ABSTRACT
Objective To assess the effects of treating varicose vein with endovenous laser treatment(EVLT). Methods 810nm wavelength diode laser machine was used to treat 170 patients with varicose veins of the legs. After treatment, leg bandage compression was used for 2 days, and then changed to elastic stockings for 6-8 weeks. Patients were examined with Doppler ultrasound at follow-up. Results Post-operative follow up(1-12 months) of EVLT in 170 patients indicated 100% rate of greater saphenous vein closure on Doppler ultrasound, and no significant complications. All of the symptoms, disappeared or were significantly improved. Conclusions The results of EVLT of varicose veins have been favorable. This minimally invasive technique appears to be safe, and results in very effective closure of great saphenous vein.
ABSTRACT
ObjectiveTo evaluate the effect of varicose vein of lower limbs treated by intravenous laser treatment .MethodIntravenous laser apparatus combin ation with operation was used to treat the varicose vein of the lower extremi ties in 98 patients(all 118 legs).The change of symptoms and signs were recorded and compared before and after operation by using venous ultrasonagraphy and pa thological examination to evaluate the treatment effect.ResultsIn the 84 followed up patieats (104 compromised legs),dull,heaviness were rel ieved completely after operation in 87 legs(83.7%),decreased in 11 legs(10.6%); skin pigmentation obviously decreased in 37 of 44 legs(84.1%);superficial varic ose vein disappeared in all the patients.No blood flow signal was detected in 10 1 legs(97.1%) and slow blood flow in 3 legs(2.9%) were detected by ultrasounogr aphy.Pathological examination revealed various degeneration and necrosis in ful l layers of the vessels;and smooth muscle cells were disrupted,cell nucleus bec ame pyknotic, the internal and external elastic laminar were ruptured and no inflammatory cell infiltration in the lumen and wall of the vessels were seen .ConclusionsIntravenous laser treatment is an ideal method in the treatment of varicose vein of lower extremities .
