【摘要】 目的探讨吻合显微细小血管更理想、安全、快捷的方法。方法大白鼠40只,左侧股动脉后壁和前壁正中各缝合1针作为定点牵引,蘸胶粘接法端-端吻合为实验组,右侧股动脉行常规针线法端-端吻合为对照组,取2只动物两侧股动脉做吻合口耐压实验,其余动物分别于术后1周、2周、3周、4周取血管标本,采用光学显微镜和扫描电镜观察吻合口部愈合情况。结果两侧血管全部吻合通畅,粘接法用时(12±2min)比针线法(1 8±3min)缩短1/3,粘接法吻合口耐压(300mmHG)优于针线组,吻合口电镜观察粘接法内膜更为平整、光滑。结论定点缝线牵引蘸胶粘接法端-端吻合显微细小血管快速、安全、效果可靠,具有较好临床应用前景。更多还原

【Abstract】 Objective Toexplore an ideal and fast way of Microvascular anastomosis.Methods Anastomosis of both femoral arteries were performed in 40 rats.Life side of the arteries were anastomsed with medical adhesive.Right side of the arteries as comparise were anastomsed with suture.Biopsy was performed in two groups of rats at different time intervals postoperatively,and the specimens were examined under light microscopy scanning electron microscopy(SEM).Results There were no difference in patency between the two techniques.The average anastomotic time for suture was about 18 minuters,while for the adhesive was 12 minuters.SEM of the anastomotic site revealed major differences between sutured and adhered groups.Conclutions Medici adhesive microvascular anastomosis technique is fast and reliable.更多还原
