SummaryPeripheral arterial disease (PAD) is an important global health-care problem associated with considerable morbidity and mortality. This disease is an important manifestation of atherosclerosis and the pathophysiological processes involved in its development, progression and complications are atherothrombosis and thromboembolism. Over 150 years ago, Virchow described a triad of abnormalities (abnormal blood flow, abnormal vessel wall and abnormal blood constituents) associated with thrombus formation (thrombogenesis). An improvement in biochemical techniques has allowed quantification of various components of Virchow’s triad, and as a consequence, there has been increasing interest in the measurement of such biomarkers in understanding the development and progression of PAD, as well as its symptomatic complications. This review discusses quantifiable components of Virchow’s triad that have been associated with PAD and their clinical utility as risk factors for PAD.

The purpose of this study is to analyze how accurate duplex ultrasonography using color Doppler and computed tomography (CT) angiography are in detection of peripheral arterial disease (PAD) in comparison with the Gold Standard of digital subtraction angiography (DSA). This is a single-center prospective, analytical study done on patients with symptoms of PAD referred to the Department of Radiodiagnosis of Medical Trust Hospital (n = 53). All patients were imaged with color Doppler, CT angiography, and DSA. The peak systolic velocity (PSV) ratio was calculated by Doppler ultrasound, and the percentage stenosis for the same vascular segments was calculated using CT angiography and DSA. To test the statistical significance between the results, chi-square test was used. A P value <.05 indicates statistical significance. The PSV ratio for each grade—normal (<1.5), mild (1.5-2.8), moderate (2.9-4.9), and severe (≥5)—and the percentage of stenosis for each grade observed on CT angiography—normal (<20% stenosis), mild (20%-49% stenosis), moderate (50%-74% stenosis), severe (75%-99% stenosis), and total occlusion (100% stenosis)—were found to be highly sensitive and specific with good positive predictive value, negative predictive value, and accuracy level when compared with DSA with narrow confidence intervals for each range. The P value was <.001 for both color Doppler and CT angiography. Computed tomography angiography can be an effective tool as an alternative to DSA for gradation of stenosis if the artifacts resulting from vascular calcification can be avoided. Duplex ultrasonography can be utilized for gradation of stenosis by using the value of PSV ratio and spectral pattern together. However, it can only act as an adjunct to CT angiography because it is incapable of imaging the full length of the arterial segments in 1 frame.
