Angiosomes and wound care in the diabetic foot.

Successful foot and ankle reconstructions require a detailed knowledge of vascular anatomy. This knowledge becomes all the more important in diabetic patients because of healing complications and high incidence of peripheral vascular disease; it allows foot and ankle surgeons to design safe exposures and vascular surgeons to choose effective revascularization strategies. The angiosome concept separates the body into distinct threedimensional blocks of tissue fed by source arteries. This article focuses on the surgical implications of angiosomes of the foot and ankle and their arterial-arterial connections.
