Sutures

Suture

Is the stand of material used for sewing by bringing tissue together and holding them until healing has taken place.

 

Tie

Is a material to tie around a blood vessel to occlude the lumen.

 

Monofilament Suture

• Made of a single atrand of material
  
• Less resistant when pass through tissue
  
• Cause for infection less
  

 

Multifilament Suture (braided)

• Made by several filaments strands together
  
• Cause for infection higher
