RESUMEN
BACKGROUND: Venous ultrasonography identifies reflux patterns of the great and small saphenous veins (GSV, SSV), allowing evaluation of lower extremities for treatment planning and patient follow-up. OBJECTIVE: To determine progression of saphenous vein reflux patterns in women with primary venous valvular insufficiency. METHODS: Venous ultrasonography was performed in the extremities of 92 women, 43 ± 12 (23-77) years old, CEAP (clinical, aetiological, anatomical and pathological elements) clinical classes C1-C2. Two examinations were performed 33 ± 19 (8-89) months apart in patients without saphenous vein treatment. GSV and SSV reflux patterns were classified as segmental, multisegmental, distal, proximal, diffuse and normal. Prevalence was determined for each examination, separately for right and left extremities, and jointly. Prevalence was compared using χ2 statistics. RESULTS: Reflux prevalence was higher for the GSV, 89% (164/184) and 88% (n = 162), than for the SSV, 24% (n = 45) and 30% (n = 56), respectively for first and second examinations (P < 0.001). Reflux pattern prevalence was not significantly different in the right and left extremities (1.0 > P > 0.14). Most prevalent patterns were (a) GSV segmental reflux initially, 41% (76/184), decreasing to 28% (52/184) (P = 0.009), and (b) GSV multisegmental reflux at the second examination, increasing from 26% (48/184) to 40% (73/184) (P = 0.006). Prevalence of other GSV or SSV reflux patterns did not change significantly (0.88 > P > 0.19). CONCLUSIONS: We documented early findings and venous reflux progression in a specific population of women with varicose veins, reticular veins and telangiectasias. GSV segmental reflux was most prevalent initially, progressing to GSV multisegmental reflux.

OBJECTIVES: Impact of pregnancies on great saphenous vein (GSV) reflux patterns deserves clarification. Which GSV segment is most affected? Is the saphenofemoral junction (SFJ) involved? METHODS: Colour-flow duplex ultrasonography was performed in 583 women extremities with primary varicose veins (clinical, aetiological, anatomical and pathological elements [CEAP C2]), without oedema, skin changes or ulcer. Women with previous thrombosis or varicose surgery were excluded. GSV reflux sources and drainage points were located at SFJ, thigh, knee and calf. Prevalence of most proximal reflux source was noted as a function of 0, 1, 2, 3 and 4 or more pregnancies. chi(2) statistics was employed. RESULTS: Prevalence of GSV reflux was not dependent on 0, 1, 2, 3 or >or=4 pregnancies: 75%, 69%, 79%, 70% and 76% for right leg (P = 0.79) and 78%, 81%, 82%, 79% and 73% for left leg (P = 0.87), respectively. Prevalence of SFJ reflux and GSV reflux, starting at the thigh, knee or calf, was similar and showed no tendencies to increase with number of pregnancies. CONCLUSIONS: Number of pregnancies did not influence GSV reflux patterns in women with primary varicose veins.
