We attempted to transplant a vein graft to normal lymphatics (LVL) to investigate whether it could survive and remain joined to the lymphatics as the environment changed. A total of 152 rabbits were divided into 3 groups. Group 1 was an LVL saline-irrigated group (n = 40), with a patency rate of 52.5%. Group 2 was an LVL nonirrigated group (n = 34), with a patency rate of 29.4%. Group 3 was an LV group (n = 78), with a patency rate of 32%. All specimens were examined under either light microscope or scanning electron microscope. The data indicated that an LVL anastomosis is practical and that preanastomotic irrigation can improve the patency rate. In both the LVL and the LV groups, endothelial regeneration, originating from the adjacent endothelium, commenced within 1 week after the anastomosis, with complete healing within 3 to 4 weeks. The vein graft tended to become "lymphaticized." Thrombosis was the main cause of obstruction. The patency rate can be increased by irrigation of the ends with saline before performing the anastomosis. The graft intima must be kept intact, the nutritive blood vessels of the lymphatics must be preserved, and the flow must be artificially increased soon after the anastomosis.
我们试图将静脉移植物移植到正常淋巴管（LVL）上，以研究其在环境变化时能否存活并与淋巴管保持连接。总共152只兔子被分为3组。第1组是LVL盐水冲洗组（n = 40），通畅率为52.5%。第2组是LVL未冲洗组（n = 34），通畅率为29.4%。第3组是LV组（n = 78），通畅率为32%。所有标本均在光学显微镜或扫描电子显微镜下检查。数据表明，LVL吻合术是可行的，吻合前冲洗可提高通畅率。在LVL组和LV组中，源自相邻内皮的内皮再生在吻合后1周内开始，3至4周内完全愈合。静脉移植物倾向于“淋巴管化”。血栓形成是阻塞的主要原因。在进行吻合术前用盐水冲洗末端可提高通畅率。移植物内膜必须保持完整，淋巴管的营养血管必须保留，并且吻合后必须尽快人为增加血流量。
