Results of autovenous femoro-distal bypass procedures in the type III peripheral obliterative arterial disease of the extremities in diabetic and nondiabetic patients

Abstract

Introduction. It has been established that infrainguinal occlusive disease, type III peripheral obliterative arterial disease (POAD), is more common in diabetics than in non-diabetics. It is presumeable that after surgical treatment of this arterial segment diabetics develop more complications and higher mortality rate than nondiabetics. The aim of this study was to analyze the results of reconstructive surgical treatment of diabetic and non-diabetic patients with type III PAOD. Material and Methods. In the period 1999-2003, 118 patients with Type III PAOD underwent surgery at the Vascular Surgery Clinic in Novi Sad. They were divided into two groups: group I included 51 nondiabetic patients, and group II 67 diabetic patients. Subgroups were formed based on the clinical status. Differences were established in IVa, (46 diabetics and 4 non-diabetics) and IVb stage (11 diabetic and 30 non-diabetic patients). Results. Statistical data analysis using X2 test showed a statistical difference in complications rates, number of salvaged limbs and finally, in the mortality rates between diabetic and non-diabetic patients. Conclusion. Diabetic patients presented with significantly more trophic skin lesions (IVa stage). The overall complication rate was significantly higher in diabetics, as well as the amputation rate. Finally, the mortality rate was also significantly higher in diabetics than in nondiabetic patients. .
