【摘要】：目的初步探讨静脉瘀滞指数等超声指标对膝、髋关节置换术后下肢深静脉血栓风险的评估。方法选取行膝、髋关节置换术的患者100例,检测患者术前股总静脉内径和流速、股总动脉内径、比目鱼肌静脉内径,计算股总静脉瘀滞指数及静脉、动脉内径比,并检测术后1、2、3、7d患者有无下肢深静脉血栓。结果 (1)发生血栓患者57例,患肢78条,血栓发生率为57%,均发生于小腿部,以比目鱼肌静脉为主,74%的患者血栓发生于术后第一天;(2)血栓组股总静脉瘀滞指数高于无血栓组(7.75±2.79vs 5.92±3.49,P0.05),差异有统计学意义;(3)血栓组股总静脉血流速度低于无血栓组、内径大于无血栓组(P0.05);血栓组比目鱼肌静脉内径大于无血栓组(P0.05);(4)两组的股总静脉、动脉内径比差异无统计学意义(P0.05)。结论血栓组和无血栓组术前瘀滞指数等超声指标有显著差异,将其用于术前检测对于术后血栓风险评估有重要意义。
[Abstract]:Objective to evaluate the risk of deep venous thrombosis after knee and hip arthroplasty with ultrasound indexes such as venous stasis index. Methods 100 patients undergoing knee and hip arthroplasty were selected. The internal diameter and velocity of the common femoral vein, the internal diameter of the common femoral artery, the internal diameter of the soleus muscle vein were measured before operation, and the stagnation index of the common femoral vein and the ratio of the internal diameter of the vein to the artery were calculated. The deep vein thrombosis of lower extremity was detected in patients with 3 days after operation. Results (1) 57 cases of thrombus occurred in 78 limbs and 57 cases of thrombus occurred in the lower leg. The blood stasis index of the total femoral vein in the thrombus group was higher than that in the non-thrombus group (7.75 卤2.79vs 5.92 卤3.49 P0.05). The difference was statistically significant (P < 0.05). The blood flow velocity of the total femoral vein in the thrombus group was lower than that in the non-thrombus group. The internal diameter of the total femoral vein in the thrombus group was larger than that in the thrombus group (P 0.05), and there was no significant difference in the arterial diameter ratio between the two groups (P 0.05). Conclusion there is significant difference in preoperative blood stasis index between thrombus group and non-thrombus group, and it is important to evaluate the risk of thrombus after operation.
