Tracheal blood flow before and after division of the segmental tracheal blood supply with and without application of a polypropylene spiral prosthesis was measured in dogs by radiolabeled microsphere injection. Ischemia of the central part of the trachea, from the mid-cervical to mid-thoracic regions, was observed immediately after division of the segmental tracheal blood supply with and without polypropylene spiral prosthesis application. On day 3, tracheal blood flow was significantly decreased in the central part of the trachea with and without polypropylene spiral prosthesis application. On day 7, tracheal blood flow was significantly increased throughout the trachea, with no significant differences between animals with and without prosthesis application. There was no evidence of a collateral source of blood supply to the trachea. Surgical division of the segmental tracheal blood supply of the trachea. Surgical division of the segmental tracheal blood supply of the entire trachea is not recommended.
通过放射性微球注射法，在犬类动物中测量了气管节段性血供切断前后、应用和未应用聚丙烯螺旋假体时的气管血流量。在切断气管节段性血供且应用或未应用聚丙烯螺旋假体后，立即观察到气管中央部分（从中颈部到中胸部区域）出现缺血情况。在第3天，无论是否应用聚丙烯螺旋假体，气管中央部分的血流量均显著降低。在第7天，整个气管的血流量显著增加，应用和未应用假体的动物之间无显著差异。没有证据表明气管存在侧支血供来源。气管节段性血供的手术切断。不建议对整个气管的节段性血供进行手术切断。
