BACKGROUND
Since graduated compression stockings (GCS) reduce the risk of deep venous thrombosis (DVT) in both hospital and ambulant patients, we checked the compressive efficiency of 20-30 mmHg GCS in the standing position.
METHODS
In 30 volunteers (17 normal legs, 13 varicose legs), duplex ultrasound was used to measure the internal diameters of the long saphenous vein, posterior tibial veins, peroneal veins, and soleal veins in the lying and standing position and with and without 20-30 mmHg GCS.
RESULTS
Graduated compression stockings effectively compressed both superficial and deep veins in supine individuals but not the superficial or the deep veins when standing. In the varicose leg, the stockings did not compress the long saphenous vein at the mid-calf level even when supine. In the varicose leg the long saphenous vein was constricted at the upper band of the stocking, which might explain why superficial venous thrombosis is more common when compression stockings are worn.
CONCLUSIONS
In the standing position, GCS did not compress the deep or superficial veins of the calf.
背景
由于分级压力弹力袜（GCS）可降低住院患者和门诊患者深静脉血栓形成（DVT）的风险，我们检测了20 - 30 mmHg的GCS在站立位时的压缩效率。
方法
选取30名志愿者（17条正常腿，13条静脉曲张腿），采用双功超声测量平卧位和站立位时，以及穿着和不穿着20 - 30 mmHg GCS时大隐静脉、胫后静脉、腓静脉和比目鱼肌静脉的内径。
结果
分级压力弹力袜能有效压缩仰卧位个体的浅静脉和深静脉，但在站立位时对浅静脉或深静脉均无压缩作用。在静脉曲张腿中，即使在仰卧位时，弹力袜也不能在小腿中部水平压缩大隐静脉。在静脉曲张腿中，大隐静脉在弹力袜的上缘处受压，这可能解释了穿着弹力袜时浅静脉血栓形成更为常见的原因。
结论
在站立位时，GCS不能压缩小腿的深静脉或浅静脉。
