对比研究上、下肢关节镜术后患者深静脉血栓(DVT)的发生情况，同时寻找引起上、下关节镜术后患者发生下肢DVT的危险因素，为关节镜术后DVT的评估及预防提供可靠的临床参考依据。

回顾性收集晋江市医院2021年10月至2022年10月接受关节镜手术患者的一般资料及相关实验室指标，包括年龄、身体质量指数(BMI)、术后Caprini评分和术后D-二聚体等。排除术前彩超显示深静脉血栓的患者。根据不同的暴露因素，分为DVT组和无DVT组。暴露因素为计量资料的采用独立样本t检验、暴露因素为计数资料采用卡方检验，找出两组间差异具有统计学意义的可能危险因素进行修正Poisson回归分析。

共有232例患者纳入本研究，其中有25例(10.8%)术后并发下肢DVT，均为远端DVT，其中小腿肌间静脉24例，胫后静脉合并胫前静脉1例，无一例术后发生肺栓塞(PE)；上、下肢关节镜术后DVT的发生率差异无统计学意义(P>0.05)。与无DVT组相比，年龄(t＝－2.140)、BMI(t＝－2.592)、术后Caprini评分(t＝－6.410)、手术时长(χ²＝12.262)、止血带使用时长(χ²＝6.812)、和术后D-二聚体(χ²＝7.719)的差异均具有统计学意义(均为P<0.05)。修正Poisson回归分析显示：BMI增加[相关危险度(RR)＝1.235，95%置信区间(CI)(1.084，1.408)，P<0.01]、术后Caprini评分增加[RR＝1.080，95%CI(1.062，1.312)，P<0.01]和术后D-二聚体升高[RR＝3.657，95%CI(1.465，9.130)，P<0.01]，是术后DVT的危险因素。

上肢关节镜术后DVT的发生率不低于下肢关节镜术后DVT的发生，应引起临床医生的重视；BMI增加、术后Caprini评分增加和术后D-二聚体升高都是DVT发生的重要危险因素。

To compare the occurrence of DVT and identify the risk factors in patients after arthroscopic surgery for upper and lower limbs, providing reliable clinical reference for the evaluation and prevention of DVT after arthroscopic surgery.

Retrospective analysis was conducted to collect general information and relevant laboratory indicators of patients undergoing arthroscopic surgery in Jinjiang Hospital from October, 2021 to October, 2022. The patients with DVT displayed by color ultrasound before operation were excluded. According to different exposure factors, they were divided into DVT group and non-DVT group. To explore the risk factors that cause DVT after arthroscopic surgeries in upper and lower limbs, independent sample t test was used for measurement data of exposure factors, and chi square test was applied for counting data to identify potential risk factors. Modified Poisson regression analysis was performed on potential risk factors with statistically significant differences between the two groups.

A total of 232 patients were enrolled. Among them, 25 (10.8%) had postoperative DVT in lower limb, and all were distal DVT. Among these 25 patiens, 24 cases were intermuscular veins in the calf, one case was posterior tibial vein combined with anterior tibial vein, and no postoperative pulmonary embolism (PE) occurred. There was no statistically significant difference in the incidence of DVT between upper and lower limb arthroscopy surgerie. Compared with the non-DVT group, there were statistically significant differences in age(t=-2.140), BMI(t=-2.592), postoperative Caprini score(t=-6.410), the duration of operation(χ²=12.262), the duration of using tourniquet(χ²=6.812), and postoperative D-dimer(χ²=7.719)(all P<0.05 ). Modified Poisson regression analysis showed that increased BMI [relative risk(RR)=1.235, 95%confidence interval(CI) (1.084, 1.408), P<0.01), postoperative Caprini score (RR=1.080, 95%CI(1.062, 1.312), P<0.01) and postoperative D-dimer increase (RR=3.657, 95%CI(1.465, 9.130), P<0.01) were risk factors for postoperative DVT.

The incidence of DVT after arthroscopy in upper limb is not lower than that after arthroscopy in lower limb, which should be taken seriously by clinical doctors. An increase in BMI, postoperative Caprini score, and postoperative D-dimer elevation are important risk factors for the occurrence of DVT.
