The ideal strategy for pulmonary graft preservation remains elusive. Bronchial complications continue to occur after lung transplantation despite advances in operative technique and organ preservation. Airway ischemia of the graft may lead to tissue necrosis, resulting in bronchomalacia, formation of granulation tissue with subsequent strictures, or bronchial dehiscence followed by life-threatening subsequent vascular erosion.1,2 Anatomically, a dual blood supply to the lung consisting of the pulmonary and the bronchial artery systems is provided. During lung graft retrieval, the bronchoarterial system is not preserved selectively and is inevitably interrupted. Although revascularization of the bronchial artery circulation during transplantation has been shown to be beneficial for airway healing in certain patient populations,3 this concept has not been widely accepted in bilateral sequential lung transplantation. Reestablishment of blood flow in the bronchial arteries is technically demanding and has led to inconsistent results. Most centers therefore omit revascularization of the bronchial arteries for
