dc.description.abstractObjective. To assess the influence of diabetes mellitus on early morbidity and mortality following open vascular surgical interventions. Methods. Clinical data on patients subjected to open vascular surgical procedures over a 5 year period at the Durban Metropolitan Vascular Service was culled from a prospectively maintained computerized database. They were divided according to the type of surgical procedure performed. These were open abdominal aortic surgery, peripheral bypass surgery, lower extremity major amputation and carotid endarterectomy. They were further subdivided into 2 groups, diabetic and non-diabetic. Results. 1104 charts were analysed. There were no significant differences in demographics and risk factors between the two groups. 273 patients had open abdominal aortic surgery. 217 (79%) were non-diabetic. diabetic patients had significantly higher incidence of myocardial infarction (p=0.00001) (6 of 6 patients), graft sepsis (p=0.000001) (7 of 7 patients) and mortality rate (p=0.0335) (5 of 10 patients). 337 patients had peripheral bypass procedures. 204 (60%) of these were non-diabetic. There was a high prevalence of smokers among non-diabetics and of hypertension among diabetics. Diabetic patients had a preponderance of graft infection (p=0.0015) (15 of 20 patients) and cardiovascular complications (p=0.0072) (7 of 8 patients). 230 patients had lower extremity major amputations, 81 (35%) were diabetic and 149 (65%) non-diabetic. Myocardial infarction and death (6 of 8 patients each) were significantly higher among diabetics (p =0.04). 264 patients had carotid endarterectomy, 170 (64%) being non-diabetic. The surgical outcome was similar between the two groups. Conclusions. This is retrospective study and as such it has some its limitations. Not all patients might have been included in the study and some of the information might have been lost. The numbers in this study are large and these limitations would appear not to have influenced the outcome of this study. This study has shown that diabetes mellitus had diverse influence on the early outcome following different vascular surgical procedures. Diabetes mellitus significantly increased the incidence of graft sepsis among those who had aorto-bifemoral bypass and peripheral bypass procedures. The incidence of peri-operative cardiovascular morbidity was significantly increased among diabetics who had peripheral bypass procedures, open abdominal aortic surgery and lower extremity major amputations. Diabetes mellitus had no influence on the surgical outcome following carotid endarterectomy.en
