简要总结
Perforator vessels are those where the source artery is deep and the branch that carries blood to the fasciocutaneous tissues passes through the overlying deep fascia.
Soft tissue defects in the lower extremity, especially distal third of leg, present a challenge to reconstructive surgeons due to lack of reliable local flaps, conventional reconstructive options include split skin grafting, local random fasciocutaneous flaps, cross leg fasciocutaneous flap, pedicled muscular or musculocutaneous flaps or microvascular free tissue transfer. All these procedures have their limitations and associated morbidity at donor site
详细描述
Taylor and Palmer defined an angiosome as a three-dimensional vascular territory supplied by a source artery and vein through branches for all tissue layers between the skin and the bone, and showed that between neighboring angiosomes there are choked and true anastomotic arteries.
Koshima and Soeda in 1989, described an inferior epigastric artery skin flap without the rectus abdominis muscle for reconstruction of floor of mouth, began the era of perforator flaps.
The big popularity gained by the local perforator flaps was due to their main advantages: 1) Sparing of the source artery and underlying muscle and fascia, 2) Combining the very good blood supply of a musculocutaneous flap with the reduced donor-site morbidity of a skin flap, 3) Replacing like with like, 4) Limiting the donor-site to the same area, 5) Possibility of completely or partially primarily closure, 6) Technically less demanding, because they are microsurgical procedures, but without microvascular sutures, 7) Shorter operating time.
