Microsurgery in the diabetic foot.
The treatment of serious tissue defects on the diabetic foot is complicated and tedious because of a combination of pathogenetic mechanisms that influence healing. Diabetic neuropathies (sensory, motor, vegetative), ischaemia and microangiopathies contribute in varying degrees to the adverse healing. The submitted three-year prospective study was focused on an analysis of the pathogenetic factors with the objective of defining the indications for one of three types of microsurgical transfer: 1. a free flap sutured directly to the vessels at the site of the defect (in predominantly neuropathic defects); 2. a free flap sutured to a politeopedal bypass (in predominantly ischaemic defects); 3. a "nourishing" flap sutured by means of a long venous graft to vessels of the medial and upper leg (in patients in whom an inadequate outflow tract does not make revascularisation possible). In the first year of the investigation, thirteen patients were operated on by means of a free muscle flap incl. three "nourishing" and ten sutured at the site of the defect. Twelve flaps were flaped healed; one patient died from myocardial infarction on the second day after surgery.
