Correlation between Times of Valvular Regurgitation of Superficial Femoral Vein by Contrast-Enhanced Ultrasound and Clinical Severity

Objective: To explore the relationship between times of valvular regurgitation of superficial femoral vein detected via contrast-enhanced ultrasound and clinical severity. Methods: Retrospective analysis were applied in 55 cases(63 lower limbs) with different clinical stages of primary deep venous insufficiency(PDVI), times of valvular regurgitation of superficial femoral vein were examined by contrast-enhanced ultrasound. Results: There were no relationships between times of valvular regurgitation of superficial femoral vein and clinical severity. Times of valvular regurgitation of ulcerative and nonulcerative limbs presented significant difference in statistics(P0.05). Conclusion: Times of valvular regurgitation of superficial femoral vein detected by contrast-enhanced ultrasound may act as a predictor for ulceration development in limbs.
