Background: In recent years sclerotherapy has increasingly become the treatment of choice for peripheral slow-flow malformations. However, the long-term effectiveness of sclerotherapy is still a matter of debate, especially when it comes to new sclerosing agents like polidocanol. This study aims at gathering further information concerning its long-term effectiveness and safety. Results: Most patients reported a reduction of symptoms which include pain (57,7%), swelling (65,4%) and functional impairment (60%). Cosmetic complaints were less likely to be reduced by sclerotherapy (44,4%). In most cases a relief of symptoms was stable for many years, especially after several consecutive treatment sessions. Complication rates were comparably low, with only 2 patients requiring additional treatment at hospital and no lasting damages. Previous studies indicate that a volume reduction immediately after treatment is the norm. However, our study suggests that these effects might not be permanent. Most patients (70,9%) were satisfied with the treatment. Satisfaction was closely linked to a partial or complete relief of symptoms (p=0.001). Conclusion: Sclerotherapy is a promising way of treating slow-flow-malformations. Polidocanol has proved to be a save sclerosing agent. The reduction of major symptoms was substantial in most cases and lasted for many years.
