Research On The Relationship Between Iliac Femoral Artery Morphological Approach And Differentiation Of The Syndromes Of Arteriosclerotic Occlusive Diseases

Objective: To investigate the iliac femoral artery morphological approachcharacteristics of arteriosclerosis obliterans blood stasis syndrome and damp-heat pouringdown syndrome, and the difference between two syndrome. Methods:79cases ofarteriosclerosis obliterans patients were selected as study object(54cases in blood stasissyndrome group and25cases in damp-heat pouring down syndrome),and49cases of thehealthy voluntary persons were taken as the normal control group. Iliac femoral artery ofall the cases underwent imaging with multislice computed tomography angiography fromthe supraceliac abdominal aorta to the mid of femoral artery. Transverse sections wereacquired with a5mm nominal detector width and pitch of5.5following intravenousinjection of100ml of iodinated contrast medium (300mg iodine per milliliter).Images dataobtained were disposed with multiple planar reconstruction in work station. In each patient,distal abdominal aorta and iliac femoral arterial bifurcations cross section areameasurements were recorded, respectively. Then the data of each group were analyzed bystatistics. Results: Most of arteriosclerosis obliterans iliac femoral artery inner areas andrelative narrow grades are smaller than control group ones. Compared with blood stasissyndrome group, damp-heat pouring down syndrome group right common femoral arteryinner area is greater, while left profound femoral artery relative narrow grade is obviouslysmaller. Of all the iliac femoral arterys damp-heat pouring down syndrome group bilateralcommon femoral artery outer areas are greater than control group ones. The outer areaexpansion rate of arteriosclerosis obliterans is smaller than that of control group in distalabdominal aorta bifurcation, while it is smaller in right common femoral artery ofdamp-heat pouring down syndrome group than blood stasis syndrome group’s, and greaterthan blood stasis syndrome group’s or control group’s in bilateral common femoral arteries. Arteriosclerosis obliterans inner area asymmetrical factor is smaller than control group’s inright superficial femoral artery versus profound one, and blood stasis syndrome groupinner area asymmetrical factor is greater than control group’s in left superficial femoralartery versus profound one. Damp-heat pouring down syndrome group outer areaasymmetrical factor is greater than control group’s in right internal iliac artery versusexternal one, while arteriosclerosis obliterans outer area asymmetrical factor is greaterthan control group’s in left superficial femoral artery versus profound one. Conclusion：There is apparent differences in iliac femoral artery cross section area betweenarteriosclerosis obliterans and other patients or healthy persons, and arteriosclerosisobliterans damp-heat pouring down syndrome can be distinguished from blood stasissyndrome in certain respects. We can diagnose them primarily by multislice computedtomography angiography.
