Growing cava vein anastomosis: comparison of cross-clamping and suture times using VCS metallic clips, interrupted nonabsorbable, or continuous absorbable suturing techniques.

Background: The latest generation in titanium clip application systems, the AnastoClip Vessel Closure System (VCS; LeMaitre Vascular, Burlington, MA), allows surgeons to perform vascular anastomosis more easily and faster than conventional sutures. This system may become the option of choice for vascular reconstruction in pediatric surgery where, as in the case transplant surgery, decreasing vascular occlusion times may influence outcome. The aim of this study was to determine whether VCS metallic clips would allow shorter anastomosis times than conventional interrupted polypropylene or running polyglycolic acid suturing in end-to-end anastomosis performed in the abdominal cava of young pigs.
