摘要
目的:分析连续2点超声与D-二聚体(D-D)联合检测对下肢骨折术后疑似血栓的诊断价值。方法:选取2019年1—10月我院下肢骨折患者125例,均行择期手术,根据术后是否发生血栓分为血栓组(n=44)、未发生血栓组(n=81)。均行连续2点超声检查、血浆D-D水平检测,比较两组术后1、3、7 d股总静脉(CFV)及腘静脉(POV)血流速度、血浆D-D水平,探讨CFV、POV血流速度与血浆D-D水平相关性,分析连续2点超声、D-D联合对下肢骨折术后血栓的诊断价值。结果:血栓组术后3、7 d血浆D-D水平高于未发生血栓组,CFV、POV血流速度低于未发生血栓组(P<0.05);CFV、POV血流速度与血浆D-D水平呈负相关性(P<0.05);术后7 d血浆D-D水平、CFV、POV血流速度联合诊断下肢骨折术后血栓曲线下面积最大,为0.877,敏感性为93.18%,特异性为69.14%。结论:血浆D-D水平、连续2点超声联合检测可为临床诊断下肢骨折术后血栓、实施对症治疗提供有效辅助手段。
Objective:To analyze the diagnostic value of combined detection of continuous 2-point ultrasound and D-dimer(D-D)for suspected thrombosis after lower limb fractures.Methods:From January 2019 to October 2019,125 patients with lower limb fractures in our hospital were selected for elective surgery,they were divided into thrombus group(n=44)and non-thrombosis group(n=81)according to whether thrombosis occurred after surgery.All patients underwent continuous 2-point ultrasonography and plasma D-D level detection.The blood flow velocity of common femoral vein(CFV)and popliteal vein(POV)and plasma D-D level were compared between the two groups at 1,3,and 7 days after operation.The correlation between CFV and POV blood flow velocity and plasma D-D level was explored,and the diagnostic value of continuous 2-point ultrasound and D-D combined for thrombosis after lower limb fracture surgery was analyzed.Results:The plasma D-D level of the thrombus group was higher than that of the non-thrombosis group at 3 and 7 days after operation,and the blood flow velocity of CFV and POV was lower than that of the non-thrombosis group(P<0.05).The blood flow velocity of CFV and POV was negatively correlated with plasma D-D level(P<0.05).The area under the curve for the combined diagnosis of postoperative thrombosis of lower extremity fracture by plasma D-D level,CFV and POV blood flow velocity was the largest at 0.877,the sensitivity was 93.18%,and the specificity was 69.14%.Conclusion:The combined detection of plasma D-D level and continuous 2-point ultrasound can provide effective auxiliary means for clinical diagnosis of postoperative thrombosis of lower limb fractures and symptomatic treatment.
