A Comparison of Transcranial Doppler (TCD) Findings in Diabetic Patients with a History of Less and More than 5 Years Referred to the Diabetes Clinic of Imam Khomeini Hospital in Ardabil

Diabetes mellitus is the sixth leading cause of death in individuals older than 25 years, and accounts for %18 of all deaths. The aim of this study was to investigate the TCD findings in diabetic patients with a history of less and more than 5 years.
In this descriptive, analytic study, all diabetic patients were divided into two groups based on the duration of diabetes, less and more than 5 years after diagnosis. TCD was performed on the patients, and maximum velocity and mean pulsatility index and resistivity index in the right and left Middle Cerebral Arteries (MCAs) and basilar artery were measured. The checklist was completed for all patients, and all data were analyzed by SPSS (v16) statistical software.
Sixty four percent of the patients with duration less than 5 years (average age of 55.16 years) and 36 percent of those with duration more than 5 years (average age of 59.37 years) were men. There was no statistically significant difference between disease duration and Body Mass Index (BMI), but with an increase in duration of disease, HbA1C of patients was increased. There was no significant difference between the velocity of right, left and basilar arteries and diabetes duration. Also, there was a significant difference between diabetes duration and pulse index of right MCA and basilar. There was no significant difference between age, BMI and HbA1C and pulse and resistivity indexes among patients.
In this study abnormal pulse and resistance indexes in patients with duration more than 5 years was more than patients with less than 5, this may indicate the effect of diabetes duration on the vascular wall.
