Aim: Duplex-sonography is a suitable method to evaluate the hemodynamic sit
uation in venous disorders. The aim of the study was to examine whether the
volume flow data measured in the common femoral vein are corresponding to
the grade of the venous disease. Method: In 77 healthy persons (limbs), 82
patients (limbs) with a complete form of varicosis of the long saphenous ve
in and 30 patients (limbs) with an incomplete form of this varicose type th
e venous volume flow (SV) in the common femoral vein was measured by duplex
-sonography. The evaluation of SV was done by integration of the blood flow
velocity in relation to the diameter (SV-D) and the circumference (SV-U) o
f the vessel. The location of the measurement was the common femoral vein j
ust distal the junction with the long saphene vein. The examination was per
formed in horizontal position with elevated upper part of the body (45 degr
ees). Result: We found significant differences of the means between the col
lectives (p <0,005). In complete varicosis mSV-D was 0,34 l/min and mSV-U w
as 0,37 l/min. in incomplete form of varicosis the values were significant
lower (mSV-D = 0,27 l/min, mSV-U = 0,30 l/min). In healthy limbs mSV-D and
mSV-U were 0,15 l/min. The results demonstrate a correlation between the me
asured flow volume in the common femoral Vein an the grade of the venous re
flux disease.
