The results of this investigation indicate overall phenomenological similarity in AAA flow patterns across the models. Specifically, wall shear stress and oscillatory shear index in the bulge portion of the models are of interest. The influence of aorto- iliac bifurcation and iliac stenosis on AAA flow dynamics is then explored through a comparison of the nature of flow patterns, vorticity evolution, vortex core trajectory and hemodynamic factors against the reference configuration. Flow characteristics are first established in the model resembling a symmetric AAA with a straight outlet tube. Physiological flows in rigid diseased arterial flow phantoms emulating an abdominal aortic aneurysm (AAA) under rest conditions with aorto- iliac bifurcation and iliac stenosis are examined in vitro through 2D PIV measurements. The needle position from the posterior superior iliac spine and its angle ofÂ .Įffect of aorto- iliac bifurcation and iliac stenosis on flow dynamics in an abdominal aortic aneurysm School of Medical Sciences, University of Science and Technology between 2006 and. Limitations in the availability of such image guided techniques in health. Sacroiliac joint injection using the posterior superior iliac spines as. We considered that the pelvic mensuration should be done in large number of normal and patients and further study in this fields should be carried out Iliac index seems to be more reliable than either of acetabular angle and iliac angle in the detection of abnormal pelvic contuor in patients with mongolism. Significant increase in acetabular angle is observed in patients with congenital dislocation of hip and significant decrease in iliac index in patients with mongolism is observed.

The values of acetabular angle, iliac angle and lilac index are significantly lower than those of American children. Considering that there is no available standard values of Korean children, we measured acetabular angles, iliac angles and iliac indices in 150 normal Korean children, 10 cases of congenital dislocation of hip and 2 cases of mongolism. International Nuclear Information System (INIS)Ībnormal pelvic configuration with resultant abnormal value of acetabular angle, iliac angle and iliac index is well known in some congenital and hereditary diseases and its measurement is valuable in establishing diagnosis in these diseases.
