title: Evolution of staples and clips for vascular anastomoses.
abstract: Because of the development of less invasive surgical techniques, there is an increasing demand for vascular anastomosing techniques that require less exposure of the operating field. This paper reviews the most important representatives of staples, clips, and other mechanical devices for vascular anastomosing described over the last five decades. This report is organized in three parts: (1) the history of clipping and stapling devices, (2) development of the Vessel Closure System (VCS) clips, and (3) current and potential status of mechanical vascular anastomotic devices. A Medline literature search was conducted and publications on the use of staples and/or clips for the creation of vascular anastomoses identified with extensive cross-referencing. The first literature description of a mechanical vascular stapling device was by Gudov in 1950. This and other reports from the Soviet Union stimulated brisk, competitive development of vascular anastomotic devices in Europe, North America, and Japan. Fasteners included staples, penetrating pin-rings, or toothed stainless steel clips, none of which gained acceptance because of their complexity and inability to facilitate end-to-side anastomoses. A more convenient and less traumatic anastomotic system (VCS Clip applier system) was introduced into clinical practice in 1995. This system differs from staples in that it is non-penetrating. A wide variety of reports have described the advantages, both technical and biological, that clips provide over conventional needle-and-suture, particularly for the construction of vascular access for hemodialysis. A steady evolution of mechanical vascular anastomotic devices has sought to eliminate the technical and biological disadvantages of conventional suturing. Although the conventional hand-sewn, overcast non-absorbable suture remains the "gold" standard, newer techniques such as the non-penetrating arcuate-legged VCS clips are gaining acceptance as a useful addition to the vascular surgeons' armamentarium.
