Polypropylene suture (Prolene)
Synthetic non-absorbable monofilament suture made of polypropylene, an inert material with very low tissue reactivity; often dyed blue to aid visibility.
How it is used
It is the reference suture for vascular and cardiac anastomoses, owing to its smooth glide through tissue and minimal inflammatory response.
Clinical tip
It retains tensile strength essentially indefinitely, without significant in vivo degradation; being a monofilament with memory, it requires more knot throws than braided sutures and can cut through tissue if over-tightened.
