At this time, there isn't a consensus pertaining to what sclerosing agent is only in dealing with macrocystic LMs, While bleomycin is perhaps the most researched sclerosing agent. The rate of profitable bleomycin procedure, described as >50% reduction in lesion sizing, varies amongst 80% and 95%.
J. Hemangiomas and vascular malformations in infants and youngsters: a classification based upon endothelial traits.
