Treatment options are limited due to incomplete understanding of LM pathobiology. Expression of an activated \u03b22-adrenergic receptor has been described in LM tissue, suggesting that this pathway may contribute to the clinical manifestations of LM. We hypothesized that propranolol, a \u03b2-adrenergic receptor antagonist, might improve symptoms of patients with LMs and lymphatic anomalies. A retrospective chart review of patients treated with propranolol as an adjunct therapy was conducted; analyses included demographic characteristics, clinical features, and response to propranolol. Three patients with cystic and noncystic LMs displayed clinical improvement at a minimum dose of 0.7 mg\/kg\/d, whereas symptomatic relapses were observed when propranolol doses dropped below this threshold. Two patients with Klippel-Trenaunay syndrome demonstrated partial clinical responses with reduced edema. The fetus of a mother treated with propranolol from a gestational age of 35 weeks through delivery displayed arrested growth of a cervicofacial LM. Our retrospective review suggests that propranolol improved symptoms in a subset of patients with lymphatic anomalies. Propranolol treatment may also limit the growth of congenital LMs in utero.<\/jats:p>","DOI":"10.1542\/peds.2015-4545","type":"journal-article","created":{"date-parts":[[2016,8,25]],"date-time":"2016-08-25T09:07:21Z","timestamp":1472116041000},"source":"Crossref","is-referenced-by-count":24,"title":["Initial
