The Effect of 0.5% Sodium Tetradecyl Sulfate: RESULTS
No patients were lost to follow-up. Five venous lakes cleared after a single treatment, four after two treatments, two after three treatments, one after four treatments and one after five treatments. The average number of treatments needed to achieve a complete cure was 2.15 ±1.28 (range 1 to 5) and the average infused volume of STS was 0.09±0.05 cc (range: 0.05 to 0.2). After treatment, all of the patients’ lesions were completely cleared (Fig. 2). No patient experienced any recurrence with a mean follow up of 29.58±13.48 months (range 10~49 months) and there were no side effects such as swelling, inflammation, skin necrosis or hyperpig- mentation. During injection, some patients felt light pain and paresthesia, but this soon disappeared. The details of the long term follow-up results are summarized in Table 1.
