Abstract
BACKGROUND Hepatic artery thrombosis is the most common vascular complication of liver transplantation. When occurring late in the postoperative course, it may have no clinical repercussions, and conservative treatment may be implemented. Some patients, however, will develop severe biliary complications due to ischemic cholangiopathy and require retransplantation. The aim of this study is to report the outcomes of retransplantation in this population. METHODS This is a single-center retrospective study involving all adult patients who underwent liver retransplantation due to late hepatic artery thrombosis from January/2010 to December/2022. RESULTS During the study period, 1378 liver transplants were performed in our center; 147 were retransplantations, with 13 cases of late hepatic artery thrombosis (0.94%). All had symptomatic ischemic cholangiopathy. Twelve of them had already presented previous cholangitis, bilomas, or liver abscesses and had undergone biliary stenting or percutaneous drainage. The median time between the first liver transplant and late hepatic artery thrombosis diagnosis and between this diagnosis and retransplantation were 73 and 50 days, respectively. Arterial reconstruction using splenic artery, celiac trunk, or arterial conduit from the aorta was performed in 7 cases, whereas biliary reconstruction was mostly done with choledochojejunostomy (n = 8). There were 4 perioperative deaths, 2 due to primary non-function and 2 due to refractory shock after exceedingly complex retransplants. CONCLUSION Liver retransplantation due to late hepatic artery thrombosis is a rare condition that should be offered to patients who develop severe biliary complications and recurrent infections. It is nonetheless a challenging procedure associated with significant perioperative mortality.

Mishra S, Taneja S. Algorithmic Approach to Deranged Liver Functions After Transplantation. J Clin Exp Hepatol 2024; 14:101317. [PMID: 38264576 PMCID: PMC10801315 DOI: 10.1016/j.jceh.2023.101317] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Accepted: 12/06/2023] [Indexed: 01/25/2024] Open
Abstract
Liver transplant (LT) recipients require close follow-up with regular monitoring of the liver function tests (LFTs). Evaluation of deranged LFT should be individualized depending upon the time since LT, peri-operative events, clinical course, and any complications. These derangements can range from mild and asymptomatic to severe and symptomatic elevations requiring expedited personalized assessment and management. Pattern of LFT derangement (hepatocellular, cholestatic, or mixed), donor-recipient risk factors, timing after LT (post-operative, 1-12 months, and >12 months since LT) along with clinical context and symptomatology are important considerations before proceeding with the initial evaluation. Compliance to immunosuppression and drug interactions should be ascertained along with local epidemiology of infections. Essential initial evaluation must include an ultrasound abdomen with Doppler to rule out any structural causes such as biliary or vascular complications apart from focussed laboratory evaluation. Early allograft dysfunction, ischemia reperfusion injury, small-for-size syndrome, biliary leaks, hepatic artery, and portal vein thrombosis are usual culprits in the early post-operative period whereas viral hepatitis (acute or reactivation), opportunistic infections, and recurrence of the primary disease are more frequent in the later period. Graft rejection, biliary strictures, sepsis, and drug induced liver injury remain possible etiologies at all times points after LT. Initial evaluation algorithm must be customized based on history, clinical examination, risk factors, and pattern and severity of deranged LFT. Allograft rejection is a diagnosis of exclusion and requires liver biopsy to confirm and assess severity. Empirical treatment of rejection sans liver biopsy is discouraged.

Abstract
Hepatic artery thrombosis (HAT) is a devastating vascular complication following liver transplantation, requiring prompt diagnosis and rapid revascularization treatment to prevent graft loss. At present, imaging modalities such as ultrasound, computed tomography, and magnetic resonance play crucial roles in diagnosing HAT. Although imaging techniques have improved sensitivity and specificity for HAT diagnosis, they have limitations that hinder the timely diagnosis of this complication. In this sense, the emergence of artificial intelligence (AI) presents a transformative opportunity to address these diagnostic limitations. The develo pment of machine learning algorithms and deep neural networks has demon strated the potential to enhance the precision diagnosis of liver transplant com plications, enabling quicker and more accurate detection of HAT. This article examines the current landscape of imaging diagnostic techniques for HAT and explores the emerging role of AI in addressing future challenges in the diagnosis of HAT after liver transplant.

Abstract
BACKGROUND AIMS Roux en y anastomosis is a preferred method of biliary reconstruction in liver transplantation that involves living donors or pediatric patients. However, biliary stricture is a frequent and serious complication, accounting for up to 40% of biliary complications in these patients. Previously, we demonstrated that extraluminal delivery of adipose-derived (AD) mesenchymal stromal cells (MSCs) decreased peri-biliary fibrosis and increased neo-angiogenesis in a porcine model of duct-to-duct biliary anastomosis. In this study, we used a porcine model of Roux en y anastomosis to evaluate the beneficial impact of a novel intraluminal MSC delivery system. METHODS Nine animals were divided into three groups: no stent (group 1), bare stent (group 2) and stent coated with AD-MSCs (group 3). All animals underwent cholecystectomy with roux en y choledochojejunostomy. Two animals per group were followed for 4 weeks and one animal per group was followed for 8 weeks. Cholangiograms and blood were sampled at baseline and the end of study. Biliary tissue was collected and examined by Masson trichrome staining and immunohistochemical staining for MSC markers (CD34 and CD44) and for neo-angiogenesis (CD31). RESULTS Two of three animals in group 1 developed an anastomotic site stricture. No strictures were observed in the animals of group 2 or group 3. CD34 and CD44 staining showed that AD-MSCs engrafted successfully at the anastomotic site by intraluminal delivery (group 3). Furthermore, biliary tissue from group 3 showed significantly less fibrosis and increased angiogenesis compared with the other groups. CONCLUSIONS Intraluminal delivery of AD-MSCs resulted in successful biliary engraftment of AD-MSCs as well as reduced peri-biliary fibrosis and increased neo-angiogenesis.

Abstract
Pyogenic liver abscess (PLA) is a life-threatening infection in both liver transplant (LT) and non-LT patients. Several risk factors, such as benign and malignant hepatopancreatobiliary diseases and colorectal tumors have been associated with PLA in the non-LT population, and hepatic artery stricture/thrombosis, biliary stricture, and hepaticojejunostomy in the LT patients. The objective of this study is to compare the outcomes of patients with PLA in LT and non-LT patients and to determine the risk factors associated with patient survival. From January 2000 to November 2020, a total of 296 adult patients were diagnosed of PLA in our institution, of whom 26 patients had previously undergone liver transplantation (LTA group), whereas 263 patients corresponded to the non-LTA population. Seven patients with PLA who had undergone previous kidney transplantation were excluded from this retrospective study. Twenty-six patients out of 1503 LT developed PLA (incidence of 1.7%). Median age was significantly higher in non-LTA patients (p = .001). No significant differences were observed in therapy. PLA recurrence was significantly higher in LTA than in non-LTA (34.6% vs. 14.8%; p = .008). In-hospital mortality was greater in the LT group than in the non-LT group (19.2% vs. 9.1% p = .10) and was identified in multivariable analysis as a risk factor for mortality (p = .027). Mortality rate during follow-up did not show significant differences between the groups: 34.6% in LTA patients versus 26.2% in non-LTA patients (p = .10). The most common causes of mortality during follow-up were malignancies, Covid-19 infection, and neurologic disease. 1-, 3-, and 5-year actuarial patient survival rates were 87.0%, 64.1%, and 50.4%, respectively, in patients of LTA group, and 84.5%, 66.5%, and 51.0%, respectively, in patients with liver abscesses in non-LTA population (p = .53). In conclusion, LT was a risk factor for in hospital mortality, but not during long-term follow-up.

The role of T-tubes and abdominal drains on short-term outcomes in liver transplantation - A systematic review of the literature and expert panel recommendations. Clin Transplant 2022; 36:e14719. [PMID: 35596705 PMCID: PMC10078006 DOI: 10.1111/ctr.14719] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Accepted: 04/20/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND This systematic review and expert panel recommendation aims to answer the question regarding the routine use of T-tubes or abdominal drains to better manage complications and thereby improve outcomes after liver transplantation. METHODS Systematic review following PRISMA guidelines and recommendations using the GRADE approach derived from an international expert panel to assess the potential risks and benefits of T-tubes and intra-abdominal drainage in liver transplantation (CRD42021243036). RESULTS Of the 2996 screened records, 33 studies were included in the systematic review, of which 29 (six RCTs) assessed the use of T-tubes and four regarding surgical drains. Although some studies reported less strictures when using a T-tube, there was a trend toward more biliary complications with T-tubes, mainly related to biliary leakage. Due to the small number of studies, there was a paucity of evidence on the effect of abdominal drains with no clear benefit for or against the use of drainage. However, one study investigating the open vs. closed circuit drains found a significantly higher incidence of intra-abdominal infections when open-circuit drains were used. CONCLUSIONS Due to the potential risk of biliary leakage and infections, the routine intraoperative insertion of T-tubes is not recommended (Level of Evidence moderate - very low; grade of recommendation strong). However, a T-tube can be considered in cases at risk for biliary stenosis. Due to the scant evidence on abdominal drainage, no change in clinical practice in individual centers is recommended. (Level of Evidence very low; weak recommendation).

Abstract
BACKGROUND In orthotopic liver transplantation (OLT) recipients, median arcuate ligament syndrome (MALS) is considered a risk factor for hepatic arterial thrombosis (HAT), which is dreadful for OLT recipients. Different alternative surgical procedures have been proposed to overcome the impact of MALS on transplantation, but clinical evidence is still scarce.
AIM To evaluate the feasible surgical management of MALS to reduce complications in OLT patients.
METHODS Data for 288 consecutive patients who underwent OLT at The First Hospital of Jilin University between January 2017 and July 2020 were retrospectively reviewed. The surgical management of median arcuate ligament (MAL) and modifications to the arterial anastomosis were recorded. The perioperative and long-term prognosis of MALS recipients were noted. Detailed preoperative and postoperative data of patients were analyzed in a descriptive manner.
RESULTS Eight patients with MALS were included in this study. The first patient with MALS received no intervention during the primary surgery and developed postoperative HAT. Salvage liver transplantation with MAL division was successfully performed. Gastroduodenal artery (GDA) preservation with splenic artery ligation was performed on three patients, only GDA preservation was performed on two patients, and no intervention was performed on two patients. No patient developed HAT after surgery and postoperative recovery was satisfactory.
CONCLUSION The preservation of collateral circulation between the superior mesenteric artery and celiac trunk via the GDA with or without splenic artery ligation is a safe and feasible alternative to MAL division.

Abstract
BACKGROUND The aims of this study were to investigate if recipient artery choice in right lobe living donor liver transplant affects postoperative complications and discuss solutions accordingly. METHODS Three hundred fourteen right lobe living donor liver transplantation patients were divided into 2 groups: 163 patients using right hepatic artery as the recipient vessel and 151 patients using left hepatic artery as the recipient vessel. Cases involving 2 recipient blood vessels or the use of other blood vessels as recipient vessels were excluded. RESULTS Overall vascular embolism rate in both groups was 1.3%, and our complication rate was lower than those in previous studies. There was no significant difference in complication rate between the groups, but a significant difference in recipient/donor artery size ratio was noted. CONCLUSIONS Although left hepatic artery's anatomical position makes it less affected by bile duct anastomosis and thus fewer postoperative complications, we believe that the ratio of the donor-recipient blood vessel size and the length of the anastomosis vessel stumps are the key factors that affect the outcome of the vascular anastomosis.

Abstract
Background. The use of pediatric grafts for liver transplantation (LT) into adult recipients is rare, and reported outcomes are conflicting. The aim of this study is to evaluate the outcomes in adult recipients following LT with grafts from deceased pediatric donors. Methods. A retrospective study identifying adult LT between 2010 and 2020 using pediatric deceased donor liver grafts was conducted. Adults undergoing LT with deceased donor pediatric grafts (age ≤ 12) were identified and matched 1:2 with adults receiving adult grafts (age ≥ 18) based on recipient age (±10 y), model for end-stage liver disease (MELD) score at transplant (±5 points) and etiology of liver disease. To assess real liver size differences between the pediatric-donor and adult-donor groups, patients receiving a graft from a donor between 13 and 17 y were excluded from the main analysis and studied independently. Outcomes between the groups were compared. Complication rates were identified and graded using Clavien–Dindo classification. Graft and patient survival were assessed by Kaplan–Meier curves. Results. Twelve adult LT recipients with whole liver grafts from deceased pediatric donors were matched with 24 adult recipients of adult donors. Recipient age and MELD score were similar between groups. Recipients of pediatric grafts were more likely to be female (66.7% versus 16.7%, P = 0.007) and leaner (body mass index = 24.4 versus 29.9, P = 0.013). Alcohol-related cirrhosis was the most prevalent liver disease etiology in both groups (P = 0.96). There was no significant difference in length of stay, readmissions, early complications, or major complications between groups. Vascular and biliary complication rates were similar. Actuarial graft and patient survival at 1, 3, and 5 y were 100/100/100 versus 96/96/96 (P = 0.48). Conclusions. Excellent patient and graft survival is achievable with LT using young pediatric deceased donor grafts in smaller adult recipients. Outcomes are comparable with recipients of age and MELD-matched adult donors. Careful donor MELD-score recipient matching and close monitoring for potential biliary and vascular complications are crucial to achieve acceptable outcomes.

Abstract
BACKGROUND Impairment of hepatic arterial flow including hepatic arterial thrombosis (HAT), hepatic arterial stenosis (HAS), and splenic artery steal syndrome (SASS) is potentially life-threatening complications. The proposed early diagnosis and urgent treatment strategy of graft arterial flow reduction aim to decrease morbidity and mortality. METHODS Pediatric patients with known hepatic arterial flow impairment were retrospectively reviewed. Patients were grouped by occlusive (HAT) and non-occlusive (HAS/SASS) arterial flow reduction. Patients with HAT were further divided in two groups based on the estimated maximal hepatic artery occlusion time ≤8 and >8 hours. RESULTS Impairment of hepatic arterial flow developed in 32 of 416 pediatric liver transplant recipients. HAT, HAS, and SASS incidences were 4.1% (n = 17), 2.2% (n = 9), and 1.4% (n = 6), respectively. Neither graft loss nor death occurred in the non-occlusive group. The probabilities of sepsis (OR, 1.7; 95% CI, 1.14-2.53; P=.008) and graft loss or death (OR, 1.42; 95% CI, 1.04-1.92; P=.046) were higher in the occlusive group. Patients with estimated maximal duration of hepatic artery occlusion ≤ 8 hours (n = 7; 41.2%) did not have ischemic-type biliary lesions and sepsis (P=.044 and 0.010, respectively) but had excellent 3-year graft survival compared with > 8 hours group (100% vs 40%; P=.037). Multivariate analysis revealed HAT manifestation by fever was associated with increased chances of graft loss or death. CONCLUSION Occlusive arterial complications impose higher risks of graft loss and death. Thorough arterial supply monitoring by Doppler ultrasonography and urgent endovascular arterial flow restoration may salvage both graft and the recipient.

Abstract
BACKGROUND Hepatic artery thrombosis (HAT), a serious complication after orthotopic liver transplantation, almost always leads to morbidity and mortality without urgent revascularization or retransplantation, especially if HAT occurs within a few days after transplantation. CASE PRESENTATION Herein we describe a case report of an orthotopic liver transplantation patient surviving without hepatic artery flow due to HAT on postoperative day 1. Reanastomosis, thrombectomy, and intra-arterial thrombolysis were performed, but only retrograde arterial flow by Doppler ultrasound, not by angiography, could be demonstrated in the hepatic artery. This case report is in compliance with the Declaration of Helsinki and the Declaration of Istanbul. CONCLUSION Based on the evidence from this patient, we believe that patients with failed revascularization can experience a long-term survival with conservative treatment. Retransplantation should be evaluated based on laboratory findings because graft function in individual patients can recover.

Abstract
BACKGROUND Ischemic cholangiopathy (IC) has a known poor prognosis. However, the risks and outcomes of this complication after transcatheter arterial chemoembolization (TACE) in hepatectomized patients are poorly documented. This study aimed to evaluate the incidence of and to identify the predictive factors for IC following TACE for recurrent hepatocellular carcinoma (HCC) after hepatectomy. METHOD From a cohort with a total of 486 patients who underwent resection for HCC, we included all consecutive patients who were treated with TACE for recurrent HCC after hepatectomy between 2000 and 2017. IC was defined by the coexistence of biological cholestasis and morphological lesions. RESULTS A total of 156 patients underwent TACE for the treatment of HCC recurrence after hepatectomy. Of them, eight (5.1%) developed IC. Their prognosis was poor compared with patients without IC (3-year survival 23.4% vs 76.2%; P = 0.008). Two factors, namely, time between hepatectomy and TACE (4.8 months vs. 16.0 months, P = 0.001) and TACE for a remnant liver mobilized during hepatectomy (P = 0.001), were associated with IC. Receiver operating characteristic (ROC) curve analysis showed that 7 months was the more discriminant cutoff for the time period. IC occurred in 33.3% of the patients with the two factors, in 5.0% of those with one factor, and 0% in the absence of any factors. CONCLUSION TACE for treating HCC recurrence carries a high risk of IC when performed early after hepatectomy in a previously mobilized liver. Our results might aid in identifying candidates for TACE for recurrent HCC, considering the major effect on patient outcomes.

Abstract
BACKGROUND Thrombosis after liver transplantation is a leading cause of graft loss, morbidity, and mortality. Several known recipient- and surgery-related characteristics have been associated with increased risk of thrombosis after transplantation. Potential donor-related risk factors, however, remain largely undefined. OBJECTIVES We aimed to identify risk factors for early post-transplantation thrombosis (<90 days) and to determine the impact of early postoperative thrombosis on long-term graft and patient survival. PATIENTS/METHODS A post hoc analysis was performed of an observational cohort study including all primary, adult liver transplantations performed between 1993 and 2018. Donor-, recipient-, and surgery-related characteristics were collected. Competing risk model analyses and multivariable regression analyses were performed to identify risk factors for developing early post-transplant thrombosis and graft failure. RESULTS From a total of 748 adult liver transplantations, 58 recipients (7.8%) developed a thrombosis after a median of 7 days. Post-transplantation thrombotic events included 25 hepatic artery thromboses, 13 portal vein thromboses, and 22 other thrombotic complications. Donor history of smoking was independently associated with early postoperative thrombosis (odds ratio [OR] 2.42; 95% confidence interval [CI], 1.29-4.52). Development of early post-transplant thrombosis was independently associated with patient mortality (hazard ratio [HR] 3.61; 95% CI 1.54-8.46) and graft failure (HR 5.80, 95% CI 3.26-10.33), respectively. CONCLUSION Donor history of smoking conveys a more than two-fold increased risk of thrombosis after liver transplantation, independent of other factors. Post-transplant thrombosis was independently associated with decreased patient and graft survival.

Abstract
BACKGROUND Biliary complications in liver transplantation (LT) can cause significant morbidity or even lead to a potential graft loss and patient mortality. Oftentimes biliary internal stents (ISs) are used at the time of LT to lower the risk for or prevent these biliary complications; however, their efficacy and outcomes remain controversial. METHODS A retrospective cohort study was conducted on all of the adult patients who underwent a deceased-donor LT (DDLT) with an end-to-end choledococholedocostomy. An IS was placed across the biliary anastomosis, passing through the ampulla. We compared the demographic profiles and various outcomes between the 2 groups (no-IS group vs IS group) and examined risk factors associated with anastomotic biliary complications. RESULTS The study comprised 350 patients in the no-IS group and 132 patients in the IS group. Anastomotic biliary fistula (ABF) occurred in 5 (1.4%) and 1 (0.8%) patients in the no-IS group and the IS group, respectively (P = .55). Anastomotic biliary stricture (ABS) occurred in 53 (15.1%) and 18 (13.6%) patients, respectively (P = .68). No significant difference was found in the overall biliary complications between the 2 groups (P = .33). In multivariate logistic regression analysis, acute rejection was the only risk factor for ABS (P = .02). One biliary complication-induced mortality occurred in the no-IS group in which the patient died of an ABF-induced hepatic artery pseudoaneurysm rupture. CONCLUSION The use of biliary ISs in DDLT did not reduce the overall risk for biliary complications, but more research is needed to draw definite conclusions.

Abstract
Donation after circulatory death (DCD) is an increasing source of liver grafts for transplantation, yet outcomes have been inferior compared to donation after brain death liver transplantation. These worse outcomes are mainly due to the severe graft injury resulting from mandatory warm ischemia during DCD organ recovery. New evidence, however, indicates that improved donor selection and surgical techniques can decrease the risk of graft failure and ischemic cholangiopathy (IC). Under current best practices, DCD organs are retrieved with the super-rapid technique, optimizing timing and protecting the liver graft from detrimental warm ischemia. Graft viability is influenced by both the quantity and quality of warm ischemia, which is unique to each donor and causes various degrees of pathophysiologic consequences. Evidence also shows that the choice of preservation solution and premortem heparin administration influences graft viability. Additionally, although the precise mechanism of IC remains unknown, stasis of blood during donor warm ischemia may cause the formation of microthrombi in the peribiliary vascular plexus and ischemia of the bile duct. Importantly, thrombolytic protocols show a possible preventive modality for IC. Finally, while ex vivo machine perfusion technology has gained an interest in DCD liver transplantation, further studies are necessary to evaluate the effectiveness of this evolving field to improve graft quality and transplant outcomes.

Abstract
The most common indications for early liver retransplantation (eRe-LT) are vascular complications and primary nonfunction (PNF). These patients are usually in a critical clinical condition that can affect their chances of survival. In fact, the survival of these patients is usually lower compared with the patients undergoing a first transplant. To the best of our knowledge, no specific series of pediatric patients undergoing eRe-LT has been published to date. Therefore, the aim of this study is to report the results of eRe-LT and to analyze factors potentially related to success or failure. Our work is of a retrospective cohort study of patients who underwent eRe-LT at the Juan P. Garrahan Pediatric Hospital of Buenos Aires, Argentina, between May 1995 and December 2018 (n = 60). Re-LT was considered early when performed ≤30 days after the previous LT. A total of 40 (66.7%) patients were enrolled due to vascular causes and 20 (33.3%) were enrolled because of PNF. Of all the relisted patients, 36 underwent eRe-LT, 14 died on the waiting list, and 10 recovered without eRe-LT. A total of 23 (63.9%) patients died after eRe-LT, most of them due to infection-related complications. Survival rates at 1 and 5 years were 42.4% and 33.9%, respectively. On univariate logistic regression analysis, Pediatric End-Stage Liver Disease (PELD)/Model for End-Stage Liver Disease (MELD) scores, transplant era, and advanced life support at eRe-LT were found to be related to 60-day mortality. However, on multivariate analysis, era (odds ratio [OR], 9.3; 95% confidence interval [CI], 1.19-72.35; P = 0.033) and PELD/MELD scores (OR, 1.07; 95% CI, 1-1.14; P = 0.036) were significantly associated with 60-day patient mortality. This study found that the level of acuity before retransplant, measured by the requirement of advanced life support and the PELD/MELD score at eRe-LT, was significantly associated with the chances of post-eRe-LT patient survival.

Abstract
PURPOSE OF REVIEW Despite advances in the field, perioperative morbidity is common after liver transplantation. This review examines the current literature to provide up-to-date management of common surgical complications associated with liver transplantation. RECENT FINDINGS Research focuses on problems with anastomoses of the vena cava, portal vein, hepatic artery, and bile ducts. Interventional endoscopic and radiological techniques are used more frequently to avoid reoperation. SUMMARY Advances in the management of perioperative surgical complications have focused on minimally invasive measures that successfully treat technical problems with implantation of liver allografts from both living and deceased donors.

Pediatr Transplant 2019; 23:e13396. [PMID: 31081216 DOI: 10.1111/petr.13396] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2018] [Revised: 11/07/2018] [Accepted: 01/28/2019] [Indexed: 12/21/2022]
Abstract
BACKGROUND The lack of age- and size-matched organs result in higher waiting list mortality in pediatric recipients than adults. Organs from deceased newborns and infants are a valuable source to increase donor pool in pediatric liver transplantation. However, the feasibility and safety of using neonatal donors have not been well evaluated. METHODS From 2014 to 2016, 48 deceased donor pediatric liver transplantations with donor age younger than 1 year old in our center were enrolled in this study. The recipients were divided into three groups based on the donor age (<1 month, 1 month ≤ to <3 months, and 3 months ≤ to <1 year). Recipient's characteristics, perioperative data, and postoperative complications were compared. RESULTS Two-year patient survival rates were 87.5%, 94.4%, and 95.5%, and 2-year graft survival rates were 75%, 94.4%, and 95.5%, respectively, without significant difference. The liver grafts from donors younger than 3 months were more advantageous in terms of acute rejection and virus infection, while the young grafts were related to slight higher incidence of hepatic artery thrombosis and SFSS. Those complications could be effectively prevented or treated by our perioperative care strategies. In addition, eight recipients who received neonatal livers achieved comparable outcomes with recipients with older livers. CONCLUSION Our data revealed that the application of liver grafts from donors younger than 1 year old could achieve excellent outcome. In particular, neonatal donors could be safely used in well-selected patients.

Median Arcuate Ligament Compression in Orthotopic Liver Transplantation: Results from a Single-Center Analysis and a European Survey Study. J Clin Med 2019; 8:jcm8040550.

Abstract
Median arcuate ligament compression (MALC) potentially causes arterial complications in orthotopic liver transplantation (OLT). Here we aimed to investigate the incidence of MALC and its impact on clinical outcome after OLT. In addition, we performed an international survey among 52 European liver transplant centers to explore local protocols on the management of these patients. Data of 286 consecutive OLT recipients from a prospective database were analyzed retrospectively (05/2010-07/2017). Preoperative computed-tomography images were evaluated. Celiac axis stenosis due to MALC was found in 34 patients (12%). Intrinsic stenosis was present in 16 (6%) patients. Twenty-six patients (77%) with MALC underwent standard arterial revascularization with median arcuate ligament (MAL)-division. Patients treated for MALC had comparable baseline data and no difference was found in early- and long-term outcome compared to the rest of our cohort. Our survey found heterogeneous strategies regarding diagnosis and treatment of MALC. Only 29% of the centers reported the division of MAL in these patients as routine procedure. Even though there is no consensus on diagnosis and management of MALC among European centers, a surgical division of MAL is feasible and safe and should be considered in OLT recipients with MALC.

Abstract
Portal vein thromboses (PVTs) are associated with hepatic decompensation, worse survival, and worse liver transplant outcomes. We evaluated the impact of anticoagulation (AC) and transjugular intrahepatic portosystemic shunting (TIPS) on recanalization and mortality in patients with cirrhosis and PVT. Systematic search of electronic databases was performed. Clinical trials and observational studies that evaluated primary outcomes of recanalization and survival in patients with cirrhosis having PVT treated with AC or TIPS were included. Risk of bias was assessed. Summary odds ratios (ORs) for pooled data from the included studies were generated using a random effects model. A total of 505 studies were screened for inclusion. After review, 7 studies were ultimately included. Data from 327 patients in total were evaluated. Overall, treatment with either AC or TIPS resulted in partial or complete recanalization (OR: 4.56 [95% confidence interval, CI: 2.46-8.47]) but did not significantly impact mortality (OR: 0.57 [95% CI: 0.21-1.57]). The summary OR of AC for recanalization was 6.00 (95% CI: 2.38-15.07). The summary OR of TIPS for recanalization was 3.80 (95% CI: 1.47-9.83). The summary OR of mortality in patients treated with AC for PVT was 0.28 (95% CI: 0.08-0.95). The mortality summary OR was 1.10 (95% CI 0.23-5.16) in patients who underwent TIPS. There was insufficient data to assess complications such as hepatic encephalopathy or bleeding. Both AC and TIPS have a significant effect on recanalization. Anticoagulation appears to have a protective effect on mortality that is not seen with TIPS. More studies with control groups are need.

Abstract
Graft dysfunction of the liver allograft manifests across a spectrum in both timing posttransplantation and clinical presentation. This can range from mild transient abnormalities of liver tests to acute liver failure potentially leading to graft failure. The causes of graft dysfunction can be divided into those resulting in early and late graft dysfunction. Although nonspecific, liver biochemistry abnormalities are still the mainstay investigation used in monitoring for dysfunction. This article provides a summary of the main causes and management strategies for liver graft dysfunction in the early through late posttransplant stages.
