Diabetic foot or the syndrome of diabetic foot (SDF) is the problem due to a high frequency of ablations of the lower extremities followed with a significant social, psychological and economic consequences. The research objective is to estimate diagnostic opportunities of ultrasound doppler scanning (UDS) of arteries of lower extremities in the patients with diabetes mellitus (DM) in development of purulent-necrotic complications. The main group consisted of 141 patients with DM who were treated at purulent-septic center «City Hospital N 3» in Zaporizhzhya, during 2017-2018. Control group – 274 patients who were receiving treatment during 2009-2013. The average duration of DM was 12,8±2,9 years. Average age of patients was 56,3±5,3 years. 63 (44,7%) were men, women – 78 (53,3%). The groups were representative by key indicators and the accompanying pathology. During hospitalization patients had signs of purulent-necrotic lesion of the lower extremity. The complex of diagnostic actions included obligatory diagnostics of a vascular bed of the lower extremities by means of UDS. By comparison with retrospective data it was defined that the number of DM patients with vascular problems in development of purulent-necrotic complications has increased. If earlier the percentage of distribution to etiological forms made up: neuropathic - 36,9%, ischemic - 23,4%, mixed – 39,7%, currently, mixed form (p

Aim. To develop a less traumatic method of surgical treatment of the lower extremities (VVLE). Methods and results. Known method of radical treatment of varicose veins of the VVLE is the single-step execution of the phlebectomy of the large and small v. subcutaneous trunk, collaterals with subfascial ligation of perforating veins. But the method is highly traumatic. For the purpose to develop a less traumatic method of surgical treatment of the VVLE, 97 patients VVLE C2-C6 were examined with CEAP. Radical way of surgical treatment of the VVLE was developed. Components of the proposed operation are: crossectomy, short stripping of the trunk of v. subcutaneous major with removal of Boyd perforants, mini-phlebectomia by Muller. Conclusion. It was established that the method has a smaller injuries and operative time, allows to save unaltered subcutaneous veins, have better cosmetic effect that testifies the advisability of the proposed method of treatment.
