BACKGROUND

Chronic venous disease demands clinical assessment, quantification of hemodynamic effects, and definition of anatomic distribution before diagnostic and treatment decisions can be made.

METHODS

This is a prospective study conducted in 2015 with a sample of 1,384 patients (2,669 limbs) aged from 17 to 85 years, 1,227 of whom were female. The most common symptoms reported in response to the questionnaire were pain, tiredness, feelings of heaviness, burning, cramps, and tingling. Subsets were formed on the basis of number of limbs distributed by sex, body mass index, and age. After definition of subsets, Doppler ultrasonography was used to conduct examinations of the great saphenous vein (GSV) and patients were distributed into three clinical groups (I: symptoms present and varicose veins absent, II: symptoms absent and varicose veins present and III: symptoms present and varicose veins present). Statistical analysis employed the chi-square test or Fisher’s exact test to test for homogeneity between groups. When associations significant to 5% were detected, odds ratios were calculated.

RESULTS

For both sexes, the chance of GSV insufficiency was 11.2 times greater in group III. Among cases with morbid obesity, the chance was 9.1 times greater in the same group. Additionally, patients in this group with ages ranging from 30 to 50 years exhibited a 43.1 times greater chance of GSV insufficiency.

CONCLUSIONS

Insufficiency of the GSV was significantly more frequent in group III, both overall and when considering only cases with morbid obesity, or cases in older age groups.
