PGA is synthetic absorbable, multifilament (braided), suture made from polyglycolic acid. Thread is coated with biocompatible polycaprolactone and calcium stearate. Thanks to its smoothness it penetrates tissues without much friction and with minimal tissue reaction. As it is a multifilament thread it is highly elastic. Atraumatic combinations of PGA are available with different types of single and double stainless steel needles. Thread can be colorless or died violet (using dyestuff C. I. Solvent Violet 13). With lapse of time, gradual loss of strength and process of absorption is visible. Absorption of PGA sutures occurs by means of hydrolysis.
Approximate % original Breaking Strength Retention:
- 80% after 14 days from implantation,
- 50% after 21 days from implantation,
- 20% after 28 days from implantation.
Total absorption is ended after 60 - 90 days.
Atraumatic combinations of PGA are available in a range of gauge sizes and lengths, non-needled or attached to different types and sizes of single and double stainless steel needles. Violet colour is used on single and collective packaging.
PGA complies with the requirements of European Pharmacopoeia for sterile, absorbable, braided sutures.
