Sclerotherapy of telangiectasias: A prospective, randomized, comparative clinical trial of hypertonic glucose versus sodium tetradecyl sulfate

Abstract

To compare the disappearance of the telangiectasias after sclerotherapy with 75% glucose (HG) versus 0.2% sodium tetradecyl sulfate (STS). This prospective, randomized clinical trial compared the results of sclerotherapy of the telangiectasias with HG and STS. The primary efficacy end point was telangiectasia disappearance within 14, 28, 42, and 56 days following treatment. The clearing of the vessels was assessed using a six-point scale (from 0 to 5). A total of 159 women were treated (81 in the STS group; 78 in the HG group). The median score of the vessels clearing (IQR) was significantly lower in the STS group than in the HG group: 3 (2–4) versus 4 (3–5) after 56 days, p < 0.001. Pigmentation was frequently observed in the STS group (38.3% vs 2.6%; p < 0.001). In conclusion, throughout the entire follow-up period, sclerotherapy of telangiectasias with glucose was significantly superior to that with STS. Moreover, pigmentation and intravascular clots frequently occurred with STS treatment. Russian Registry of Treatment of Chronic Venous Diseases (RRT CVD) ID: VRCVD 1.005.
