Arterial anastomose with polydioxanone and polypropilene suture. Comparative study in dogs

Abstract

The objetive of this study was to compare the effects of the absorbable polidioxanone suture to the nonabsorbable polypropylene suture, in end-to-end anastomoses, using dog’s femoral arteries. Twenty dogs were separated in two groups for observation on the 7^th and 30^th post-operatory day. Each dog had its femoral arteries seccioned and then aproximated one side with separate stitches of polidioxanone 6-0 suture, and the other side with polypropylene 6-0 suture. For the statistical studies Fisher, Mac nemar, Wilsoxon, Mann-Witney and T of Student tests (a ≤ 0,05) were carried out. No significant differences were observed between the sutures employed in clinical evolution. The results obtained in the arteriographic and macroscopic avaliation were similar, as well as the morphological histologic analysis. In the morfometric histologic analysis the polypropylene suture showed a significantly higher number of foreign body giant cells reaction, comparing to the polydioxanone suture on the 7^th or 30^th post-operatory day. The results allow us to conclude that, in spit of the higher reaction of foreign body observed with the polypropilene suture, the polydioxanone suture showed similar results in dog’s arterial anastomoses.
