众所周知,无论是用自体的或异体的游离气管,移植后可完全被吸收产生严重的纤维化,最后导致气管狭窄,丧失通气功能。我们曾经进行如下的动物实验:将狗的气管切除一小段,用盐水冲洗后立即再植于原处。四周后这只狗窒息死亡。解剖证明移植的气管已被吸收,代之以瘢痕狭窄。因此,在气管、支气管外伤后,或肿瘤切除后如何行气管缺损的重建术,保持正常的通气功能,就成为重要的课题之一。近年来,由于肺移植术的初步成功,人 It is well-known that either autologous or allogeneic free trachea can be completely absorbed after transplantation resulting in severe fibrosis, resulting in tracheal stenosis and loss of ventilatory function. We have conducted the following animal experiments: The dog's trachea cut a short period of time, immediately after rinsing with saline replantation in place. After four weeks the dog died of suffocation. Anatomically proved transplanted trachea has been absorbed, replaced by scarring. Therefore, the trachea, bronchial trauma, or tumor resection how to repair the tracheal defects, to maintain normal ventilation function has become an important issue. In recent years, due to the initial success of lung transplantation, people
