摘要
目的 对修整成不同形状肋骨的骨肌瓣环替代胸内部分气管进行对比观察。方法 将犬的第 3肋骨修整卷曲成三角形、四边形和多边形 ,用附着不同形状肋骨的骨肌瓣环替代胸内部分气管。结果 折曲成三角形肋骨的骨肌瓣环稳定性最好 ,但内径、截面积小 ,易发生狭窄。四边形肋骨环稳定性最差。多边形肋骨环的内径最大 ,稳定性较好 ,腔内再配合硅胶管支架 ,再造气管的性能更好。结论 犬的肋骨肌瓣环可以替代胸内部分气管 ,其中附有多边形肋骨的骨肌瓣环性能最好。
Objective To compare the effect of several types of rib rings with intercostal muscles for the replacement of trachea in thorax.Methods\ The surface layer of the third rib of dogs were ripped off and curved into triangular, quadrilateral and palygonal form. These three types of rib rings with intercostal muscles were used to replace a segment of trachea in thorax.Results\ The stability of triangular rib ring was very well, but stricture of ring were often happened because of its smaller internal diameter. These stability of quadrilateral rib ring was the worst. The polygonal rib ring presented the biggest diameter and good stability compared to the other two kinds of rings. If silicone tube was supplemented in the polygonal rib ring, the quality of artificial trachea was excellent.Conclusion\ The rib rings with intercostal muscles are successfully used for replacing the defect of trachea in canine thorax. The polygonal rib rings have the best quality in the three types of rib ring for tracheal replacement.
