Abstract
BACKGROUND: The small saphenous vein (SSV) is affected in 15% of chronic venous insufficiency (CVI) cases. Conventional surgery is the standard technique for treatment of SSV insufficiency, but sural nerve injury is a complication of great concern. Endovenous laser ablation is a surgical technique for treatment of CVI that is considered likely to reduce morbidity and mortality.Entities:

Proposal for classification of the results of Doppler ultrasonography of the saphenopopliteal junction after thermal ablation.
| J0 | Absence of patent stump | |
|
| ||
| J1, J2, J3, J4 etc. | Junction with patent stump length of 1, 2, 3, 4 cm etc. | |
| R+ | Reflux | |
|
| ||
| R- | No reflux |
J1: saphenopopliteal junction 1 cm in length, J2: saphenopopliteal junction 2 cm in length. J3: saphenopopliteal junction 3 cm in length, J4: saphenopopliteal junction 4 cm in length.
Comparison of diameters of small saphenous veins and change in venous clinical severity score at different times.
