The flap used for lower-extremity coverage is described as being transferred with what property?

• A. It remains attached to its original blood supply
• B. It is a graft without blood vessels
• C. It is a pedicled flap
• D. It is transferred with its own blood supply

Answer: (D)

Transferring tissue with its own blood supply refers to a free flap. This means the flap is moved from its donor site with its vascular pedicle intact and then reconnected to blood vessels at the recipient site, restoring circulation through microvascular anastomosis. This approach provides a robust, independent blood supply necessary for reliable healing in lower-extremity coverage, especially when local tissue is deficient or poorly vascularized. This differs from a graft, which has no its own vessels and relies on the recipient bed for blood supply, and from a pedicled flap, which remains attached to its original blood supply and is not fully detached and revascularized at the new site.
