The minimally invasive reversed Z sternotomy is a surgical approach for aortic valve operations that provides an excellent view of the aortic root and allows access to the right atrium. It confers the advantages of preservation of the sternocostal articulations and both internal thoracic arteries with no need to enter either pleural cavity. It facilitates aortic and atrial cannulation for cardiopulmonary bypass and allows access for a superior pulmonary vein cardiac vent.

Although surgical resection is accepted widely as first-line therapy for pulmonary metastases, few data exist on the surgical treatment of recurrent pulmonary metastatic disease. In a retrospective study, we analyzed patients who were operated on repeatedly for recurrent metastatic disease of the lung with curative intent over a 20-year period. ⋯ Although patients with different histologic tumor types were included, the study population appeared to be homogeneous in terms of survival benefit and prognostic factors, and it probably represented the selection of biologically favorable tumors in which histology, size, number, and laterality are of minor importance. We conclude that patients who are persistently free of disease at the primary location but who have recurrent, resectable metastatic disease of the lung are likely to benefit from operation a second, third, or even fourth time.

Reexploration of the mediastinum for bleeding is required in 3% to 7% of patients after cardiac operation, with many proving to have no surgically correctable cause. In spite of a "negative exploration," the bleeding often ceases. We propose the hypothesis that such a negative exploration can be therapeutic by reducing marked fibrinolytic activity in the mediastinal cavity. ⋯ Our data confirm that fibrinolytic activity can be extremely high in the mediastinum in response to clot formation. This may explain the hemostatic effects of a negative reexploration, where irrigation and the removal of clots may reduce the fibrinolytic process; this may allow the bleeding ends of capillaries and small vessels to thrombose. Decreased levels of alpha2-antiplasmin observed suggest that lysine analogs, such as epsilon-aminocaproic acid, may have a beneficial role when locally delivered into the mediastinum.

A case of traumatic right lung herniation to an area of anterior costal sternal separation and right hemothorax is presented. Application of a thoracoscopic approach to a traumatic lung hernia of the chest wall in this case is discussed.
