VenaSeal^® (Medtronic, Santa Rosa, CA, USA) and VenaBlock^® (Invamed) are the most commonly used CAC-based products worldwide.

In total, 1882 extremities from 11 studies using VenaBlock^® and 524 extremities from eight studies using VenaSeal^® were included and compared. Both devices were effective, and their cumulative recanalization-free survival rates were similar (P=0.188) at the 6-, 12-, 24-, 36-, and 60-month follow-ups. Both products improved the venous clinical severity score (VCSS) and quality of life (QoL) scores. VenaBlock^® and VenaSeal^® are effective in terms of cumulative recanalization-free survival rates, and no significant difference was found between the two groups (P=0.188).
