The management of bronchial fistula associated with acute lung injury raises two major concerns: (1) high ventilation pressures are necessary for lung recruitment but detrimental for fistula healing, and (2) adequate lung recruitment is prevented by large air leak. Primary surgical closure of bronchial fistula should be attempted but is rarely successful during mechanical ventilation. We sought to evaluate the efficacy of extracorporeal membrane oxygenation associated with lung-protective ventilation in case of failure of conventional management. ⋯ If correctly timed, extracorporeal membrane oxygenation can provide a therapeutic bridge to lung-protective ventilation and allow bronchial fistula healing in case of refractory respiratory failure.

Ross root dilation in adult patients: is preoperative aortic insufficiency associated with increased late autograft reoperation?
The Ross aortic valve replacement (AVR) offers excellent hemodynamic and clinical outcomes in most patients undergoing aortic root replacement. Because of ongoing debate regarding the durability of this procedure, long-term follow-up in a large adult Ross experience might be of interest. ⋯ Preoperative aortic regurgitation was not a significant risk factor for late autograft reoperation in adults. The Ross AVR provides excellent hemodynamics and survival for adults willing to accept a small risk of reoperation as opposed to a life-long risk of thromboemboli and anticoagulation therapy as exist with mechanical aortic prostheses. Reoperation risk for Ross AVR has decreased with Ross annulus sinotubular junction reinforcement replacement of a dilated ascending aorta and postoperative hypertension management.
