[Surgical treatment of ischemia in the diabetic foot syndrome]

The authors present their results of the treatment of diabetic foot critical ischemia by means of surgical revascularisation together with minor amputation or debridement. They discuss the causes of higher amputations and re-amputations in revascularised ischemic diabetic lower limbs and presents patency rates in different types of peripheral arterial bypasses. The authors evaluated 81 diabetic feet with chronic critical ischemia, where they performed 50 arterial bypass procedures in the 50 limbs (13 femoropopliteal, 13 femorodistal, 19 pedal bypasses and 5 aorto/ilicofemoral or extraanatomical bypasses). 41 minor amputations or debridements (82%), 6 minor re-amputations (12%) was performed in the group of 50 revascularised limbs. The primary patency rates, secondary patency rates and limb salvage was achieved 92%, 92% and 92% in femoropopliteal bypass, 91%, 91% and 92% in femorodistal bypass, 78%, 83% and 84% in pedal bypass, respectively. The average follow-up time was 11.4 months. 6 minor re-amputations (12%) and 5 high amputations was necessary to perform in the group of 50 revascularised lower limbs. The main cause of re-amputation and high amputation was continuing ischemia. 30 day mortality rate was 0%, 30 day morbidity rate was 8% (myocardial infarction and pulmonary embolism).
