A total of 29 treatment episodes were conducted for the 13 patients (1 episode for 3 patients, 2 for 4 patients, and 3 for 6 patients; the repeated treatment rate was 76.9%). The mean stretched length of coils for 1 treatment episode was 95\u2005cm. The mean absolute ethanol dosage was 6.8\u2005ml (range 4\u201330\u2005ml). In addition, 10\u2005ml of 3% polidocanol foam was injected and interstitial sclerotherapy with 150,000\u2005IU bleomycin was performed on every patient. The post-operative arterial-dominant outflow vein pressure index (AVI) increased in the 29 procedures (6.55\u2009\u00b1\u20091.68 vs. 9.38\u2009\u00b1\u20092.80,\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;lt;\u20090.05).

Local swelling occurred after all the procedures. Blistering occurred in 6 of the patients in 13 (44.8%) of the 29 procedures. Superficial skin necrosis occurred in 3 of the patients in 5 (17.2%) of the 29 procedures. The swelling, blistering, and superficial skin necrosis recovered within 4 weeks. No finger amputation occurred. The follow-up time was 6 months. The 6-month assessment of clinical improvement after the last treatment episode showed that 2 patients were cured, 10 were improved, and 1 remained unchanged. With regard to angiographic evaluation, 9 showed partial response and 4 complete response.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Embolo\/sclerotherapy can be effective and safe for hand AVM.
