Vein and artery growth after anastomosis with vascular closure staple clips vs interrupted polypropylene suture: application in pediatric vascular surgery

Angiographic, ultrasonographic, and macroscopic assessment of aortic growth after VCS clips, interrupted polypropylene, or running polyglycolic acid anastomosis

“…This time is enough for aortic vasospasm to disappear. These results are similar to our previously published data in different vascular territories, [7][8][9][10][11].…”

“…As in previous works [7][8][9][10][11], we found statistically significant longitudinal growth in clip-operated arteries (Fig. 4) as well as in the other 3 studied groups (polypropylene, polyglycolic acid, and control).…”

“…No report has been found describing such significant growth after anastomosis. Only in prior studies conducted by our research team have we found comparable growth results [7][8][9][10][11]. Chang et al [14] use polypropylene in growing arteries, describing, in contrast to our experience, the existence of slight vascular stenosis after growth.…”

“…To assess the VCS clips in this setting, they were compared with 2 conventional suturing materials and techniques, namely, interrupted polypropylene (nonabsorbable) and running polyglycolic acid (absorbable). Based on previous experiences, not only should the clips allow for a comparable growth, but results may be improved when compared with the other 2 techniques [7,8,11]. In the case of interrupted nonabsorbable suture, this previously reported improvement would be attributable to the lack of exogenous material invading the inner vascular surface when using VCS clips.…”

“…Previous studies (Calles et al [8], Calles-Vázquez [7,[9][10][11], and Lima et al [12]) performed in peripheral arteries and veins have demonstrated that the latest vascular clip applier, the vasular closure stapler (VCS), decreases surgical time and allows longitudinal and transversal growth with correct anastomotic healing without causing any flow disturbance in growing vessels.…”
