Trans-splenic Approach for Transjugular Intrahepatic Portosystemic Shunt (TIPS) Creation in Patients with Portal Vein Thrombosis

Meta-analysis of transjugular intrahepatic portosystemic shunt creation with intravascular ultrasound guidance.

To conduct a meta-analysis to assess the efficacy of intravascular ultrasound (IVUS) during transjugular intrahepatic portosystemic shunt (TIPS) creation. MEDLINE and Embase databases were queried until July 2022 for comparative studies reporting procedure metrics for TIPS creation with or without IVUS guidance. Meta-analysis was performed with random-effects modeling for total procedural time, time to portal venous access, fluoroscopy time, iodinated contrast volume use, air kerma, dose area product, and number of needle passes. Intraoperative procedure-related complications were also reviewed. Of 95 unique records initially identified, 6 were eligible for inclusion. A total of 194 and 240 patients underwent TIPS with and without IVUS guidance. Pooled analyses indicated that IVUS guidance was associated with reduced total procedure time (SMD -0.76 [95% CI -1.02, -0.50] P < 0.001), time to portal venous access (SMD -0.41 [95% CI -0.67, -0.15] P = 0.002), fluoroscopy time (SMD, -0.54 [95% CI -1.02, -0.07]; P = 0.002), contrast volume use (SMD, -0.89 [95% CI -1.16, -0.63]; P < 0.001), air kerma (SMD, -0.75 [95% CI -1.11, -0.38]; P < 0.001) and dose area product (SMD, -0.98 [95% CI -1.77, -0.20]; P = 0.013). 4.2 and 7.8 needle passes were required in the IVUS and non-IVUS group, respectively (SMD, -0.60 [95% CI -1.42, 0.21]; P = 0.134), whereas pooled complication rates were 15.2% (12/79), and 21.4% (28/131), respectively. IVUS guidance during TIPS creation improves procedural metrics including procedural time, contrast usage, and radiation exposure.

CBCT-based three-dimensional dual-phase vascular image fusion: anovel technique for interventional real-time TIPS guidance.

Due to the invisibility of the portal vein (PV), how to puncture the PV accurately and safely in transjugular intrahepatic portosystemic shunt (TIPS) creation remains achallenge of the procedure. We aimed to provide the first evaluation of the safety, feasibility, and efficiency of cone beam computed tomography (CBCT)-based three-dimensional (3D) dual-phase vascular image fusion for interventional real-time guided PV puncture during TIPS procedures. From January 2021 to May 2021, 13patients undergoing TIPS were prospectively enrolled in this study. Images of the hepatic artery (HA) and PV in 3D were acquired and overlaid on interventional fluoroscopy images in adual-phase display mode for real-time PV puncture guidance. The number of PV puncture attempts, puncture time, overlaid image accuracy, dose area product, fluoroscopy time, and interventional complications were recorded. Portal vein puncture guided by CBCT-based 3D dual-phase vascular image fusion was successfully performed on 92.3% (12/13) patients. The mean number of PV puncture attempts was 1.8 ± 0.7 (1-3). The mean puncture time and fluoroscopy time was 3.5 ± 1.2 (2-6) min and 25.1 ± 9.4 (15-45) min, respectively. The mean dose area product was 39.49 ± 7.88 (28.81-52.87) mGym2. The error between the reference position of the fusion image and the interventional PV angiography image was less than 0.5 cm. No interventional complication was observed. Our results show that 3D dual-phase vascular image fusion might be asafe and feasible technique for interventional real-time guided PV puncture during TIPS. This novel technique might help to reduce the number of PV puncture attempts and the puncture time as well as lower the risks of interventional complications.

Transjugular Intrahepatic Portosystemic Shunt (TIPS) Extension for Transhepatic Mesocaval Shunt Creation: A Case Series for Treating Refractory Upper Gastrointestinal Bleeding in Patients with Chronic Portal Vein Thrombosis.

Transjugular intrahepatic portosystemic shunt (TIPS) is known to benefit patients with decompensated liver disease by alleviating portal pressure. However, TIPS creation is technically difficult and challenging to perform in patients with chronic portal vein thrombosis (PVT) (4,5). Multiple endovascular techniques for portal vein recanalization with or without creating portosystemic shunt are available to decompress and alleviate portal hypertension in patients with PVT. In this case series, we represent TIPS extension to create an endovascular mesocaval shunt for the treatment of refractory upper gastrointestinal bleeding.

Emergent TIPS for acute gastroesophageal variceal bleeding in cirrhotic patients with hepatocellular carcinoma.

To estimate the safety and effectiveness of emergent transjugular intrahepatic portosystemic shunt (TIPS) creation for acute variceal bleeding (AVB) in cirrhotic patients with hepatocellular carcinoma (HCC). Data of thirty-three patients with AVB and HCC undergoing emergent TIPS creation from January 2016 to January 2022 were enrolled and were retrospectively analyzed. The primary outcomes were the safety of emergent TIPS creation, the bleeding control rate, and the rebleeding rate. The secondary outcomes included overall survival (OS), liver function, overt hepatic encephalopathy (HE), and shunt dysfunction. Emergent TIPS creation was technically successful in 33 patients (100%) and one (3.0%) patient suffered a major procedure-related adverse event. The control rate of bleeding (within 5days) was 100%. During a median follow-up period of 26.3months, rebleeding occurred in 6 (18.2%) patients. The median OS was 20.0months. The 6-week and 1-year survival rates were 87% and 65%, respectively. Laboratory tests showed no significant impairment of liver function following TIPS creation. The incidences of overt HE and shunt dysfunction were 24.2% and 6.1%, respectively. Emergent TIPS creation is feasible and effective for treatment of AVB in cirrhotic patients with HCC.

Intravascular Ultrasound Guidance for Transjugular Intrahepatic Portosystemic Shunt Creation Reduces Laboratory Markers of Acute Liver Injury

PurposeTo compare the laboratory markers of acute liver injury after transjugular intrahepatic portosystemic shunt (TIPS) creation performed using intravascular ultrasound (IVUS) guidance with those using other techniques. Materials and MethodsThis single-center, retrospective study examined 293 TIPS procedures performed between 2014 and 2022 (160 men; mean age, 57.4 years; 71.7% with ascites, 158 with IVUS). Laboratory changes on postprocedural day (PPD) 1 were classified based on Common Terminology Criteria for Adverse Events (CTCAE) grades and were compared between IVUS and non-IVUS cases. ResultsIVUS cases had a lower baseline Model for End-Stage Liver Disease (MELD) score (12.5 vs 13.7, P = .016), higher pre- (16.8 vs 15.2, P = .009), and post-TIPS (6.6 vs 5.4 mm Hg, P < .001) pressure gradient, smaller stent diameter (9.2 vs 9.9 mm, P < .001), and fewer needle passes (2.4 vs 4.2, P < .001). IVUS predicted a lower PPD 1 CTCAE grade for aspartate transaminase (8.0% vs 22.2% grade ≥ 2, P = .010), alanine transaminase (ALT) (2.2% vs 7.1%, P = .017), and bilirubin (9.4% vs 26.2%, P < .001), findings confirmed using multivariable regression and propensity score analysis. IVUS predicted fewer adverse events (1.3% vs 8.1%, P = .008) and an increased likelihood of PPD 1 discharge (81% vs 59%, P = .004). IVUS was not associated with differences in PPD 30 MELD scores or 30-day survival; however, higher PPD 1 ALT (β = 1.96, P = .008) and bilirubin levels (β = 1.38, P = .004) predicted larger PPD 30 MELD score increase. Higher increases in ALT level predicted worse 30-day survival (hazard ratio, 1.93; P = .021). ConclusionIVUS resulted in less laboratory evidence of acute liver injury immediately following TIPS creation.

Feasibility of computed tomography portal venography in the preoperative evaluation of emergent TIPS creation for cirrhotic patients with acute variceal bleeding

ObjectivesTo evaluate the feasibility of computed tomography portal venography (CTPV) in the preoperative evaluation of emergent transjugular intrahepatic portosystemic shunt (TIPS) creation for cirrhotic patients with acute variceal bleeding (AVB). MethodsOne hundred and forty-eightcirrhotic patients with AVB undergoing emergent TIPS creation from January 2016 to December 2022 in our institution were enrolled in the retrospective study. The primary outcome was the consistency between CTPV and endoscopy in the classification and grading of gastroesophageal varices (GEVs). The second outcome was extraluminal CTPV findings. The consistency of CTPV and endoscopy in the classification and grading of GEVs was determined by Kappa values. ResultsEmergent TIPS creation was technically successful in all patients. Forty-five patients underwent preoperative endoscopy. The results of CTPV diagnosis of GEVs classification were that 112, 28, and 8 patients were classified as gastroesophageal varices type 1 (GOV1), GOV2, and isolated gastric varices type 1 (IGV1), respectively. In diagnosing the classification and grading of GEVs, CTPV showed substantial agreement with preoperative endoscopy, with Kappa values of 0.823 and 0.625, respectively. CTPV provided the afferent and afferent vessels of GEVs for emergent TIPS creation. ConclusionCTPV is feasible and effective to act as an alternative preoperative evaluation method to endoscopy for cirrhotic patients with AVB undergoing emergent TIPS creation.

Transjugular intrahepatic portosystemic shunt creation (TIPS) in the angio-CT—a hybrid intervention with image fusion

ObjectiveFor transjugular intrahepatic portosystemic shunt (TIPS) creation, ultrasound guidance for portal vein puncture is strongly recommended. However, outside regular hours of service, a skilled sonographer might be lacking. Hybrid intervention suites combine CT imaging with conventional angiography allowing to project 3D information into the conventional 2D imaging and further CT-fluoroscopic puncture of the portal vein. The purpose of this study was to assess whether TIPS using angio-CT facilitates the procedure for a single interventional radiologist.MethodsAll TIPS procedures from 2021 and 2022 which took place outside regular working hours were included (n = 20). Ten TIPS procedures were performed with just fluoroscopy guidance and ten procedures using angio-CT. For the angio-CT TIPS, a contrast-enhanced CT was performed on the angiography table. From the CT, a 3D volume was created using virtual rendering technique (VRT). The VRT was blended with the conventional angiography image onto the live monitor and used as guidance for the TIPS needle. Fluoroscopy time, area dose product, and interventional time were assessed.ResultsHybrid intervention with angio-CT did lead to a significantly shorter fluoroscopy time and interventional time (p = 0.034 for both). Mean radiation exposure was significantly reduced, too (p = 0.04). Furthermore, the mortality rate was lower in patients who underwent the hybrid TIPS (0% vs 33%).ConclusionTIPS procedure in angio-CT performed by only one interventional radiologist is quicker and reduces radiation exposure for the interventionalist compared to mere fluoroscopy guidance. The results further indicate increased safety using angio-CT.Clinical relevance statementThis study aimed to evaluate the feasibility of using angio-CT in TIPS procedures during non-standard working hours. Results indicated that the use of angio-CT significantly reduced fluoroscopy time, interventional time, and radiation exposure, while also leading to improved patient outcomes.Key Points• Image guiding such as ultrasound is recommended for transjugular intrahepatic portosystemic shunt creation but might be not available for emergency cases outside of regular working hours.• Transjugular intrahepatic portosystemic shunt creation using an angio-CT with image fusion is feasible for only one physician under emergency settings and results in lower radiation exposure and faster procedures.• Transjugular intrahepatic portosystemic shunt creation using an angio-CT with image fusion seems to be safer than using mere fluoroscopy guidance.

Change in Platelet Count after Transjugular Intrahepatic Portosystemic Shunt Creation: An Advancing Liver Therapeutic Approaches (ALTA) Group Study

PurposeTo evaluate recovery of platelet count after transjugular intrahepatic portosystemic shunt (TIPS) creation and patient factors predicting platelet recovery after TIPS creation. Materials and MethodsAdults with cirrhosis who underwent TIPS creation at 9 U.S. hospitals from 2010 to 2015 were included in this retrospective analysis. Change in platelets from before TIPS to 4 months after TIPS creation was characterized. Logistic regression was used to assess factors associated with top quartile percentage platelet increase after TIPS. Subgroup analyses were performed among patients with a pre-TIPS platelet count of ≤50 ×109/L. ResultsA total of 601 patients were included. The median absolute change in platelets was 1 × 109/L (−26 × 109/L to 25 × 109/L). Patients with top quartile percent platelet increase experienced ≥32% platelet increase. In multivariable analysis, pre-TIPS platelet counts (odds ratio [OR], 0.97 per 109/L; 95% CI, 0.97–0.98), age (OR, 1.24 per 5 years; 95% CI, 1.10–1.39), and pre-TIPS model for end-stage liver disease (MELD) scores (OR, 1.06 per point; 95% CI, 1.02–1.09) were associated with top quartile (≥32%) platelet increase. Ninety-four (16%) patients had a platelet count of ≤50 × 109/L before TIPS. The median absolute platelet change was 14 × 109/L (2 × 109/L to 34 × 109/L). Fifty-four percent of patients in this subgroup were in the top quartile for platelet increase. In multivariable logistic regression, age (OR, 1.50 per 5 years; 95% CI, 1.11–2.02) was the only factor associated with top quartile platelet increase in this subgroup. ConclusionsTIPS creation did not result in significant platelet increase, except among patients with a platelet count of ≤50 × 109/L before TIPS. Lower pre-TIPS platelet counts, older age, and higher pre-TIPS MELD scores were associated with top quartile (≥32%) platelet increase in the entire cohort, whereas only older age was associated with this outcome in the patient subset with a pre-TIPS platelet count of ≤50 × 109/L.

Safety and feasibility of a novel bi-directional portal vein access kit during transjugular intrahepatic portosystemic shunt creation

BackgroundTransjugular intrahepatic portosystemic shunt (TIPS) creation remains as one of the more technically challenging endovascular procedures. Portal vein access from the hepatic vein often requires multiple needle passes, which increases procedure times, risk of complications, and radiation exposure. With its bi-directional maneuverability, the Scorpion X access kit may be a promising tool for easier portal vein access. However, the clinical safety and feasibility of this access kit has yet to be determined.Materials and methodsIn this retrospective study, 17 patients (12 male, average age 56.6 ± 9.01) underwent TIPS procedure using Scorpion X portal vein access kits. The primary endpoint was time taken to access the portal vein from the hepatic vein. The most common indications for TIPS were refractory ascites (47.1%) and esophageal varices (17.6%). Radiation exposure, total number of needle passes, and intraoperative complications were recorded. Average MELD Score was 12.6 ± 3.39 (range: 8–20).ResultsPortal vein cannulation was successfully achieved in 100% of patients during intracardiac echocardiography-assisted TIPS creation. Total fluoroscopy time was 39.31 ± 17.97 min; average radiation dose was 1036.76 ± 644.15 mGy, while average contrast dose was 120.59 ± 56.87 mL. The average number of passes from the hepatic vein to the portal vein was 2 (range: 1–6). Average time to access the portal vein once the TIPS cannula was positioned in the hepatic vein was 30.65 ± 18.64 min. There were no intraoperative complications.ConclusionsClinical utilization of the Scorpion X bi-directional portal vein access kit is both safe and feasible. Utilizing this bi-directional access kit resulted in successful portal vein access with minimal intraoperative complications.Level of evidenceRetrospective cohort.

Intravascular Ultrasound for Transjugular Intrahepatic Portosystemic Shunt Creation: "TIPS" and Tricks.

Cirrhosis affects 4.5 million people in the United States.[1] Sequela of cirrhosis and portal hypertension include varices, which occur in up to 60 to 80% of cirrhotic patients and pose a bleeding risk of 25 to 35%[2]; refractory ascites, which occurs in 5 to 10% of patients[3]; recurrent hepatic hydrothorax, which occurs in 5 to 10% of cirrhotic patients[4]; and hepatic encephalopathy, which occurs in up to 45% of patients with cirrhosis.[5] Transjugular intrahepatic portosystemic shunt (TIPS) creation results in portal venous decompression and reduces mortality and morbidity associated with these portal hypertensive sequelae. There is a clear survival benefit with TIPS creation in patients at risk of variceal hemorrhage, including those who fail endoscopic banding, who are at high risk of pharmacologic or endoscopic treatment failure,[6] and who undergo early TIPS creation for secondary prophylaxis against bleeding.[7] [8] For those with refractory ascites and hepatic hydrothorax, resolution of fluid accumulation can be expected in 85%[9] and 82%, respectively.[10]

Impact of General Anesthesia on the Right Atrial Pressure During Transjugular Intrahepatic Portosystemic Shunt Creation: A Propensity Score Match Analysis.

To evaluate the effect of general anesthesia on right atrial (RA) pressure measurements during transjugular intrahepatic portosystemic shunt (TIPS) placement using propensity score match analysis. A single-institution database was used to identify 664 patients who underwent TIPS creation under either conscious sedation (CS) or general anesthesia (GA) between 2009 and 2018. A propensity-matched cohort was created using logistic regression of sedation method on demographics, liver disease status, and indications. Paired analyses were performed using mixed models for RA pressure and Cox proportional hazards model with robust standard errors for mortality. Of the 664 patients, 270 patients were matched based on similar characteristics (135 for GA and 135 for CS). Indications for TIPS creation included intractable ascites (n = 170, 63%), hepatic hydrothorax (n = 30, 11%), variceal bleeding (n = 43, 16%), and other (n = 27, 10%). Pre-TIPS RA pressure was greater in the matched GA group as compared to CS group by a mean of 4.2mmHg (p < 0.0001). Similarly, post-TIPS RA pressure was greater in the matched GA group as compared to CS group by a mean of 3.3mmHg (p < 0.0001). Pre- and post-procedure RA pressure was found to have no association with post-procedure mortality (0.8891, HR 1.077; p 0.917, HR 0.997; respectively). Utilization of GA during TIPS creation raises the intra-procedural RA pressure compared to CS. However, this elevated intra-procedural RA pressure does not appear to be predictive of mortality post-TIPS creation.

Comparing the predictive ability of portoatrial and portocaval gradient after transjugular intrahepatic portosystemic shunt creation for variceal rebleeding.

Measuring the portal pressure gradient from the portal vein (PV) to the inferior vena cava (IVC) or to the right atrium (RA) remains controversial. The aim of our study was to compare the predictive ability of portoatrial gradient (PAG) and portocaval gradient (PCG) for variceal rebleeding. The data of 285 cirrhotic patients with variceal bleeding undergoing elective transjugular intrahepatic portosystemic shunt (TIPS) in our hospital were analyzed retrospectively. The variceal rebleeding rates were compared between groups categorized by established or modified thresholds. The median follow-up time was 30.0months. After TIPS, PAG was equal to (n = 115) or more than (n = 170) PCG. The pressure of IVC was defined as an independent predictor for a PAG-PCG difference of ≥ 2mmHg (p < 0.001, OR 1.23, 95% CI 1.10-1.37). Using a threshold of 12mmHg, PAG (p = 0.081, HR 0.63, 95% CI 0.37-1.06) could not predict variceal rebleeding but PCG could (p = 0.003, HR 0.45, 95% CI 0.26-0.77). This pattern was unchanged when a ≥ 50% reduction from baseline was also considered as a threshold (PAG/PCG: p = 0.114 and 0.001). Subgroup analyses showed that only in patients with post-TIPS IVC pressure < 9mmHg (p = 0.018), PAG could predict variceal rebleeding. Because PAG was on average 1.4mmHg higher than PCG, patients were classified by a PAG of 14mmHg, and there was no difference in rebleeding rates between these two groups (p = 0.574). For patients with variceal bleeding, the predictive ability of PAG is limited. The portal pressure gradient should be measured between the PV and IVC.

Transjugular Intrahepatic Portosystemic Shunt Creation in Children Weighing

Transjugular intrahepatic portosystemic shunt (TIPS) creation is a standard therapeutic procedure for the management of complications of portal hypertension. However, in small children, this procedure is infrequently performed because of technical difficulties owing to their small size and scarce information on outcomes. This article presents the results of treatment of variceal bleeding with TIPS creation in 8 children weighing <10 kg, along with the description of the unconventional techniques and materials required. Technical and clinical success rates were 100%. Although this was a small cohort of patients, the results obtained suggest that this is a safe and technically and clinically effective treatment option for complications of portal hypertension in this age group.

Hepatic Encephalopathy after Transjugular Intrahepatic Portosystemic Shunt Creation.

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.
