闭塞性动脉硬化症髂股动脉形态学表现与中医证型的相关性研究

目的:探讨闭塞性动脉硬化症(arteriosclerosis obliterans,ASO)髂股动脉各分支截面积与中医辨证分型的相关性。方法:收集ASO住院患者79例,其中血瘀型54例,湿热下注型25例,并选取非ASO患者30例作为对照,分别行MSCT髂股动脉造影检查,对每组的腹主动脉远端分叉、髂总动脉分叉及股总动脉分叉横截面积进行测量、计算,并统计比较。结果:髂股动脉多数分支的内面积和相对狭窄度ASO组明显小于对照组,右股总动脉内面积血瘀型小于湿热下注型,左股深动脉相对狭窄度湿热下注型明显小于血瘀型;腹主动脉远端分叉内面积扩张率ASO组明显小于对照组,右髂总动脉内面积扩张率湿热下注型小于血瘀型,双侧股总动脉内面积扩张率湿热下注型大于血瘀型及对照组。结论:ASO患者髂股动脉截面积与非ASO患者差异具有统计学意义,而ASO患者各中医证型之间亦存在一定差别。

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 approach characteristics of arteriosclerosis obliterans blood stasis syndrome and damp heat pouring down syndrome,and the difference between two syndrome. Methods： 79 cases of arteriosclerosis obliterans patients were selected as study object（54 cases in blood stasis syndrome group and 25 cases in damp heat pouring down syndrome） ,and 30 cases of the healthy voluntary persons were taken as the normal control group. Iliac femo ral artery of all the cases underwent imaging with multislice computed tomography angiography from the supraceliac abdominal aorta to the mid of femora/artery. In each patient,distal abdominal aorta and iliac femoral arterial bifurcations cross section area measurements were recorded,respectively. Then the data of each group were analyzed by statistics. Results：Iliac femoral artery inner areas and relative narrow grades were smaller in most of arteriosclerosis obliterans than control group ones. Compared with damp-heat pouring down syndrome group, the right common femoral artery inner area was smaller in blood stasis syndrome group while left profound femoral artery relative narrow grade was obviously greater. The inner area expansion rate of arterio sclerosis obliterans was smaller than that of control group in distal abdominal aorta bifurcation, while it was greater in right common femoral artery of damp-heat pouring down syndrome group than blood stasis syndrome group＇s,and greater than blood stasis syndrome group＇s or control group＇s in bilateral common femoral arteries. Conclusion：There are apparent differences in iliac femoral artery cross section area between arteriosclerosis obliterans and other patients or healthy persons,and arteriosclerosis obliterans damp-heat pouring down syndrome can be distinguished from blood stasis syndrome in certain respects.
