Abstract
This article summarizes surgical procedures for preservation of the foot in diabetic patients with peripheral artery disease. Distal bypass surgery performed to perigeniculate arteries and to an isolated ‘blind’ popliteal segment with visible collaterals can be performed with limb salvage rates close to what can be achieved with standard bypass to crural arteries. This is also the case when performing bypass to the dorsalis pedis artery. Bypass to the medial or lateral plantar artery or to the lateral tarsal artery is associated with a relatively high rate of early occlusion, but in the patients who have persistently open grafts, limb salvage is common. The use of an arteriovenous fistula as an adjunct to distal bypass surgery does not improve prognosis. Venous arterialization, either creating retrograde perfusion of the superficial or of the deep veins of the foot has been successful in several cases although it is difficult to predict which patients will benefit. Reconstructive surgery is often performed in a multidisciplinary team including plastic surgeons. In patients with need of more extensive cover of defects, the transplant of muscular or fasciocutaneous free flaps has provided good results in the few centres that have applied this technique. This procedure can be combined with a revascularization in the same session or at a later stage. A majority of the described techniques can be implemented in most vascular centres and they should be considered in complicated cases when standard methods of revascularization and reconstruction do not suffice.
