Sutureless vascular anastomosis: the VCS clip

Non-penetrating, arcuate-legged clips facilitate vascular reconstructions and significantly reduce the incidence of anastomotic neointimal hyperplasia. Though originally developed as a microvascular-approximating instrument, by far the largest application has been for hemodialysis vascular access. Long-term studies comparing suture to clip for access creation have demonstrated the clear technical and biological superiority of the clip for this procedure. This "sutureless" vascular anastomotic technique is more demanding than conventional suturing, requiring precise vessel preparation and supervised training.
