Screening for significant carotid artery disease among a cohort of 1,000 Egyptian patients.

The objective of this study was to determine the prevalence of significant carotid artery disease (SCAD) in a cohort of Egyptian patients to compare it with matched groups of patients in published data of Western populations. One thousand consecutive patients referred for color flow duplex scanning of the carotid arteries were included. SCAD was defined as carotid stenosis > or = 50% or occlusion.

Duplex detected ankle peak systolic velocity: a new parameter for the assessment of degree of peripheralischemia.

Aim: The objective of this study was to assess the sensitivity and specificity of a newly developed parameter: the ankle peak systolic velocity (APSV) to provide an objective assessment of the degree of peripheral ischemia.

Methods: In phase 1 of the study: data was prospectively collected for 21 ischemic limbs and 5 healthy volunteers. APSV was calculated as the mean value of the distal anterior and posterior tibial arteries peak systolic velocities (PSV).
