摘　　要：目的:探讨股静脉搏动性血流频谱(PFVF)与下腔静脉塌陷指数(IVC-CI)之间的关系。方法:选取2016年1月~12月在中日友好医院超声诊断科进行下肢静脉超声检查的患者80例,其中PFVF和非PFVF组患者各40例,分别测量IVC-CI,然后对比分析两组之间的统计学差异。结果:PFVF组和非PFVF组的IVC-CI分别为0.40±0.14和0.63±0.08,两组之间比较差异有统计学意义(t=8.814,P=0.000,差分的95%置信区间:0.176~0.279)。结论 :股静脉搏动性血流频谱与下腔静脉塌陷指数之间有一定的相关性。Objective：To investigate the relationship between pulsatile femoral venous flow （PFVF）and inferior vena cava collapse index（IVC-CI）.Methods：Eighty cases from January 2016 to December 2016 were enrolled in this study and all the cases had undergone lower extremity vein scans in the Ultrasound Department of China-Japan Friendship Hospital.They were divided into two groups：PFVF group and non-PFVF group,each had 40 cases.The IVC-CIs of both groups were calculated and analysed statistically.The method of IVC-CI calculation：in a supine position,the ultrasound probe was placed on the right side of the xiphoid,then,the anteroposterior diameter of the inferior vena cava was measured at a distance of 2.0 em from the right atrium. The maximum diameter （Dmax）and the minimum diameter （Drain）of the the inferior vena cava were recorded respectively.The IVC-CI was measured three times and the average value was calculated.How to determine a PFVF？ First,in a supine position and normal respiration,gray-scale ultrasound was applied to find the entrance of right great saphenous vein into the common femoral vein,then Doppler sampling was placed at the top of the entrance 1.0cm^2.0cm.PW mode was opened and the common femoral venous flow spectrum was recorded.PFVF was determined when there was a spectrum periodically changed with the heart beat.Results： The IVC-CI of PFVF group and non-PFVF group were 0.40-＋0.14 and 0.63~0.08,respectively.There was significant difference between two groups （t=8.814,P=0.000,95% confidence interval for difference：0.176~ 0.279）.Conclusion：There is a correlation between IVC-CI and PFVF.
