Abstract    Objective    To explore effect of stripping of superficial veins in lower extremity on deep venous reflux. Methods    Forty-six patients with 48 lower extremities with combined superficial and deep venous reflux underwent the traditional surgery between January 2007 and January 2009 in the Department of Vascular Surgery, Affiliated Hospital of Chengde Medical College. Venous clinic severity score (VCSS) and color duplex ultrasound test were used to evaluate clinic symptoms and valve reflux of deep veins. Results    Forty-two patients were followed up for 2 years. At two years after surgery, score of VCSS was 1.95±1.78, which was lower than 6.33±1.78 before operation significantly (P<0.01). Deep venous reflux reduced in 14 limbs, progressed in 6 limbs, no change in 22 limbs. Deep venous reflux before and after surgery had no significant differences in the degree.Change of deep venous reflux was not different between different CEAP classification (P=0.359). Conclusion    Superficial vein surgery can relieve symptom of patients with deep venous reflux, and reduce segmental deep venous reflux in part of patients. Change of deep venous reflux is not relative to CEAP classification.
