characterization of the aorta and lower limbs arteries in patient with chorionic diseases using Computed Tomography

Abstract

The objective of this clinical study was to establish normal values of femoral artery dimension and compare between the diameter for abdominal aorta at its bifurcation to left and right femoral artery using Multi Detector Computed Tomography, and to find the effect of gender on the size of the femoral artery. Abdominal part (aorta at bifurcation) and femoral artery was measured at three sites in the femur of 100 healthy subjects using RadiAnt DICOM viewer system. The study showed that the dimension of abdominal aorta and the right and left femoral artery its slightly bigger in male than female in average it was 16.74 to 16.17 and for right and left side; femoral artery bigger in male than female in average 8.25 to 7.39, all these differences were inconclusive using t-test except the medium (0.047) and upper right femoral artery (0.003). the results also showed that there is strong correlation between the right and left femoral artery; concerning the lower, medium and upper femoral artery 0.78, 0.88 and 0.66 respectively, and in paired t-test there is no significant difference between medium, upper right and left femoral artery at p =0.05 while lower part of the femoral artery concerning the right and left side showed significant differences p = 0.02. The important impression in this study is that the diameter of the femoral part (lower, medium and upper) can be estima ted from the size of the aorta at bifurcation as normal dynamic, sine the size at bifurcation was normal. And when compare thediabetic patients and hypertensive patients with normal as control group. The diameter measurement of abdominal aortic at its bifurcation to right and left femur artery and the study sample diabetic patients and hypertensive and which is bigger than that of hypertensive patients (7.41 mm) and diabetic (5.91 mm) patients, for abdominal aorta bifurcation of hypertensive patients the diameter was (17.18 mm) which is bigger than the normal (16.47 mm) and diabetic patient’s which is (14.89 mm). diameter of abdominal aorta and its bifurcation to left and right femoral artery show that the hypertensive patients showed bigger diameter than the normal and diabetic patients, and the dimension of left and right femoral artery the normal patients showed bigger diameter than hypertensive and diabetic patients.
