目的：回顾分析脊髓损伤患者下肢深静脉血栓预防情况。方法对2015年4~5月本院115例脊髓损伤患者血栓性疾病相关资料进行回顾，收集临床症状、下肢深静脉彩超、实验室检查等资料，分析血栓发生情况及预防措施、血栓发生部位及处理方法。结果在外院曾接受血栓预防43例，入本院后接受血栓预防105例。在外院发生有临床症状的下肢深静脉血栓9例，未发生肺栓塞；在本科发生下肢深静脉血栓者3例，未发生肺栓塞。外院发生和未发生下肢深静脉血栓患者的大多数实验室指标无显著性差异(P>0.05)。外院曾进行血栓预防措施的患者43例，未进行过预防的患者72例，发生下肢深静脉血栓的人数分别是5例和4例，外院是否行血栓预防措施与血栓发生不相关(χ2=0.663, P=0.415)。53例完全性脊髓损伤患者中，5例出现下肢深静脉血栓；59例不完全性脊髓损伤患者中，4例出现下肢深静脉血栓，发生下肢深静脉血栓与脊髓损伤的严重程度不相关(χ2=0.028, P=0.867)。结论进行血栓预防的患者也会发生下肢深静脉血栓。实验室检查对于预测和诊断下肢深静脉血栓特异性不充分。“,”Objective To retrospectively analyze the lower extremity deep vein thrombosis prevention in patients with spinal cord injury (SCI). Methods A total of 115 SCI patients in our department from April to May, 2015 were included. The clinical symptoms, lower limb deep vein ultrasonic testing, laboratory examination were collected to analyze the occurrence, prevention measures, the thrombus location and management of deep venous thrombosis (DVT) in lower limbs. Results Forty-three patients had thromboprophylaxis in other hospitals before admission, and 105 patients in our department after admission, in which, nine cases were with clinical symptoms in other hospitals and three cases in our department. No pulmonary embolism occurred in them. There was no significant difference in most laboratory index-es between patients with DVT and without DVT in lower limbs (P>0.05). Five patients were with DVT in lower limbs in 43 patients who had thromboprophylaxis, and four cases in 72 patients who did not have thromboprophylaxis. No relationship was found between thrombo-prophylaxis and DVT in lower limbs (χ2=0.663, P=0.415). Five patients were with DVT in lower limbs in 53 patients with complete SCI, and four cases in 59 patients with incomplete SCI. No relationship was found between the severity of SCI and DVT in lower limbs in other hospitals (χ2=0.028, P=0.867). Conclusion DVT in lower limbs could be also occurred in patients who accepted thromboprophylaxis. Labo-ratory indexes are inadequate for the prediction and diagnosis specificity of DVT in lower limbs.
