Postoperative hemorrhagic stroke (HS) is a rare yet devastating complication after liver transplantation (LT). Unruptured intracranial aneurysm (UIA) may contribute to HS; however, related data are limited. We investigated UIA prevalence and aneurysmal subarachnoid hemorrhage (SAH) and HS incidence post-LT.
View Article and Find Full Text PDFBackground And Aims: Despite frequent cirrhotic cardiomyopathy or subclinical heart failure (HF), the prognostic value of peri-liver transplant (LT) B-type natriuretic peptide (BNP) has been poorly studied in advanced liver disease. We examined the association between BNP and mortality in a large cohort of LT patients and identified risk factors for peri-LT BNP increase.
Approach And Results: Using prospectively collected data from the Asan LT Registry between 2008 and 2019, 3,811 patients who measured serial pretransplant BNP (preBNP) and peak BNP levels within the first 3 posttransplant days (postBNP ) were analyzed.
Introduction: Early allograft dysfunction (EAD) is known to be a prototype of graft failure and ultimately influences long-term graft failure or death. We hypothesized that pretransplant thrombogenicity evaluated by procoagulant and anticoagulant, von Willebrand factor (vWF), factor Ⅷ (FⅧ), protein C (PC) and their imbalance ratio of vWF-to-PC (vWFPCR) and FVIII-to-PC (FⅧPCR), is associated with EAD and 90-day graft failure after living-related liver transplantation (LDLT) and contributes to further exacerbation of graft dysfunction when coexists with systemic inflammation.
Material And Methods: Of 1199 prospectively registered LDLT patients, 698 with measurements of each thrombogenicity parameters were analyzed.
Background: More than 400 liver transplants were performed at Asan Medical Center (AMC) in 2011, and over 500 liver transplants including 420 living-donor liver transplants (LDLTs) were performed in 2019. Herein, we report the methodology of these procedures.
Methods: Since the first adult LDLTs at AMC using the left and right lobes were successfully performed, various innovative techniques and approaches have been developed: modified right lobe, dual graft, donor exchange for ABO incompatibility, expansion of indications and no-touch techniques for hepatocellular carcinoma, intraoperative cine-portogram and additional intervention for large collaterals, management of portal vein thrombosis (PVT) and stenosis, salvage LDLT after major hepatectomy, and timely LDLT for patients with acute-on-chronic liver failure.
Background: Given the severe shortage of donor liver grafts, coupled with growing proportion of cardiovascular death after liver transplantation (LT), precise cardiovascular risk assessment is pivotal for selecting recipients who gain the greatest survival benefit from LT surgery. We aimed to determine the prognostic value of pre-LT combined measurement of B-type natriuretic peptide (BNP) and high-sensitivity troponin I (hsTnI) in predicting early post-LT mortality.
Methods: We retrospectively evaluated 2,490 consecutive adult LT patients between 2010 and 2018.
Background And Aim: The proportional increase of corrected QT interval (QTc) along end-stage liver disease (ESLD) severity may lead to inconsistent outcome reporting if based on conventional threshold of prolonged QTc. We investigated the comprehensive QTc distribution among ESLD patients and assessed the association between QTc > 500 ms, a criterion for diagnosing severe long-QT syndrome, and the 30-day major adverse cardiovascular event (MACE) after liver transplantation (LT) and identified the risk factors for developing QTc > 500 ms.
Methods: Data were collected prospectively from the Asan LT Registry between 2011 and 2018, and outcomes were retrospectively reviewed.
