A. Absorbable natural suture
B. Absorbable synthetic suture
C. Non-absorbable natural suture
D. Non-absorbable synthetic suture
Polyglycolic acid (Dexon) and Polygalactin 910 (vicryl), Polyglyconate, Glycomer 631, Polyglytone 6211, Polydioxanone (PDS) are synthetic absorbable suture.
Polygalactic acid (Dexon) is green dyed and Polygalactin 910 (vicryl) is purple dyed while remaining are undyed.
Polygalactin (coated vicryl) is braided. It is commonly used for bowel anastomosis, as a general tie for vessels and as a subcuticular suture for skin. It has 75 percent of its strength at 2 weeks and 50 percent at three weeks. It causes a minimal tissue reaction and is very close to being the ideal suture for almost all purposes.
Polyglyconate has some some superior strength. It retains 75 percent of original strength at two weeks of post-implantation. Advantages over other sutures, such as improved handling properties, lacks memory, passes easily through tissues and demonstrates good strength. Absorption is essentially complete by 180 days.
Polydioxanone (PDS) suture has greater pliability than polypropylene suture and has greater strength than that of other monofilament sutures. In the body, Polydioxanone suture retains its strength for longer periods than other synthetic absorbable sutures.
