BACKGROUND. Ambulatory phlebectomy, as described by Muller, is a remarkable esthetic, effective, and cost-sparing technique for definitive removal of varicose veins. As this technique is becoming more and more popular, potential complications and incidents have to be recognized by all phlebologists. OBJECTIVE. TO review all possible complications after ambulatory phlebectomy and establish their frequency, relevance, treatment, and prevention. METHODS. Extensive review of the European and American literature devoted to phlebectomy, with particular consideration of the complications, ape discussed in comparison with the author's personal experience. CONCLUSIONS. Notable adverse incidents after ambulatory phlebectomy are rare. Minor inconveniences are common, depending partially on surgical indications, operator's skill, and experience. Adequate training allows one to minimize untoward reactions. A great risk of ambulatory phlebectomy is the presumed facility of this surgical technique combined with ifs easy accessibility to poorly trained physicians in phlebology and dermatologic surgery.
