Recently, surgeons have embraced axillary artery cannulation for type A aortic dissection repair out of concern for malperfusion phenomena with traditional femoral artery cannulation. My colleagues and I sought to determine whether these concerns are justified. ⋯ Straight femoral cannulation for all phases of type A dissection repair is appropriate and yields excellent clinical results. The anticipated malperfusion events are actually rare (2 of 79 with femoral artery cannulation, or 2.5%).

The operative technique of a transcervical-subxiphoid-videothoracoscopic "maximal" thymectomy without sternotomy is described and the early results of the follow-up of patients operated on are analyzed. ⋯ We conclude that the "maximal" transcervical-subxiphoid-videothoracoscopic thymectomy is a safe operative technique, avoiding a sternotomy, performed partly in an open fashion with the extensiveness comparable with the transsternal extended and "maximal" thymectomies. The two-team approach helps to reduce the operative time. However, because of the limited time of follow-up it is too early for the final assessment of the long-term results of this method in the treatment of myasthenia gravis.

Review Comparative Study
Associated factors and trends in outcomes of interrupted aortic arch.
Interrupted aortic arch (IAA) continues to be associated with important mortality, both before and immediately after repair, with ongoing morbidity during follow-up. We sought to determine trends in presentation, management, outcomes and associated factors. ⋯ While improving, outcomes of IAA remain of concern, especially in patients with associated lesions.

Review Comparative Study
Comparison of late results of basic transsternal and extended transsternal thymectomies in the treatment of myasthenia gravis.
The influence of the technique of thymectomy on late results in the treatment of myasthenia gravis remains controversial. ⋯ Late results, both positive and negative, were considerably better in the extended thymectomy group. The difference can be explained by the removal of ectopic foci of the thymic tissue from the neck and the mediastinum in these patients.

Randomized Controlled Trial Comparative Study Clinical Trial
A closed perfusion system with heparin coating and centrifugal pump improves cardiopulmonary bypass biocompatibility in elderly patients.
Cardiopulmonary bypass induces a systemic inflammatory and hemostatic activation, which may contribute to postoperative complications. Our aim was to compare the inflammatory response, coagulation, and fibrinolytic activation between two different perfusion systems: one theoretically more biocompatible with a closed-circuit, complete heparin coating, and a centrifugal pump, and one conventional system with uncoated circuit, roller pump, and a hard-shell venous reservoir. ⋯ The results suggest that a closed perfusion system with a heparin-coated circuit and a centrifugal pump may improve cardiopulmonary bypass biocompatibility in elderly cardiac surgery patients in comparison with a conventional system.
