Background: Strain gauge plethysmography (SGP) is employed to evaluate venous drainage of the lower leg.
Methods: In this study, SGP was used to evaluate the effects of the hydrostatic pressure (HP) of water on venous volume (VV), expelled volume, and ejection fraction (EF) in 22 healthy legs before and during immersion in water.
Results: HP reduced VV by 100% and even more during underwater (UW) exercise, making calculation of the UW EF possible.
Venous intima-media thickness increases both in deep and superficial systems in patients with great saphenous vein reflux.

Objective: To evaluate by Doppler ultrasound (DUS) the venous intima-media thickness (vIMT) in patients with or without great saphenous vein (GSV) incompetence.
Methods: A prospective vIMT measurement was performed by DUS in an outpatient cohort. Patients were divided in two groups: group A, patients without GSV reflux; and group B, patients with at least one refluxing GSV.
Objectives: Hydrostatic compression (HC) occurring during body immersion is considered beneficial for venous return from the lower limbs. No study has evaluated the effects of HC on the veins of the lower limbs using duplex ultrasound (DU). The purpose of this study was to use DU to evaluate the morphology and flow of the leg veins during immersion.

Methods: Between May 2010 and March 2012, 67 patients (78% males) were treated by Zilver PTX, because of stenosis or occlusions of the superficial femoral artery in one of two centers. The mean age of patients was 70.
