摘要
目的:本研究应用彩超对下肢静脉瓣功能不全的患者行卧位及站立位检查,通过比较两种检查方法超声参数的差异,确定彩超检查下肢静脉瓣功能不全的最佳检查体位。方法:通过彩色多普勒超声对试验组25例患者的39条患肢与正常组10例的12条健康下肢均采用卧位及站立位检查,大隐静脉、股总静脉、股浅静脉用Valsalva运动诱导返流,腘静脉用挤压法诱导返流;对比观察不同体位每一下肢的返流时间、总返流时间、返流峰值流速、总的返流峰值速度、每一肢体总的返流节段数、静脉管径等参数。结果:正常组无论卧位及站立位所有节段返流时间<0.5s,无返流。病例组站立位与卧位下肢静脉返流节段数的比较,二者的差异无统计学意义;卧位总返流时间比较,二者差异有统计学意义;总返流速度的比较;二者差异无统计学意义;病例组与正常组卧位及站立位GSV、CFV、SFV、POPV管径比较,差异有统计学意义。结论:对静脉瓣功能不全的超声检查两种体位均可采用,卧位检查医生操作更方便,而对于年老体弱、不能久站者,卧位检查则应为首选。
Objective： This study was undertaken to explore different patient positions （supine position and standing position） by color Doppler flow image（CDFI） measuring chronic venous incompetence（CVI） quantitatively. Methods： Thirty-nine impaired lower limbs in 25 patients and 12 healthy limbs in 10 patients were tested in supine position and standing position. Great saphenous vein （GSV）, common femoral vein （CFV） and superficial femoral vein （SFV） were evoked reflux by Valsalva method, and popliteal vein （POPV） by compression maneuver. Reflux time （RT, s） and peak reflux velocity （PRV, cm/s） were measured. The total RT, total PRV and the number of reflux segments were calculated. Results： All of the segments＇ RT are less than 0.5s despite supine position and standing position in healthy group. No meaningful difference about the number of reflux segments is found between supine and upright. The overall RT of supine position is significantly longer than that of standing position. The overall PRV has no significant difference between supine and standing position. The diameters of GSV, CFV, SFV and POPV of the patients and healthy group in standing position are significantly wider than that in supine position. Conclusion： We can evaluate CVI by CDFI with patients in supine position or upright, but it is more convenient that the patients are in supine position. Supine position might be the first choice for detecting CVI for the old, incapable and the person who can not stand for long time.
