青少年静脉血栓的超声特征

Ultrasonic Features of Juvenile Venous Thrombosis

目的分析青少年静脉血栓的发病原因及超声特征,为提高诊疗水平提供依据。资料与方法连续收集经血管超声确诊的135例青少年静脉血栓患者,分析其发病原因及超声特征。结果青少年静脉血栓患者男性居多(65.9%,89/135),青春期多发(73.3%,99/135)。主要发病原因为创伤(40.3%,31/77)、炎性疾病(15.6%,12/77)及肿瘤或血肿压迫(14.3%,11/77)。超声表现:静脉血栓主要发生于单侧肢体(86.7%,,117/135,P<0.01)、下肢深静脉(83.0%,112/135,P<0.01),以新鲜血栓为主(97.8%,132/135,P<0.01),梗阻程度多为完全充填型(59.3%,80/135,P=0.002)。结论青少年静脉血栓好发于单侧下肢深静脉,以急性新鲜血栓为主,梗阻程度严重者居多,主要致病因素包括创伤、炎症及肿块压迫。

Purpose To analyze the etiology and ultrasonic features of juvenile venous thrombosis(VT),so as to provide clinical basis for improving diagnosis and therapy.Materials and Methods 135 juvenile patients with VT diagnosed by vascular ultrasound were continuously collected,the etiology and ultrasonic features were analyzed.Results Juvenile VT occurred predominantly in boys(65.9%,89/135)and frequently in adolescence(73.3%,99/135).Trauma(40.3%,31/77),inflammatory diseases(15.6%,12/77)and tumor or hematoma compression(14.3%,11/77)were main reasons caused thrombosis.Juvenile VT mostly occurred in unilateral lower limbs(86.7%,117/135;P<0.01),deep veins(83.0%,112/135;P<0.01)and fresh thrombosis was predominant(97.8%,132/135;P<0.01),and the degree of obstruction was mostly completely filled(59.3%,80/135;P=0.002).Conclusion Juvenile VT mainly occurs in unilateral deep veins of lower extremities,most are fresh thrombosis,with severe obstruction,and the main causes are trauma,inflammatory and compression.Ultrasound doctors should improve their understanding of juvenile VT,for early diagnosis,treatment and improve prognosis.
