Answer: D. Degraded by enzymatic degradation
Catgut-
Types- plain
Raw material- Collagen derived from healthy sheep or cattle
Tensile strength retention in vivo- Lost within 7-10 days.Marked patient variability. Unpredictable and not recommended.
Absorption rate- Phagocytosis and enzymatic degradation within 7- 10 days
Tissue reaction- high
Contraindications- Not for use in tissues that heal slowly and require prolonged support. Synthetic absorbable is superior.
Uses- Ligate superficial vessels, suture subcutaneous tissues. Stomas and other tissues that heal rapidly.
