目的探讨儿童创伤后下肢深静脉血栓(DVT)的临床特点及治疗方法。方法对10例儿童创伤后经双下肢深静脉彩色多普勒超声确诊发生DVT后采用低分子肝素钙联合物理治疗。结果本组儿童创伤后DVT的发生率为1.28%,发生的时间于伤后1~6 d,术前发现9例,术后第2天发生1例。经治疗后随访3～15个月,均未再发生血栓及有症状的肺栓塞。结论儿童DVT的出现,打破了以往认为16岁以下儿童罕见发生DVT的理论,对于年龄偏大、创伤严重的儿童患者一定要重视下肢深静脉血栓的诊断、预防及治疗。
Objective To investigate the clinical characteristics and treatment of traumatic lower extremity deep venous thrombosis (DVT) in children. Methods Totally 10 children with post-traumatic DVT were diagnosed by color Doppler ultrasonography of deep vein of both lower extremities and low molecular weight heparin combined with physical therapy. Results The incidence of posttraumatic DVT in this group was 1.28%. The occurrence time was 1 ~ 6 days after injury. Nine cases were found preoperatively and one case occurred on the second day after operation. After treatment, follow-up 3 to 15 months, no recurrence of thrombus and symptomatic pulmonary embolism. Conclusion The appearance of DVT in children broke the previous theory that children under 16 years old rare DVT, for older patients with severe trauma children must pay attention to the diagnosis, prevention and treatment of deep vein thrombosis.
