摘　　要：目的研究体质指数对下肢慢性静脉功能不全患者下肢动态静脉压的影响。方法对102例下肢慢性静脉功能不全患者的体质指数和下肢动态静脉压进行测定和比较，其中体重正常组28例，超体重组43例，肥胖组31例。结果肥胖组和超体重组比体重正常组更容易出现色素沉着、湿疹、皮肤硬化和溃疡等下肢慢性静脉功能不全并发症。肥胖组、超体重组和体重正常组静息压（P0）分别为（118．0±11．5）、（113．0±9．7）、（101．0±10．6）mmHg（1mmHg=0．133kPa）；不挤压后4s时压力（4SP）分别为（75．00±2．99）、（71．00±3．01）、（65．00±2．17）mmHg；压力降低百分比（pd）分别为（35．0±5．4）％、（39．0±4．3）％、（43．0±5．1）％；压力自挤压后静脉压开始恢复至P0的50％所需时间（R1k）分别为（7±1）、（9±2）、（12±3）s。肥胖组和超体重组P0和4SP比体重正常组明显升高（P〈0．05），肥胖组和超体重组Pd比体重正常组明显降低（P〈0．05）；在静脉压力逐渐恢复过程中，肥胖组和超体重组比体重正常组RT50明显缩短（P〈0．05）。结论随着体质指数升高，下肢慢性静脉功能不全患者的下肢慢性静脉功能不全程度更严重。Objective To study the influence of body mass index on ambulatory venous pressure of chronic venous insufficiency of lower extremity. Methods One hundred and two consecutive patients with chronic venous insufficiency of lower extremity were enrolled in this study. Ambulatory venous pressure and body mass index were assessed and compared. Normal body weight group had 28 cases, over weight group had 43 cases, obesity group had 31 cases. Results The complication of pigmentation, eczema, skin sclerosis and ulcer were more in obesity group and over weight group than those in normal body weight group. The resting pressure （P0） in obesity group, over weight group and normal body weight group were （ 118.0 ±11.5 ）, （ 113.0 ± 9.7 ）, （ 101.0 ± 10.6 ） mm Hg （ 1 mm Hg = 0.133 kPa ）, the pressure after unclamp 4 s （ 4SP ） were （75.00 ± 2.99）, （71.00 ± 3.01 ）, （65.00 ± 2.17） mm Hg, the percentage of decreased pressure（Pd） were （ 35.0 ± 5.4）%, （39.0 ± 4.3 ）%, （43.0 ± 5.1 ）%, the time of P0 recovered 50%（RT±o） were （7 ± 1 ）, （9 ± 2）, （ 12± 3） s. The Po and 4SP in obesity group,over weight group were significantly higher than those in normal body weight group （P 〈 0.05）. The Pd, RT50 in obesity group,over weight group were significantly lower than those in normal body weight group （P 〈 0.05 ）. Conclusion With the increasing of body mass index , the chronic venous insufficiency of lower extremity is more severity.
