inferior vena cava, and continuity of the vascular adventitia from the portal vein to the inferior vena cava as observed. During the second surgery, the contrast media could be observed flowing from the portal vein into the inferior vena cava. Portal venography revealed that the portosystemic shunt was still present one month after the second surgery.

CONCLUSIONS

Magnamosis via a device of novel design was successfully used to establish a portacaval shunt in dogs.

Long-term follow-up of TIPS created with expanded poly-tetrafluoroethylene covered stents

BACKGROUND

Transjugular intrahepatic portosystemic shunts (TIPS) created with expanded poly-tetrafluoroethylene-covered stents have largely replaced bare metal stents. Short-term shunt patency is typically assessed with protocol Doppler ultrasound (US), while little information exists with regard to long-term patency.

AIM

We investigated the value of Doppler US in assessing TIPS patency as well as long-term clinical outcomes.

METHODS

A retrospective analysis of 59 patients with covered stents used for TIPS between January 2001 and December 2011 was performed.

RESULTS

Fifty-four patients had early (median 9 days) Doppler US follow-up. Seven of eight patients with an abnormal baseline US required stent revisions. None of the 46 patients with normal baseline Doppler US required revisions within the first 6 months; six of these patients subsequently had a portogram because of symptoms, but all TIPS were patent. Fifty-two patients survived for long-term (>6 months) follow-up, averaging 654 days and three Doppler US exams. Five of six patients with abnormal follow-up Doppler US required revisions, whereas none of the 46 patients with normal follow-up US had revisions. The recurrence of symptoms of portal hypertension and/or hepatic encephalopathy (HE) was low (4/52 patients). No significant predictors of long-term stenosis were identified. Post-TIPS HE was independent of pre-TIPS HE or Child-Pugh score.

CONCLUSIONS

Short-term patency and that at approximately 2 years after TIPS placement was 87 and 77 %, respectively. We conclude that Doppler US at least 1 week after TIPS is warranted, but repeated Doppler US follow-up is probably not necessary in the absence of clinical symptoms.

Portal Hypertension in Childhood Bilateral Wilms' Tumor Survivor: An Excellent Indication for TIPS

Introduction. Increased pressure in portal venous system is relatively a rare complication after chemoradiotherapy for Wilms' tumor (WT). In paediatric population, feasibility and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) in portal hypertension nonresponsive to medical or endoscopic treatment have been recently advocated. We report a case of TIPS positioning in a 15-year-old girl with portal hypertension as a long-term sequel of multimodality therapy in bilateral WT. Case Report. Two-year-old girl was diagnosed for bilateral WT. Right nephrectomy with left heminephrectomy and chemoradiotherapy were performed. At 7 years of age, the first gastrointestinal bleeding appeared, followed by another episode two years later, both were treated successfully with beta-blockers. At 15 years of age, severe unresponsive life-threatening gastroesophageal bleeding without hepatosplenomegaly was managed by TIPS. Reduction of the portosystemic pressure gradient was obtained. Conclusion. TIPS positioning for portal hypertension in long-term tumors' sequel is feasible and could be considered as an additional indication in paediatric patients.

Progress in prevention and treatment of rebleeding after endoscopic band ligation for esophageal variceal bleeding

Hemorrhage from esophageal varices is a serious and common complication of decompensated cirrhosis and carries a significant rate of morbidity and mortality. Endoscopic variceal ligation (EVL) is an effective treatment for esophageal varices; however, there is a very high rate of rebleeding. Prevention and treatment of rebleeding after EVL are important for improving survival in patients with liver cirrhosis. Currently, many measures, including endoscopy, surgery, medication, and a combination of them, have been developed to prevent the occurrence of rebleeding after EVL. Many clinical trials have been done to evaluate the effectiveness of various treatments, alone or in combination, for rebleeding.
