dc.description.abstract | Tissue reaction to suture materials depends mainly
on how the polymer they are composed of interacts with
the tissues. There are few in vivo studies evaluating the suture
material modifications resulting from its interaction with
tissues. This paper aimed to study rat subcutaneous tissue
reaction to irradiated polyglactin 910, polydioxanone, poliglecaprone
25 and chromic gut and its correlation with the
ultra-structural alterations the materials undergo. The histological
alterations were studied on the 1st, 2nd, 3rd, 7th
and 14th day after suture implantations. In these periods, the
materials were removed from the tissues and their surfaces
were analyzed by scanning electron microscopy. Irradiated
polyglactin 910 stimulated the formation of multinucleated
giant cells and its filaments underwent cleavage and dissolution.
In potydioxanone, a few inflammatory cells and scar
fibrosis was observed, and triangular cracks appeared on its
surface. Around the poliglecaprone 25, a diffused infiltration
of a few mononuclear cells and fibrosis was recorded and
formation of craters was observed on its surface. Chromic
gut induced necrosis and granulation tissue and underwent
dissolution in the tissues during the studied periods. In this
study, it was observed that suture materials induced differentiated
tissue reactions and morphologic surface changes,
suggesting that indications should be individualized. | pt_BR |
