| 中文摘要:目的: 研究常规止血带下单侧膝关节镜术后早期DVT的发生率并探讨分析其发生的相关危险因素。方法:回顾性分析2013年1月到2017年1月住院接受单侧膝关节镜手术的符合纳入排出标准的所有患者共1561例，其中男651例，女910例，年龄62-81岁（平均65.7±8.7岁），根据术后超声将患者分为DVT组和非DVT组，统计分析术后早期的DVT发生率，通过单因素及多因素分析筛选出能够预测DVT发生的危险因素。所有出现DVT的患者常规抗凝治疗6个月，并于初次诊断后1,3,6个月门诊随访，行超声多普勒检查再次评估。结果:1561例患者中226例（14.5%）出现DVT。其中发生在近端的DVT患者32例(2.0%)，单独发生在肢体远端的DVT患者194例（12.4%）。术后DVT的危险因素包括高龄（≥73岁），女性，腓肠肌静脉扩张，高血压，止血带使用时间（≥74min）。 腓肠肌静脉扩张和止血带使用时间是预测DVT发生率的较强独立危险因素，OR值分别为2.337（95%CI,1.644-3.611）和2.112(95%CI, 1.452-3.301)。6个月门诊随访发现12例远端DVT(6.6%)和8例近端DVT(26.7%)仍然表现为血栓，但体积减小并出现不同程度的溶解。结论:常规止血带下接受膝关节镜手术后早期DVT的发生率为14.5%，在所有因素中，腓肠肌静脉扩张和止血带使用时间是术后DVT发生的较强预测因素。无论是近端DVT还是远端DVT经过及时正规治疗后效果都较为满意。 |

| occurrence and risk factors of early DVT among patients undertaken knee arthroscopic surgery with routine use of tourniquet |
|
| ABSTRACT Objective: To find out the incidence of early DVT in patients after knee arthroscopic surgery with routine use of tourniquet and discuss the associate risk factors. Methods：1561 cases undertaken primary knee arthroscopic surgery was reviewed retrospectively from January 2013 to January 2017. There were 651 males and 910 females, aging from 62-81 years（mean，65.7±8.7 years）.The cases were divided into DVT group and non-DVT group according to ultrasonic Doppler after surgery. The DVT occurrence rate was calculated and the basic information was analyzed to filter out the risk factors through univariate analysis and multivariate analysis. The cases of DVT group received 6 month anticoagulation therapy and were undertaken a follow-up of 1,3,6 months by ultrasonic Doppler. Results：Out of the 1561 cases,226(14.5%) developed early DVTs following surgery. 32 (2%) cases had the proximal DVTs, and 194 (12.4%) cases had the isolated distal DVTs. The risk factors include the age(≥73 years), female sex and gastrocnemius vein dilation (GVD)，hypertension，longer tourniquet time（≥74min）.The GVD and the length of tourniquet time is considered to be the best predictor of the early DVTs after surgery, with an odds ratio of 2.337 (95% CI, 1.644–3.611) and 2.112(95%CI, 1.452-3.301). 12 isolated distal DVTs（6.6%）and 8 proximal DVTs（26.7%）still showed thrombus at 6-month follow-up, but exhibit decreased size and at various stage of resolution. Conlusion: The incidence of early DVTs after knee arthroscopic surgery is 14.5%, Out of all risk factors, the GVD and the length of tourniquet time have the best power for prediction of DVTs after surgery. Both proximal and distal DVTs received accepted outcomes after formal therapy. |
