Re: 'Catheter-directed foam sclerotherapy of great saphenous veins in combination with pre-treatment reduction of the diameter employing the principals of perivenous tumescent local anesthesia'

摘要

We read with interest the article by Devereux et al. The authors report no benefit in terms of venous occlusion using peri-saphenous ultrasound guided tumescence infiltration (UGTI) in addition to long catheter foam sclero-therapy (LCFS) of great saphenous veins (GSV).The positive role of tumescence in foam sclerotherapy, to decrease vein size, blood content, and inflow in the target vein, has been highlighted previously.At the 2012 EVF meeting, we presented a prospective comparative study, which demonstrated better outcomes when UGTI was added to LCFS of the GSV (82.4% occlusion rate after 14 months vs. 71% in patients treated without UGTI).
