Introduction. Surgical treatment is a "golden standard" in treating internal carotid arteries stenosis. Performing a surgical procedure - the internal carotid artery thrombendarterectomy - requires a careful analysis of the risk of perioperative complications. Aim. The aim of this work is to consider age and sex of patients as risk factors of postoperative neurological complications. This may help to determine a sub-population of patients with a potentially higher risk of complications. Materials and methods. 142 patients operated for internal carotid arteries stenosis at the Department of General and Vascular Surgery of the Provincial Specialist Hospital in Olsztyn between 2000 and 2004 participated in the prospective study. Two groups of patients were analysed: group I, diagnosed with neurological symptoms before the surgery, consisted of 102 patients (7 1.8%), control group II, with no neurological symptoms before the surgery, consisted of 40 patients (28.2%). 41 women (28.9%) and 101 (71.1%) men underwent surgical treatment. Age of the patients oscillated between 42-80 years (61.6 on average) in research group I and 45-81 years (63.3 on average) in control group II. The chi2 test, logistic analysis and log-linear analysis were employed for the statistical analysis. Results and discussion. In the control group II, transient brain ischaemia was revealed in 2 women and 1 man over 65 years old. Ischaemic cerebral stroke occurred in 2 men (1 in each age group). In the study group I, transient brain ischaemia was observed in 4 men and 1 woman below 65 years of age. Ischaemic cerebral stroke occurred in 2 women and 2 men below 65 and in 2 men over 65 years of age. Statistical analysis did not reveal any significant correlation between particular groups. Conclusions. No statistically significant correlation between the frequency of post- operative neurological complications and age and sex of the operated patients was observed. [ABSTRACT FROM AUTHOR]
