ABSTRACT

Objective: To determine the prevalence of small saphenous vein reflux (SSVR) in patients with uncomplicated varicose veins, using color-flow Doppler ultrasonography. Method: Over an 18-month period, a total of 1,953 patients underwent color-flow Doppler ultrasonography for evaluation of venous disease. Out of the total, 1,631 patients with primary uncomplicated varicose veins were selected for this study: 1,383 (84.79%) patients were female and 248 (15.21%) were male. Mean age was 42.9 (± 0.48) years, ranging from 13 to 85 years. Of the 1,631 patients, 1,323 underwent bilateral examination and 308 unilateral examination, for a total of 2,954 lower limbs with primary uncomplicated varicose veins studied. The number of right lower limbs studied was 1,461 and the number of left lower limbs was 1,493. All exams were carried out using the same protocol. Result: Out of the total number of 2,954 limbs, SSVR was detected 372 (12.59%) limbs. Prevalence of SSVR in males was 14.08% and in females was 12.35%. SSVR was detected in the right lower limb in 12.05% and in left lower limb in 13.13% of the cases. SSVR was significantly more common in patients older than 60 years. Conclusion: SSVR is relatively common and its presence should always be investigated in patients with primary lower limb varicose veins. Abstract

    ABSTRACT: Aim. It is estimated that between 5% to 20% of the adult population in developed countries is affected by chronic venous insufficiency (CVI), thus being the most frequent vascular disorder. Recent studies show that, in most CVI patients, their junctions are competent and the correlated superficial reflux is present along the saphenous vein. Objective of the study was to correlate the presence and distribution of reflux in the saphenous vein with the signs and symptoms of CVI, through CEAP, in female patients. Methods. Record review of patients with CVI signs and symptoms who underwent clinical and ultrasound examinations in order to classify them according to CEAP. The sample was divided into three groups according to the presence of saphenous vein insufficiency: Group I-SSV, Group II-GSV, and Group III-SSV and GSV. Results. A total of 312 lower limbs of 259 female patients aged between 15 and 85 years were examined. The most prevalent clinical classes in the three groups were C2 (44.55%) and C3 (46.48%). Four patterns of reflux were identified in isolated SSV, with the highest incidence of proximal reflux (69.23%). SPJ impairment was most likely to occur in clinical cases of greater severity. Five patterns of reflux were identified in GSV, with the proximal one the most prevalent (64.42%). Conclusion. There is a correlation between the clinical severity of CVI and the reflux along the SSV in association with GSV; the risk of moderate to high clinical severity in group III was 3.6 times higher than in group I and 4.6 times higher than group II.
