  • Title: Vein and artery growth after anastomosis with vascular closure staple clips vs interrupted polypropylene suture: application in pediatric vascular surgery.
    Author: Calles-Vázquez Mdel C, Viguera FJ, Sun F, Usón JM, Usón J.
    Journal: J Pediatr Surg; 2005 Sep; 40(9):1428-35. PubMed ID: 16150344.
    Abstract:
    BACKGROUND/PURPOSE: Alternatives are still being sought in vascular surgery to address the problem of arrested growth after anastomosis in growing vessels, and opinions differ widely regarding the most suitable technique. This study compared vascular growth and permeability after anastomosis using the latest-generation vascular closure staple (VCS) system and the conventional suture technique to ascertain which approach yielded better results. METHODS: Thirty 55-day-old lambs underwent end-to-end anastomosis of the carotid artery and jugular vein. Serial ultrasonography and angiography were carried out over the ensuing 6-month growth period, after which lambs were euthanized. RESULTS: Both VCS clips and polypropylene suture allowed longitudinal and transverse vessel growth; however, longitudinal growth was significantly greater in clip-closed vessels than in either sutured or untreated vessels. CONCLUSIONS: The results obtained for vascular growth and permeability suggest that VCS clips may provide a suitable alternative to conventional suture in pediatric vascular surgery.
