The ideal solution to the bronchial healing problems in lung transplant would be the reconstruction of the bronchial arteries at time of transplantation. The problems with this approach are essentially technical being difficult to identify and preserve the bronchial arteries in humans. The purpose of this paper is to report our experience with an experimental model in dog to easily identify and preserve bronchial circulation in single lung transplantation. The technique is based on the preservation during harvesting of the aortic origin of the first five couples of arterial orifices. Identification of the orifice(s) connected with the bronchial circulation is carried out by the backflow which takes place from the pulmonary circulation after organ reperfusion is resumed. The identified orifice(s) is then anastomosed to the descending recipient aorta, tangentially clamped.
肺移植中支气管愈合问题的理想解决方案是在移植时重建支气管动脉。这种方法的问题本质上是技术方面的，即在人体中难以识别和保留支气管动脉。本文的目的是报告我们在犬类实验模型中的经验，以便在单肺移植中轻松识别和保留支气管循环。该技术基于在摘取过程中保留前五对动脉口的主动脉起源。与支气管循环相连的口通过器官再灌注恢复后从肺循环发生的逆流来识别。然后将识别出的口与受体降主动脉进行吻合，并进行切线钳夹。
