摘要:

背景:文献报道各种对深静脉血栓形成的诊断方法,但是结合危险度预测评分系统及多种实验室指标对深静脉血栓形成的预测诊断率的提高尚不明确。
目的:使用Wells评分系统并结合D-二聚体及纤维蛋白降解产物提高诊断创伤后下肢深静脉血栓敏感性。
方法:下肢骨折及脊柱骨折患者82例,排除患病前合并深静脉血栓形成高危因素的患者及曾患有深静脉血栓形成的患者。入院后检测患者D-二聚体、纤维蛋白酶原降解产物、纤维蛋白酶原、凝血酶原时间、部分活化凝血酶原时间、血小板计数、C-反应蛋白及血沉相关指标,并做彩色多普勒下肢超声检测。根据下肢深静脉栓塞评分表(Wells评分表)评分分为低危、中危及高危患者。
结果与结论:彩色多普勒下肢超声检测深静脉血栓形成组30例;非深静脉血栓形成组52例,两组患者D-二聚体及纤维蛋白降解产物的峰值差异有显著性意义(P < 0.05)。Wells评分低危患者13例、中危32例、高危37例,D-二聚体及纤维蛋白降解产物对诊断深静脉血栓形成的诊断正确率:中危患者深静脉血栓形成阳性预测值为44.44%,而高危患者的深静脉血栓形成阳性预测值为70.97%。logistic回归分析显示Wells评分中危及高危组实验室指标与下肢静脉彩色多普勒超声检查结果均为正关联(P < 0.05)。结果表明Wells评分结合D-二聚体及纤维蛋白降解产物对预测创伤后下肢深静脉血栓的形成有临床意义。

Abstract:

BACKGROUND: Diagnosis of deep venous thrombosis has been reported in the literatures, but whether the combination with risk prediction scoring system and a variety of laboratory index increase the diagnosis rate of deep venous thrombosis remains unclear.
OBJECTIVE: To improve the diagnosis sensitivity of traumatic deep venous thrombosis of lower extremity using Wells scoring system combined D-dimer and fibrin degradation product.
METHODS: A total of 82 patients with low limb fractures and spine fracture were included in this study, those patients with high risk factors of deep venous thrombosis or with the history of deep venous thrombosis were excluded. After admission, the following indicators of deep venous thrombosis were determined, including D-dimer, fibrin degradation product, fibrinogenase, prothrombin time, activated partial thrombokinase time, blood platelets count, C-reaction protein, and erythrocyte sedimentation rate. In addition, Doppler ultrasound detection of double lower limbs deep vein was performed, and the results were recorded. According to scoring system of deep venous thrombosis of lower extremity (Wells scoring system), the patients were assigned into low-risk, middle-risk and high-risk cases.
RESULTS AND CONCLUSION: Doppler ultrasound detection showed that, there were 30 cases in deep venous thrombosis group, and 52 cases in non-deep venous thrombosis. The peak value of D-dimer and fibrin degradation product showed significant differences between the two groups (P < 0.05). According to Wells  scoring system, there were 13 low-risk cases, 32 middle-risk cases, and 37 high-risk cases. The diagnosis rate of deep venous thrombosis using D-dimer and fibrin degradation product: positive prediction value for middle-risk deep venous thrombosis was 44.44% and for high-risk deep venous thrombosis was 70.97%. Logistic regression analysis showed that, in the middle-risk and high-risk deep venous thrombosis cases, the Wells score has a positive correlation with laboratory test and Doppler ultrasound detection of deep venous thrombosis (P < 0.05). The score of Wells scoring system combined D-dimer and fibrin degradation product have clinical significances for the formation of deep venous thrombosis of lower extremity after trauma.
