End-to-side-anastomosis in the dog using the 3M precise microvascular anastomotic system: a comparative study.

In this study, the patency rates, microscopic characteristics, and intraluminal dimensions of end-to-side anastomoses in the dog were compared with those of a conventional interrupted suturing technique, using the 3M precise microvascular anastomotic system. The anastomoses included end-to-side repairs of the saphenous artery to the femoral artery, as well as the saphenous vein to the femoral vein. The patency and microscopic characteristics of the two techniques were similar, but the mechanical coupling system required much less time than the suture technique to complete the vascular anastomosis.
