摘要
目的研究人造血管在兔腓肠肌腱损伤修复术后套接预防粘连的作用。方法选择大耳白兔14只,随机分为两组,一组腓肠肌腱切断后单纯吻合,另一组套接人造血管后吻合,均给予外固定。6周后去除外固定,测量关节活动度,对照评价。结果对照组踝关节活动度平均值为22.50°±9.35°,使用e-PTFE组关节活动度值为96.67°±15.71,两样本行t检验,t=9.9381,P<0.001,具有统计学意义。病理切片显示,人造血管里新生内膜,肌腱愈合良好,无粘连形成。结论使用人造血管可以有效预防兔腓肠肌腱损伤修复后发生的粘连,且对肌腱愈合无影响。
Objective It is a report on the repair effect of a kind of man-made blood-vessel（expended polytetrafluoroethylene,short for e-PTFE）in preventing adhesion after the injury of rabbit′s gastrocnemius.Methods Choose 14 Japanese White Rabbits and divide into 2 groups randomly.After cutting rabbit′s gastrocnemius,simply anastmose these of one group.Those of other group are wrapped with e-PTFE and then be anastomosed.Both have external fixation,and are taken off after 6 weeks.Measure the range of motion of two groups and contrast.Results The average ROM of control group is 22.50°±9.35°.That of e-PTFE group is 96.67°±15.71.Conclusion The T-test of two samples is 9.9381,and P0.001,which are considered statistically significant.Pathological sections show that new intima emerges in e-PTFE,and healing of gastrocnemius is well without adhesion.
