摘　　要：目的探讨最大静脉回流量测定在下肢深静脉血栓形成(DVT)诊断中的价值。方法采用多功能血管诊断仪对100例正常人的166条下肢进行最大静脉回流量测定,对46例确诊的DVT 患者的患肢和健侧肢体进行测定,并对患肢进行上行性静脉造影,作对比研究。采用静脉容积(VC)、 2 s静脉回流量(VO)和最大静脉回流比率(MVOR,即VO／VC)3个指标。结果测得的正常MVOR 为1．08±0．18,无明显性别及年龄差别。患肢的MVOR明显降低,为0．69±0．14,与上行性静脉造影结果相符。结论 MVOR对DVT有明确的诊断价值,MVOR<0．9或者与健侧比较差值大于或等于 0．2即可作出DVT的诊断。Objective To determine the maximum venous outflow of the lower extremity deep veins in case of deep venous thrombosis （ DVT ）. Method We use IMEX9000 multi-function vascular diagnosis instrument to examine 166 lower extremities of 100 controls the maximum venous outflow. The measurement was carried on in 46 diagnosed DVT cases for healthy and diseased limbs. Ascending venography was also performed. Three indicators were adopted including venous capacitance（VC） , 2 second venous outflow（ VO ） and maximum venous outflow ratio （MVOR, namely VO/VC ）. Result Normal MVOR is 1.08 ± 0. 18, irrespective of age and gender. MVOR drops significantly in diseased limb （0. 69 ± 0. 14）, paralleling with the result of ascending venography. Conclusion MVOR has the explicit diagnosis value for lower extremity deep venous thrombosis. A MVOR 〈 0. 9 or a MVOR ratio≥0. 2 when compared with contralateral healthy limbs is definitely diagnostic of DVT.
