ABSTRACT
OBJECTIVES: Salvage TIPS is indicated in patients with active endoscopically uncontrollable variceal bleeding. TIPS alone is not effective in management of gastric varices and BRTO requires favourable variceal anatomy. Concomittant placement of a TIPS stent with antegrade variceal embolisation leads to control of gastric variceal bleeding with no significant increase in portal pressure. MATERIALS AND METHODS: A single centre retrospective observational study where patients with active uncontrollable gastric variceal bleeding were included in the study. Technical success of the procedure, 5-day rebleed, 6-weeks and 6-months survival as well as other additional outcomes were evaluated. RESULTS: A total of 18 patients were included in the study. Technical success was 100% and significant non-target embolisation was seen in 0% patients. 6 week and 6 month survival rates were 66.67% with an overall survival of 108.786 days (censored at 180 days). 5 day rebleed rate was 11.1%. A significant difference in CTP score (p = 0.03), MELD Na score (p = 0.022), requirement of intubation (p = 0.038), hemoglobin levels (p = 0.042), hematocrit value (p = 0.018), PRBC infusion required prior to and after the procedure (p = 0.045, 0.044) and presence of refractory shock (p = 0.013) was observed between the survival and the mortality group. Post variceal bleeding hemoglobin levels, MAP and MELD-Na scores were significant predictors of mortality. CONCLUSION: TIPS in adjunct to antegrade transvenous embolisation is a safe and effective modality for management of active uncontrolled gastric variceal bleeding in patients with variceal anatomy unfavourable for performing RTO.
ABSTRACT
Background/Aims: To study the association of infertility in patients with Budd Chiari syndrome, radiological aspects of the disease determining infertility and to see if there are improved chances of conception following radiological intervention. Methods: Retrospective search of the hospital records was done and patients with Budd Chiari syndrome, who underwent radiological intervention between January 2016 till October 2021 were initially included. Patients outside the reproductive age group, unmarried patients, patients who did not attempt conception or attempted for less than 1 year and patients having other causes of infertility were excluded. 90 patients were assessed for presence of primary or secondary infertility using infertility questionnaire. In patients with infertility, conception during 1-year follow-up period following radiological intervention, was assessed. Results: 146 patients underwent radiological intervention for Budd Chiari syndrome in the study period. 56 patients meeting the exclusion criteria were excluded from the study and subsequently 90 patients were assessed for infertility. 16.7% (15/90) of our patients with Budd Chiari syndrome had infertility, of which 7 were male, and 8 were female. Infertility is more common in younger age group (mean - 28.8 ± 4.2 years) (P < 0.001). In females, presence of pelvic venous congestion on preprocedural imaging showed significant association with infertility (P < 0.001). 6 (40%) out of 15 of patients with infertility conceived during a 1-year follow-up period after radiological intervention. Conclusion: Infertility is a common in patients with Budd Chiari syndrome, with a prevalence of 16.7%. Pelvic venous congestion is associated with women having infertility. Radiological interventions play important role in management of Budd Chiari and may help to overcome infertility in these patients.
ABSTRACT
BACKGROUND: Meso-Rex bypass is the surgical intervention of choice for children with extrahepatic portal vein obstruction (EHPVO). Patency of Rex vein, umbilical recessus of the portal vein, is a prerequisite for this surgery. Conventional diagnostic modalities poorly detect patency, while transjugular wedged hepatic vein portography (WHVP) accurately detects patency in 90%. OBJECTIVES: We aimed to assess Rex vein patency and portal vein branching pattern in children with EHPVO using transjugular WHVP and to identify factors associated with Rex vein patency. METHODS: Transjugular WHVP was performed in 31 children with EHPVO by selective cannulation of left and right hepatic veins. Rex vein patency, type of intrahepatic portal venous anatomy (Types A-E), and factors associated with patency of Rex vein were studied. RESULTS: The patency of Rex recess on transjugular WHVP was 29%. Complete obliteration of intrahepatic portal venous radicles was the commonest pattern (Type E, 38.7%) while Type A, the favorable anatomy for meso-Rex bypass, was seen in only 12.9%. Patency of the Rex vein, but not the anatomical pattern, was associated with younger age at evaluation (patent Rex: 6.6 ± 4.9 years vs. nonpatent Rex: 12.7 ± 3.9 years, p = 0.001). Under-5-year children had a 12 times greater chance of having a patent Rex vein (odds ratio: 12.22, 95% confidence interval: 1.65-90.40, p = 0.004). Patency or pattern was unrelated to local factors like umbilical vein catheterization, systemic thrombophilia, or disease severity. CONCLUSION: Less than one-third of our pediatric EHPVO patients have a patent Rex vein. Younger age at evaluation is significantly associated with Rex vein patency.

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.
ABSTRACT
BACKGROUND: Post-transjugular intrahepatic portosystemic shunt (TIPS) liver failure (PTLF) is a serious complication of TIPS procedure with poor patient prognosis. This study tried to investigate the incidence of PTLF following elective TIPS procedure and evaluated possible predictive factors for the same. METHODS: A retrospective analysis of patients who underwent elective TIPS placement between 2012 and 2022 and was conducted to determine development of PTLF (≥ 3-fold bilirubin and/or ≥ 2-fold INR elevation from the baseline) within 30 days following TIPS procedure. Medical record review was done and factors predicting development of PTLF and the 90-day transplant-free survival was determined. RESULTS: Thirty of 352 (8.5%) patients developed PTLF within 30 days of TIPS (mean age 54.2 ± 9.8 years, 83% male). The etiology of cirrhosis was related to non-alcoholic steatohepatitis (NASH) in 50%, alcohol in 33.3%, and hepatitis B/C virus infection in 16.7% of the patients. The mean Child-Turcotte-Pugh (CTP) score was 9.5 ± 1.2 and mean model for end stage liver disease (MELD) score was 14.6 ± 4.5 at the time of admission in patients who developed PTLF. The indication for TIPS was recurrent variceal bleed in 50% (15 of 30) and refractory ascites in 46.7% (14 of 30) patients with PTLF. Multivariate analysis identified prior HE (OR 6.1; CI 2.57-14.5, p < 0.0001) and higher baseline CTP score (OR 1.47; CI 1.07-2.04; p = 0.018) as predictors of PTLF. PTLF was associated with significantly lower 90-day transplant-free survival, as compared to patients without PTLF (40% versus 96%, p < 0.001). CONCLUSION: Almost 10% of patients with cirrhosis develop post-TIPS liver failure and is associated with significant early mortality and morbidity. Higher baseline CTP score and prior HE were identified as predictors for PTLF.

Gastrointestinal hemorrhage remains one of the most common causes of morbidity and mortality among patients with liver cirrhosis. Mostly, these patients bleed from the gastroesophageal varices. However, nonvariceal bleeding is also more likely to occur in these patients. Because of frequent co-existing coagulopathy, cirrhotics are more prone to bleed from a minor vascular injury while performing percutaneous interventions. Ultrasound-guided bedside vascular access is an essential procedure in liver critical care units. Transjugular portosystemic shunts (TIPS) with/without variceal embolization is a life-saving measure in patients with refractory variceal bleeding. Whenever feasible, balloon-assisted retrograde transvenous obliteration (BRTO) is an alternative to TIPS in managing gastric variceal bleeding, but without a risk of hepatic encephalopathy. In cases of failed or unfeasible endotherapy, transarterial embolization using various embolic agents remains the cornerstone therapy in patients with nonvariceal bleeding such as ruptured hepatocellular carcinoma, gastroduodenal ulcer bleeding, and procedure-related hemorrhagic complications. Among various embolic agents, N-butyl cyanoacrylate (NBCA) enables better vascular occlusion in cirrhotics, even in coagulopathy, making it a more suitable embolic agent in an expert hand. This article briefly entails the different interventional radiological procedures in vascular emergencies among patients with liver cirrhosis.

Objectives The objective of the study was to identify accurate site of liver biopsy under ultrasound and elastography guidance and compare the shear wave elastography (SWE) and transient elastography (TE) diagnostic accuracy with histopathological correlation. Methods This was a prospective single-center study where patients scheduled for nonfocal liver biopsy were divided into two groups (group U: ultrasound; group E elastography) by sequential nonrandom selection of patients. Elastography was performed before the biopsy and biopsies from the maximum stiffness segment were taken. Results There was no significant difference of intersegmental liver stiffness with mean velocity; however, biopsy segment velocities show significant difference with mean liver stiffness suggestive of heterogenous distribution of fibrosis. The rho ( r ; Spearman's correlation) value between biopsy segments and mean velocities shows excellent correlation. The diagnostic performance of TE was good for fibrosis stages F2, F3, and F4, while SWE was fair for the diagnosis of fibrosis stages F1 and F2 and fairly equal for the diagnosis stages F2 and F3. Area under the curve (AUC) values in differentiating mild (F1) or no fibrosis from significant fibrosis (≥F2) were 95.5 with cutoff value of at least 1.94 m/s. Conclusions The diagnostic performance of SWE is comparable with TE in liver fibrosis staging and monitoring. Fibrosis is heterogeneously distributed in different segments of the right lobe liver. Therefore, elastography at the time of biopsy may help in defining the accurate site for biopsy and improve histopathological yield in detecting liver fibrosis in patients with chronic liver disease. Advances in Knowledge Elastography-guided biopsy is helpful to determine the ideal site of biopsy.
ABSTRACT
Objectives Direct intrahepatic portosystemic shunt (DIPS) stent placement is an effective treatment for patients with Budd-Chiari syndrome (BCS); however, thrombotic occlusion of DIPS stent remains a cause of concern. The purpose of this study is to describe a novel technique of balloon-occluded-thrombolysis (BOT) for occluded DIPS stent, and compare it with the conventional catheter-directed-thrombolysis (CDT). Methods In this retrospective study, the hospital database was searched for BCS patients who underwent DIPS revision for thrombotic stent occlusion between January 2015 and February 2021. Patients were divided into CDT group and BOT group. The groups were compared for technical success, total dose of thrombolytic agent administered, duration of hospital stay, and primary assisted stent patency rates at 1- and 6-month follow-up. Results CDT was performed in 12 patients, whereas 21 patients underwent BOT. Complete recanalization was achieved in 66.7% (8 of 12) patients of CDT group as compared to 81% (17 of 21) patients of BOT group (nonsignificant difference, p = 0.420). BOT group had a short hospital stay (1.8 ± 0.7 vs. 3.5 ± 1.0 days) and required less dose of thrombolytic agent ([2.2 ± 0.4]x10 5 IU versus [8.3 ± 2.9]x10 5 IU of urokinase) as compared to the CDT group and both differences were statistically significant ( p < 0.001). Further, 6-month patency rate was higher in BOT group as compared to CDT group ( p = 0.024). Conclusion The novel BOT technique of DIPS revision allows longer contact time of thrombolytic agent with the thrombi within the occluded stent. This helps in achieving fast recanalization of thrombosed DIPS stent with a significantly less dose of thrombolytic agent required, thus reducing the risk of systemic complications associated with thrombolytic administration.
ABSTRACT
Background: Combined hepatocellular-cholangiocarcinoma (cHCC-CCA) is an uncommon form of primary liver carcinoma. It is heterogenous in terms of morphology, immunohistochemistry, radiology, and clinical features; making it a challenging entity for diagnosis. Aims: The purpose of the present study was to evaluate clinicopathological characteristics of patients with cHCC-CCA. Settings and Design: Retrospective observational study. Materials and Methods: The patients diagnosed with cHCC-CC were identified from hepatic surgical specimens and were evaluated. Statistical Analysis: Survival was estimated as per Kaplan-Meier method. Results: Out of six patients, five had undergone resection while one had liver transplant. Five were male and one was female and the mean age was 52 years. Tumor markers revealed raised serum alfa-fetoprotein and CA19.9 in four and three patients, respectively. Five of the liver specimens were cirrhotic. Diagnosis was predominantly based on tumor morphology. All cases were of Allen and Lisa type B and cHCC-CCA as per WHO (2019) classification. Stem cell features <5% were noted in two cases. Immunohistochemistry for programmed death 1/programmed death ligand 1 (PD1/PDL1) was negative in both the hepatocellular and cholangiocellular components in all six cases. Mismatch repair (MMR) protein expression was retained in two and deficient in four cases. The median follow-up after surgery was 21.3 months (range, 5-46.2 months). Five patients had intrahepatic and/or extrahepatic recurrence on follow-up after surgery. The median recurrence-free survival was estimated at 13.1 months (95% CI 5.67-20.6). Three patients had received salvage treatment. The median overall survival was estimated at 20 months (95% CI 0-45.3). Conclusions: The present study highlights the role of morphology in the diagnosis of cHCC-CCA. The choice of locoregional and/or systemic therapy after surgery may be individualized based on the clinicopathological characteristics.

Introduction: This article aims to evaluate the prognostic significance of pretreatment serum ɣ-glutamyl transpeptidase (GGT) levels in patients with intermediate (BCLC B) and advanced stage (BCLC C) hepatocellular carcinoma receiving transarterial chemoembolization (TACE) as first-line treatment. Methods: In this single-center retrospective study, a total of 608 patients with BCLC B and BCLC C class were included who received TACE as first-line treatment modality. Patients were divided into low and high GGT groups based on a cutoff value of pretreatment serum GGT levels calculated by receiver operating curve. Overall survival was evaluated with Kaplan-Meier method, and intergroup significance was calculated by log-rank test for overall patients, each BCLC B and BCLC C group. Univariate and multivariate analysis were used for significance for prognostic factors. Results: Median follow-up time was 20, 22, and 9 months for overall patients, BCLC B, and BCLC C group, respectively. Optimal cut value for GGT was calculated at 90.5 U/L. One-year and 3-year survival rates were 84.2% and 27.9% in low GGT, 49.4% and 8.6% in high-GGT group for overall patients. Multivariate analysis in overall patients showed Child-Pugh B (HR,1.801; 95%CI, 1.373-2.362, P < .001), ascites (1.393, 1.070-1.812; P = .014), multiple tumors (1.397, 1.137-1.716; P = .001), AST >40 (1.407, 1.095-1.808; P = .008), albumin <3.2 (.735, .612-.884; P = .001), AFP > 400 (1.648, 1.351-2.011; P < .001), high GGT (2.009, 1.631-2.475; P < .001), or receipt of chemo/ablation (.463, .377-.569; P < .001) as independent risk factors for overall survival. Serum GGT levels and AFP showed significant correlation in between with significance coefficient of .155 (P < .001). Conclusion: Elevated pretreatment serum GGT level was feasible and promising independent prognostic marker for overall survival in intermediate and advanced stage hepatocellular carcinoma patients treated with TACE.
ABSTRACT
Liver transplantation is the treatment of choice in majority of the patients with end stage liver disease. Vascular complication following liver transplantation is seen in around 7-13% of the patients and is associated with graft dysfunction and high morbidity and mortality. Early diagnosis and prompt treatment are crucial in management of these patients. Advances in interventional radiology have significantly improved the management of vascular complications using minimally invasive percutaneous approach. Endovascular management is preferred in patients with late hepatic artery thrombosis, or stenosis, whereas retransplantation, surgical revision, or endovascular management can be considered in patients with early hepatic artery thrombosis or stenosis. Hepatic artery pseudoaneurysm, arterioportal fistula, and splenic artery steal syndrome are often treated by endovascular means. Endovascular management is also preferred in patients with symptomatic portal vein stenosis, early portal vein thrombosis, and symptomatic late portal vein thrombosis, whereas surgical revision or retransplantation is preferred in patients with perioperative portal vein thrombosis occurring within 3 days of transplantation. Venoplasty with or without stent placement can be considered in patients with hepatic venous outflow tract or inferior vena cava obstruction. Transjugular intrahepatic portosystemic shunt (TIPS) may be required in transplant recipients who develop cirrhosis, often, secondary to disease recurrence, or chronic rejection. Indications for TIPS remain same in the transplant patients; however, major difference is altered vascular anatomy, for which adjunct techniques may be required to create TIPS.
ABSTRACT
OBJECTIVES: To evaluate the feasibility, safety, and efficacy of add-on transjugular-intrahepatic-portosystemic shunt (TIPS) for portal vein recanalization (PVR) in cirrhotic patients with non-tumoral chronic portal vein thrombosis (PVT) after 6 months of monitored anticoagulation therapy (ACT). METHODS: We conducted a retrospective search of the hospital database for patients who underwent TIPS for persistent PVT despite 6 months of ACT (January 2011 to August 2021). These patients were compared to control group (ACT group; no TIPS but continued on ACT). Post-TIPS periodic assessment was done to look for clinical outcome, PVR (using contrast-enhanced CT scan), and complications. RESULTS: A total of 90 patients were analyzed. Thirty-six patients in TIPS group and 54 patients in ACT group. TIPS was successfully performed in all patients. TIPS group showed complete recanalization of portal vein in 77.8%, partial recanalization in 16.7%, and stable thrombus in 5.5% of the patients. TIPS thrombosis was seen in 3 patients, all underwent successful endovascular thrombolysis. Seven patients developed post-TIPS hepatic encephalopathy and were managed conservatively. In contrast, no patient in ACT group achieved PVR on 12-month follow-up. After propensity score matching, patients in TIPS group showed significantly lower incidence of variceal re-bleeding (22.2% vs. 77.8%, p = 0.03) and refractory ascites (11.1% vs. 51.9%, p < 0.01) with significantly better 12-month survival as compared to ACT group (88.9% vs. 69.4%, p = 0.04). CONCLUSION: TIPS in cirrhotic patients with PVT result in superior recanalization rates, better control of ascites, and variceal re-bleeding resulting in better survival. TIPS may be considered a preferred therapy after anticoagulation failure. CLINICAL IMPACT: TIPS is associated with good technical and clinical success in patients of cirrhosis with PVT and should be considered in patients not responding to ACT.

OBJECTIVE: To assess the efficacy and outcomes of percutaneous ablative therapies for hepatocellular carcinoma (HCC) in the caudate lobe. METHODS: Patients within Milan criteria, who underwent thermal ablation (RFA/MWA) for HCC were analyzed. Based on the inclusion-criteria, patients were categorized in two groups. Group-1 (caudate-lobe HCC) and Group-2 (non-caudate-lobe HCC). Both the groups were analyzed for technical success (TS), local tumor progression (LTP), disease-free survival (DFS), and overall survival (OS) were compared between both the groups. Predictive factors for LTP, DFS, or OS in the study cohort were analyzed using appropriate statistical analyses. RESULTS: Twenty-one patients qualified to be in Group-1 while 130 patients fulfilled the criteria for Group-2. TS of 90.5 and 97.7% was seen after the first session of ablation for Group-1 and group-2 respectively, while a TS of 95.2% (Group-1) and 100% (Group-2) was achieved after second session. The right-intercostal-approach was used in 66.7% (n = 14) and the anterior-epigastric-approach was used in 33.3% (n = 7) of patients having caudate-lobe HCC. Procedure-related complications in both the groups were comparable. Although, statistically insignificant, LTP in the Group-1 (19.5%, n = 4) was twice that of non-caudate lobe HCC (8.5%, n = 11). The cumulative DFS rate was better in Group-2 while OS in both groups were comparable. Multivariate analysis showed: tumor size and ablative margin of 5 mm being independent predictors of LTP after percutaneous-ablation of caudate-lobe HCC. CONCLUSION: Ablative therapies for HCC in caudate lobe is feasible and safe with comparable LTP and OS to non-caudate lobe HCC. Tumor size >2 cm and lack of 5 mm ablative margin are independent predictors of LTP. ADVANCES IN KNOWLEDGE: 1. Percutaneous ablation of caudate lobe HCC is feasible using anterior epigastric approach or right intercostal approach. 2. These approaches may allow a safe and effective ablation of caudate lobe HCC with results comparable to non-caudate HCC ablation.

OBJECTIVES: To evaluate the response and outcome with prolonged intravenous antibiotics including home-based intravenous antibiotics in children with intractable cholangitis (IC) after Kasai portoenterostomy (KPE) for biliary atresia (BA). METHODS: A retrospective review of treatment and outcome of children with IC post KPE (no resolution after four weeks of antibiotics) was done between 2014 and 2020. A protocol-based antibiotic regimen was used based on sensitivity and hospital antibiogram. Children afebrile for more than three days were discharged on home intravenous antibiotics (HIVA). RESULTS: Twenty children with IC were managed with prolonged antibiotic regimen, including HIVA. All patients were initially listed for liver transplantation (LT) with indication being IC (n = 20) with portal hypertension (n = 12). Seven patients had bile lakes of which four underwent percutaneous transhepatic biliary drainage. Bile culture grew Klebsiella in four and Escherichia coli and Pseudomonas one each. There were eight children with IC who had positive blood culture with most of these organisms being gram-negative (Escherichia coli: 5, Klebsiella pneumoniae: 2, Enterococcus: 1). Median duration of antibiotics was 58 days (interquartile range [IQR] 56-84). Median follow-up period post cholangitis was three years (IQR 2-4). Following treatment, 14 patients were successfully delisted from LT waitlist and are presently jaundice-free. Two of the five patients undergoing LT died of sepsis. One patient died awaiting LT. CONCLUSION: Timely and aggressive step-up antibiotic regimen may successfully treat IC and prevent/delay LT. HIVA provides a cost-effective and comfortable environment for a child which might improve compliance with intravenous antibiotics.

PURPOSE: To study the prevalence of back pain in patients of Budd-Chiari syndrome (BCS) with inferior vena cava (IVC) obstruction, and to evaluate the role of IVC recanalization in resolution of back pain. METHODS: All patients with BCS and IVC obstruction who underwent IVC recanalization between January 2018 and October 2022 were included. Patients with degenerative spine disease or other identifiable causes for back pain were excluded; remaining patients were assessed for the presence of back pain. In patients with back pain, pain relief was assessed at 24 h following IVC recanalization. RESULTS: Fifty-eight patients with BCS and IVC occlusion were identified, of which six with degenerative spine diseases were excluded. Of the remaining 52 patients, 34 (65.4%) had back pain, with pain score between 3 and 9. Engorged epidural venous plexus on preprocedural imaging (p = 0.002), and degree of luminal narrowing (p = 0.021) had a significant association with back pain. Twenty-nine of thirty-four patients (85.3%) with back pain had pain relief immediately following IVC recanalization, more so in patients with engorged epidural venous plexus on preprocedural imaging (p < 0.001). CONCLUSION: Back pain is one of the under-reported symptoms of IVC obstruction in BCS. IVC recanalization by IVC angioplasty with or without stenting relieves back pain due to the decompression of engorged epidural veins.
ABSTRACT
BACKGROUND: Transjugular-intrahepatic portosystemic-shunt (TIPS) and SX-Ella stent Danis (DE stent) are available rescue therapies for refractory variceal bleeding in cirrhosis. Any delay in appropriate therapy is associated with high mortality. Determining the best timing for rescue TIPS is crucial and largely unknown. METHODS: Cirrhotic patients with refractory variceal bleed (n = 121) who underwent rescue TIPS within 24-h (n = 66) were included. Their early rebleed (upto 42 days) rate, 6-week and 1-year survival were compared with matched patients who underwent rescue DE stent (n = 55). Outcomes based on timing of TIPS (within 8-h/8-24 h) were also analyzed. RESULTS: At baseline, patients who received rescue DE stent were sicker with higher MELD score (27.6 ± 8.3 vs. 22.3 ± 7.9; p = 0.001), active bleeding at endoscopy (54.5% vs. 34.8%; p = 0.03) compared to TIPS-group. After propensity score matching, adjusting for MELD-Na score and non-bleed complications, DE patients (n = 34) had higher mortality at 6-week (17/34; 50%) and 1-year (29/34; 85.3%) compared to TIPS-group (20.6% and 38.2%, respectively; both p < 0.02), with higher rebleeding rate (10/34; 29.4% vs. 1/34; 2.9%, p = 0.003). Rescue TIPS placed within 8-h compared with 8-24 h had lower 6-week (48.6% vs. 12.9%; p = 0.003) and 1-year mortality (62.9% vs. 16.1%, p = 0.001) despite comparable rebleed rates (2/31; 6.5% vs. 2/35;5.7%; p = 0.90). Post-TIPS Portal pressure gradient at 6-weeks and 1-year was comparable between survivors and non-survivors. Active bleeding at endoscopy [HR = 11.8; 95% CI 2.96-47.53], presence of AKI [HR = 5.8; 95% CI 1.92-17.41], MELD-Na > 24 [HR = 1.1; 95% CI 1.0-1.17], mean arterial pressure > 64.5 mmHg [HR = 0.8; 95% CI 0.75-0.92] independently predicted 6-week mortality in rescue TIPS-group. CONCLUSIONS: Rescue TIPS placement preferably within 8-h of refractory variceal bleed improves short- and long-term survival. It provides better outcome than DE stent for control of bleeding and prevention of rebleeding, even in patients with high MELD-Na score.

BACKGROUND: Hepatic artery-related complications (HARC) after live donor liver transplantation (LDLT) is associated with high morbidity and mortality rate. METHODS: Prospectively maintained data from July 2011 to September 2020 was analyzed for etiology, detection, management, and outcome of HARC. RESULTS: Six hundred fifty-seven LDLT (adult 572/pediatrics 85) were performed during the study period. Twenty-one (3.2%) patient developed HARC; 16 (2.4%) hepatic artery thrombosis (HAT) and 5 (0.76%) non-thrombotic hepatic artery complication (NTHAC). Ninety percent (19/21) HARC were asymptomatic and detected on protocol Doppler. Median time to detection was day 4 (range - 1 to 35), which included 18 early (within 7 days) vs 3 late incidents. Only one pediatric patient had HAT. Seven patients underwent surgical revascularization, 11 had endovascular intervention and 3 with attenuated flow required only systemic anticoagulation. All NTHAC survived without any sequelae. Revascularization was successful in 81% (13/16) with HAT. Biliary complications were seen in 5 (23.8%); four were managed successfully. Overall mortality was 14.8% (3/21). The 1-year and 5-year survival were similar to those who did not develop HARC (80.9% vs 84.2%, p = 0.27 and 71.4% vs 75.19%, p = 0.36 respectively) but biliary complications were significantly higher (23.8% vs 14.2%, p = 0.03). On multivariate analysis, clockwise technique of arterial reconstruction was associated with decreased risk of HAT (1.7% vs 4.1% (p value - 0.003)). CONCLUSION: Technical refinement, early detection, and revascularization can achieve good outcome in patients with HARC after LDLT.
