| Summary: | Background: Peripheral 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. Aim: We 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 methods: A 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.
Results: According 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. Conclusion: Despite 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. |
