Lung Preservation With Perfadex or Celsior in Clinical Transplantation: A Retrospective Single-Center Analysis of Outcomes.

2015

BACKGROUND Despite improvement of lung preservation by the introduction of low-potassium dextran (LPD) solution, ischemia-reperfusion injury remains a major contributor to early post-lung transplant graft dysfunction and mortality. After favorable experimental data, Celsior solution was used in our clinical lung transplant program. Data were compared with our historic LPD cohort. METHODS Between January 2002 and January 2005, 209 consecutive lung transplantations were performed with LPD. These were compared to 208 transplants between February 2005 and September 2007 with Celsior. Endpoints included posttransplant PaO2/FiO2 ratio at different timepoints after intensive care unit (ICU) admiss…

Initial topical cooling followed by backtable Celsior flush perfusion provides excellent early graft function in porcine single lung transplantation …

2013

Topical in situ cooling of the donor lungs is a prerequisite for procurement of non-heart-beating donor lungs and may be of interest for living related lung donation.Twenty-four single lung transplants were performed in 4 groups of Landrace pigs (6 per group). Control LPD, control Celsior and topical cooling in situ, followed by LPD (exLPD) or Celsior (exCel) ex situ flush, were employed. All lungs were perfused antegrade with 1 liter of solution at 4°C. Lungs were stored immersed in preservation solution for 24 hours at 4°C. After transplantation of the left lung, the right recipient bronchus and pulmonary artery were clamped.Four of 6 animals each in the LPD and Celsior groups and all 6 a…

Comprehensive three‐dimensional morphology of neoangiogenesis in pulmonary veno‐occlusive disease and pulmonary capillary hemangiomatosis

2019

Abstract Pulmonary veno‐occlusive disease (PVOD) is a rare lung disease characterized by fibrotic narrowing of pulmonary veins leading to pulmonary hypertension (PH) and finally to death by right heart failure. PVOD is often accompanied by pulmonary capillary hemangiomatosis (PCH), a marked abnormal proliferation of pulmonary capillaries. Both morphological patterns often occur together and are thought to be distinct manifestations of the same disease process and accordingly are classified together in group 1′ of the Nice classification of PH. The underlying mechanisms of these aberrant remodeling processes remain poorly understood. In this study, we investigated the three‐dimensional struc…

Evolving Risk Factors for Mortality after Lung Transplantation over the Last 10 Years: Insights from a Single-Centre Database

2016

s S233 218 (82%) patients received pooled platelet transfusion -median (IQR) 1(1-2) U. 209 (79%) and 129 (49%) patients received fresh frozen plasma (FFP) and cryoprecipitate with a median (IQR) of 3(2-4) and 0(0-0) U respectively. Conclusion: Rate and volume of transfusion of blood products compare favourably with centres performing surgery off CPB or on ECMO. Requirement for ECMO particularly for BTT, but also PGD is associated with high transfusion requirements.

Retrograde in situ versus antegrade pulmonary preservation in clinical lung transplantation: a single-centre experience.

2014

OBJECTIVE Experimental and clinical studies have indicated a beneficial effect of retrograde lung preservation on post-transplant results. Accordingly, we conducted a non-randomized trial. METHODS A total of 209 consecutive recipients transplanted with low-potassium dextrane (LPD)-preserved lungs were eligible for analysis. Antegrade lung preservation (AP) was performed in 173 patients and retrograde in situ perfusion (RP) in 36 patients using low-potassium dextrane solution in all cases. The prostacycline was added to preservation solution. RESULTS The main donor, graft and recipient characteristics did not differ significantly between groups. There was a beneficial trend toward improved o…
