A new technique for performing a microvascular end-in-end or "sleeve" anastomosis is described. The new method utilizes two asymmetrically placed, looped sutures that do not enter the active lumen or breach the active intima. It has advantages over previous methods because it consistently saves time and because of the decrease in the number of possible technical complications. In 77 anastomoses performed in white rats by different surgeons, including a few inexperienced students of microsurgery, there was only one failure (24-hr patency). After eight practice anastomoses, the average time taken from vessel division to final clamp release in 30 procedures was 7 min 33 sec, with a standard deviation of 1 min 45 sec. The sleeve anastomosis performed by this method has shown itself to be as reliable as a conventional end-to-end suture method and has the advantages of significant time saving and minimization of intimal trauma. The anastomosis of vessels of differing sizes is facilitated by the conformation of this new method and the technique has clinical potential in the anastomoses of interposition vein grafts and in human intravenous anastomoses.
本文描述了一种进行微血管端端或“套入式”吻合的新技术。新方法采用两根不对称放置的环形缝线，不进入活动管腔或损伤活动内膜。它比以前的方法具有优势，因为它始终能节省时间，并且可能出现的技术并发症数量减少。在不同外科医生（包括一些经验不足的显微外科学生）对白色大鼠进行的77次吻合术中，仅有一次失败（24小时通畅）。经过8次练习性吻合后，30例手术中从血管离断到最终松开血管夹的平均时间为7分33秒，标准差为1分45秒。用这种方法进行的套入式吻合已证明与传统的端端缝合方法一样可靠，并且具有显著节省时间和使内膜创伤最小化的优点。这种新方法的结构有利于不同大小血管的吻合，该技术在静脉移植吻合和人体静脉吻合方面具有临床应用潜力。
