Ideal perfusion during ascending aorta-arch surgery should allow easy implementation of antegrade cerebral perfusion while avoiding atheroembolization or false lumen perfusion in dissections. We report favorable experience with direct axillary artery cannulation. ⋯ Our results suggest that axillary artery cannulation, successful in 95% of patients, may be the optimal technique for reducing perfusion-related morbidity and adverse outcome in operations for acute dissection, atherosclerotic, and degenerative aneurysmal disease. It deserves serious consideration in all patients older than 65 requiring cardiopulmonary bypass.

Comparative Study
Trainees operating on high-risk patients without cardiopulmonary bypass: a high-risk strategy?
The safety of teaching off-pump coronary artery bypass grafting to trainees is best tested in high-risk patients, who are more likely to experience significant morbidity after surgery. This study compared outcomes of off-pump coronary artery bypass grafting operations performed by consultants and trainees in high-risk patients. ⋯ Off-pump coronary artery bypass grafting surgery in high-risk patients can be safely performed by trainees.

The outcome in patients treated by conventional coronary artery bypass grafting (CABG) for coronary artery disease is negatively influenced by the presence of diabetes. The relative effect of diabetes in patients undergoing isolated minimally invasive revascularization of the left anterior descending artery (LAD) using the internal thoracic artery (ITA) has as yet not specifically been looked at. Thus, this study sought to evaluate the impact of diabetes on mid-term outcome following minimally invasive coronary artery bypass grafting (MIDCAB). ⋯ The results support diabetes to be an independent risk factor for outcome in patients with MVD undergoing a MIDCAB procedure in analogy to those undergoing CABG procedures. Diabetics with isolated disease of the LAD, however, benefit out of proportion from this treatment modality.

Case Reports
Successful therapy of severe pneumonia-associated ARDS after pneumonectomy with ECMO and steroids.
Pneumonia and acute respiratory distress syndrome are life-threatening complications after pneumonectomy carrying high mortality. Because pulmonary reserve is inadequately low, an effective therapeutic strategy is needed to treat hypoxia. ⋯ We report a case of successful extracorporeal membrane oxygenation therapy in a patient with pneumonia-associated acute respiratory distress syndrome after pneumonectomy. Methylprednisolone therapy caused a dramatic improvement of pulmonary and systemic organ function.

We report the experience of a single institution with the minimally invasive resection of mediastinal masses using the da Vinci robotic surgical system. ⋯ These preliminary results of our series suggest that application of the da Vinci robotic surgical system for resection of selected mediastinal masses is technically feasible and safe. It provides an alternative to open approaches and "conventional" thoracoscopy. Nevertheless, this new technique requires further investigation in larger series and longer follow-up.
