交通支功能不全在下肢静脉曲张皮肤病变中的作用

Effect of perforative vein insufficiency with skin damage of varicosity in the lower extremity

采用静脉容积描记检测49例(62条)下肢静脉曲张患者,结果表明:交通支功能不全组,静脉回复时间(VRT),节段性静脉容积(SVC)和静脉最大回流量(MVO)与交通支功能正常组对照有显著性差异(P<0.01),皮肤营养障碍时,交通支功能不全占75.9%。结果提示:交通支功能不全时,异常血流动力学改变是导致皮肤病变的重要原因,结扎功能不全的交通支是治疗皮肤病变的基础。

Using venous plethysmography,49patients(62 limbs)with varicosity in lower extremity were tested.The results showed Venous Refill Time(VRT),segment venous capacititance(SVC)and maximum venous outflow(MVO)of perforative vein insufficiency compared with those of normal perforative vein.The differences were significant (P<0.01).The perforative vein insufficiency with skin damage occurred in 75.6%.These suggested that changes of hemodynamics in perforative vein insufficiency is an important reason of skin damage.It's a basis to handle the perforative vein insufficiency in the treatment if skin damage.
