Pulmonary contusion is the usual manifestation of lung parenchymal injury after blunt chest trauma. With deceleration these parenchymal lacerations can result in cavities known as primary traumatic pulmonary pseudocysts (TPPC). We present our experience in treating this rare entity. ⋯ (1) Primary traumatic pulmonary pseudocysts are benign lesions secondary to blunt chest trauma needing only conservative treatment unless complications arise, such as hemo- or pneumothorax or infection of the cavitary lesion. (2) Computed tomography is a really sensitive method for early detection of the lesion while plain roentgenograms are sufficient for the follow up.

Comparative StudyThe effect of aprotinin on ischemia-reperfusion injury in an in situ normothermic ischemic lung model.
In the context of the physiopathology of damage due to ischemic preservation and reperfusion injury following preservation, we aimed to demonstrate the positive effects of the addition of aprotinin, a serine protease inhibitor, to low potassium dextran (LPD), used as a single-flush solution in normothermic ischemic animal models, on lung protection and the prevention of reperfusion injury. ⋯ It was observed that the addition of aprotinin to LPD solution as a pulmonary flush solution in an in situ normothermic ischemic lung model prevents reperfusion injury by means of various mechanisms and also protects the morphological, functional and biochemical integrity of the lung. In our view, therefore, the addition of aprotinin to lung protection solution will provide positive results in lung transplantation protocols.

Does off-pump coronary artery bypass (OPCAB) surgery improve the outcome in high-risk patients?: a comparative study of 1398 high-risk patients.
Although there has been some evidence supporting the theoretical and practical advantages of off-pump coronary artery bypass (OPCAB) over the conventional coronary artery bypass grafting (CABG) with cardiopulmonary bypass (CPB), it has not yet been determined which group of patients would benefit most from it. It has been advocated recently that high-risk patients could benefit most from avoidance of CPB. The aim of this retrospective study is to assess the efficacy of the OPCAB technique in multi-vessel myocardial revascularization in a large series of high-risk patients. ⋯ This retrospective study shows that using the OPCAB technique for multi-vessel myocardial revascularization in high-risk patients significantly reduces the incidence of peri-operative MI and other major complications, ITU stay and mortality. Even though the OPCAB group included a significantly higher proportion of older patients with poor LV function (EF < or =30%) and renal problems, the beneficial effect of OPCAB was evident.

Prediction of atrial fibrillation after coronary artery bypass grafting by measuring atrial peptide levels and preoperative atrial dimensions.
We prospectively tested the hypothesis that atrial enlargement and increased level of atrial natriuretic peptide, N-terminal atrial natriuretic peptide and brain natriuretic peptide would predict atrial fibrillation after coronary artery bypass grafting. ⋯ Left atrial enlargement was independent predictor for postoperative atrial fibrillation. However, atrial peptides were associated with age and did not independently predict postoperative atrial fibrillation. In addition, the wide variation of the peptide levels renders the implementation of this measure in clinical practice superfluous.
