Sutureless Vascular Anastomoses by Polydioxanone Connector

Abstract

Usually a single end-to-end anastomosis on a middle-size vessel cannot be performed in less than twenty minutes with either separate or continuous suture technique. For easy and quick anastomoses the authors studied 12 dogs with a sutureless concept. With this method proximal and distal ends of a vessel were joined by means of a polydioxanone tube connector. The sutureless procedure took approximately five minutes to complete. Six months after the operation the anastomoses were examined and more than 41% of the vessels were found patent. The authors' opinion is that, if polydioxanone tube is prepared more properly, the rate of patency will be higher than this.

Crystallization study on absorbable poly(p-dioxanone) polymers by differential scanning calorimetry

“…PDS is a synthetic absorbable material, which is typically made by ring‐opening polymerization of the lactone monomer, p ‐dioxanone (also known as 1,4‐dioxanane‐2‐one) 17. Polymers and copolymers based on p ‐dioxanone have became increasingly important in a variety of biomedical applications16, 18 due to their in vivo degradability, low toxicity, softness, and flexibility. For instance, these important features allowed PDS to be made into a synthetic absorbable monofilament suture, with handling characteristics needed by surgeons.…”
