dc.description.abstractBio-absorbable sutures are largely used to hold and wind tissues together in good apposition until completing the healing process, without needing future removal. There are some materials commonly used for these sutures, such as polyglycolide, polylactide, poly(ecaprolactone), mucosa or beef intestines. Some of these materials have marked or moderate tissue reaction, like mucosa or beef intestines, and could not be used for some delicate applications, like braiding brachytherapy seed strands. The best option for this application is Vicryl sutures, trade mark of Johnson&Johnson company. Vicryl has a bio-absortion time still a little long, for brachytherapy application, but it could be accelerated imparting a dose of ionizing radiation in the strand, before using it. In this work, it is shown the procedure where small hanks of Vicryl wires (fifteen centimeters unrolled), surgical diameter number 7-0 (~50 mm), were inserted into rats underskin and removed for mechanical and histological evaluation after 15, 30 and 60 days. Wire samples were irradiated with gamma doses of 10, 25 and 50kGy, besides those non-irradiated. Preliminary mechanical evaluation was carried out in a EMIC DL 2000 machine, using NBR 13904 standard normative test. Fifty grays caused great degradation on wires, preventing any traction evaluation. Small doses are promising for accelerating bio-absortion and the samples mechanical tests results will be the scope of a future work.
