Too Much, Too Little, or Just Right? The Importance of Allograft Portal Flow in Deceased Donor Liver Transplantation

While portal flow (PF) plays an important role in determining graft outcomes in living donor liver transplantation, its impact in deceased donor liver transplantation (DDLT) is unclear. The aim of this study was to investigate the correlations between graft PF and graft outcomes in DDLT.

Methods: We retrospectively investigated 1001 patients who underwent DDLT between January 2007 and June 2017 at our institution. The patients were divided into 3 groups according to hazard ratio for 1-year graft loss at each PF value, which was standardized with graft weight. Graft and recipient outcomes were compared between the groups.

Hepatic flow is an intraoperative predictor of early allograft dysfunction in whole-graft deceased donor liver transplantation: An observational cohort study

Early allograft dysfunction (EAD) after liver transplantation (LT) is an important cause of morbidity and mortality. To ensure adequate graft function, a critical hepatocellular mass is required in addition to an appropriate blood supply. We hypothesized that intraoperative measurement of portal venous and hepatic arterial flow may serve as a predictor in the diagnosis of EAD.

Aim: To study whether hepatic flow is an independent predictor of EAD following LT.

Methods: This is an observational cohort study in a single institution. Hepatic arterial blood flow and portal venous blood flow were measured intraoperatively by transit flow. EAD was defined using the Olthoff criteria. Univariate and multivariate analyses were used to determine the intraoperative predictors of EAD. Survival analysis and prognostic factor analysis were performed using the Kaplan-Meier and Cox regression models.

Arterial Blood Flow Predicts Graft Survival in Liver Transplant Patients

Proper liver perfusion is essential for sufficient organ function after liver transplantation. The aim of this study was to determine the effects of portal and arterial blood flow on liver function and organ survival after liver transplantation. The arterial and portal venous blood flow was measured intraoperatively by transit time flow measurement after reperfusion for 290 consecutive liver transplants. The graft survival, hepatic cell damage (alanine aminotransferase and aspartate aminotransferase), and liver function (prothrombin ratio and bilirubin) were determined.  Read more...

Lack of a Correlation Between Portal Vein Flow and Pressure: Toward a Shared Interpretation of Hemodynamic Stress Governing Inflow Modulation in Liver Transplantation

The portal vein flow (PVF), portal vein pressure (PVP), and hepatic venous pressure gradient (HVPG) were prospectively assessed to explore their relationships and to better define hyperflow and portal hypertension (PHT) during liver transplantation (LT). Eighty-one LT procedures were analyzed. Read more...

Effects of Hemi-Portocaval Shunts For Inflow Modulation on the Outcome of Small-for-Size Grafts in Living Donor Liver Transplantation

Graft hyperperfusion in small-for-size grafts (SFSG) is considered the main causal factor of small-for-size syndrome (SFSS). We compared SFSG with a graft-to-recipient body ratio ≤0.8, with and without graft inflow modulation (GIM) by means of a hemi-portocaval shunt (HPCS).  Read more...
