We studied the efficacy of polytetrafluoroethylene (PTFE) grafts in the surgical correction of extensive tracheal defects in rabbits. Results showed anastomotic stenosis in 100% of the animals after primary reconstruction when a total of six complete rings were resected. We did not appreciate tracheal stenosis in no animal when we applied a PTFE prosthesis placed around the anastomotic site. Results were not satisfactory upon repairing partial tracheal defect by means of a spindle of PTFE prosthesis. We concluded that the external tutor is useful for the surgical correction of the tracheal stenosis induced after resection of six rings in the cervical tracheal of the animal.
我们研究了聚四氟乙烯（PTFE）移植物在兔广泛气管缺损手术矫正中的疗效。结果显示，当总共切除六个完整气管环进行一期重建时，100%的动物出现吻合口狭窄。当我们在吻合口周围应用PTFE假体时，没有一只动物出现气管狭窄。使用PTFE假体纺锤体修复部分气管缺损时，结果并不理想。我们得出结论，外部支撑物对于手术矫正动物颈段气管切除六个环后引起的气管狭窄是有用的。
