Noninvasive evaluation of chronic venous insufficiency. Use of foot mercury strain-gauge plethysmography. 1984

H Schanzer, and L Lande, and G Premus, and E C Peirce

Twenty-seven patients (40 extremities) with chronic venous insufficiency and 30 controls (60 extremities) were studied using noninvasive measurements of foot volume (foot mercury strain-gauge plethysmography [FMSGP]). Tests were performed with exercise (sitting) and with elevation (Trendelenburg), with and without tourniquets, to evaluate muscle pump efficiency and valvular competence. Empiric venous sufficiency indexes were calculated for exercise and for Trendelenburg's test. Test results were compared with invasive ambulatory venous pressure (AVP) data (13) and with ascending and retrograde venography (25). Distinctive plethysmographic patterns revealed the insufficiency was saphenous (four), calf perforators (14), saphenous plus perforators (seven), and deep venous (15), including occlusion (four). Correlation with AVP and venography was good but FMSGP was more discriminating, providing precise anatomical information, better reproducibility, and distinguishing poor muscle pump function from regurgitation. Patients accept FMSGP well. Repeated postoperative data are readily obtained for evaluation of surgical procedures.

D008628	Mercury	A silver metallic element that exists as a liquid at room temperature. It has the atomic symbol Hg (from hydrargyrum, liquid silver), atomic number 80, and atomic weight 200.59. Mercury is used in many industrial applications and its salts have been employed therapeutically as purgatives, antisyphilitics, disinfectants, and astringents. It can be absorbed through the skin and mucous membranes which leads to MERCURY POISONING. Because of its toxicity, the clinical use of mercury and mercurials is diminishing.

D002908	Chronic Disease	Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).

D005080	Exercise Test	Controlled physical activity which is performed in order to allow assessment of physiological functions, particularly cardiovascular and pulmonary, but also aerobic capacity. Maximal (most intense) exercise is usually required but submaximal exercise is also used.

D014689	Venous Insufficiency	Impaired venous blood flow or venous return (venous stasis), usually caused by inadequate venous valves.
