Intravascular Effect Of Circumferential Compression

Direct observation using ultrasound has shown that compression stockings of 35 mm Hg have no noticeable effect on the morphology or function of large varicose veins. Since the vein preserves its dimensions, there is nothing to prevent the formation of a thrombus. Even when rolls of gauze or other nonelastic cylinders are placed on the varicose vein and strongly compressed by a bandage of little elasticity (Peha-Haft®; Hartmann), no reduction in the diameter of trunk varicose veins is produced on standing. Thus, the joint application of these compressive measures (i.e., stocking + bandage + nonelastic cylinders) does not occlude the lumen of the vessel.
