Graft (surgery)
MeSH D019737

Grafting refers to a surgical procedure to move tissue from one site to another on the body, or from another person, without bringing its own blood supply with it. Instead, a new blood supply grows in after it is placed. A similar technique where tissue is transferred with the blood supply intact is called a flap. In some instances a graft can be an artificially manufactured device. Examples of this are a tube to carry blood flow across a defect or from an artery to a vein for use in hemodialysis.

Types of grafting[edit]

The term grafting is most commonly applied to skin grafting, however many tissues can be grafted: skin, bone, nerves, tendons, neurons, blood vessels, fat, and cornea are tissues commonly grafted today.

Specific types include:

Reasons for failure[edit]

  • Hematoma (a collection of blood) development when the graft is placed over an active bleed
  • Infection
  • Seroma (a collection of fluid) development
  • Shear force disrupting growth of new blood supply
  • Inappropriate bed for new blood supply to grow from, such as cartilage, tendons, or bone
