Abstract

Objective: The study is to evaluate the characteristics ultrasound imaging Doppler before and after the laser incineration of the great saphenous veous insufficiency at Bach Mai Hospital. Object research and methods: Uncontrolled intervention study
of 41 shaphenous veins with a diagnosis of venous insufficiency on ultrasound, indicated by 1470 nm wavelength intravascular laser burning at Bach Mai Hospital from October 2017 to 12/2019.
Results: Among 41 patient intervention. The rate of bilateral venous insufficiency was not statistically significant with p< 0,05.
Before the intervention: the mean diameter of great saphenous vein mid-thigh segment was 6,9±2,0 mm, the time of reflux in the mid-thigh was 2161±969,9 ms ( greater than 0,5s). After intervention: completely blocked after 1 month ( n=41), after 6 month (n=39), and 2 years ( n=26), not completely after 1 years, there í one case, accounting for 2,8% (n=36).
Conclusion: Great shapenous venous insufficiency have average diameter > 5 mm with reflux current time > 0,5 s. After 2 years of laser intervention, the veins were completely blocked with the rate of ≥ 97.2%.
