BackgroundPeripheral arterial disease is an atherosclerotic disease characterized by an increase in morbidity and mortality. For these reasons early diagnosis of peripheral arterial disease is important. Ankle-brachial systolic pressure index measurement is frequently used in screening studies. Evaluating waveforms of distal lower extremities with Doppler ultrasound can be used as a screening program and provides more accurate information on peripheral arterial disease.AimWe investigate the prevalence of peripheral arterial disease, compare the efficacy of Doppler ultrasound evaluation of distal lower extremity waveforms and ankle-brachial systolic pressure index measurement in screening programs, and discuss the importance of early diagnosis of asymptomatic cases.Material and methodsA total of 457 patients over the age of 65 (between 65 and 94, mean age: 71.4) including 270 males and 187 females were examined with Doppler ultrasound, had ankle-brachial systolic pressure index measurement taken and were screened for peripheral arterial disease. The correlation between Doppler ultrasound findings and ankle-brachial systolic pressure index was examined.ResultsAccording to the Doppler ultrasound findings, in the aortoiliac (r = 0.648) and femoropopliteal (r = 0.564) area, there is a medium level of correlation between severe stenosis and occlusions and a low ankle-brachial systolic pressure index value, and a low level of correlation between such abnormalities in the tibioperoneal region (r = 0.116) and a low ankle-brachial systolic pressure index value. Therefore, while the sensitivity of ankle-brachial systolic pressure index increases in proximal stenosis, it decreases in distal stenosis.ConclusionDespite the fact that ankle-brachial systolic pressure index is a diagnostic test commonly used in screening studies, evaluation of distal arteries by means of Doppler ultrasound provides more accurate information in terms of the identification of peripheral arterial disease.
