摘要
目的探讨糖尿病足病患者下肢动脉造影特点及与踝肱指数的相关性。方法纳入52例糖尿病足患者,同时进行双下肢踝肱指数(ABI)及动脉造影(DSA)检查,分析股浅、腘胫前、胫后、腓及足背动脉各段病变特点,并按动脉狭窄程度进行评分,与ABI进行相关性比较。结果共91条肢体行ABI测量,其平均值为0.73±0.43(0.15~1.97);其中18条(19.8%)肢体0.9<ABI≤1.3;63条(69.2%)ABI≤0.9;10条(11.0%)ABI>1.3;其相应的DSA结果显示动脉狭窄≤50%、>50%且<100%与完全闭塞在各段血管中所占比例分别为:股动脉49.5%、22%、28.5%,腘动脉79.1%、14.3%、6.6%,胫前动脉25.3%、8.8%、65.9%,胫后动脉29.7%、14.3%、56.0%,腓动脉25.3%、20.9%、53.8%,足背动脉54.9%、14.3%、30.8%。46条肢体(50.5%)存在至少3支动脉闭塞。血管评分平均分为8.5±4.3(0~18);ABI与血管积分呈负相关(r=-0.588,P<0.05)。结论糖尿病足病患者下肢动脉病变广泛,从股动脉至足背动脉均可受累,呈多节段性改变;以胫前动脉、胫后动脉及腓动脉严重狭窄或闭塞为主。
Objective To evaluate the Digital Subtract Arteriography(DSA) characteristics of lower limb arterial diseases in patients with diabetic feet and to explore the correlation between DSA and Ankle-brachial index(ABI).Methods Fifty-two patients with diabetic feet were recruited in this study.ABI and DSA of bilateral lower extremities were examined to assess the severity of vasculopathy.The relationship between ABI and DSA was analyzed.Results ABI values for 91 lower extremities were obtained,with a mean of 0.73±0.43(0.15-1.97),among which 19.8% ranged from 0.9 to 1.3,69.2% were less than 0.9,and 11% were more than 1.3.Based on the integrated angiographic images,the arteries with ≤50% degree of stenosis,50%-99% degree of stenosis and occlusion comprised 49.5%,22%,and 28.5% for femoral artery;79.1%,14.3%,and 6.6% for popliteal artery;25.3%,8.8%,and 65.9% for anterior tibial artery;29.7%,14.3%,and 56% for posterior tibial artery;25.3%,20.9%,and 53.8% for peroneal artery;and 54.9%,14.3%,and 30.8% for dorsal pedis artery.Forty(50.5%) limbs had three or more above-mentioned arteries occluded simultaneously.The average vascular score was 8.5±4.3 with a range between 0 and 18.The spearman correlation analysis showed that ABI inversely correlated with artery stenosis score(r=-0.588,P<0.05).Conclusion Arterial diseases of lower extremities in patients with diabetic feet are wide-spread,ranging from femoral artery to the dorsal pedis artery.Multiple segments of arteries are involved.Severe stenosis and occlusion are more common in anterior and posterial tibial arteries,and peroneal artery.
