Elastography-The New Standard in the Assessment of Fibrosis After Pediatric Liver Transplantation?

Background: The development of graft fibrosis after pediatric liver transplantation (PLT) remains a major concern as it can lead to graft failure and ultimately graft loss. Elastography is a non-invasive method to assess liver fibrosis, but its role in the posttransplant setting is unclear. The aim of our study was to evaluate shear wave elastography (SWE) in the assessment of liver fibrosis after PLT, including split-liver recipients.

Biological abdominal wall expansion in pediatric liver recipients after transplantation with large-for-size organs.

Background: After pediatric split liver transplantation, intra-abdominal loss of domain due to large-for-size left lateral grafts is a frequent problem for fascial closure and potentially leads to reduced liver perfusion and abdominal compartment syndrome. Therefore, delayed fascial closure with the use of temporary silastic meshes and reoperation or alternative fascial bridging procedures are necessary.

Methods: Between March 2019 and October 2021, biologic meshes were used for abdominal wall expansion in 6 cases of pediatric split liver transplantation.

Predictors of portal vein complications after pediatric liver transplantation: A German center experience.

Background: Portal vein complications (PVCs) after pediatric liver transplantation (LT) are sometimes asymptomatic, especially in the early phase, and can threaten both the graft and patient's survival. Therefore, the purpose of this study is to analyze the risk factors for portal vein thrombosis (PVT) and portal vein stenosis (PVS) after pediatric LT.

Methods: All pediatric patients (n = 115) who underwent primary LT at Regensburg University Hospital between January 2010 and April 2017 were included in this study.

Super selective percutaneous transhepatic coil embolization of intrahepatic pseudoaneurysm after pediatric liver transplantation: a case report.

Background: Intrahepatic arterial pseudoaneurysms are a rare, life-threatening complication after pediatric liver transplantation. Treatment of choice represents interventional radiological management with endovascular embolization of the segmental artery proximal and distal to the aneurysm. However, this technique results in loss of arterial perfusion distal to the aneurysm with subsegment arterial ischemia.

Sequential CT arterioportography-arteriosplenography depicts individual haemodynamic changes in children with portal hypertension without cirrhosis.

We evaluated sequential computed tomography (CT) arterioportography-arteriosplenography for the assessment of venous pathways in children with portal hypertension without cirrhosis. Institutional Review Board approval was obtained for this retrospective, single-centre study. CT was performed after contrast application via catheters placed in the superior mesenteric artery (CT arterioportography) and the splenic artery (CT arteriosplenography) consecutively.

Risk factors associated with cognitive impairment in patients after pediatric liver transplantation.

Data on cognitive function after pLT are rare, particularly regarding children with cognitive impairment. From 2016 to 2018, we evaluated cognitive function in 36 patients after pLT aged 6-17 years with the WISC IV (at least 1 year after transplantation) and analyzed potential risk factors for cognitive impairment (IQ < 70) by means of retrospective medical data (peri-, intra-, and post-operative factors, and donor and specific organ data of the primary liver transplant) on an exploratory base. At a median age of 9.

Acute Kidney Injury and Renal Regional Oxygen Saturation During Pediatric Liver Transplantation.

BACKGROUND Kidney injury is a complication among children undergoing liver transplantation (pLTx). Cystatin C serum concentration seems to be superior to creatinine-based determination of kidney injury in adults and children. Near-infrared spectroscopy (NIRS) technology provides non-invasive and real-time measurement of renal tissue oxygenation.

Tacrolimus Aggravated Tube Feeding Syndrome with Acute Renal Failure in a Pediatric Liver Transplant Recipient.

Acute renal failure can be caused by calcineurin inhibitors (CNIs), due to arteriolopathy and altered tubular function. Within this context, we present the case of a 14-month-old liver transplant recipient who suffered an acute polyuric renal failure during a short episode of hypercaloric feeding. In our case, CNI-induced distal RTA led to nephrocalcinosis and therefore to secondary nephrogenic diabetes insipidus.

Glucose Metabolism and Associated Outcome After Pediatric Liver Transplantation.

Background: Despite hypoglycemia and hyperglycemia being frequently observed in the early postoperative phase, information on glucose metabolism after pediatric liver transplantation (pLT) is scarce.

Methods: The goal of this retrospective single-center study, which included 46 patients who consecutively underwent 55 liver transplantations, was to gather data on glucose uptake, the prognostic relevance of hyperglycemia, and the safety of insulin administration in patients after pLT.

Results: In this study population, glucose intake to keep blood sugar levels (BSLs) within the targeted range of 120 to 200 mg/dL (6.

Current developments in pediatric liver transplantation.

In 1953, the pioneer of human orthotopic liver transplantation (LT), Thomas E Starzl, was the first to attempt an orthotopic liver transplant into a 3 years old patient suffering from biliary atresia. Thus, the first LT in humans was attempted in a disease, which, up until today, remains the main indication for pediatric LT (pLT). During the last sixty years, refinements in diagnostics and surgical technique, the introduction of new immunosuppressive medications and improvements in perioperative pediatric care have established LT as routine procedure for childhood acute and chronic liver failure as well as inherited liver diseases.

Kinetics of interleukin-6, procalcitonin, and C-reactive protein after pediatric liver transplantation.

In the early phase after pediatric liver transplantation (pLT) several concomitant factors may reduce the performance of established sepsis markers. To date, their clinical interpretation is hindered by a lack of information on their postoperative kinetics. To gather more information on the postoperative course and their changes in bacterial sepsis, we prospectively studied C-reactive protein (CRP), interleukin-6 (IL-6), and procalcitonin (PCT) on 9 perioperative days in 25 consecutive pLTs.

High levels of procalcitonin in the early phase after pediatric liver transplantation indicate poor postoperative outcome.

Background/aims: To date, no data is available about procalcitonin (PCT) levels and its relevance to morbidity and graft function in the early phase after pediatric liver transplantation (pLTx). The aim of this study was to analyse the prognostic relevance of early postoperative PCT elevations in pediatric liver recipients.

Methodology: Thirty pediatric patients who underwent 32 liver transplantations were included into this observational single-center study.

An unexpected ferromagnetic foreign body detected during emergency magnetic resonance imaging: a case report.

Background: Sedation or anesthesia is often necessary in pediatrics when magnetic resonance imaging is performed. This anesthesia outside of the operation room combines specific requirements and risks. Ferromagnetic foreign bodies are a clear contraindication for magnetic resonance imaging due to the high magnetic field within the scanner.

Percutaneous treatment of biliary complications in pediatric patients after liver transplantation.

Purpose: Evaluation of the efficiency and safety of the percutaneous treatment of biliary complications in pediatric liver transplant recipients.

Methods: We conducted a retrospective analysis of children who underwent biliary percutaneous interventions after pediatric liver transplantation (PLT) over a 4-year period. Kind of biliary complication, interval between liver transplantation and intervention, status of the vessels, procedural interventional management, technical and clinical success, course of cholestasis, PTBD-related complications and patient survival were analyzed.

Liver transplantation for malignancy: current treatment strategies and future perspectives.

In 1967, Starzl et al performed the first successful liver transplantation for a patient diagnosed with hepatoblastoma. In the following, liver transplantation was considered ideal for complete tumor resection and potential cure from primary hepatic malignancies. Several reports of liver transplantation for primary and metastatic liver cancer however showed disappointing results and the strategy was soon dismissed.

Interventional radiological treatment of perihepatic vascular stenosis or occlusion in pediatric patients after liver transplantation.

Purpose: Evaluation of the efficacy and safety of percutaneous treatment of vascular stenoses and occlusions in pediatric liver transplant recipients.

Methods: Fifteen children (mean age 8.3 years) underwent interventional procedures for 18 vascular complications after liver transplantation.

[Percutaneous thrombus aspiration and thrombolysis for the treatment of acute portal vein thrombosis in a 5-year-old child].

Early portal vein thrombosis is a frequent and severe complication following pediatric liver transplantation. The clinical presentation is characterized by signs and symptoms of portal hypertension such as ascites and digestive hemorrhage. Primary treatment consists of heparin therapy.

Dermatitis herpetiformis presenting as digital petechiae.

We present a 15-year-old female patient with a 6-month history of recurrent painful petechiae on the fingers and feet. Trauma or pressure were denied, but she reported recurrent tonsillitis and urinary tract infections and a single event of bilateral scotoma. Extensive investigations (e.
