COMPARATIVE-ANALYSIS OF PATENCY, LIMB SALVAGE AND SURVIVAL IN DIABETIC AND NONDIABETIC PATIENTS UNDERGOING INFRAINGUINAL BYPASS-SURGERY

In 92 diabetic and 175 non-diabetic patients undergoing 336 femoropopl iteal or femorodistal bypass procedures, 1- and 3-year cumulative life -table patency, limb salvage, and survival rates were comparatively an alysed. The peroperative mortality rate was significantly higher in di abetic patients (5 % compared to 1.4 %, p<0.001). The cumulative graft patency rates were 61 % at 12 months and 46 % at 36 months in diabeti c patients compared to 64 and 52 % in non-diabetic patients. Significa ntly better patency rates were observed in limbs with good runoff comp ared to limbs with poor runoff in both groups. The limb salvage rates at 3 years were 70 % in diabetic patients and 62 % in non-diabetic pat ients. The survival rate at 3 years was significantly lower in diabeti c patients, 62 % compared to 86 % in non-diabetic patients. Diabetic p atients with poor runoff demonstrated a significantly lower survival r ate after 36 months compared to diabetic patients with good runoff (48 % and 74 %, respectively). The results of this study demonstrate that the early and intermediate patency and limb salvage rates are similar in diabetic and non-diabetic patients. On the other hand the survival rate in diabetic patients,
