Transjugular Intrahepatic Portosystemic Shunt: Devices Evolution, Technical Tips and Future Perspectives. J Clin Med 2023; 12:6758. [PMID: 37959225 PMCID: PMC10650044 DOI: 10.3390/jcm12216758] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2023] [Revised: 10/18/2023] [Accepted: 10/20/2023] [Indexed: 11/15/2023] Open
Abstract
Portal hypertension (PH) constitutes a pivotal factor in the progression of cirrhosis, giving rise to severe complications and a diminished survival rate. The transjugular intrahepatic portosystemic shunt (TIPS) procedure has undergone significant evolution, with advancements in stent technology assuming a central role in managing PH-related complications. This review aims to outline the progression of TIPS and emphasizes the significant influence of stent advancement on its effectiveness. Initially, the use of bare metal stents (BMSs) was limited due to frequent dysfunction. However, the advent of expanding polytetrafluoroethylene-covered stent grafts (ePTFE-SGs) heralded a transformative era, greatly enhancing patency rates. Further innovation culminated in the creation of ePTFE-SGs with controlled expansion, enabling precise adjustment of TIPS diameters. Comparative analyses demonstrated the superiority of ePTFE-SGs over BMSs, resulting in improved patency, fewer complications, and higher survival rates. Additional technical findings highlight the importance of central stent placement and adequate stent length, as well as the use of smaller calibers to reduce the risk of shunt-related complications. However, improving TIPS through technical means alone is inadequate for optimizing patient outcomes. An extensive understanding of hemodynamic, cardiac, and systemic factors is required to predict outcomes and tailor a personalized approach. Looking forward, the ongoing progress in SG technology, paired with the control of clinical factors that can impact outcomes, holds the promise of reshaping the management of PH-related complications in cirrhosis.

Abstract
Transjugular intrahepatic portosystemic shunt (TIPS) creation is effective in treating the sequelae of decompensated liver cirrhosis-including medically refractory ascites and variceal bleeding-by decompressing the portal venous system through a manmade portosystemic conduit within the liver. However, the altered physiology in which splenomesenteric blood bypasses intrahepatic portal venous perfusion can precipitate varying degrees of hepatic encephalopathy (HE). While the majority of post-TIPS HE cases can be treated medically, some require escalated management strategies, including endovascular interventions to modify the indwelling TIPS and/or occlude competitive physiologic spontaneous portosystemic shunts. This review article details the epidemiology, risk factors, diagnosis, classification, and treatment of post-TIPS HE.

Abstract
Complications of overshunting, including hepatic encephalopathy and hepatic insufficiency, remain prevalent following transjugular intrahepatic portosystemic shunt (TIPS) creation. Smaller diameter TIPS may reduce the risk of overshunting, but the use of smaller stents must be weighed against the risk of undershunting and persistent or recurrent hemorrhage, ascites, and other complications of portal hypertension. This article explores the question of optimal shunt diameter by examining outcomes for smaller diameter TIPS stent-grafts (<10 mm), underdilated stent-grafts, and variable diameter stent-grafts.

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.

Cardiovasc Intervent Radiol 2022; 45:542-549. [PMID: 35020042 DOI: 10.1007/s00270-021-03040-8] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Accepted: 12/02/2021] [Indexed: 12/16/2022]
Abstract
PURPOSE This study compares the safety and efficacy of the ePTFE-covered self-expansible nitinol stent (VIATORR® Controlled Expansion, Gore, Flagstaff, USA) with the ePTFE-covered, balloon-expandable, metallic stent (BeGraft peripheral, Bentley, Hechingen, Germany) for the creation of the transjugular intrahepatic portosystemic shunt (TIPS). MATERIAL AND METHODS From September 2016 to December 2020, 72 consecutive patients receiving TIPS for acute variceal bleeding (rescue and early TIPS, n = 15) or for prophylaxis of variceal rebleeding (n = 57) were enrolled. The main contraindications were patients with vascular liver disease (portal vein thrombosis and Budd-Chiari syndrome). Forty patients (55.6%) received a Viatorr CX stent and 32 patients (44.4%) a BeGraft peripheral stent. Safety endpoints were technical and clinical adverse events and early deaths within 30 days after TIPS implantation. Efficacy endpoints were rebleeding rates, recurrence of large varices requiring endoscopic band ligation, or TIPS revision. RESULTS Groups receiving the Viatorr CX or BeGraft peripheral stent were comparable in all respects except the TIPS indication for acute variceal bleeding (5% vs. 25%, p = 0.015). All patients had a successful intervention, and the physical variables of stent implantation (intervention and fluoroscopy time, reduction of the portosystemic pressure gradient) as well as adjunctive embolization of varices were similar in both groups. Severe clinical complications (Viatorr CX: 5% vs. BeGraft peripheral: 3.1%, p = 0.692), post-TIPS hepatic encephalopathy (12.5% vs. 18.8%, p = 0.743) and death (5% vs. 0%, p = 0.793) were not different between Viatorr CX and BeGraft peripheral groups. With respect to efficacy, freedom from rebleeding and from variceal band ligation during follow-up (100% vs. 100%, p = 1.0), as well as the need for shunt revision (10.5% vs. 18.8%, p = 0.327), was comparable. CONCLUSION Compared to the present gold standard, the Viatorr CX stent, the balloon-expandable BeGraft peripheral stent, showed similar results with respect to safety and efficacy.

Abstract
BACKGROUND The Viatorr Controlled Expansion (VCX) stent-graft was designed to mitigate hepatic encephalopathy (HE) after transjugular intrahepatic portosystemic shunt (TIPS) creation. AIMS To determine the incidence and degree of HE after VCX TIPS. METHODS Thirty-three patients (M:F 17:16, mean age 58 years, mean MELD score 12) who underwent VCX TIPS between 2018 and 2019 were retrospectively studied. 11/33 (33%) patients had medically controlled pre-TIPS HE. TIPS indications included variceal hemorrhage (n = 12, 30%) and ascites (n = 21, 70%). Measured outcomes were post-TIPS HE (overall, recurrent, de novo) graded using the West Haven system, time-to-HE occurrence, HE-related hospitalization rate, and TIPS reduction rate. RESULTS VCX TIPS were 8 mm in 28/33 (85%) and 10 mm in 5/33 (15%). Mean final portosystemic pressure gradient was 6 mmHg. Cumulative HE incidence post-TIPS was 61% (20/33). 1-, 3-, 6-, and 12-month HE rates were 24%, 30%, 53%, and 61% over 247-day median follow-up. Median time-to-HE was 180 days. HE grades spanned grade 1 (n = 6), grade 2 (n = 8), and grade 3 (n = 6); 9 and 11 cases were recurrent and de novo HE, respectively. Medication non-compliance/infection was implicated in HE in 9/20 (45%) cases. Medical therapy addressed HE in 18/20 (90%) cases; however, HE still resulted in 39 hospitalizations among 13 patients, and median time to first hospitalization was 75 days. Shunt reduction was necessary in 2 (10%) cases of medically refractory HE. CONCLUSIONS The incidence of HE after VCX TIPS is high. Though HE symptoms may be medically controlled, hospitalization rates are high, and shunt reduction may be necessary.

Abstract
INTRODUCTION Hepatic encephalopathy (HE) is a major complication of transjugular intrahepatic portosystemic shunt (TIPS) creation. This study was aimed to determine whether underdilated TIPS with 8-mm polytetrafluoroethylene-covered stents could reduce the risk of HE and liver damage yet maintain clinical and hemodynamic efficacy. METHODS This retrospective case-controlled study included 134 patients treated with TIPS from March 2017 to November 2019. All the TIPS procedures were created using 8-mm covered stents, and according to the diameter of expansion balloon catheters, the patients were divided into 2 groups, an underdilated group (6-mm balloon catheter, n = 73) and a control group (8-mm balloon catheter, n = 61). RESULTS The Kaplan-Meier analysis indicated that the cumulative incidence of overt HE in the underdilated group was significantly lower than that in the control group (11.0% vs 29.5%, log rank P = 0.007), but no statistical differences were found toward variceal rebleeding, shunt dysfunction, and survival between groups. In multivariate analysis, the independent risk factors for overt HE were identified as age (hazard ratio [HR] = 1.036, 95% confidence interval [CI] = 1.003-1.069, P = 0.032), Child-Pugh score (HR = 1.519, 95% CI = 1.212-1.905, P < 0.001), and group assignment (HR = 0.291, 95% CI = 0.125-0.674, P = 0.004). DISCUSSION Underdilated TIPS with 8-mm polytetrafluoroethylene-covered stents could reduce the risk of HE and liver function impairment compared with completely dilated TIPS, but not increase the risk of variceal rebleeding, shunt dysfunction, and death.

Controlled underdilation using novel VIATORR® controlled expansion stents improves survival after transjugular intrahepatic portosystemic shunt implantation. JHEP Rep 2021; 3:100264. [PMID: 34013182 PMCID: PMC8113713 DOI: 10.1016/j.jhepr.2021.100264] [Citation(s) in RCA: 26] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Revised: 02/11/2021] [Accepted: 02/17/2021] [Indexed: 12/11/2022] Open
Abstract
Background & Aims Smaller 8-mm diameter transjugular intrahepatic portosystemic shunts (TIPS) appear to be more beneficial than larger 10-mm TIPS stent-grafts, but lack the ability for secondary dilation in cases of clinical ineffectiveness. Underdilated VIATORR® TIPS stent grafts (VTS) expand passively, whereas novel VIATORR Controlled Expansion (VCX) stent grafts do not. This study evaluated the impact on survival of underdilated VCX compared with VTS in patients with decompensated cirrhosis. Methods This was a prospective case-control study including patients with cirrhosis receiving TIPS using 10-mm VCX underdilated to 8 mm. Patients with cirrhosis receiving 10-mm VTS underdilated to 8 mm were matched for age, sex, indication for TIPS, and liver function. Results A total of 114 patients (47 VCX, 47 VTS, and 20 fully dilated VCX/VTS) were included. After TIPS implantation, underdilated VCX diameter was 8.0 (7.8-9.2) mm at a median time of 359 (87-450) days, compared with VTS at 9.9 (9.7-10.0) mm (p <0.001). The portosystemic pressure gradient immediately after TIPS procedure and after 7 days did not change significantly in VCX [mean 9.4 (± 0.8) vs. 10.4 (± 0.7) mmHg, p = 0.115). Hospital readmission rates for hepatic encephalopathy were 23% (n = 11) vs 51% (n = 24) for VCX and VTS (p <0.001), respectively. Patients with VCX had significantly lower rates of large-volume paracentesis (n = 5 [11%] vs. n = 10 [21%], p = 0.017) and heart failure (n = 1 [2%] vs. n = 7 [15%], p = 0.015). One-year mortality for underdilated VCX and VTS was 15% (n = 7) and 30% (n = 14) and, for fully dilated VCX/VTS, was 45% (n = 9) (log-rank p = 0.008), respectively. Conclusions This study demonstrated that VCX stent grafts underdilated to 8 mm do not passively expand to nominal diameter and suggests reduced hospital readmissions because of hepatic encephalopathy, uncontrolled ascites, and heart failure, and improved 1-year survival compared with underdilated VTS. Lay summary Transjugular intrahepatic portosystemic shunt (TIPS) improves survival in selected patients with liver cirrhosis and acute variceal bleeding or refractory ascites. Smaller 8-mm diameter TIPS stent grafts appear to improve patient outcome compared with larger 10-mm diameter stent grafts. Novel VIATORR® Controlled Expansion (VCX) stent grafts facilitate safe and stable underdilation to 8 mm of large 10-mm diameter stent grafts with improved patient outcome (survival, hepatic encephalopathy, ascites and heart failure) compared with legacy VIATORR TIPS stent graft (VTS). Thus, the use of underdilated VCX could preserve heart function. Clinical Trials Registration The study is registered at Clinicaltrials.govNCT03628807.

Transjugular Intrahepatic Portosystemic Shunt Placement for Portal Hypertension: Meta-Analysis of Safety and Efficacy of 8 mm vs. 10 mm Stents. Gastroenterol Res Pract 2020; 2020:9149065. [PMID: 33123192 PMCID: PMC7586157 DOI: 10.1155/2020/9149065] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/18/2020] [Revised: 09/14/2020] [Accepted: 09/27/2020] [Indexed: 12/19/2022] Open
Abstract
Introduction Hepatic encephalopathy (HE) following transjugular intrahepatic portosystemic shunt (TIPS) placement remains a leading adverse event. Controversy remains regarding the optimal stent diameter given that smaller stents may decrease the amount of shunted blood and decrease the risk of HE, but stent patency and/or clinical adequacy of portal decompression may also be affected. We aim to provide meta-analysis-based evidence regarding the safety and efficacy of 8 mm vs. 10 mm stents during TIPS placement. Methods PubMed, Embase, Cochrane Library, and Web of Science were searched for studies comparing 8 mm and 10 mm stents during TIPS placement for portal hypertension decompression in cirrhotic patients. Randomized controlled trials and cohort studies were prioritized for inclusion. Overall evaluation of quality and bias for each study was performed. The outcomes assessed were the prevalence of HE, rebleeding or failure to control refractory ascites, and overall survival. Subgroup analysis based on TIPS indication was conducted. Results Five studies with a total number of 489 cirrhotic patients were identified. The pooled hazard ratio (HR) of post-TIPS HE was significantly lower in patients in the 8 mm stent group than in the 10 mm stent group (HR: 0.68, 95% CI: 0.51~0.92, p value < 0.0001). The combined HR of post-TIPS rebleeding/the need for paracentesis was significantly higher in patients in the 8 mm stent group than in the 10 mm stent group (HR: 1.76, 95% CI: 1.22~2.55, p value < 0.0001). There was no statistically significant difference in the overall survival between the 8 mm and 10 mm stent groups. The combined risk of HE in the variceal bleeding subgroup was statistically lower (HR: 0.52, CI: 0.34-0.80) with an 8 mm stent compared with a 10 mm stent. The combined risk of both rebleeding/paracentesis and survival was not statistically significant between 8 mm and 10 mm stent use in subgroup analysis. Conclusion 8 mm stents during TIPS placement are associated with a significant lower risk of HE compared to 10 mm stents (32% decreased risk), as well as a 76% increased risk of rebleeding/paracentesis. Meta-analysis results suggest that there is not one superior stent choice for all clinical scenarios and that the TIPS indication of variceal bleeding or refractory ascites might have different appropriate selection of the shunt diameter.

[PMID: 31853780 DOI: 10.1007/s10620-019-06008-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2019] [Accepted: 12/10/2019] [Indexed: 02/05/2023]
Abstract
BACKGROUND The expanded polytetrafluoroethylene (ePTFE)-covered stent has been widely used in the transjugular intrahepatic portosystemic shunt (TIPS) procedure. However, the epidemiologic data of acute TIPS occlusion (ATO) and the underlying mechanisms are scarce. AIMS The purpose of this study was to evaluate the incidence and prognostic factors for ATO within 1 week in TIPS recipients using ePTFE-covered stents. METHODS We identified 222 patients who underwent ePTFE-covered TIPS creation for complications of portal hypertension between June 2015 and June 2017 at a large tertiary center. Medical records and TIPS procedure data were retrospectively reviewed, and the influence of these variables on ATO was assessed by multivariate logistic regression analysis. RESULTS TIPS technical success was achieved in 219 patients (98.6%). Two patients were excluded due to missing data, leaving 217 patients for final analysis. ATO occurred in nine patients (4.1%). Blood flow was restored by balloon angioplasty (n = 4), additional stent insertion (n = 4), and parallel TIPS (n = 1). In multivariable logistic regression, intrastent stenosis (HR 43.871; 95% CI 3.816, 504.373; P = 0.002), previous splenectomy (HR 26.843; 95% CI 2.106, 342.124; P = 0.011), and stent shortening in the hepatic vein (HR 11.54; 95% CI 1.021, 130.416; P = 0.048) were demonstrated as independent significant risk factors for ATO. CONCLUSIONS These findings suggest that the intrastent stenosis, previous splenectomy, and stent shortening in the hepatic vein are vital prognostic factors for ATO in TIPS recipients. Individualized post-TIPS management strategy was required.

Abstract
BACKGROUND Evidence for the efficacy of TIPSS in ectopic variceal bleeding (EctVB) is largely based on relatively small series. AIM To define the efficacy of TIPSS in EctVB. METHODS Retrospective analysis of consecutive patients with chronic liver disease who presented with EctVB and received TIPSS in three tertiary centres in 1992-2016. RESULTS The study included 53 patients (70% male, median age 61 years, median model for end-stage liver disease (MELD) score 11). The ectopic varices were located around the insertion of stomas (40%), duodenum (23%), rectum (17%) and at other sites (20%). Three-quarters of the patients had previously received unsuccessful medical, endoscopic or surgical therapy. The median follow-up was 14.0 months. Following TIPSS, bleeding recurred in 12 patients: 6 of 12 (50%) with duodenal varices, 2 of 9 (22%) with rectal varices and one each with stomal (1/21), intraperitoneal (1/3), hepaticojejunostomy (1/2) and ascending colon varices (1/2). The risk factors for re-bleeding were MELD score at TIPSS placement (HR: 1.081 per point; 95% confidence interval (CI): 1.012-1.153; P = 0.034), varices located at site other than an enterostomy (HR: 9.770; 95%CI: 1.241-76.917; P = 0.030) and previous local therapy (HR: 5.710; 95%CI: 1.211-26.922; P = 0.028). The estimated cumulative re-bleeding rate was 23% at 1 year, 26% at 3 years and 32% at 5 years. Post-TIPSS hepatic encephalopathy manifested or worsened in 16 of 53 patients (30%). CONCLUSION TIPSS provides long-term control of bleeding in most cirrhotic patients with EctVB. TIPSS is particularly effective in stomal EctVB, the most frequent cause of EctVB, but might not be as effective in duodenal EctVB.

Abstract
Placement of transjugular intrahepatic portosystemic shunt (TIPS) is necessary in children with portal hypertension complicated by variceal bleeding or ascites. However, placement of adult-sized endografts may be problematic due to the smaller anatomy of pediatric patients. On the other hand, placement of fixed diameter smaller stents have the corresponding problem of not accommodating future growth of the child. We describe a novel method to create an adjustable diameter TIPS as a technical solution to these problems. In this technique, a balloon expandable bare metal stent is placed concentrically around the ePTFE TIPS endograft, creating an intentional narrowing in the shunt diameter than can be expanded with balloon dilation at future procedures as needed. This allows for optimal calibration of shunt hemodynamics according to the child's growth and prevents the potential need for placement of additional shunts or technically challenging TIPS reduction procedures.

Abstract
Variceal hemorrhage is a feared complication of portal hypertension, with high rates of morbidity and mortality. Optimal management requires a thoughtful, multidisciplinary approach. In cases of refractory or recurrent esophageal hemorrhage, endovascular approaches such as transjugular intrahepatic portosystemic shunt (TIPS) have a well-defined role. For hemorrhage related to gastric varices, the optimal treatment remains to be established; however, there is increasing adoption of balloon-occluded retrograde transvenous obliteration (BRTO). This article will review the concept, history, patient selection, basic technique, and outcomes for TIPS, BRTO, and combined TIPS + BRTO procedures for variceal hemorrhage.

Timing Affects Measurement of Portal Pressure Gradient After Placement of Transjugular Intrahepatic Portosystemic Shunts in Patients With Portal Hypertension. Gastroenterology 2017; 152:1358-1365.

Abstract
BACKGROUND & AIMS A reduction in portal pressure gradient (PPG) to <12 mm Hg after placement of a transjugular intrahepatic portosystemic shunt (TIPS) correlates with the absence of further bleeding or ascites at follow-up examinations of patients with cirrhosis. The PPG is usually measured immediately after placement of the TIPS, when different circumstances can affect PPG values, which could affect determination of risk for decompensation. We investigated variations in PPG measurements collected at different time points after TIPS, aiming to identify a time point after which PPG values were best maintained. METHODS We performed a retrospective study of 155 consecutive patients with severe complications of portal hypertension who received placement of TIPS from January 2008 through October 2015; patients were followed until March 2016. We compared PPG values measured at different time points and under different conditions: immediately after placement of TIPS (immediate PPG); at least 24 hours after placement to TIPS into hemodynamically stable patients, without sedation (early PPG); and again 1 month after TIPS placement (late PPG). RESULTS The immediate PPG differed significantly from the early PPG, regardless of whether the TIPS was placed using general anesthesia (8.5 ± 3.5 mm Hg vs 10 ± 3.5 mm Hg; P = .015) or deep sedation (12 ± 4 mm Hg vs 10.5 ± 4 mm Hg; P <.001). In considering the 12 mm Hg threshold, concordance between immediate PPG and early PPG values was poor. However, there was no significant difference between mean early PPG and late PPG values (8.5 ± 2.5 mm Hg vs 8 ± 3 mm Hg), or between proportions of patients with early PPG vs late PPG values <12 mm Hg threshold. Maintenance of a PPG value <12 mm Hg during the follow-up period was associated with a lower risk of recurrent or de novo variceal bleeding or ascites (hazard ratio, 0.11; 95% confidence interval, 0.04 0.27; P < .001). CONCLUSIONS In a retrospective study of patients with PPG values measured at different time points after TIPS placement, we found measurements of PPG in awake, hemodynamically stable patients at least 24 hours after TIPS to be the best maintained values. Our findings support the concept that PPG value <12 mm Hg after TIPS placement is associated with reduced risk of bleeding and ascites.

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

Abstract
PURPOSE The purpose of this study was to evaluate the short- and long-term evolution of endoluminal diameter of covered metallic stents that were underdilated at the time of transjugular intrahepatic portosystemic shunt (TIPS) creation. MATERIEL AND METHODS Sixteen patients (13 men, 3 women) with a mean age of 57.6years±7.9 (SD) were retrospectively included. All patients had had TIPS creation using a 10-mm diameter covered stent (VIATORR®) that was underdilated (i.e., 8mm) at the time of stent placement. Measurements of the mean circulating diameter of the stents were retrospectively performed on angiographic examinations every 6months up to 2years. RESULTS The endoluminal stent diameter early enlarged from 8.96mm±1.12 (SD) to 10mm±1.45 (SD) after 6months (P=0.04) with no further significant changes over time after 12months (10.28mm±1.9mm), 18months (9.93±1.51mm) and 24months (9.92±0.9mm). CONCLUSION Our results demonstrate a passive expansion of initially underdilated covered stents during the six months following TIPS creation. This should be taken into account regarding hepatic encephalopathy prevention during TIPS placement.
