Abstract：
BACKGROUND: Anastomotic microvascular device has gained popularity in reconstructive microsurgery over the last two decades. A systematic literature search has been carried out in the use of the venous coupler device in microsurgery to assess its impact on patency rate in microsurgery.
METHODS: Using key words related to the topic, a literature search of major databases was carried out. Selection was undertaken on two level screening. From the literature search 53 potential articles were identified. Of these 13 met both levels of screening for the final critical analysis.
RESULTS: A total of 2976 venous anastomoses with coupler device were carried out in the 13 studies with a combined thrombosis in 46 veins reported, giving an average 98.5% patency and a variation in thrombosis rate ranging from 0 to 3%.
CONCLUSIONS: The venous coupler device serves as a powerful instrument in microsurgery by achieving high patency rate. More importantly the data suggests less variation in thrombosis rate compared to hand-sewn venous anastomosis.

摘要：
背景：在过去的二十年中，吻合微血管装置在重建显微外科手术中越来越受欢迎。在显微外科手术中使用静脉耦合器装置进行了系统的文献检索，以评估其对显微外科手术通畅率的影响。
方法：使用与主题相关的关键词，对主要数据库进行了文献检索。在两级筛选中进行选择。从文献检索中确定了53篇潜在文章。这13个满足了最终关键分析的两个筛选水平。
结果：在报告的46条静脉合并血栓形成的13项研究中，共进行了2976次静脉吻合术，平均通畅率为98.5％，血栓形成率的变化范围为0％至3％。
结论：静脉耦合器装置通过实现高通畅率而在显微外科手术中用作强大的工具。更重要的是，数据表明与手工缝制静脉吻合术相比，血栓形成率的变化较小。
