The prevalence of carotid and iliac-femoral artery disease as detected by Duplex scanning was assessed among 239 subjects living in retirement houses in Seattle. The population average age was 80.8 and the standard deviation was 5.5. The method used to assess the carotid and iliac-femoral artery disease was Duplex scanning, a noninvasive method that combines a B-mode ultrasound imager with a pulsed doppler flow detector to assess flow velocities at specific locations in the visualized artery. The diagnostic criteria for the carotid and femoral disease were based on the interpretation of spectral analysis and B-mode imaging. We found 40 people (16.74%) without either carotid or iliac-fem oral arteries diseases, 40 people (16.74%) affected by carotid diseases, 40 people (16.74%) affected by iliac-femoral disease and 119 people )49.78%) with disease in both sites. Direct correlation was demonstrated between severity of arterial disease as assessed by Duplex scanning and age (r = 0.306; p < 0.001) or systolic pressure (r = 0.201; p < 0.01). A high percentage of patients with arterial disease was demonstrated in this age group. Very seldom people without any detectable abnormality were found. Often the disease involved both carotid and leg arteries.

Abstract

The prevalence of carotid and iliac-femoral artery disease as detected by Duplex scanning was assessed among 239 subjects living in retirement houses in Seattle. The population average age was 80.8 and the standard deviation was 5.5. The method used to assess the carotid and iliac-femoral artery disease was Duplex scanning, a noninvasive method that combines a B-mode ultrasound imager with a pulsed doppler flow detector to assess flow velocities at specific locations in the visualized artery. The diagnostic criteria for the carotid and femoral disease were based on the interpretation of spectral analysis and B-mode imaging. We found 40 people (16.74%) without either carotid or iliac-fem oral arteries diseases, 40 people (16.74%) affected by carotid diseases, 40 people (16.74%) affected by iliac-femoral disease and 119 people )49.78%) with disease in both sites. Direct correlation was demonstrated between severity of arterial disease as assessed by Duplex scanning and age (r = 0.306; p < 0.001) or systolic pressure (r = 0.201; p < 0.01). A high percentage of patients with arterial disease was demonstrated in this age group. Very seldom people without any detectable abnormality were found. Often the disease involved both carotid and leg arteries.
