Risk factors for primary graft dysfunction after lung transplantation.
The International Society for Heart and Lung Transplantation has proposed a new grading system for primary graft dysfunction based on the ratio of arterial oxygen to fraction of inspired oxygen measured within 48 hours after lung transplantation. Worsening primary graft dysfunction grade is associated with increased operative mortality rates and decreased long-term survival. This study evaluated donor and recipient risk factors for postoperative International Society for Heart and Lung Transplantation grade 3 primary graft dysfunction. ⋯ Our analysis of donor and recipient risk factors for severe primary graft dysfunction identified patient groups at high risk for poor outcomes after lung transplantation that might benefit from treatments aimed at reducing reperfusion injury.

Modified reperfusion in clinical lung transplantation: the results of 100 consecutive cases.
Severe primary graft dysfunction occurs in 10% to 20% of lung transplant recipients and is the leading cause of early death after lung transplantation. We hypothesized that altering the content of the initial reperfusate and maintaining a low reperfusion pressure after surgical implantation would lead to a low incidence of primary graft dysfunction. ⋯ The technique of modified reperfusion in human lung transplantation is associated with a low incidence of severe primary graft dysfunction and favorable short-term outcomes.

Technical challenges in totally endoscopic robotic coronary artery bypass grafting.
Robotic technology is a prerequisite for performance of totally endoscopic coronary artery bypass grafting. During the implementation phase of totally endoscopic coronary artery bypass, surgeon-related technical difficulties might be encountered. It was the aim of this study to assess the incidence of these challenges, to find risk factors, and to describe clinical results associated with technical errors. ⋯ We conclude that technical difficulties during totally endoscopic coronary artery bypass grafting translate into markedly increased operative time, moderately prolonged postoperative ventilation time, and slightly increased hospital stay. Short-term survival and freedom from angina, however, do not seem to be compromised.
