NIRS-guided BACP during MHCA allows a safe approach to complex aortic arch surgery. The drop of brain oxygenation values in the contralateral hemisphere during unilateral ACP strongly suggests the routine use of BACP, when circulatory arrest under tepid temperatures is used.

In patients undergoing cardiac surgery the monitoring of pre- and immediate postoperative HLA-DR levels during the first 24 h does not help to predict increased risk for postoperative SIRS/sepsis or infectious complications.

Retrograde aortic dissection type A is a serious complication of thoracic endovascular repair of acute aortic type B dissection. Despite the small number of patients investigated in this study, the frozen elephant trunk technique appears to be a feasible bail-out strategy for the treatment of these acute aortic events.

The management of open chest with the vacuum assisted closure (VAC) system was evaluated in terms of impact on cardiac hemodynamics, respiratory parameters, complications, incidence of wound infection, overall handling and outcome in 22 patients during 2005 and 2008 after cardiac surgery. The decision to leave the sternum open was made electively in all patients at the time of primary operation or reexploration. In four patients the VAC was implanted during the primary operation. In the remainder the VAC was implanted after a mean of five days after the primary operation. The overall mortality rate was 45% (10/22). None of the patients developed a sternal wound infection, nor were there any VAC related complications. Management of open chest with the VAC system can be considered as an alternative to sterile draping. The VAC has no negative impact on cardiac hemodynamics as well as respiratory mechanics. The feared complication of right ventricular rupture and massive bleeding can be effectively prevented. Through the stabilizing of the thoracic cage, the patient can be easily moved and mobilized for nursing reasons and pneumonia prevention. Furthermore, the VAC effectively prevents the contamination of the wound and the mediastinum with potential subsequent infection.
