Early lung retrieval from traumatic brain-dead donors does not compromise outcomes following lung transplantation.
To determine whether lung retrieval from traumatic donors performed within 24 h of brain death has a negative impact on early graft function and survival after lung transplantation (LT), when compared with those retrieved after 24 h. ⋯ In our experience, early lung retrieval after brain death from traumatic donors does not adversely affect early and long-term outcomes after LT.

Acute pulmonary embolism (PE) is a common condition frequently associated with a high mortality worldwide. It can be classified into non-massive, sub-massive and massive, based on the degree of haemodynamic compromise. ⋯ Recent advances in diagnosis and recognition of key qualitative predictors of mortality, such as right ventricular stress on echocardiography, have enabled the re-exploration of surgical pulmonary embolectomy for use in patients prior to the development of significant circulatory collapse, with promising results. We aim to review the literature and discuss the indications, perioperative workup and outcomes of surgical pulmonary embolectomy in the management of acute PE.

Randomized Controlled TrialAcetylsalicylic acid treatment until surgery reduces oxidative stress and inflammation in patients undergoing coronary artery bypass grafting.
Acetylsalicylic acid (ASA) is a cornerstone in the treatment of coronary artery disease (CAD) due to its antiplatelet effect. Cessation of aspirin before coronary artery bypass grafting (CABG) is often recommended to avoid bleeding, but the practice is controversial because it is suggested to worsen the underlying CAD. The aims of the present prospective, randomized study were to assess if ASA administration until the day before CABG decreases the oxidative load through a reduction of inflammation and myocardial damage, compared with patients with preoperative discontinuation of ASA. ⋯ Continued ASA treatment until the time of CABG reduced oxidative and inflammatory responses. Also, a likely beneficial effect upon myocardial injury was noticed. Although none of the genes known to be involved in oxidative stress or inflammation took a different expression in myocardial tissue, the genetic analysis showed interesting differences in the mRNA level. Further research in this field is necessary to understand the role of the genes.

Near-infrared spectroscopy for neuromonitoring of unilateral cerebral perfusion.
There is neither consensus regarding which methods of neuromonitoring are adequate and reliable for assessing cerebral cross-perfusion during unilateral cerebral perfusion (UCP) nor are any threshold values defined. The aim of the study was to evaluate the usefulness of near-infrared spectroscopy (NIRS) for the neuromonitoring of right-sided UCP, which is increasingly used for cerebral protection as a consequence of the recent rise in supra-aortic cannulation methods. ⋯ NIRS seems to be a reliable instrument to recognize a relevant disruption of cerebral cross-perfusion during UCP. A drop of brain oxygen saturation to 40% and/or 70% of the baseline can be considered a threshold value for sufficient cerebral cross-perfusion, at least under the flow and temperature management presented.

Lobar lung transplantation is an option that provides the possibility of transplanting an urgent listed recipient of small size with a size-mismatched donor lung by surgically reducing the size of the donor lung. We report our short- and long-term results with bilateral lobar lung transplantation (BLLT) and compare it with the long-term outcomes of our cohort. ⋯ This study demonstrates that BLLT has short- and long-term outcomes comparable with those of standard bilateral lung transplantation. The limitation of lung transplantation due to size-mismatch, particularly in smaller recipients, could be overcome by utilizing lobar lung transplantation.
