In a series of 50 patients treated with EVLA for insufficient GSV above the knee, a technical success of 100% was reported after a median follow-up of 7 months, but this was accompanied by nerve damage in 8%. A recent study evaluating MOCA for the treatment of SSV reported an anatomical success of 96% without any nerve damage or other major complications. Therefore, MOCA could be an alternative for the treatment of various insufficient varicose vein segments without causing nerve damage.
