  1. AVS success rates of published articles in last 10 years. *-This study variably reported success rates by procedure for overall and then by patient regarding left or right side. As 10% of patients had a repeat AVS, the reported right and left success rates differ from overall success. NR = not reported. Success rates depend on the strictness of criteria used to define success (Lethielleux et al. 2015), which were not standardized across these studies
