DF 与ASO 患者下肢动脉CT 血管造影病变分析

Analysis of CTA lesions of lower extremity arteries in patients with diabetic foot and non-diabetic atherosclerosis occlusion disorder

摘要:

目的 探讨糖尿病足（DF）与非糖尿病性动脉硬化闭塞症（ASO）患者的下肢动脉CT 血管造 影（CTA）病变分布临床特点。方法 选取2011 年8 月-2013 年8 月于兰州军区总医院的112 例DF 患者和 89 例ASO 患者，分别作为DF 组和ASO 组，采用CTA 进行检查，比较两组患者CTA 病变情况。结果 DF 组患肢209 条，621 处病变；ASO 组患者189 条，321 处病变。两组患者单节段、双节段及多节段动脉累及率 比较无差异（P >0.05）；两组患者的单节段、双节段病变膝下动脉累及率比较有差异（P <0.05）；两组患者 患肢的髂、股及腘动脉累及率比较有差异（P <0.05）；两组患者胫前、胫后、腓及足底动脉累及率及其病变 膝下动脉累计率比较有差异（P <0.05）。结论 DF 下肢动脉病变多分布于膝下的胫前、后动脉、腓动脉及足 背动脉环等较小动脉，而ASO 多分布于髂动脉、股动脉及腘动脉等下肢相对较大动脉。

Abstract:

Objective To study the lesion distribution and clinical characteristics in lower limb arterial CT angiography (CTA) of the patients with diabetic foot (DF) and non-diabetic atherosclerosis occlusion disorder (ASO). Methods A total of 112 cases of DF patients (DF group) and 89 cases of ASO (ASO group) treated in the General Hospital of Lanzhou Military Region from August 2011 to August 2013 were selected. CTA was used to examine the lesions of the 2 groups of patients. Results In the DF group 209 limbs were involved with 621 lesions, while in the ASO group 189 limbs were involved with 321 lesions. There was no significant difference in the incidence of single, double and multiple segmental arterial involvement between the two groups (P > 0.05). The involvement rate of single and double segmental lesions had obvious difference between the two groups (P < 0.05). The rate of limb iliac, femoral and popliteal artery involvement had obvious difference betweenthe two groups (P < 0.05). The rates of anterior tibial artery, posterior tibial artery, fibular artery and plantar artery ring involvement and the inferior genu artery involvement rate in the patients with iliac, femoral and popliteal lesions were obviously different between the two groups (P < 0.05). Conclusions In the patients with DF, the lesions of lower limb arteries are mainly located in small arteries such as anterior and posterior tibial arteries, fibular artery and plantar artery ring; while ASO chiefly involves relatively large arteries of the lower extremities, such as iliac artery, popliteal artery and femoral artery.
