摘　　要：目的:定量评估正常者与原发性下肢深静脉瓣功能不全(PIDVL)患者的下肢深静脉内径值及其返流持续时间、速度的比较,并确定PIDVL分级的新标准。方法:应用彩超测量并对比59例94条下肢(对照组)和30例39条下肢(观察组)深静脉内径值、返流持续时间及返流速度。结果:(1)观察组下肢深静脉内径值、股总静脉内径值、股浅静脉内径值、(?)静脉内径值明显大于对照组(均P<0.001)。(2)观察组下肢深静脉彩色脉冲多普勒(CPD)返流持续时间(PTR)、股总静脉PTR、朋静脉PTR明显大于对照组(均P<0.001)。(3)观察组下肢深静脉CPD返流速度(SR)与对照组比较无显著性差异(P>0.05)。(4)PIDVL分级与临床体征有密切相关性。结论:(1)正常者下肢深静脉返流持续时间确定为<1.2 s。(2)根据下肢深静脉内径值的大小及返流持续时间的长短将PIDVL程度分为3级。Objective: To diagnose and quantitatively analyse the primary insufficiency of deep vanous valve in lower extremity(PIDVL) with color pulse Doppler(CPD) .Methods: The internal diameter of deep vein, the speed of reflux(SR) and persistent time of reflux(PTR) were measured in 39 lower extremities of 30 cases (sickness group)and 94 lower limbs of 59 cases(control group). Results: (1)The internal diameters of deep vein in lower extremities, femoral common vein, femoral shallow vein and popliteal vein in sickness group were remarkably larger than those in control group (all P<0. 001) . (2) Using CPD, the PTRs of deep vein in lower limbs, femoral common vein and popliteal vein were remarkably larger than those in control group(all P <0.001) . (3) Between the 2 groups, there was not difference in the SR of deep vein in lower extremities(P> 0.05). (4)The grading of PIDVL was closely related to clinical signs. Conclusion: (1)The normal value of PTR of deep vein in lower extremities is determined to be lower than 1.2 s. (2) According to the size of internal diameter and the PTR of deep vein in lower extremities, the PIDVL is classed by 3 grades.
