小血管吻合技术手术有哪些方法 武乃旺 山西省肿瘤医院 小血管吻合技术手术有：1、端端直接缝合，这个是由于端端血管靠近相当的吻合；2、端侧缝合法，这个由于端端血管靠近相差比较大的，难以进行端端吻合或者是为了保留受区血管的连续性，不影响远端血供者；3、套叠缝合法，适用于管径稍有差异的吻合处，应该注意要按照血流的方向套叠，套入段的血管长度应是血管外径的长度或者是略大于血管外径；4、剪开套叠缝合法，这个方法适用于断端吻合口有差异的，而血管的粗细与血流方向相反。 What are the methods of small vessel anastomosis The techniques of small vessel anastomosis are as follows: 1, This is due to the close anastomosis of the end-to-end vessels; 2. End to side stitching, Because there is a big difference in the proximity of the end-to-end vessels, It is difficult to perform end-to-end anastomosis or to preserve the continuity of blood vessels in the recipient area, It does not affect the distal blood donor; 3. Overlap seam method, It is suitable for the joint with slightly different pipe diameter, Attention should be paid to overlap according to the direction of blood flow, The length of the vessel in the insertion segment should be the length of the outer diameter of the vessel or slightly larger than the outer diameter of the vessel; 4. Cut the sleeve and fold the seam, This method is suitable for the different anastomoses, The thickness of blood vessels is opposite to the direction of blood flow.
