ABSTRACT

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.Resets 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％ (RT50) were(7 ± 1),(9 ± 2),(12 ± 3) s.The P0 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.
