| 摘 要： | 目的:研究糖尿病下肢动脉病变64层螺旋CT血管成像（CTA）特征。方法:回顾性分析80例临床诊断为糖尿病，并行64层螺旋CTA检查的患者资料。下肢动脉分为4段（髂动脉段、股动脉段、腘动脉段和小腿动脉段）。统计下肢动脉病变部位、数目、性质、长度（<5 cm，5~10 cm和>10 cm）并分析其特点。结果:根据4分段法，80例患者中病变动脉148条，多节段病变55（37.16%）条，其中受累股动脉104（70.27%）条，受累的小腿动脉134（90.54%）条。总病变325处，其中闭塞性疾病179（55.08%）处，狭窄性病变约146（44.92%）处。>10 cm闭塞病变主要发生在小腿动脉66处，占小腿动脉病变的49.25%，以胫前动脉和胫后动脉为主。结论:糖尿病下肢动脉病变CTA表现主要以多节段硬化闭塞为主，多累及股动脉和小腿动脉。无创性CTA可用于下肢动脉病变的常规评估。

| Abstract: | Objective: To study the characteristics of 64 slice spiral CT angiography (CTA) in diabetic lower extremity arterial disease (LEAD). Methods: Analyze the clinical data of 80 diabetic cases that performed 64 slice spiral CTA examination retrospectively. The arteries of lower extremity were divided into the following four segments:Iliac, femoral, popliteal and crural artery. Count on the lower extremity arterial lesions, number, feature and length (<5 cm, 5-10 cm, >10 cm), and analyze the characteristic of LEAD. Results: Of 148 diabetic lower limbs in the 80 cases, multiple segmental lesions were seen in 55(37.16%), femoral arterial lesions in 104, and crural arterial lesions in 134. Based on segmental angiographic classification, a total of 325 vascular lesions were detected, including stricture lesions (44.92%) and occlusive lesions (55.08%). Of the 134 crural lesions, 70.90% were occlusions, and most of which were longer than 10 cm and located in anterior and posterior tibial arteries, while only a few peroneal arteries were involved (P<0.05). Conclusion: The main feature of diabetic LEAD is multi-level atherosclerotic occlusion, the femoral and the crural arteries are most likely to be involved. Non-invasive MSCTA can be used for routine evaluation of LEAD. |
