Abstract

Objective
Endovenous ablation can sometimes be challenged by the anatomical factors of the great saphenous vein (GSV). We aimed to evaluate the distribution of reflux and anatomical location of the GSV.
Methods
We retrospectively reviewed ultrasound images of limbs with varicose veins who underwent surgery. We evaluated the distribution of reflux and depth of the GSV, as well as the access site or ablated extent.
Results
A total of 549 limbs with GSV reflux in 450 patients were included in this study. The distal end of reflux was located in upper thigh in 9 (1.6%) limbs, mid-thigh in 41 (7.5%) limbs, lower thigh in 157 (28.6%) limbs, and below the knee segment in 290 (52.9%) limbs. The depth of the GSV was greater than 5 mm in upper thigh only in 25 (4.6%) limbs, from the junction to mid-thigh in 49 (8.9%) limbs, to lower thigh in 82 (14.9%) limbs, to the knee in 22 (4.0%) limbs, below the knee in 75 (13.7%) limbs, and in the entire length of the leg in 296 (53.9%) limbs. Lower thigh was the most frequently accessed site for the endovenous treatment.
Conclusion
Although reflux was distributed to the BK segment of the GSV in the majority of limbs, the ablation segments were often limited by the superficial location of the GSV.
