stump lengths were measured using duplex ultrasono-
graphy (DUS) within 1 month and 6 months after treat-
ment. The Venous Clinical Severity Score (VCSS) and
Aberdeen Varicose Vein Questionnaire (AVVQ) score were
used to assess clinical outcomes.

Results:
A total of 97 veins (64 great saphenous veins and 33
small saphenous veins) were analyzed. The stump length
was not significantly different between the two groups
at <1 month (P=0.311). However, the stump length in the
CAC group was significantly longer than that in the RFA
group at 6 months (P=0.004). At 6 months, the mean
change in stump length was 1.41±2.28 cm in the CAC
group and 0.51±0.54 cm in the RFA group (P=0.006). The
VCSSs and AVVQ scores significantly improved after both
procedures but were not significantly different between
the two groups.
