摘要
目的观察自体腹膜管替代血管后内膜的超微结构变化，研究自体腹膜管作为一种新型替代血管材料的可行性。方法选取１４只狗的自体带腹直肌后鞘的腹膜，制成腹膜管并间置于切断的腹主动脉间。通过移植后不同时期连续扫描电镜观察腹膜管移植后的内膜变化。结果在移植后的中期，腹膜管内膜开始修复；在移植的后期，膜腹管内膜有血管内皮样细胞长入管腔并覆盖于内膜上。结论自体腹膜管可以作为一种新型的血管替代材料。
Objective To study the feasibility of autogenous peritoneal tube as a new type of vessel replaced material by observing the intimal ultrastructure change. Methods In 14 dogs, the interposition graft in the abdominal aorta was replaced by the autogenous peritoneal tube, which was composed of the peritoneum with the posterior sheath of the rectus muscles. After transplantation, the autogenous peritoneal tubes were examined and photographed using a scanning electron microscope in different periods. Results The mesothelial cell of the autogenous peritoneal tube began to repair at 2 months postoperatively and the autogenous peritoneal tubes were covered with the vessel endothelial like cell at the end of the study. Conclusion The autogenous peritoneal tube may serve as a new type of material for replacement of the vessels. peritoneum/transpl; aorta, abdominal/surg; dogs
