摘要
目的:对犬自体肋骨肋间肌肌瓣环再造气管的形态及病理学变化进行观察。方法:将犬的第3肋骨修整卷曲成五边形,用此肋骨肋间肌肌瓣环再造气管替代胸内部分气管,观察术后再造气管的形态及病理学变化。结果:术后再造气管稳定性好,血液供应较好,内径、截面积较大,基本能够维持气管的通气功能。镜下观察可见:术后早期,再造气管内膜可见大量新生毛细血管形成的炎性肉芽组织;术后中晚期肋骨卷曲折角处可见新生骨组织,正常气管与肋间肌吻合口交界区出现移行的柱状上皮。结论:犬肋骨肋间肌肌瓣环再造气管的形态达到气管的管道形态,再造的气管组织能够存活。
Objective:To observe the morphological and pathologic changes of reconstructed trachea with ribs and intercostal muscles ring in dogs.Methods:The 3rd rib of dog was curled into pentagon and part of the trachea of dog was replaced by this ribs and intercostal muscles ring.The morphological and pathologic changes of reconstructed trachea was observed after operation.Results:The reconstructed trachea was stable after operation, its blood supply was well,the internal diameter and the section area of the recontructed trachea were comparatively large. The reconstructed trachea could maintain the ventilation function.The reconstructed trachea was observed under microscope:At early stage after operation, phlogotic granulation tissue with a great quantity neonatal capillaries could be seen in the tunica intima of reconstruced trachea;At middle and advanced stage after operation, neonatal osseous tissue could be seen at the angle of curled ribs, the anastomotic stoma of normal trachea and reconstructed trachea could be seen transitional columnar epithelium.Conclusions:The reconstructed trachea with ribs and intercostal muscles ring has the shape of normal trachea,and the reconstruted trachea can survive.
