摘要
目的 探索一种安全、快捷的小血管吻合方法。方法 将吻合口管壁两侧 0°和 180°位斜形4 5°对称剪去一小等腰三角形管壁 ,剪去三角形的各边为血管管径的 1/3,使吻合口管壁前后呈梯形对称二等分叶 ,先用两定点缝合法吻合 0°和 180°位叶间 ,而后缝合梯形叶部和梯形叶边。结果 大鼠尾动脉 2 0个吻合口、颈总动脉和股动脉 4 0个吻合口 ,即刻通畅率 10 0 %。大鼠颈总动脉和股动脉吻合口近期通畅率 (2周 )为 10 0 % ,吻合前后血管口径无明显狭窄 (P >0 0 5 )。吻合口经光镜及扫描电镜观察愈合过程良好。临床应用 2 4例全部成功 ,未发生血管危象。结论 该法吻合小血管克服了对端吻合法中两定点吻合时进针困难的缺点 ,最大限度地减少了血管内膜损伤机会 ,避免了小血管吻合时误穿对侧管壁的弊端 ,确保吻合口管壁完全外翻 ,内膜平整对合。该法操作简单 ,吻合速度快 ,通畅率高 ,可减少血管危象发生 。
Objective To investigate a safe and prompt anastomosis of small vessel. Methods According to diameter, the triangular wall of the bilateral vascular wall was excised and cut off two trapezoid lobulated flaps, two flaps were sutured. Results 20 rats tail artery and 40 arteries of caroitid and rat limbs all unobstructed at once after anastomosis. 40 arteries of rat necks and limbs were all unobstructed after two weeks of anastomosis. The internal diameter of anastomosis edge of rat carotid and femoral before and after anastomosis were not stenosis( P >0 05). 8 cases of injury of ulna and radial artery were unobstructed after anastomosis and 11 cases of finger replantation and 5 cases of free flap received good results. Conclusion The healing process of anastomosis edge is good under scanning electronic microscope.It can decrease the vessel crisis after microvascular anastomosis and increase the unobstructed rate.
