Popis: Background and purpose:to determine if diabetes mellitus is a risk factor for outcome after carotid endarterectomy (CEA).Methods:the outcome and complications of all vascular procedures performed in Sweden are registered prospectively in the Swedish Vascular Registry (Swedvasc) and form the basis of this report. During the 10-year period 1987–96 2622 CEAs were analysed for notified complications.Results:of the 2622 CEAs, 341 (13%) were performed on diabetics and 2281 (87%) on non-diabetics. Patients with diabetes presented at a younger age (67.1±8.3 years vs. 68.2±8.3 years p =0.028), were more likely to have a history of hypertension (61.9% vs. 50% p =0.001) and were less often smokers (34.9% vs. 43.2% p =0.001). Diabetics presented more often with minor stroke (41.3% vs. 30.8% p =0.002) and non-diabetics more often with amaurosis fugax (18.9% vs. 14.4% p =0.04). Diabetics had a higher 30-day mortality (3.2% vs. 1.4% p =0.02). The 30-day neurologic and cardiac morbidity did not differ. The 1-year mortality was 7.9% in diabetics and 4.4% in non-diabetics (p =0.008). Non-diabetics operated on in 1992–96 compared to those operated on in 1987–91 had a significantly lower combined permanent stroke and death rate (3.7% vs. 5.7% p =0.05), a difference not found in diabetics (6.3% for 1987–92 and 6.8% for 1992–96Conclusions:diabetics had both a higher 30-day and 1-year mortality after CEA compared to non-diabetics, mainly because of cardiac complications. However, postoperative neurologic morbidity did not differ.
