摘　　要：目的:探究多层螺旋CT直接静脉造影检查技术对下肢静脉血栓性病变的诊断效果及对预后的影响。方法:选取2020年3月~2022年3月本院接诊的60例疑似下肢静脉血栓性病变患者,采用64层螺旋CT直接静脉造影检查技术与传统超声检查,分析多层螺旋CT直接静脉造影诊断检出率,以病理检测结果为金标准,对比两种检测方式下准确率、敏感度及特异度,随访评估预后效果。结果:多层螺旋CT直接静脉造影对下肢静脉血栓性病变的检出率高于传统超声,检测灵敏度、特异度及准确度高于常规超声(P<0.05)。随访观察发现采用多层螺旋CT直接静脉造影指导临床治疗方案,患者不良反应发生率低,预后良好。结论:多层螺旋CT直接静脉造影检查技术对下肢静脉血栓性病变的诊断检出率高、诊断灵敏度、特异度及准确度均较高,多层螺旋CT直接静脉造影可通过清晰图像准确对下肢静脉血栓性病变血栓情况进行有效分析,利于后期治疗方案的确定。Objective:Exploring the diagnostic efficacy of multi-slice spiral CT direct venography(DSCT direct venography)in lower limb venous thrombotic lesions and its impact on prognosis.Methods:60 suspected patients with lower limb venous thrombotic lesions who were admitted to our hospital from March 2020 to March 2022 were selected.The 64 slice spiral CT direct venous imaging technology and traditional ultrasound examination were used to analyze the diagnostic detection rate of DSCT direct venous imaging.The pathological test results were used as the gold standard to compare the accuracy,sensitivity,and specificity of the two detection methods,and the prognosis was evaluated through follow-up.Results:The detection rate of lower limb venous thrombotic lesions using DSCT direct venography is higher than that of traditional ultrasound,and the detection sensitivity,specificity,and accuracy are higher than those of conventional ultrasound(P<0.05).Follow up observations revealed that using DSCT direct venography to guide clinical treatment plans resulted in a low incidence of adverse reactions and a good prognosis for patients.Conclusion:Multi-slice spiral CT direct venous imaging technology has a high diagnostic detection rate,diagnostic sensitivity,specificity,and accuracy for lower limb venous thrombotic lesions.DSCT direct venous imaging can accurately analyze the thrombus situation of lower limb venous thrombotic lesions through clear images,which is conducive to the determination of later treatment plans.
