Polydioxanone (PDO) monofilament synthetic absorbable, sterile surgical
suture is prepared from the polyester, poly(p-dioxanone).
Polydioxanone (PDO) exhibits
- Extended holding strength, maintains tensile strength for up to six
- Excellent handling, exceptional suppleness, and good knot security.
- Non-wicking, which eliminates bacterial migration along suture line.
- Violet color for better visibility during
Polydioxanone monofilament synthetic absorbable suture is indicated
for use in soft tissue approximation, including use in pediatric
cardiovascular and ophthalmic procedures. Polydioxanone suture is not
indicated in adult cardiovascular tissue, microsurgery, and neural tissue.
This suture is particularly useful when the combination of an absorbable
suture and extended wound support (up to six weeks) is desirable.
PDO synthetic absorbable suture elicits a minimal acute
inflammatory reaction in tissues, followed by gradual encapsulation of the
suture by fibrous connective tissue. Progressive loss of tensile strength
and eventual absorption of PDO sutures occurs by means of hydrolysis.
Subcutaneous tissue implantation studies in rats indicate PDO
suture retains approximately 75% of initial tensile strength at 2 weeks,
65% at 4 weeks and 50% at 6 weeks post implantation.
Absorption begins as a loss of tensile strength without appreciable
loss of mass. Absorption of PDO sutures is minimal until about the 60th
day after implant and is essentially complete within 6 months.
