摘 要: | 目的探究外周血管超声联合CT血管造影(CTA)应用于下肢动脉硬化闭塞症(LEASO)的临床效果。方法对26例LEASO患者(315段病变血管)临床资料进行回顾性分析,以数字血管减影造影(DSA)检查结果为"金标准",比较外周血管超声、CTA及二者联合评估病变血管狭窄程度的符合率差异。结果 315段LEASO病变血管中,轻度狭窄89段,中度狭窄96段,重度狭窄76段,闭塞54段。三种方案诊断符合率比较,外周血管超声联合CTA85.40%(269/315)]>CTA79.05%(249/315)]>外周血管超声71.43%(225/315)],差异均有统计学意义(χ^2=18.335,P<0.001)。结论外周血管超声联合CTA应用于LEASO能明显提高病变血管狭窄程度诊断的符合率,可准确为临床诊治策略及预后评估提供参考。

Abstract: | Objective To explore the clinical effects of peripheral vascular ultrasound combined with CT angiography(CTA) in the diagnosis of lower extremity arteriosclerosis obliterans(LEASO). Methods The clinical data of 26 patients with LEASO(315 segments of lesion vessels) were retrospectively analyzed. The examination results of digital subtraction angiography(DSA) were used as the gold standards, and the coincidence rates of peripheral vascular ultrasound, CTA and the combination of the two were compared in the evaluation of stenosis degree of lesion vessels. Results Among the 315 segments of LEASO lesion vessels, there were 89 segments of mild stenosis, 96 segments of moderate stenosis, 76 segments of severe stenosis and 54 segments of occlusion. The diagnostic coincidence rates of the three regimens showed peripheral vascular ultrasound combined with CTA 85.40%(269/315)]>CTA 79.05%(249/315)]>peripheral vascular ultrasound 71.43%(225/315)](χ^2=18.335, P<0.001). Conclusion Peripheral vascular ultrasound combined with CTA in LEASO can significantly improve the coincidence rate of diagnosis of stenosis degree of lesion vessels, and it can provide a reference for clinical diagnosis and treatment strategy and prognosis evaluation. |
