下肢动脉疾病的CDUS、CTA与DSA对比研究
Contrast Study of CDUS, CTA and DSA in Lower Extremity Artery Disease Diagnosis
摘要: 目的:探讨彩色多普勒超声(CDUS)CT血管造影(CTA)及数字减影血管造影(DSA)在下肢动脉疾病诊断中的应用价值。方法:100例下肢动脉疾病患者分别采用CDUSCTADSA检查。结果:血栓闭塞性脉管炎(TAO)及周围动脉损伤CDUSCTADSA的诊断符合率均为100%;而下肢动脉硬化闭塞症(ASO)的相应检查符合率分别为95.2%97.6%100%;动脉瘤和假性动脉瘤为100%100%91.6%;急性肢体动脉栓塞(AAEE) 87.5%100%100%;动静脉瘘(AVF)83.3%.83.3%100%结论:CDUS无创伤,能够全面观察血管管腔,管壁结构及血流状况;CTA对管壁周围及腔内直观显像能直接表明管壁受侵及管腔改变;DSA能精确诊断血管病变程度、部位、侧枝循环及小动脉。三者密切结合不仅可准确诊断下肢动脉疾病,还可对指导临床治疗有重要价值。 Objective: To explore the application value of CDUS, CTA and DSA in lower extremity artery disease diagnosis. Methods: 100 patients with lower extremities arteriopathy were examined under CDUS, CTA and DSA. Results The positive rates of diagnosis for thromboangitis obliterans (TAO), arteriosclerosis obliterans (ASO), aneurysm and pseudoaneurysm, acute artery embolism of the extremity (AAEE) and arteriovenous fistula (AVF) under CDUS, CTA and DSA examination respectively were: 100%, 100%, 100%; 95.2%, 97.6%, 100%; 100%, 100%, 91.6%; 87.5%, 100%, 100%; 83.3%, 83.3%, 100%. Conclusion: CDUS is non-invasive and it can give a comprehensive observation of the artery lumens, vessel walls and the blood stream; CTA can display changes of peripheral vessel walls and lumens clearly; DSA can show accurate degrees of vessel diseases, location, collateral circulation and arteriola. Lower extremity arteriopathy can be diagnosed accurately under the combination of these methods which are of great importance to guide the clinical treatment.
