64排CT在糖尿病下肢动脉硬化闭塞症中的应用

Diagnostic Value of 64 Slice CT Scan in Diabetic Lower Limb Arteriosclerosis Occlusion

目的:探讨64排CT在糖尿病下肢动脉硬化闭塞症中的应用。方法:选择我院收治的糖尿病下肢动脉硬化闭塞症患者86例,先进行64排CT扫描(CTA),后再进行数字减影检查(DSA),比较两种方法诊断的准确性和血管病变检查情况。结果:CTA对下肢血管病变准确范围、部位等显示清晰。其检测的敏感性显著高于DSA,P<0.05。且前者特异性、准确性均优于后者。DSA发现狭窄或闭塞血管76段,CTA发现狭窄或闭塞血管84段,其中包括31例轻度狭窄,25例中度狭窄,16例重度狭窄,12例完全闭塞(有侧枝循环血管形成)。结论:CTA对糖尿病下肢动脉硬化闭塞症可有效地检测诊断,与DSA相比较,能提高检测准确率,值得临床推广应用。

Objective:To explore the value of 64 Slice CT scan in diabetic lower limb arteriosclerosis occlusion.Methods:86 patients with diabetic lower limb arteriosclerosis occlusive disease in our hospital were selected.Then 64 slice CT angiography and digital subtraction angiography were performed in succession.The diagnostic accuracy and vascular condition were compared between the CTA group and the DSA group.Results:64 slice CT angiography showed a clear range and location of lower extremity vascular disease.The sensitivity of detection was significantly higher than that of DSA,and the former is more accurate and specific than the latter.76 cases of stenosis or occluded vessels were founded in DSA.And 84 cases of stenosis or occluded vessels were founded in CTA,including 31 cases of mild stenosis,25 cases of moderate stenosis,16 cases of severe stenosis,12 cases of complete occlusion(with collateral vessel formation).Conclusion:CTA can effectively detect and diagnose diabetic lower limb arteriosclerosis occlusive disease,compared with DSA,it can effectively improve the detection accuracy,thus it is worthy of clinical application.
