摘要:


文题释义:

血栓弹力图:是反映血液凝固动态变化的指标,主要有凝血反应时间、凝固时间、凝固角、最大振幅、综合凝血指数,临床上用于动静脉血栓形成、冠心病、血小板减少症等相关性疾病的检查。
平均血小板体积:是采用自动化血细胞分析仪得到的一项临床检测指标,属于血常规检查。正常参考值:9.0-13 fL。平均血小板体积的变化有助于鉴别血小板减少的原因。近年来相关研究显示平均血小板体积的升高与血栓形成有一定相关性。


背景:血栓弹力图对于识别人体血液高凝状态及血栓方面起重要作用,近年来有研究表明平均血小板体积升高与血栓有一定相关性,那么血栓弹力图与平均血小板体积的联合诊断对血栓预测是否更加准确。

目的:通过平均血小板体积联合血栓弹力图来预测全膝关节置换后血液的状态及血栓的发生情况。
方法:收集2015年5月至2022年3月间接受单侧全膝关节置换的患者120例,根据术后第7天的超声检查结果将患者分为血栓组60例,对照组60例。分别于术前1 d、术后第1天和第7天进行全血细胞和血栓弹力图检查,采用多因素分析全膝关节置换后血栓发生的独立预测因子,并测定受试者工作特征曲线和曲线下面积。

结果与结论:平均血小板体积与最大振幅的相关性最强,凝固角其次;术后第1天的平均血小板体积、凝固角是血栓发生的独立预测因子,血栓患者平均血小板体积呈先上升后下降的趋势;平均血小板体积预测血栓的最佳临界值是10.73 fL,受试者工作特征曲线下面积为0.665(95%CI:0.568-0.762,P < 0.05);而采用平均血小板体积联合凝固角的受试者工作特征曲线下面积为0.815(95%CI:0.750-0.879,P < 0.05);此外,血栓组术后的最大振幅、凝固角、综合凝血指数、平均血小板体积均高于对照组,差异有显著性意义(P < 0.05)。结果表明:平均血小板体积可以反映术后血液的高凝状态,全膝关节置换后第1天平均血小板体积与凝固角的联合使用可提高对血栓形成的预测能力。

Abstract: BACKGROUND: Thromboelastography plays an important role in identifying the hypercoagulable state of blood and thrombosis in humans. Recent studies have shown a correlation between an increase in mean platelet volume and thrombosis. We can therefore ask whether the combined diagnosis of thromboelastography and mean platelet volume is a more accurate predictor of thrombosis. 
OBJECTIVE: To predict the status of blood and the occurrence of thrombosis after total knee arthroplasty by means of mean platelet volume combined with thromboelastography.
METHODS: One hundred and twenty patients who underwent unilateral total knee arthroplasty between May 2015 and March 2022 were collected. Patients were divided into 60 patients in the thrombosis group and 60 patients in the control group based on ultrasound findings on postoperative day 7. Whole blood cell and thromboelastography were performed 1 day before, 1 and 7 days after surgery, respectively. Multifactorial analysis was used to investigate independent predictors of thrombosis after total knee arthroplasty. The receiver operating characteristic curve and area under the curve were measured in the subjects.
RESULTS AND CONCLUSION: Mean platelet volume correlated most strongly with maximum amplitude, followed by coagulation angle. Mean platelet volume and coagulation angle on postoperative day 1 were independent predictors of thrombosis. Mean platelet volume tended to rise and then fall in patients with thrombosis. The best critical value for mean platelet volume to predict thrombosis was 10.73 fL. The area under the receiver operating characteristic curve of subjects was 0.665 (95%CI: 0.568-0.762, P < 0.05]; whereas the area under the receiver operating characteristic curve for subjects using mean platelet volume combined with coagulation angle was 0.815 (95%CI: 0.750-0.879, P < 0.05). In addition, the maximum amplitude, coagulation angle, coagulation index and mean platelet volume were significantly higher in the thrombosis group than in the control group postoperatively (P < 0.05). The results suggest that the mean platelet volume can reflect the hypercoagulable state of blood after surgery, and the combination of mean platelet volume and coagulation angle on day 1 after total knee arthroplasty can improve the prediction of thrombosis.

Key words: thromboelastography, mean platelet volume, deep vein thrombosis, total knee arthroplasty
