Venous Valvular Insufficiency Testing
Sergio X. Salles Cunha and Diana L. Neuhardt
KEY TERMS
B-mode ultrasound imaging | chronic venous insufficiency | color flow ultrasound imaging | duplex Doppler | plethysmography | varicose veins | venous reflux | venous valvular insufficiency
GLOSSARY
anterior accessory saphenous vein superficial vein at the anterior thigh
CEAP clinical, etiologic, anatomical, and patho- physiological classification of chronic venous insufficiency
chronic venous insufficiency a long-lasting venous valvular or obstructive disorder
elastic compression effect of stockings used to compress the leg with the intent to compress the veins
great saphenous vein superficial vein in the medial thigh and calf
leg edema leg swelling due to the accumulation of water or fluid
lipedema swelling attributed to fat tissue lymphedema swelling attributed to lymph chan-
nels or lymph node disorders
plethysmography graphic presentation of pulses such as changes in volume within an organ or other part of the body such as a leg
posterior accessory saphenous vein superficial vein at the posterior thigh
reflux reverse flow, usually in veins with incompetent valves
reticular veins veins with a diameter less than 3 mm
small saphenous vein superficial vein in the posterior calf
spider vein inadequate name for purple or red telangiectasias, an arteriovenous rather than a venous disorder
superficial epigastric vein tributary of the proximal great saphenous vein
telangiectasia dilation of red, blue, or purple superficial capillaries, arterioles, or venules located below the skin’s surface; see spider vein
varicose veins veins with a diameter equal or greater than 3 mm
vein of Giacomini communicating vein between the great and small saphenous veins
OBJECTIVES
Define the clinical, etiological, anatomical, and pathophysiological conditions of chronic venous valvular insufficiency used as indicators for vascular laboratory venous testing
Describe both direct and indirect noninvasive vascular testing performed by vascular laboratory personnel
Describe protocol differences based on the objectives of testing for screening, definitive diagnosis, pretreatment mapping, peritreatment imaging, and procedure/patient follow-up
Define the role of duplex ultrasonography in the evaluation of patients with lower extremity venous valvular disorders
